Title: Barcelona BETA Testing in Montana
Post by: Weldman on March 19, 2023, 10:34:41 AM
Got 10 panels going to it in series of Trina 400W bi-facials 49.4 VOC 41.7 VMP 10.12 ISC 9.48 IMP with VOC temperature coefficient of -0.29% and VMP temperature coefficient of -0/37%.
With temperatures around mid 30's or lower I am only getting 470V at max, our temperatures can drop down to -40 here. Thinking I might put a 11th panel in series. They are 300' away running down 10AWG wire.
Got up to 17.6 kWh on first day of running.
Going to put another string of 10 panels on it in the future or 11, we will see. I would like to spank a Rosie with my inverter welding machine.

Pictures coming in next 24 hours...

Rosie should work well with a welder.   Don't think we have tried that but maybe someone else has ?

Please let us know whenever that happens, if you can.

Seems to want to jump down to 200 volts range time to time from mid 400's as my meter shows it's still getting 400 plus... Need a new cell phone to send firmware updates, hopefully to be resolved in the next 2 weeks.

I know that it will sweep down as low as it can go, around 200V, when it first turns on or at least first time of the day and possibly once in a while.  This is so that the MPPT can detect any partial shading on part of the array.    If you don't have any partial shading, then you can (somewhere in the menus)  change the sweep time which might be set to every 5 minutes or 10 minutes ?

Nice place you have there !

I think we have a few Rosies in stock if you are still interested.

New firmware being released once in a while for both MPPTs and Rosie inverter so weird things should be fixed coming up.  We are in the midst of testing newer firmware for everything now and in the next week or two.

After a while, I had to turn that audio down to warnings only but can be useful once in a while.
Actually, I think I just need to change the time for the MPPT to talk less often which I found available.

Thanks,
Bought the place on a whim on eBay 6 years ago and expanded from 22 to 90 acres and counting. No partial shading for these panels, unobstructed for hundreds of feet in all directions though does make sense. Just was looking at it for a bit as I was making a pig tail and seen it went to the deep end and thought that it was odd to sweep so far.
Not too worried about it, battery is staying charged.
My cell phone is 7 years old so trying to do any firmware update for the Barcelona is not happening till next week, need another phone that won't crash an shut off exclaiming dead battery when it's at 90% full.
This one can talk al it wants till it goes mute, after all it's in another structure right now. My Classic went mute after few hundred miles of screaming it's head off from a chaffed solar panel wire on the back of our traveling house.By the time we stopped, it sounded hoarse and then went to garble and silence.

Got a a PM from FNG he is out at a show he is supposed to be sending me a quote next week for one on the Rosie so I will see where that goes.

That is funny !

Yeah, I hate phones that won't stay on long enough to get a job done :(

Good deal on FNG  looking into that for you.

The main point is that your batteries are getting charged.   Probably a good idea to wait until a better up-coming  MPPT  code update is ready in a week or two anyway.

Got 11 panels up and Rosie came in though I question myself should I install it or wait for the replacement unit of the Barcelona for the recall. I asked for a tracking number and got no reply, same with the Rosie. Came home to find it by my mailbox which is 3 miles from where my house is.
Seems lack of communication going on a lot leaving me hanging. Should I be calling instead of emailing?

Our shipping manager has been out for a week sick, It looks like they are running behind in the Barcelona and it has not shipped yet. Tracking is supposed to be auto generated when things ship but some one may not be putting th e info in the proper place this week. I will ask again today about your Barcelona, Sorry for the delays

A auto generated tracking would be nice or a update on what is going on alone would be enough. Just the hanging in the air is what has me wondering.Take your time with getting things done right and I can wait if I know what is going on.

Whiz bang Jr is in the Rosie and there is two spots for it to wire into, one in the Rosie the other in the Barcelona. Which direction do I go, and this is fun trying to figure out the whole Barcelona with breaker panel and the Rosie with breaker panel. I think this wire goes here zapp... ooh that tickles, lets do it again.

Will say the screw holes on the Barcelona with breaker box don't line up well on the back plate. Either put all screws in the CC or two screws in the CC and all in the breaker box unless one milled the holes out longer. Hope y'all don't take this as a complaint just reporting what I observe as with everything I have posted and will post on these units. I can get video of it if y'all want to see what I am talking about. The Rosie with breaker box bolted up great to the back plate. I will be getting a video of it welding and taking it beyond its limit doing so.
Great work overall!!!
Title: Re: Barcelona BETA Testing in Montana
Post by: boB on May 15, 2023, 12:57:09 PM
Thank you Weldman !

You may be seeing what I was also seeing when I put my system together for testing.

I thought that the battery bus bars (and PV in ?)  were maybe keeping the breaker box from bumping up right against the charge controller but it might be something else.

I know it was looked at but needs to be re-looked at I think which can happen this week.

It also mounts up crooked if you look at it from the sides. It's not a straight horizontal line from back to front of the unit and breaker box.

I received the backplates from Midnite for the Rosie and Barcelona yesterday. The Rosie backplate was fine. The Barcelona backplate was damaged: the bottom corners were bent, but fairly fixable. The packaging was essentially just a cover, no protective structure around the product. The Rosie plate was well packaged (larger than the unit). FYI.

Post by: Robin on May 18, 2023, 12:53:47 PM
We screwed up and are elongating the mounting holes on the breaker boxes so the two parts mate better. I hate to say this, but can you file the four mounting holes for a better fit. We did not ship very many units and back plates before this was noticed, but unfortunately you got one.
Sorry,
Robin

I'm just running it like it is with 6 out of 10 screws in. These units aren't light lifting them up and down then taking wires in and out too. Plus with ever changing weather conditions out here on top of trying to keep a flock of ducklings and goslings warm that depend on the unit then the time it would take to ship anything out here and bring the old one back is arduous with living 50 miles from the city on a gravel road for 30 miles to get to town. Lastly mail only delivers 3 days a week here and overnight or 2nd day delivery doesn't exist here. So might want to cancel your Amazon prime account to live here.
Bought the the unit at a discount price as a ß version knowing it will have flaws to help better the product and know if any safety is compromised you guys would fix it, so I'm happy with it.

So how do I get Rosie to communicate to the Barcelona. Says no inverter on the MNPG on the Barcelona. Can out to Can in from Rosie to Barcelona?
Title: Re: Barcelona BETA Testing in Montana
Post by: boB on May 21, 2023, 02:32:04 PM

It should not be the case but you might try turning off the battery to everything and turn it back on again ?

The canbus cable daisy chains from MNGP2 on the Barcelona to the Barcelona and then to the Rosie, usually.  Plug in the little terminator plug to the empty canbus connectors on each end of the cable.

I think that's what I meant was run a cable from Rosie from the Can Out port to the Barcelona Can In port or where ever it goes I haven't opened it up to look yet on the Barcelona.

I liked welding with my millermatic 180 and Rosie.  NO issues so far, but I did not weld with the thickest steel.  I used what I had in the scrap bin.  More welding to come next month on a project.

There is a separate manual for the HB BB, but I don't see one (used to be there) now for the Barcelona BB.

The jpegs below 9918 (dlattach) have no thumbnails and give a "file not found" when clicked.
9918 is posted by Wizbandit #42 on the "New Communication Box" forum. They all used to work.

Hi Raster.

I do not have a copy of the MNBARCBB manual,  cannot find one on the MN Solar site,  and have not seen it here, or there  ...   do have a paper copy that came with the BARC& BARCBB Betas.

In my environment,  post #42,  is NOT by Whizbandit,  but by qrper, Mike,  and the images in that post are in a Quote  ... Post #41,  IS by Whizbandit,  has working thumbnails (here), and is from the Rosie  ...

EDIT: >Raster,  I just went throough some of the  Posts in the "Hawke's Bay in Wisconsin" Thread,  and,  YES, none of Classic Crazy Larry's posts, with images,  show as images,  just "File Not Found",  AND,  YES,  no Thubnails there,  as you noted.  Hope that these images can be restored.<

Could you please send a message to Ryan (FNG), regarding the manual situation?

 just a drive-by. FWIW, YMMV,  and so on,  Vic

Hello Vic:

This is the #41 (May 18th) I was referring to: https://midniteftp.com/forum/index.php?topic=3587.30. I can see those jpegs about the fine dashboards, and Wizbandit was the poster. The images are very valuable for getting good ideas on how to build things.I plan to use Node-Red (data collection), InfluxDB, and Grafana (RPi)to monitor everything live. Hope the CommBox will be the bridge or provide the web interface (dashboards) directly, or at least the data formats.

I called tech support a while back and reported the jpeg and BB manual issues. She verified the problems, but haven't had any reply or followup, so just repeated everything here.

I have seen this happen with a few posts.  Usually with some of the older ones.  I just assumed that the new forum didn't get all of the old files brought over.

Regarding the ones you specifically mention.  Post 42 and 41 they seem to be working for me in MS Edge and in Chrome.

It turns out that our forum server was 99.999%  full and I.T. had to remove a bunch of stuff.

ALL of the older posts are backed up.   I am hoping that these backups can be re-instated at some time.

Anyway, it was either clean out some space or the server was going to go away immediately.

Hi boB,  thanks for the explanation.

It seems that, often, we post unnecessarily huge images,  probably because, that is the way that they come from our devices.  Sometimes, they are so large,  that it is difficult to even scroll around to get an idea of what is being shown.

There are image sizers,  but, depending on the device that has stored the image that they come from,  it can be a bit difficult to resize them.

This is a great Forum, which has been very useful, to me.  Thanks MidNite and to those, like you, boB who tend it.

73, Thanks,  Vic

Don't worry I got something that will toss it in for a hissy fit. Just knowing I can run that at max settings no problems is nice, I don't ever run it that high ever hardly. Inverter welders and such electronics make life out here easier.

Temperatures are dropping down to -35°F, right now it's -15°F and tad bit sluggish on display the Barcelona and Rosie in the elements are still working. Winds are pushing around 30 mph, feels like -47°F with windchill down to -60°F
Title: Re: Barcelona BETA Testing in Montana
Post by: Weldman on January 13, 2024, 01:53:48 PM
Welp I have pushed Barcelona to her breaking point, she should come back when temperatures increase or I take a panel offline I hope. At -35°F it was barely manageable to read the display, but she was resting when sunlight is out. Popped cover off and said 690VDC on initial contact a few times when testing, but idled down to 560VDC after a second. So I guess the unit is in self preservation mode?
Don't see how it got so high when the VOC is 49.7VDC per panel, there is only 11 panels in series and there is 300' of cable for it to send down 10AWG sized wire.
Title: Re: Barcelona BETA Testing in Montana
Post by: Weldman on January 13, 2024, 04:53:33 PM
Got system back online after taking two panels off, reset the unit including the inverter Rosie and now Rosie is not communicating and is not seen on the Barcelona. I can't find a answer anywhere, good thing I don't rely on solar system for heat. I hooked up a old Aims inverter and got power, at least I don't need a update or program to run it.

This is about the dirtiest hack I have done in emergency to keep lights on. Be nice to have emergency phone number for when these systems go down in emergency situations. When frostbite can set in, in 5 minutes to exposed skin you aren't taking gloves off to make this pretty.

Rosie is back online. After pulling covers off I took a torpedo heater and put some heat to it, it fired up in 10 minutes. WARNING, DO NOT SHUT THESE UNITS OFF IN SUB ZERO TEMPERATURES, THEY WILL NOT I REPEAT NOT TURN BACK ON!!!

What kind of batteries do you have again ?

I can say even at -12°F it wasn't coming back online, I believe around 0 to 10°F it came back online based on how long I put the heater on it. I have a FLA forklift battery, I'm just going to take the whole unit and put it in a bunker with the battery in a separate compartment so it doesn't off gas onto the electronics soon as we get above 30°F.

Want me to test all of Midnite's products down to -50°F and up to 115°F just send them here and I can do just that in a year. ;D If they can survive here, then they can survive anywhere in the US!

I guess we spec the Rosie down to -20 F or is that -20 C ?  I will have to look.

But once you get to -35 to -40 they are about the same.   -40 I think is the crossover where they are equal.

When you heat those units up with your radar heater, the temperature you measure on the outside of the unit is probably still going to be a bit warmer than the inside and whatever component is keeping it from turning back on.   Low temperature operation is a good thing.   But we have lately been more concerned with and spending more time on operational characteristics than lower temperatures.

What you have shown here is very good to know as our temperature chamber is being used for another product right now.   We'll get to this sooner than later I hope.
Really all we have to do is to spray some freeze-mist into various areas of the Rosie or whatever unit to see what makes it not turn on at cold temperatures.

Stay tuned !   I'm sure we can use your help.

It's spec down to -4°F which would be -20°C and the unit will stay on, but if you turn it off even for a second which is what I did, it didn't come back on. All I did was flip the panels off on Barcelona, disconnected two solar panes, turned battery input off, turned battery input off Rosie and flipped the main shutdown that shuts whole system down in one throw. Turned it back on and Rosie wasn't having it. We got down to -40°F after all was said and done with -65°F windchill. When you hit -40° is when it evens out.

What I can do is if y'all really want to in the name of science as this will suck for me to do, but in the name of science I can shut the unit down again and this time crank up the FLIR and record the results. This was yesterdays picture of surface temperature.

Quote from: Weldman on January 13, 2024, 01:53:48 PMWelp I have pushed Barcelona to her breaking point, she should come back when temperatures increase or I take a panel offline I hope. At -35°F it was barely manageable to read the display, but she was resting when sunlight is out. Popped cover off and said 690VDC on initial contact a few times when testing, but idled down to 560VDC after a second. So I guess the unit is in self preservation mode?
Don't see how it got so high when the VOC is 49.7VDC per panel, there is only 11 panels in series and there is 300' of cable for it to send down 10AWG sized wire.
49.7v x 11 is 546.7, With a 50-60 degree C drop from STC you are looking at 1.25 times the voltage or 684 volts

Well that should show the hardiness of these units or sophistication to shut down and able to protect itself. So the inrush wasn't lying on 690VDC, wow nice to know.
Looks to be best for where I live at to put all 11 panels back on in series, but have breakers to shut down 2 on each leg when it hits 0°F, and turn back on the 4 panels when harsh of winter is gone. I was looking at other panel brands in the 400W range and they put out even less amps than these on bifacials. That might have a factor in the high voltage too.

Well we all learned how well Barcelona can take voltage, now lets see what happens with amperage/wattage. It's 2°F with -35°F windchill we just had 6 inches of snow dumped on the panels, sun is out and I'm pushing snow off with push broom and got this brilliant idea. Get bigger cable and go 6S 2P per a channel instead of trying to push 11S per a channel as we seen how that went. Going to have to buy two more panels, but I'm not afraid of the loss they will be dragged down to run with older ones.
Keep in mind I am running bifacial panels so that's why I have 500 down for max wattage, so I can't try 7 or 8S and 2P per a channel, unless y'all want me to push it to the limits one more time.
Title: Re: Barcelona BETA Testing in Montana
Post by: Weldman on January 21, 2024, 01:39:06 PM
Alright here is something interesting. After observation of the system without changing anything with my current panels online of 9 in series on each channel (18 panels) I am getting 120+ amps which is more than enough for my 48VDC 1010Ah battery and I am seeing over 4kW watts coming in per channel. What I am getting at is I never seen these numbers this high with 11 panels in series per a channel, so even though I wasn't over voltage till it -35°F or thereabouts, it was clipping with over wattage as in trimming off a lot of wattage.

Even in the dead of summer I never seen this much wattage coming in with the 11 panels. We are currently at 40°F on the plus side of 0° right now and we were when I had 11 panels hooked up back in December and still didn't see this much wattage come in till I went to 9 panels.

I don't see 24.01.17.01 update on my MNBLE Updater. Right now when the the sun is out it refuses to hit absorption. Goes to max on bulk it can then backs down to zilch, after it is full on bulk to goes to absorption and as it comes up to absorption amperage it hits max as what the system can put in from panels and backs down to zilch again knocking the system back into bulk and bounces in bulk mode from max to zilch on amperage only never staying in absorption.

The Apple App will only access PRODUCTION updates, from what I know. You must use the Android device AND the Beta App to get Beta updates. Just another thought, though you have probably done so, after clearing the cache and deleting the App, shut down your Android device.  After restart, be sure you re-download the Green BETA App (see pic).  The Blue App will only download Production software. Your device might be defaulting to the Blue App rather than the green one.

Got the update through, still bouncing around when it comes from Bulk to Absorb mode. It is smooth in Bulk mode till it comes to Absorb and goes into Absorb, peaks at what my panels can put out then cuts out to as if I disconnected the panels and starts back over in Bulk and goes back up to what panels can put out and then cuts out and goes into Absorb repeating the process.
Anyone wants a video of this?

Think I found it, seems the float voltage was too low. So far one day without it flipping back and forth, it stayed in absorbed and went to float when it was time.

After a week since last posting I have yet to find the right settings. It will work one day correctly and next day bounce between Bulk and Absorb. Tried multiple voltages and variations based on what battery I have and none seem to work, this never happened till the updates.
Also not particularly pleased with the Rosie inverter/charger, went down in negative temperatures where Aims kept going, each time I need to hook generator up needs update or rejects the generator and there is no consistent results. It's like a guessing game each time I use it. Started off at 60 amps going in and it's causing my generator to surge I have 12kW generator so I know it's not lacking, restarted Rosie and the generator, now has 90 amps going in, generator purring along, great right? Wrong, kicks the generator off of it after a hour and I know the battery isn't anywhere near absorb at 1010Ah battery that got down below 60% full. Now as it tries to connect to generator and the amps start going up it kicks the generator off again and just loops as such till finally doesn't see generator at all. Restart system and now it's back to its surging at around 50 to 60 amps and says over current in L1 and L2.
Always fighting either Barcelona or Rosie to keep the lights on here.

I managed to graph the issue of flipping from ABSORB back to BULK dropping watts. I sent it off to engineering today.  I expect they will be investigating and working on it come Monday now that they can see it.  The reason I didn't catch it right away is my test system stays in BULK all day selling to the grid.  I will get on the team to get this fixed right away.  Sorry I missed it...

Would help to watch this unit I own and learn from it as unlike yours in a controlled environment, this one is being taken through the extremes. If this one can operate and keep going here, it will be operational anywhere in the US. We even get temperatures up to 115°F which matches Arizona.
Have no problem in feeding back data such as that MNS Combox you showed that showed the problem, small tools like that if I had my hands on helps. Help me help you guys and we can  keep ironing these problems out.

Weldman,  could you verify that when the rosie would not turn on in the cold that the batteries did not shut off?

I would also get rid of that battery switch which is most likely a 12 volt switch. All that extra wires for the battery and not being run together as inductance which is not good for the system operation. It's kind of hard to see how you have things wired with your pictures.

Rosie I am not sure we haven't been successful in recreating the cold temp shut off. I would like to swap this Rosie out for 2 reasons, 1- See if the new one fixes your issues, 2- See if we can make yours fail in the environmental chamber.

It is a 32V switch rated for 600A continuous. The battery switch has the Barcelona and the Rosie going to it both as if one would have a bus bar going to them. The negative battery wires all go to a bus bar. Other than that switch and the battery breakers on the Barcelona and the Rosie the other disconnect is the forklift battery plug outside and that isn't getting yanked apart.
Ran this combination since spring of 2023 and never had a problem till January 2024 update and the deep freeze.

Yes as I was prodding everything to see why the charge controller first went down and it's when I seen the 690 VDC on volt meter and shut everything down, went out and disconnected 2 solar panels. Went back in and turned everything on and Rosie refused till I heated it up with diesel heater as seen in the picture. Second time I did the latest update and refused to come back on till about 30 minutes to hour later with heater on it.

Weldman, when you checked and saw 690VDC on the input, how many voltage did you measure at the Rosie/Barcelona on the battery side ?

I am trying to get an idea if the battery had turned itself off.  I know you said "yes" and gave the 690V figure but I did not hear a battery voltage.   At 690 VDC on the PV input you are not going to be charging the batteries of course.

When you pointed your heater at the system, didn't the battery get warmer too ?

Sorry, I am just trying to get the whole story.   I hope we can duplicate this in Arlington with your Rosie.  I am amazed that the Barcelona capacitors did not vent.  Or maybe they did ?  Did you smell anything weird from the Barcelona ?

Went downstairs and seen it was in "Resting" mode at around 0800 hrs, looked at the voltage and it said 0 on the solar side when it was sunny outside, battery said around 50VDC on what I could partially read which is where it hoovers. Grabbed meter cause I thought maybe array went down for some odd reason such as pack rat. Put meter on it and it measured 690VDC on initial contact then settled down to 550VDC.
Couldn't see battery voltage for 100% so I put meter on it and it was around 50VDC, reached up shut the solar panels breaker down, shut the main breaker to battery on Barcelona then the Rosie and then shut the main battery switch off to both. No smell and I can smell very well as in we don't wash our clothes in any perfume detergents, no colognes, perfumes or deodorants here.
Went out and disconnected 2 panels on the end of the series, by not having both strings on the Barcelona is what I think saved the capacitors. Anyways, went back in and inspected everything looking for any magic smoke that might be escaping, checked all wiring then flipped the main battery switch on then flipped battery breaker on Barcelona and let it boot up.
Flipped solar panels on and let it register them and seen it started inverting around 580 VDC, checked with meter to make sure I was reading LCD right. Once that was operating I flipped battery breaker on Rosie, got blinking lights but not the fan coming on for test run and wasn't showing up on the Barcelona. Waited about 5 minutes to see if it would finally register, nope nothing. Turned Rosie back off and waited 30 minutes while I hooked up the other inverter which got us lights back on here. Went back and tried turning Rosie on, nope nothing, just two lights and not registering with Barcelona panel.
So I shut the unit off waited few minutes and opened the covers up, put the diesel heater on it as seen, put my hand in front to measure the right distance and let it warm up for 30 minutes. Battery is on the other side of the wall so no it didn't get warmed up at all. Turned Rosie on after 30 minutes and it's as if nothing happened. Like I keep saying it was -40°F with a -65°F wind chill that day.

Second time, I updated Rosie when it was around 12°F, it went off and didn't come back online till 30 minutes later or more as if diesel heater had no effect.
I've seen Rosie keep running when voltage has been down to 43.8VDC cause StarLink satellite dish decided to run the heater all night to keep snow off after three days of clouds.

I can upload a video with the Barcelona shut down and the covers off for inspection if you guys want?

I wonder if his devices had the "buss ID" issue where both Rosie and Barcelona picked the same random buss ID to talk on the CANBUS, a known issue that was fixed with recent firmware.  This would explain Rosie not showing on the MNGP2.  Rosie's firmware update can take up to 7 minutes to complete and maybe longer if it hits a snag and does the "revert to factory FW" recovery. This would require the FW update to be done all over again.  Rosie will refuse to turn on if the SYSTEM NAME is missing which the same buss ID's would cause.

I would check Firmware versions and update to the latest on the BETA APP.  Check Buss ID's and firmware versions after...

And that is when at 12°F it did not come back on for 30 minutes or more was the last update. I did end up waiting a few days later when it hit 32°F to try again thinking the unit was freezing and it went through then.

Forgive me if I haven't returned the other Rosie yet, I got about 60 eggs on incubation. Not a quick switch out that's easy to do before the eggs start cooling.

Here we go again.... This time Rosie did a low voltage battery disconnect, went downstairs it's -40°F flipped light switch on and the unit shut down with red light reading LBCO Disconnect, put meter on it 45.8VDC. Well it's time for sink or swim on the new Rosie unit. Flipped every breaker off, (main battery switch on the E panel crumbled in my hand) shut the whole unit down and put the new unit on. Had to bypass the main breaker on the E-panel since I can't flip the switch back on anymore so either I can have the option of buying a new breaker or could y'all send me another?
Anywho soon as I flipped main breaker on Rosie came to life without hesitation.
Reset the AAC for my generator size and cranked that up along with other settings, things are on their way back up charging.
 I hope y'all get the MNGP2 bug worked out, my battery is suffering greatly on being able to stay in either Bulk or Absorb mode.

What is your LBCO adjusted to  ?

You can turn that down to around 40V I think.

46V is fairly low.    So it won't stay in Absorb to get fully charged ?
Is the system current limited now as far as charging ?

I turned it down to I think 36VDC to try and get the unit to go back on, it was set at 44VDC and still didn't come back on. Reason it got down to 45.8VDC is cause of cloudy days which got it up to 48.9VDC before going to bed, then cold temperatures compiled onto the normal draw brought it down.
No it won't stay in Absorb (all the time), goes up to peak of amperage and drops back down as someone turned it off and falls back into Bulk, goes up to peak in Bulk and then drops back down to go into Absorb. Only two reasons it ever gets into Absorb and stays, and that's if there has been a full sunny day or I didn't drain that much the night before.
Been doing this past month or more as I brought it up before and Whiz finally was able to replicate it as a bug in the system.
Let this cold snap disappear and I will video it and my settings.

Though on a different note, when I put this new Rosie online, I now can get solar and charge the battery at same time with generator which is a big plus nice feature. Before if I turned the generator on to charge the solar would zero out till done.

Yeah, some large-ish load probably brought the battery voltage down below your 45V LBCO  long enough for it to trip off.   It has to stay below the LBCO for a minute or so for that to happen.

So, I have to assume you are using lead acid batteries.

Keep them charged so they don't freeze too.   At how low of battery voltage do you turn on the generator ?   The newer Rosie should already have decent AGS code in it with the newer MNGP2 code (if it is released yet ?)

I've got a lot of new things coming online as I build our home here and it's a touch and go as temperatures play a factor too in how fast things draw down on this lead acid battery. We've been turning StarLink off before bed cause it has it's own mind of when to turn the heating element on and off on the dish to melt snow. Didn't expect it to drop this low last night on voltage or the temperature, I also have things like heat tape to prevent water lines freezing so it's on a thermostat of when to come on or off. So many variables between thermostats and new items to draw on the system. Who knew a gas stove draws electric, 6 amps at that when the oven turns on.
There is few variables as whether to turn generator on, I keep it above 48.4VDC before hitting the generator.

Anyways I can buy or get sent to me a new battery switch for the E-panel on the Rosie, it practically crumbled flipping it off.

I don't have a AGS generator set up yet, I still need to drag that unit out of storage and plumb in propane.

Got around to putting the other string online to MPPT 2 and now it only reads one, depends on which one gets turned on first, yet says resting on one and whatever charging stage on the other. Both are on under the menu, did I miss something? Other Rosie is headed back this evening.

Hi Weldman.

This is because it is in Absorb and constant voltage.  The other side does not need to come on unless it is in Bulk MPPT  or  if the load is large enough for both halves to be working.

The Barcelona does not have 2 data registers to hold separate CHARGE STAGES for MPPT-1 and MPPT-2, I suggested it would be nice to see the status of both stages.  The MNGP2 programmer is getting his code ready, we still need to add the 2nd stage register but I'm not sure when that will be implemented. MPPT-2 is not RESTING as you can see it is providing power, MPPT-1 is actually RESTING. Future enhancement.

So that's why I have been fighting the last Rosie all this time, internal temperatures below 30°F and the bug wouldn't let it turn back on. Thought I was losing my mind there for a minute each time I did a update and it refused to come on.

Updated both this morning and Rosie came back online within 10 minutes at 18°F

What FW did you update to on Rosie? The latest test FW, 24.29.2 was working down to I understand -35C in Midnites environmental chamber, and Rosie boots up within a few seconds. I tried it a few days ago. At 43F Rosie is up and running within 2-4 seconds. Prior to the 24.29.2 FW Rosie would take several minutes to wake up at even 49F.

I updated with the newest one released yesterday. If one wants I can send it back to factory settings and redo the update this time showing in real time the time it took.

It's about 1900 hrs on this day, clear sky with just twilight and Barcelona is getting in 300W. I actually might get solar from the moon now  :o

Turned the breaker on Rosie for the generator to start charging and Rosie no longer supports a generator. AC input is Grid only and can't change it. Turned the AAC down to 8 and still kicking the generator off when usually I can turn it up to 15.

Post by: boB on March 21, 2024, 04:07:26 PM
Weldman, what is Rosie's software version ?

Can't change  the input until you  go to system menu and turn Rosie OFF  is what I am hearing.

Try that.

Input can not be changed when the relay is closed. Turn off the AC input breaker and then make the change

Spiffy new feature, I got it to work after doing as such. Still interesting to see only needing 8 AAC instead of 15, that or my generator is finally giving up.
Drawing a lot of power with 3 incubators, a brooder box, and the home on it and then a snow storm decides to blow through for 5 days.
