Greeting all.
I mentioned I would post on Rosie and her trip to Guyana.
Well she made it safely with Barcy(Barcelona)with everything( panel box and wiring ) to permanently enjoy the 🌞
Had her and Barcy cleared shipping and customs on Friday.
Unpack all their stuff and had them settled in .
They will be moving in their new house 🏠 ( I mean this literally-old Genny shed)hopefully by the end of this week to start the family.
Will keep posting pics and maybe videos.
We don't have a recording team.
We are a small Country. From my local research it's the first Rosie and Barcelona in Guyana.
Congratulations.
I can confirm she is not the first in the Caricom/Caribbean region. I had my Rosie here in Barbados since last year. It is one of the beta units.
Looking forward to see the set up.
Damani
Thanks
I know saw your thread.
That's why I was specific
;D
I am looking at the AIO. it is under preorder with current connected. It's a little pricey tho.
Same here ;D ,
Dexter from Current Connected posted some pics on DIYsolar forum.
There are a few videos on utube as well, but not much about the ONE in the actual footage .
I am really liking the feature set and the usual great and best in class support from Midnite really makes it a very enticing prospect. I have had Rosie running flawlessly for nearly a year now but I need a back-up. I have had two back-up(s) failed recently (a schneider conext and a magnum pae). I have no functioning back up inverter should there be an issue with Rosie. Also I like to have hands on experience when I am recommending inverters to clients as well.
Same here we usually have plans A, B, C, D...
Our issues here in Guyana have been compounded because our grid is unreliable and unpredictable has been so and doesn't seem to be improving any time soon, because of this I usually recommend not connecting inverters to the grid for this reason even though SPDS is used.
Rosie and Barcelona up!
Installation progressed more than the pics attached but ran into two obstacles that's cause Rosie or Barcelona to be Powered up.
1. Options Board does not have plug for Arc fault toroid plug( see pic).
2.Found a neutral to ground phantom voltage of 20vac on the line intended for the AC out from Rosie.This goes to manual transfer switch that switches to Grid/Inverter( Rosie).
Not finding any faults so far.
Any thoughts on getting this fixed are welcomed.
Rechecking home wiring more thoroughly tomorrow.
Initially though it was a bad ground rod for system turned out not to be so.
Do you have any soldering skills? If not we probably will need to send a new Barcelona. I can direct you how to get to the back of that PCB to solder in a connector. Or, you could just cut the plug off and solder the wires to those two pads. Leave enough wire to splice it back if we decide to just send a new PCB or connector.
I would hate to be greedy for you to send a new Barcelona( even though I want more😁) and besides I am way over in the Southern hemisphere. I do have soldering skills but it seems a bit small for my expertises but willing to try
I also found the phantom/ghost voltage,
It was old grid power feed for outlet and light to the Genny room.
Was in the same conduit as inverter lines to the house .
Took that out completely and ran fresh cable away from inverter output wire.
Set me back two days but was worth it .I hate to see anomalies that can cause issues.
Didn't get to rectify the Arc fault
Plug issue.
Would be doing so when I get a second wbjr currently being shipped.

Kindly guide in removing the board for soldering . My soldering skills can't do it with the board on.
In the mean time enjoy some pics of Rosie and producing power,
I also had some difficulty getting Rosie and Barcelona to stay on lithium battery settings .
As of now I am depending on wbjr and charge profiles to get batteries charged to lithium configurations .These are however ok since it was what the batteries were using with old system.
See several

Also what is this Midnite ?
I am guessing an old Trace thing .
Quote
"A blank circuit board is missing it disappeared with out a Trace"
See what they did there.
So after monitoring Rosie and Barcelona .
These are a few things that is not going so well:
1.wbjr is always at 0% after two plus days( I am thinking a firmware update is needed ,was not done as yet)
2.Got a ground fault notification.(Ground fault toroid was installed and activated, Arc fault was not installed because of missing plug on options board).
Additionally,Dc negative to ground bond was not installed.As per my understanding this is created with the installation of the ground fault toroid and board.
Correct me if I am wrong.
Any thoughts on these.
Yes, the stories go back to early 1990s days of Trace Engineering when Robin started a particular, never ending story about the adventures of the Troll, Irving, and his wife or girlfriend, Mary. It always contained parts and pieces of lyrics from 50s and 60s songs and the ladies that stuffed circuit boards in production loved it when there were new stories to read. They were all too young to know what the songs were, usually. So we kind of started to continue the trend but a little differently. Doug Andrews, an old employee did a lot of what you read on MidNite PCBs. Doug also worked at Trace.
As for the apparent bugs, I will pass this on. What quarter of what year (2023 ?) was your Rosie made ?
boB
Rosie is LAST QUARTER OF 2023
Barcelona is the last quarter OF 2023
It's a bit difficult to add Pics on mobile devices.
Update on Rosie and Barc
Updated firmware using app to the most recent .
Had some issues with mngp2 update but thanks to another thread on the forum I got it resolved.
SoC still seems to be a problem though it's now at stuck at 10% instead of 0%.Will give it some time and see what happens.
I would say that's an improvement 😁😅
Update.
A re-installation of firmware solved SOC readings.
However, Rosie displayed a new behavior last night about 3am.
She decided to shut down for no apparent reason , no fault or warning.
This was confirmed from bedroom mini split shutting making the room hot and from the time reading on the bedroom clock.
I hope she is not ill.
Any thoughts on how to confirm or not she is really ill?I am hoping for a screwup on my side(setting ) rather then she being ill.She has never done this before.
Go to Setup--> Inverter Specific--> Rosie--> Event logs and give us a list of the events leading up to the outage
Will do.
Log and fault screen
more not allowed to add in one message
The only date and time log found
The only suspect I found that seems related (happened the same day today) was a blown rack and pinion DC gate motor powered by 120vac adaptor that's built in. Gate was temporarily inoperable until fuse was changed.
Additionally, a few days ago I got a ground fault notification on Barcelona. (Ground fault toroid was installed and activated; Arc fault was not installed because of missing plug on options board but new board is on its way).
After it was cleared it went away. There was no disruption in power generation from Barcelona or Rosie during this notification.
I am officially puzzled as; I was expecting something else from the logs and faults screens.
I do wonder if the Gate motor created a short on one leg that caused it to reset due to overload. I would expect an AC overload error but if it was quick enough the Rosie may overload into what we call a DESAT and if so it will reboot to protect itself without a log entry as it is primarily concerned on preservation not logs. Has it done it again?
All the numbers I see look like a couple aborted firmware updates and a lack of factory firmware, neither of those have any effect on operation

I was thinking the same thanks for confirming.
It has not done it again but I will monitor.
Will also check on the motor to see if it's probably failing.
Weird it happened around 3am ,motor wasn't even activated or running both the house and motor was sound asleep.
Guess it's early haloween.😁
Thanks guys

Sorry should have seen your earlier pics. Any issues having the Rosie and Barcie mounted so close together? My Rosie pulls in air from top fans and blows it out of the side panels, not sure what the Barcelona does air flow/direction wise. Not saying it's related to your glitch just a general question.
My hawkes bay 90A doesn't have the top fans, just the ones at the bottom pushing up the back of the rear heat sink. My hope is that will result in less operational noise vers Barcelona.
I didn't noticed any heat issues so far .
I think they both pull air from the top .
Area is pretty cool there are some shade provide by tress in that genny house converted to inverter and battery house.
Barcelona does a lot of his work during the day Rosie does not go beyond 4000w at max loads of the house.
Would say no more than 500w when the pump or mini splits aren't on.
I think I noticed turbo fans on both Rosie and Barcelona but rarely even heard either of the fans coming on to be frank.
Will definitely monitor the heat scenario though.
Update.
Barcelona has done this Ground fault detected about four times
Breakers have not tripped, which seems to keep happening in the evening or morning during the approach of twilight.
Any thoughts?
Mahendra:
I got the same just once so far (Rosie, Barcelona with RS/AFGF board). Is there an explanation from MN what this is?
R.
Raster, I think I am asking the same .
Seems like a bug to me . I have checked top to bottom and can't find a culprit.
Or maybe I am missing something 🤔

Should be able to see the temps via the mngp2.
While they pull air from the top they vent out thru the side panels, so I assume Barcelona may be pushing warmer air out directly on the Rosie's exhaust vents? I noticed also in previous notes you've mentioned your Barcelona runs hot/loud? my 450/100 pulls from bottom vents out top nothing on the sides so I could do flush side by side no problem with that design, but Rosie/Barcelona/hawkes bay seem to need more horizontal spacing.
Maybe I mistyped but the don't run warm or hot they actually run cool . Fans rarely comes on. But I may be putting one of those air directors just to be sure.

I had the issue with a Hawkes Bay CC. MN swapped out the AFGF board & Toroids and haven't had a fault since. FYI, if you do change out the board, you need to swap out the toroids as well. They are a 'matched' set, tuned by MN, must be installed as a set.

Well I should be uplifting the replacement board this week from my freight forwarding company(got a bit delayed with the strikes and all).
Will have to verify what's in the packages.

What board ?
Arc Fault and ground fault .
The one Rosie & Barcelona came with was missing a plug.

So guys I installed the arc and ground fault toroids with the new replacement board things worked great until last week when I got the Ground fault notification on the MNGP.
I should also mention that I gave Rosie and Barcelona more space apart since it was suggested that they were too close.
I'm still trying to figure out the ground fault issue.
I did catch it still doing this during twilight or as the battery transitions to float.
Don't know If that means anything.
We will be swapping out the EG4 Lifepower4 batteries with the 4 Midnite Powerflo rack batteries update to the newest firmware as well in a couple of weeks.
When you get the Ground Fault, does the Barc continue to operate or halt ops until cleared? I had the same issue with my Hawkes Bay, replaced the board & toroids twice. The Manual says when you have a Ground Fault, the system will stop until the Fault is cleared, but in my case, the Hawks Bay continued to produce power with the error message still displayed on the screen. I even connected a different set of panels using separate wiring to the HB, would still get intermittent Ground Faults. Seemed to happen most often when the sun initially came up in the morning. Lastly, I ran the same PV/wiring thru a Classic controller next to the Hawkes Bay and never received a Ground Fault! Anyway, I just turned off the Ground Fault in the software and soldiered on. My 2 cents :)

You are correct, the Hawkes Bay and Barcelona Ground fault code does not cease charging, this is a defect in the code. Also I found out the AF/GF circuit boards are "tuned" to the specific cores they are shipped with, they are "matched". Just swap the board and not the cores that go with it and bam, false alarms. Since the original programmer has left and they have no one to continue to work on it and fix the bugs it is what it is. I heard management is going to try and hire a replacement but I have no idea what the status is. That being said it will take time to get him or her up to speed on the MPPT code. I don't expect any updates for a while...

Thanks James for the info :). I appreciate the reminder about the AF/GF board & toroid 'pairing'. Ryan had mentioned that when he replaced my initial AF/GF board, but I don't think it's common knowledge as it isn't specified in the current manuals. Good to see you on the forum!

Same issue as yours
So, I did promise updates, guys.
So here they are, Rosie, Barcelona and MNGP2 updated to the most recent with five(5) Midnite powerflow batteries in closed loop communication,
Let me know if anything seems wonkers.

Looking good! That dolly for the battery stack seems to be a custom fit.
Yea ,we did some welding ,bolting and stuff to get it together.We appreciate some ease of cleaning in those corners.
Readings seems spot on so far .
We will be adding Solar assistant soon.Picking up the CAN to USB cable tomorrow.
Don't make that mistake when ordering, ensure you add cable to cart.
The nuisance ground fault trip did not reoccur since the updates and adding the powerflos .Hope it stays that way.
Well we added Solar assistant ,
But it's not going as well as I would expect.
No data on Solar assistant from Rosie, we swapped can to usb adaptor but still the same
Update!
Rosie, Barcelona and power Flo finally functioning with Solar Assistant.
Thanks Ryan@midnitesolar.
We had some hiccups but got there.
Some pics
Ryan shared this link.
It's from Amazon brand is waveshare can to usb.
I also use their rs to usb for other batteries like eg4

Sorry locally custom built.The pic show n is not the completed trolley I will post the updated one.
Once you have some fabrication skills it can be done take some time and effort though.
Dang I should have completed a CAD drawing.
I didn't relise it would have came out that good
So another update guys,
One pack in the set of four power flow batteries gave a fault for serval times on Monday.
What was weirder is that every time it went to fault the entire system was shut off without warning or any code on mngp2 .
I was not pleased with either of these .
I tried getting help from tech support but they seemed Clueless as I was.
So I isolated the one alarming pack and found everything was fine beside this pack .
I operated in this manner for two days
So the only option was to check for firmware updates .
Only updates that were available were mngp2 and solar assistant ( I don't recall if I mentioned but system is now being monitored through solar assistant)
So far this seems to be the solving the issue but the whole system shutdown and no fault code reporting is getting me uneasy.

Personally I would switch to open loop and run on voltage without any of the bms errors causing outages nonsense.
One reason someone had requested the ability to have battery comms to grab cell level data yet still run open loop based on voltage.
Yea , unfortunately owner wants the bit of autonomy.
Had another brief shut down .
At this point I can't tell where it's coming from.
I am still suspecting the one power Flo battery.
Tech support has been really unhelpful. We were given another tech support number and told to talk to Ron or Rick . They seem to be the powerflo guys.
Hope Midnite figure this out .
