Title: Generator Size
Post by: Weldman on November 27, 2025, 08:34:23 PM
Been running the Beta Rosie for about 2 years now, each time an update comes out it is either good or bad on what AAC I can charge my 1010Ah battery. Sometimes it's 18 AAC and pushing in about 80 plus amps other times it's like recent it's only 6 AAC of only 20 something amps. Running 9.5kW generator and wanting to know is my generator too small, what size should I be running or the max I need?

 A 9.5Kw Genny is a good size.  Larger than my 7.5Kw QD.  Are you saying you need to keep messing with the Charge Amps?  Why?  What is it doing that makes you change it?

Keeps kicking it off when they are too high, some updates it can run it up to around 80A, some updates only get it to around 30A.

That's not good.  I want to order one, but I keep reading about Genny issues and I only have one, so it must work whenever I need it. 

Will it still pass thru the generator power and just not charge the batteries or does it kick off the same for that too?

You can have it where it just passes through and not charge the batteries or it charges the batteries while you are pulling from the batteries. When it is charging the batteries while pulling from the battery is where my problem is. Yes I need to buy a standalone battery charger for where I live.
I live in Montana off grid as in nearest neighbor is 3 miles away, cell phone is non existent without satellite, and it's an hour to town.

After it resets itself do you have to reconfigure the battery settings and other stuff?   (if not closed loop)  -Bill

Usually after the more major firmware updates you reset to factory defaults so that any changes can take effect and make sure there is nothing from old firmware still in memory. Yes after reset , then you do have to enter all the settings again.

I would make a note of all your settings and then do a factory reset of the MNGP2 and then the Rosie.

Especially as you've been having issues with gen breaker settings.

Reset everything as needed on Rosie and the MNGP 2 still same results as if I didn't nothing except make it worse. Going into winter and just like the previous two winters, this system has me limping throughout the winter drinking was more gas than needed to keep going. Nope can't do it anymore. I will sell the unit and move on to a unit that doesn't require updates throughout the year. People in their comfy homes in Washington state don't understand as most of the US, we live off grid as in you are an hour away from any cell phone signal if power goes down which means no tech support, no downloading updates. Temperatures plummet to -40°F out here.

If it's any help, I gave up on the charger part of the "inverter/charger" units, and I don't bother with the one on my Rosie either. I use stand alones because they just work. I used to use Iota chargers, but the last three years i've been using the Chargeverter and it's done a really nice job, for whatever that's worth to you. It doesn't give two shits what your thd is, and is efficiency is about 97% when running 95a, as I run mine.

Yes it has been replaced once so far. The last time it was replaced they were trying to mimic the temperatures that are out here and supposedly were going to try it on dry ice. I asked to see what they came up when they got it and tested it, didn't hear anything back.

Post by: BlackwaterPark on December 09, 2025, 04:39:11 PM
Signature Solar. I got it when it was $350, but they are 650 now. Still worth it to not have to put up with the hassles that you are going through, imo. The tech with these inverters and all-in-ones has gotten to the point where it is more a hindrance than a benefit, from what i've experienced and seen others go through.

Mines running via grid as double conversion at 30A output but also ran it on a Honda eu2200i generator for a bit to test, no worries. Mines a v1, the current v2 model also includes a soft ramp function so it doesnt hit generator hard if you have it set for the full 60A output on 240V for example.

There quite a few of us over on diysolarforum using them and I haven't heard of anyone having issues. Any particular forums or threads?

youtube videos is where I'm seeing all the comments on it. There are two videos in which it is tested and doesn't want to work with some generators. I'm guessing they can adjust the firmware though, in order to broaden the range it will accept. If most folk are running quality inverter generators like hondas or yamahas, I doubt you would have a problem, but it's the conventional ones that become an issue...very ubiquitous gensets like the predators and champions.

This was one such, but there are quite a few other videos from different channels that are less than glowing, but it's really in the comments section that I tend to scour where I find the similar sentiments based on poor user experience. A couple, and is whatever...but when there are dozens and over several different vids, that's when I kinda take notice. I was looking for a cheaper alternative to another chargerverter to have on hand, so I was hoping the ecoworthy was a viable option, which is what sent me down that particular rabbit hole in the first place.

Oh that seems to mostly be about how the provided adaptor from 5-15 to l14-30 adaptor cord doesnt work and you need to replace the L14-30 with a 5-15 plug for 120V operation.

Depending on budget might be worth trying to run the ecoworthy with his larger non inverter generator, and then return if it doesnt work. Or I guess pony up the big bucks for the eg4 if it does indeed have a wider operating range.

The thing was a steal when it was $350. Almost double that, no longer much of a steal, but I wouldn't hesitate to buy another if I needed one. Does the ecoworthy run both 120 and 240 in? Have you ran it full bore for a couple hours? I do tend to run my chargeverter at a hair below maximum for 3.5 hours at a time, and it throws the heat out for sure, but i've run it that way many many times, so I can speak to its robustness...at least the first gen one.

Yeah been running it for 20 hours+ at a time with most of my panels totally snow covered, but its limited to 30A output with 120V input. It needs 240V to get to 60A output, which it does support but it doesnt have quick swap cables like I think the eg4 may come with? Louder than I'd like from cooling fan noise but apparently the eg4 may be even worse in that regard.
Title: Re: Generator Size
Post by: BlackwaterPark on December 10, 2025, 08:14:15 AM
yea, mine is loud certainly...but nowhere near as loud as one of my inverters (I run two completely separate systems in the same house tied into my mains with a transfer switch) when I used to use it for charging. It's a low freq unit , custom made, with these ridiculous three fans, that sound like a 747 winding up on the tarmac. It's so loud it's actually more impressive than it is annoying. Well, at least for the first few minutes.

It's a good sign that you can run for long periods of time like that, and the design of being essentially a pair of 110 chargers, sounds exactly like the chargerverter. Mine didn't come with cables though...you would have to swap the plug end or get your own adaptor. I guess one advantage of a setup like that is that if one of the chargers bit the dust, you'd at least have the other, even if limited to half functionality.

You are correct, The older firmware would not work with a few AVR's on the market. We spent some time recently and now have not been able to find a generator that does not work, If you find one let us know the make and model and we will procure one to test against.

Quote from: Weldman on November 27, 2025, 08:34:23 PMBeen running the Beta Rosie for about 2 years now, each time an update comes out it is either good or bad on what AAC I can charge my 1010Ah battery. Sometimes it's 18 AAC and pushing in about 80 plus amps other times it's like recent it's only 6 AAC of only 20 something amps. Running 9.5kW generator and wanting to know is my generator too small, what size should I be running or the max I need?
Could it be the variable loads causing this? A few things to note in no particular order
1- Breaker size is king and the Rosie will throttle the charger down to not exceed the breaker size in AC INPUT menu. So on a smaller generator if set properly the charge amps will move around based on the AC Loads
2- Newer code adds some adjustments in generator mode to allow for the full 120A charge so at the same AC Charge rate we would see more DC charge current

You are correct, The older firmware would not work with a few AVR's on the market. We spent some time recently and now have not been able to find a generator that does not work, If you find one let us know the make and model and we will procure one to test against.

I look forward to trying mine out in that case, thanks for the update!

Quote from: Weldman on November 27, 2025, 08:34:23 PMBeen running the Beta Rosie for about 2 years now, each time an update comes out it is either good or bad on what AAC I can charge my 1010Ah battery. Sometimes it's 18 AAC and pushing in about 80 plus amps other times it's like recent it's only 6 AAC of only 20 something amps. Running 9.5kW generator and wanting to know is my generator too small, what size should I be running or the max I need?
Could it be the variable loads causing this? A few things to note in no particular order
1- Breaker size is king and the Rosie will throttle the charger down to not exceed the breaker size in AC INPUT menu. So on a smaller generator if set properly the charge amps will move around based on the AC Loads
2- Newer code adds some adjustments in generator mode to allow for the full 120A charge so at the same AC Charge rate we would see more DC charge current


I have had this generator since Rosie has came out, the amount of power drawn has only changed by one freezer added to the power load in all the years. Breaker size in the AC INPUT menu has never changed it has always been 60AAC. The only change that is constant and changes is the updates. Each update brings different results of how many amps can go into the battery from charging and I have seen 80A on updates. This is the far worst one yet, I'm on 7 AAC and it's still kicking the generator off after a few minutes of running then picks it back up.

I need to record and post the results with settings I have with a video on here.

I bumped the settings up to 10 AAC to speed the results up, as being on 7 AAC takes about 5 to 10 minutes to do what it does instantly on 10 AAC.
Generator is a 9.5kW EFI (Electric Fuel Injection) can surge up to 11.5kW.

Just prior to the charging rate dropping the genny made an odd sound I have not heard my genny make before.  I believe it made it twice.

Yeah, loading the generator up with amperage that is faster than the display can show. I have caught it one time go from 20 something to 55A before the Rosie kicked it off with the generator surged as you hear when I had it set at 7 AAC. I can see it start to peg the generator out each before Rosie kicks it off as there is a status bar on the generator to show how much it's pushing.

Have you tried it in GRID mode rather than GENERATOR mode?  I am grid tied, though I use most power thru the Rosie and batteries.  I exercise my generators (2kw & 3kw Honda's) 3-4 times a year, plugged into the Rosie w/a small load and the charger on.  I keep Rosie in GRID mode and get full output of the generator into Rosie, based on what I set for the breaker input.  If I exceed what the generator can output, it will surge and disconnect as in your video.  I've found a sweet spot for each generator, aprox 2 ACC below their rated output, that runs smoothly.  I am running PRODUCTION firmware Rosie=25.9.9 and MNGP2=25.10.12. Hope you get it working well or your needs.

Wonder if the efi function is interfering/fighting with Rosie.

There is a newer PRODUCTION firmware for Rosie, 25.11.13.8 . Perhaps download and try this newer version. This pic was current as of yesterday for production software for my MNGP2, Hawks Bay, & Rosie.

It doesn't matter, beta and production units can both run either the beta or production firmware.

Midnite has not been updating the Firmware Threads lately, or I should say, it's been hit and miss.  The only way to really know is run the app every month and see if something new pops up!  I did this 2 days ago and found a new Production firmware for both the Hawks Bay & Rosie, which were not posted in the Firmware threads.

Wow, that's not great.  I checked their website and the only thing I could find that didn't specifiy some other device was a download for "Test"  and its an .apk file which is probably something for an android device.  I am assuming the Rosie isn't running the android OS.... is it?

The Midnite Rosie, hawkes bay, Barcelona and mngp2 firmware are updated via Bluetooth thru a midnite Android or iphone app.

If you look at the top of each forum for those products it should show firmware update notes, for example:

https://midniteftp.com/forum/index.php?topic=5952.15

They dont have the most recent versions change notes yet.
