The Rosie / Re: Generator Size

Last post by FNG - December 11, 2025, 06:37:14 AM

I'm running one of these to charge my batteries versus Rosie (I'd be limited to a 15A 120V input due to how shes setup right now)

https://www.ebay.com/itm/127129496258

I'd suggest multiple units to give you redundancy

I've seen a LOT of people very unhappy with those ecoworthy chargers, as they seem to be very very picky about the THD output of the generator, much like all these inverter chargers. What kind of generator are you running through those?

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.

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.

Has your beta Rosie ever been replaced? Wonder if theres something busted in it.

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.

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.

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.

That helps a LOT! Where did you get yours from?

Sorry we didn't respond on the cold temperature bug but we did find it after your explanation and fixed it in software shortly after.

The "Classic" charge controller / Re: Classic 150 -- no power

Last post by KK7PW - December 10, 2025, 10:44:18 AM

Thanks for the reply. Well -- I came back the controller this morning and realized that I had not reset the circuit breaker in my battery box. I did so and now all is working properly. Palm to forehead.

Thanks again.

The "Classic" charge controller / Re: Classic 150 -- no power

Last post by ClassicCrazy - December 10, 2025, 09:07:26 AM

If the Classic is on that means your batteries are delivering power to it.
If the Classic is not on that means no power from your battery.
Did you check voltage on the battery ?  If not it probably shut off due to under voltage protection of a cell.
If that is the case you need to charge the battery with some other source to see if it will wake up . Once it wakes up and powers up the Classic, the Classic will start charging again.
But a bms in a battery can provide power out, but it can also turn off power in if it had a reason like over voltage on a cell, or if the battery is too cold and shut off charging due to that.
Do you have an app that you can see what is going on with your battery ?
If you have a generator and battery charger, try charging the battery is probably you best bet.
Not sure what kind of battery you have, or what your loads were when you were gone , how much charging it had , etc.

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.

The Rosie / Re: Rosie breaker box question

Last post by Brucey - December 09, 2025, 08:17:31 PM

So pretty sure thats talking about installing an mnepv125 125A breaker for the hb battery positive, and an mnepv 600 for pv disconnect (same as an hb breaker box except that uses a shunt trip version of the mnepv 600)

The negative of the hb battery connection would land on the whiz bang jr shunt load side (stacking the lugs).

I wonder if I can then also run the positive into the corrosponding terminal as well...otherwise, i'll have uneven lengths of cable if I move the negative over to the epanel and keep the positive on the bus bar. And i'm guessing I would want to also move my AC charger over to the same negative lug as well? I wonder if I can triple stack it. I don't think the Rosie will accept any of my for generators for ac input directly, as it stuns to require the same ridiculous thd ratings as the EG4 units and many others.

No need to keep positive and negative cables the same length for something like an scc (even for multiple batteries in parallel its the total round trip distance that matters).

For three connections may want to just have an bus bar connected to the whizbang jr load side for the non rosie loads.

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.

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.
