The Rosie / Re: Generator Size

Last post by BlackwaterPark - December 09, 2025, 05:43:41 PM

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)

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.

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

Last post by KK7PW - December 09, 2025, 05:02:07 PM

Hello. Here is my system: a classic 150, 4 Kyocera KC130 panels, a MS combiner box with breakers, a Wizbang Jr., and a circuit breaker. Set for 12v. I have had my system for many years, previously used to charge four 6v batteries. I replaced those with a new 100ah LifePo4 battery. I configured the Classic 150 to properly charge this new battery. All worked fine. As I do not use the battery much, the system was simply unused (for several months) until today when I intended to top off the battery. I now have no power to the 150.

With a voltmeter, I have verified 40v coming from my panels, through the combiner box (circuit breakers work and lightning arrestor energizes properly) to the 150. I checked the terminals at the 150 and see 40v coming in. However, I see no voltage heading out to the 150v circuit breaker.

I tried resetting the breakers, loosening, removing, reinserting, and tightening the wires at terminals and still no response from 150.

Any thoughts on what else I should try? Thank you for any thoughts.

Chargeless in Seattle.

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.

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?

The Rosie / Re: Rosie breaker box question

Last post by BlackwaterPark - December 09, 2025, 12:58:46 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.
