Hey all, I'm looking at the EG4 18KPVs for my father in law who will be completely off grid. We are trying to figure out different ways around the generator sizing dilemma of oversizing a generator to allow for fluctuations in load with a constant battery charge setting (Gen Size = House...

Hey, I know this is an older post but I have a similar set up right now with the evo 2.0 controller. The T1 is the hot 120 line for generator battery charging and warmer (if you have one), and in my system the return neutral runs from the generator neutral bar to my Generator subpanel neutral...

Thank you all for your replies and for confirming what I thought about how these units work. It didn't make sense to me that these couldn't be used at the same time as the inverters. I'm glad to hear others are using the CVs for this same purpose. I also have a voltage sensing relay to trick the...

I have an offgrid system with 6 48V EG4 LifePower4 batteries on busbars connected to 3 Growatt 5000ES which are in turn connected to my solar array and a 24kw generator. I'm wanting to add an independent set of battery chargers and potentially disconnect the generator from the Growatt units...

So just an update in case anyone else comes looking. I received an email back from Growatt’s service center stating that the unit does not contain any ground fault protection.

Hey all, does anybody know if the Growatt SPF 5000 ES off grid all in one inverter & scc have ground fault protection and/or pv negative bonding to ground? I’m trying to decide if I need an external GFPD but I don’t want to throw one in and bond negative to ground in a second place of the...

I bought a used fifth wheel and am currently renovating it and adding a solar system. I'll be replacing the existing LA 12V house batteries with a 12V 300Ah LiFePo4 battery bank. The RV is wired for 50A AC input. The RV already has a 65A WFCO converter that I'd like to keep using. However, it is...
