So I'm considering re-designing my laundry room at the camp because I think the plan I have now will provide just enough power for a single load of laundry every 2 or 3 days and that's pushing the capabilities of the current config. So I've been thinking of stepping up to a 48v stand alone system in there since everything is 120v single phase.
I'm leaning towards a Vatrer 100Ah 16s rackmount battery because it has low temp protection and free shipping. I don't need coms or an app or interweb facepage tweeter posting and monitoring, just something I can leave on and walk away for months on end.
Currently I have:
2Kw Renogy 12v inverter
2x Vatrer 100Ah 12v batteries
Rich Solar 40a MPPT,
2x 250w panels
I'm up in the air on going for the MPP 3048 ($475) or the EG4-3Kw ($675) unit, but with my needs I can't see where the EG4 would be worth the extra $200+panels (about another $250) for the extra 2 panels I'd need to reach that minimum charging voltage.
Can anyone, especially anyone who has used either/both units, tell me why the EG4 would be the better value? Or should I just stick with the tried and true MPP 3048?
Or, considering the rest of the camp runs off of 24v, should I consider a Growatt SPF 3000-TL ($640) and use the existing 12v Vatrer batteries in a 24v or building out one of my 24v 280Ah banks I got from BatteryHookup and roll with that? I'd have to build a box, wire in a heater, convert to a 12v to feed the heater system, BMS, etc. It could easily be a spare for the cabin in a pinch...
Thoughts? Other options?
