I have 2 EG4 48 volt 18 amp battery chargers in their original boxes. $250.00 for both. Each was used a total of 3 times.

Thanks.

I will be running four LV6548 inverters, off-grid only, configured with two inverters for each phase. The Line AC output wires run to two double pole 60 amp breakers in a sub panel. Do the Line AC output wires from the inverters to the sub panel need to be the same length? Thanks.

Thanks for responding. If I have any problems with solar (inverters), I will be able to switch to a propane generator, which is NG-bonded, with little down time which is a necessity. I'll also have two 18A battery chargers for extended cloudy days.

I've been following these threads for almost a year and consider you, timselectric, filterguy and ncsolarelectric experts. And you guys have different conclusions! So Zwy, if you had 4 LV6548s, configured 2 for each leg, off-grid only, and an inverted generator that will only be used via a...

Sorry it took so long to respond. SS suggested using multiple chargers to charge the battery bank and leave the inverters to handle loads.

Can you guys take a look at my plans for an off-grid only system for a new house? I have everything except the panels, smart shunt and battery charger. "Inside" is in an insulated shipping container. The service panel will be located at the house. I'm removing the N-G screw in both inverters...

I just found it, looks like a lot of good information. I'll definitely take my time and study what you've done. Thanks.

scottvanv is the fella I'm watching. He's further along than me. I think he's using (2) LV6548s and (32) 455W panels. I don't know what he's using for batteries. I'd like more info on his build. I need to make a correction on the well pump kit. It is from RPS solar pumps.

MrM1, I think you're suggesting what I'll probably do. (1) LV6548, (16) 455W panels, (6) EG4-LL 48V batteries, all to power the RV, a separate solar kit from unbound for the well pump, and a 9200W generator for tools. Is that correct?

RPS solar pumps sells a pump kit that will meet my requirements. It includes panels, controller and 3 phase 220v motor and pump. That would reduce the 240 load at the house to just the heat pump. I'll probably go with it. During construction, I'll be living in an RV. I will be installing a mini...

It's a gravity system, so the tank is another 100' up a hill.

The pump hasn't been installed yet. I asked the driller to if a soft start is possible. He's investigating. My well is 800' deep, water @ 620', 3gpm.

Thanks. I'll check out the LVX 6048.

Excuse my limited knowledge. Is there an advantage to the inverter being able to communicate with the BMS? I remember reading something about the inverter modifying and slowing the rate of charge as the batteries approached 100% which would increase the life of the batteries. Or is this a non issue?

MPP LV6548 or Growatt SPF5000ES? I'm building a new off grid house. The only 240 volt loads are a 3 hp submersible pump and a 3 ton Carrier Infinity variable speed heat pump. Propane will heat the water and cook the food. I have 6 new EG4-LL 48V batteries. I'm undecided on inverters. I'm...
