Inherited an old 12V lead acid system and ended up changing the batteries/inverter/solar panel controller. Still 12V, but now with four 206ah SOK LiFePO4 wired in parallel to a DC fuse box for the lighting, water heater and water pump; a victron mppt; and a 3000w inverter (pure sine wave) for the additional AC load.
I have two questions:
1) I have the copper ground from the old battery bank attached to the new bank, but the solar panels are grounded and am wondering if that is too many grounds?
2) Will 4/0 be overkill for recabling the DC house fuse to battery bank, the inverter to bank and the controller to bank? All the cables will be 5ft or under in length. The current cables are degrading/old and too long. I have 2awg within the battery bank.
