Hi folks,
DIY'er here and fairly new to off-grid systems but learning! A quick brief:
I have a 2005 Class A that I just installed a Growatt 24V (3000W) AIO inverter. All is working great so far; nice unit. Still got to get the panels in but coming.
For batteries I have (2)12V 100ah Lithium LiFePO4's (with built in BMS) running in series (24V).
Q1: I have 2 more batteries coming, the same ones so I will be configuring in parallel and series to keep my 24V but double my amps to 200. I've seen some wiring diagrams but I'm just confirming what would be the recommended way to cable them up? ...more specifically, would you wire them as parallel then series or series then parallel to the inverter? Pictures would be awesome.
Q2: For the vehicle alternator side of things and charging from the workhorse chassis alternator.
I understand that there are DC-DC converters/chargers out there (Victron, Renogy etc.) so I guess my basic question is what would be the best way to charge the 4x 12V battery bank (that's producing 24V in ser/par)? I'm not sure the converter/charger I'll need and how it works exactly. I think I'm missing some basic electrical engineering knowledge here! Thanks in advance all and I appreciate all the feedback!
Cheers!
