The plan/goal is to have enough Battery Backup to not have to fire up a generator for 12-24 hours. with intentions of adding some solar later to supplement the generator. I have a Honda 2000i generator (1600w con, 2000w surge) I can use for backup to charge batteries and or boost the Victron inverters output potentially.
Critical loads are a full size fridge, upright freezer, 9cuft chest freezer, aquarium filter/heater, up to 50w of led lights and 50w of phone chargers.
My calculations for loads are up to 1200w constant plus an additional 1400w surge on the fridge (largest surge) for a 2600w max surge.
So far I have a Victron Multiplus 12/3000/120 with the usb adapter and Bluetooth adapter. Rated at 2400w constant and 6000w surge.
Also have a Victron 500a Smart Shunt to monitor real watts in and out of the battery.
I have 8x Lishen cells on the way for 2x 12v packs using overkill solar 120a bms's on each with upgraded 8aug wires.
Battery bank will therefore be 12v 500+ah with 240a continues discharge rating and a surge up to 560a for 10 seconds.
Still need battery/inverter cables, I figure 1/0 for each battery up to 4/0 to the inverter with as short of runs as possible of each
Also need a 400a fuse per Victron spec.
I know there are other details that I'm not thinking of right now so please let me know if I'm missing anything major.
But as far as to the overall plan and parts list does this sound like I have things figured out right?
