Newbie here, building a small off-grid backup housed in a outdoor shed. Will's book. Hours on the forums. A quick check would be much appreciated.
MPP solar 1012LV-MS 1kw 40a MPPT from Watts24/7
Two 100ah 12v LiFePO4 batteries wiring in parallel.
Four 100w panels each Voc 22.1V and Isc 5.86A, wiring 2s2p with standard 10g wire for a 15ft run at 44.2V
The 1012LV will be 2ft from the batteries.
My questions:
1. Watts24/7 included two sets of copper lugged welding wire with the batteries. A 2awg and a 4awg set, both 4ft long (8ft run?)
Which set should I use from bank to inverter? Maybe they're too long for my application anyway?
2. Should the short parallel battery jumpers be the same awg as my bank to inverter wire?
3. After the ?awg welding wire is chosen, what fuse rating is recommended to protect it?
4. I'd like to switch/break the panel array for servicing purposes. Can anyone recommend one?
Watching you guys talk/argue/hash it all out is an educational experience.
Thanks in advance for your help.
