Hello! I want to hardwire the inverter to a main breaker box and run circuits off of that as well as a subpanel for the downstairs. I have to buy all the supplies so I want to double check my plan for accuracy and soundness.
This is an off grid system running 1200 watts (12 100watt 12 volt panels hooked up 3s4p) connected to a 50amp circuit breaker runs to 40amp charge controller, goes through another 50amp breaker goes to 4 12volt 100ah LiFebo4 batteries hooked up 2s2p runs through a 150amp t class fuse and to a 24volt 2000 watt inverter.
Now Im going to get a main panel. I think it will need a 150amp double pole ac breaker at the top. Then 2 20amp breakers (1 for each bathroom upstairs), 2 more 20 amp circuits (1 for the fridge, 1 for the freezer), 1 15amp circuit for lighting in hallway and second bedroom, 1 15amp circuit for lighting in master bedroom which will light its bathroom and closet too, 1 15 amp circuit for kitchen lighting, 1 20 amp circuit for kitchen appliances, 1 15amp circuit for lighting in living room, dining room and downstairs stairwell.
The downstairs will need a subpanel containing 3 20amp circuits (1 for washer 1 for dryer 1 for dishwasher), 2 20amp circuits for garage, 1 20 amp circuit for bathroom. I think Ill need a 100amp breaker for subpanel.
im going to need romex 12 2 for all 20 amp wiring. Ill need 14 2 for all 15 amp wiring except in locations i need 2 switches to operate the same light fixture i will need to use 14 3.
The lengths I calculate for wiring will be the run through framing studs and overhead joists and back down through studs to reach the destination.
GFCI any wet locs(bath, kitchen) AFCI in bathroom too.
what wiring is needed to connect the subpanel and does that run from a breaker in main panel, if so what size?
does this sound accurate? Am i missing anything?
Thanks!
