Hello all, I am looking for a wiring diagram that shows how the AC output connections are wired to a breaker box for a typical North American home. The MultiPlus 3000 setup manual shows a pretty detailed diagram for a 3 phase deployment but nothing for a split phase 120-0-120 setup. I hope that makes sense.
I just want to use my Multis as a pass through when grid is up and a backup source when the grid is down.
In my head I would hire an electrician to come in and install a new breaker box with a 200 amp breaker, move L1, L2, and N to the new box. Let them figure out N/G bonding
Connect the HOT in for inverter #1 to the L1 side of the new box
Connect the HOT in for Inverter #2 to the L2 side of the new box
Connect the N for both inverters to the N bus bar in the new box
Move heavy 240 loads to the new box like the dryer, stove, and water heater (these wouldn't be available for use while grid is down). I know that I could have these wired to the AC2 output but I would rather not have those loads passing through the Multi because I think I am limited to 50A max pass through
The output
The output of Inverter #1 (L1) to L1 in the old box
The output of Inverter #2 (L2) to L2 in the old box
The N wires from both inverters going to the N bus bar in the old box
In my version of theory.... During normal operation while the grid is good the inverters would simply pass through L1, L2, N to the old box where the entire house is wired to
If grid goes down the inverters supply L1, L2, N to the old box via the energy stored in the batteries.
I get to take advantage of the built in transfer switches and I don't have to go around and reset the 5000 clocks in my house lol
Heavy 240 loads go unusable until grid is available
Grid comes back, the inverts switch back to pass through mode, recharges the batteries based on selected profile and life goes on.
Thoughts?
