Hello All,
I'm attempting to draw a wiring diagram for myself before I install my Growatt 12Kw inverter and assistance is greatly appreciated from the community since I'm very Green and a newbie. The attributes for discussion are below..
Please review the installation and 12kw Growatt SPEC SHEET.
1a). I have a split phase (120V/240V) North American electricity supply with (L1 N L2) wires currently connected to my MAIN breaker panel from the meter with (L1 N L2) wires.
2a). My MAIN A/C breaker panel is in the main part of the home, I believe its an 100amp breaker box with multiple breakers to supply electricity to 120V and 240V loads throughout the main part of the home
3a). I have another sub panel connected to lights, washer/dryer, whole house water pump, etc. also with 120V and 240 loads.. Not sure about the total amperage on the subpanel breaker box to power the loads mentioned above in the home. There is no separate building for the existing subpanel. The subpanel is located in another part of the house.
I want to install a hybrid solution for my home and use the Electrical Grid for Grid-assist only in case I need maintenance on the solar equipment, or for some reason I do not produce enough kilowatts for some reason. There will be no selling back electricity to the power company(net metering). Also, I want to wire a new A/C Breaker Panel next to the Growatt 12kw inverter. I want to configure the wiring below as follows:
1b). I need to disconnect the (L1, N, L2) from the meter/grid(With assistance from a licensed electrician of course) and connect the (L1, N, L2) to a new A/C breaker box installed next to the Growatt inverter. The (L1, N, L2) wires will be used for the A/C INPUT in to the new A/C breaker box for grid-assist, and then wired to the A/C input terminals to the 12Kw Growatt inverter(Need advice on terminal connection to Growatt A/C INPUT) since this model of Growatt has A/C INPUT for (Hot-1, Hot-2, and Ground) terminal connections
Q: How shall I wire this correctly with new A/C breaker panel for split phase from the new A/C breaker panel to the Growatt inverter, since you only have an Hot-1 and Hot-2, and a Ground terminal connection on the A/C INPUT side of the 12Kw Growatt, and no Neutral terminal on the A/C INPUT side of the Growatt?
2b). I also need to wire the split phase(120V,240V) A/C output terminals(Hot-1, N, Hot-2) from the 12Kw Growatt inverter back to the new A/C breaker box, and in to the Main breaker panel in the home(L1,N,L2). I don't want to touch the already existing Main A/C breaker panel in the home, or the existing subpanel in the home. I just want to connect the (L1, N, L2) lines coming out from the new A/C breaker panel and back to the Main panel (L1, N, L2) connections in the home.
Q: Would this be the correct way to wire my specific configuration for the A/C output from the Growatt inverter?
Q: Is there anything special I have to wire in the new A/C breaker panel first before connecting any wires from the meter, or from the Growatt inverter?
The new A/C breaker panel and all the solar equipment, breakers, batteries etc, will be located in a separate stand-alone concrete shed..
Ok, I hope that I'm not confusing and way off base here with the wiring, and I'm sorry I had to talk this out instead of putting my thoughts on paper with a draft diagram. I appreciate the community assistance. Again, the electrician I'll be working with will assist me, but I want to make sure I understand what's going on, so we all are on the same page.
Respectfully,
