Its good to know the watts but I asked about the voltage.I'm only concerned now with the PV location in the sunny spot, and our cabin 500 feet away. I don't want to deal with 12 wires for 14 split phases in 8 dimensions for 500 feet of trenching to the cabin.
One DC wire carrying the PV to the cabin/inverter/MPPT/etc and then I'll hire an electrician to pick whatever gold plated, zinc infused, Auto Transforming Flux Capacitor he wants to make the GSHP and the cabin circuits work. Since it will be a small distance.
The PV is 22KW.
I sense that you are over this for now.
