Oilpan
Some of the commercial inverters can be linked adding up to a decent system. However drawing huge current on 48 VDC. Not to mention the costs of the units and heavy conductors. The wire to my inverter from the battery is only 6ga.
Here today something special. The batteries were depleted from my load test last night and this morning quite overcast. This overcast thinned and the solar panels started charging. At lunch switched to OFF GRID and the heat-pump ran for a short time until the solar Hot water system started which inhibits the heat pump.
In the grand scheme while I have good sun resource during the day the in-floor is heated with solar hot water and the solar PV is charging the pack. When the sun goes down and the in-floor has cooled the Heat-pump utilizing the stored battery power will come on line to keep us warm during the night.
Its nice when a plan comes together!!!
