As regular readers know, we installed a solar power system up here at the house in Pennsylvania. The learning curve has been sharp.
We have 11,000 watts (22 individual panels at 530 watts each) of solar panels at 48 volt output each. They go into two (2) mppt charger/controllers which then go into a 30 kilowatt hour EG4 battery bank @48 volts.
From the battery bank, two 4-ought copper wires go to each of two 6800 watt inverters. The Inverters synch with each other, so the sine wave is pure 60Hz, just like normal grid power.
The 6800 watt inverters can EACH handle a needed “surge” of 8500 watts for 30 min or up to 12,000 watts (each) for one minute.
No aspect of this house, at any point, can ever come near that kind of power surge demand.
As I type this story at 8:46 PM eastern time, we have the gas furnace running, the front porch light and rear deck light on,…
