"Each Enphase AC Battery will provide 1.2 KWh of energy storage and 275W/550W power-output. Additional modules can be easily added."
does that mean
aprox two hours of power at 500W @ 240 volts @amp?
how much discharge can the battery handle?
Seems very interesting as I have said before I am putting off updating for another year for main power supply, existing (power system) will be for overcast/rainy periods, when I get a new system.
