What the Tesla Powerwall 3P, 11.5kW, 1988000-XX-Y does
A solar string inverter turns the direct current from a rooftop array into grid-quality alternating current for the home, and feeds what the home does not use into the grid. With 11.5 kW of AC output, the Tesla Powerwall 3P, 11.5kW, 1988000-XX-Y suits an array of about 11.5–15 kWp, as installers commonly size the panels up to 30% above the inverter's rating.
In Germany, an array of the same size produces about 10,350 kWh a year, assuming a conservative 900 kWh per kWp: worth €797 a year fed into the grid at 7.70 ct per kWh, and up to €3,830 used at home instead of buying power at 37.0 ct.
