What the RCT Power Power Storage DC does
A hybrid inverter runs both the solar array and a home battery: it supplies the home from the panels first, stores the surplus and draws on the battery when the sun goes down. The RCT Power Power Storage DC range spans 4 kW to 9.9 kW of AC output, suiting arrays of about 4–5.2 kWp at the small end and 9.9–12.9 kWp at the large end, as installers commonly size the panels up to 30% above the inverter's rating.
In Germany, arrays of the same size produce about 3,600 to 8,910 kWh a year, assuming a conservative 900 kWh per kWp. For the smallest model, that is worth €277 a year fed into the grid at 7.70 ct per kWh, and up to €1,332 used at home instead of buying power at 37.0 ct.
