What the KACO blueplanet 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. The KACO blueplanet range spans 3 kW to 30 kW of AC output, suiting arrays of about 3–3.9 kWp at the small end and 30–39 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 2,700 to 27,000 kWh a year, assuming a conservative 900 kWh per kWp. For the smallest model, that is worth €208 a year fed into the grid at 7.70 ct per kWh, and up to €999 used at home instead of buying power at 37.0 ct.
