4 Traders Alfarad Energy

What the 4 Traders Alfarad Energy 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 4 Traders Alfarad Energy range spans 12 kW to 22.5 kW of AC output, suiting arrays of about 12–15.6 kWp at the small end and 22.5–29.3 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 10,800 to 20,250 kWh a year, assuming a conservative 900 kWh per kWp. For the smallest model, that is worth €832 a year fed into the grid at 7.70 ct per kWh, and up to €3,996 used at home instead of buying power at 37.0 ct.
