The photovoltaic power supply inverters without transformers meet the fault
protection requirements according to DIN VDE 0100-712, IEC 60364-7-
712:2002 and CEI 64-8/7 and can be operated with a type A residual-current
circuit breaker without any functional impairment of the protection or the
inverter. The rated leakage current should be at least 100 mA per inverter.
