Safety devices
General galvanic separation between DC and AC side, by means of a class II HF transformer
Island protection redundant voltage and frequency window monitoring (QNS); redundant switch off (independent control of 2 pole relais
and solid state switch); or ENS (VDE0126 compliant), depending on the model
Temperature protection power derating at higher ambient temperatures; switch off at 80ºC inverter temperature
DC side earth fault detection; over voltage, over current, transients (therm. guarded varistors), over power (temp. controlled derating),
reverse polarity protected
AC side over current (fuses), transients (varistors)
