· DC overvoltage
A maximum
All components of the DC input are ade- quately dimensioned with a safety factor. If the threshold is exceeded, the solar inverter stops the

· AFI residual current
The AFI residual current (insulation error, ground fault) is displayed if a residual current has occurred in the PV system and the solar inverter has subsequently discon- nected from the grid. Ground faults are monitored on both the AC and DC side (universal

· Overheating fault
Your solar inverter is designed for an ambient temperature of up to +40°C. When the maximum upper temperature threshold is reached, the
