these small variations will have negligible effects on system voltage and frequency.
However, in an islanded condition the small amount of reactive power changes will
force the system voltage or frequency to change significantly, which will trigger the
inverter to shut down. This function is always on and cannot be turned off by the
user.
1.7 DC Ground Fault Protection
The PVI 50/60TL includes residual current detection as part of the DC ground fault
detection method as required by UL1741. If there is a ground fault in the array, the
ground fault detection technology will detect the array leakage current. The
inverter will shut down if the leakage current exceeds 500mA.
1.8 Surge Suppression
Standard 1.2/50 μs - 8/20 μs Combination Wave
Standard 0.5 μs - 100 kHz Ring Wave
1.9 DC Arc Fault Detection
The PVI 50-60TL includes DC arc fault detection compliant with UL 1699B. The
inverter detects electrical noise that typically accompanies a DC series arc. The
inverter will shut down should the arc fault sensor detect a series arc.
