1.6 Anti Islanding
This inverter includes Active Anti-Islanding detection as required by
UL1741/IEEE1547. The inverter will automatically make small variations in reactive
power output in order to detect a possible islanding condition. If the grid is stable,
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.
1.7 DC Ground Fault Protection
The PVI 36TL 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 us Combination Wave"
"Standard 0.5 μs - 100 kHz Ring Wave"
1.9 DC Arc Fault Detection
The PVI 36TL 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. See section “Arc fault
current interruption” for more details.
