Monitoring the
grid
(continued)
Your Fronius IG Plus unit determines the grid’s status by:
- monitoring voltage
- monitoring frequency
- monitoring islanding conditions
The Fronius IG Plus is equipped with a ground fault detection and inter-
ruption (GFDI) circuit as required by UL 1741 and the National Electrical
code.
Depending on the system configuration either the PV array’s negative or
positive conductor is connected to the grounding system in the inverter. If
a ground fault occurs in the DC wiring, the inverter disconnects from the
grid.
