Ground fault de-
tector / interrupt-
er The inverter is equipped with a ground fault detection and interruption (GFDI) circuit as re-
quired 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 wir-
ing, the inverter disconnects from the grid.
Standards and
regulations Your inverter complies with the requirements for the following standards "Inverters, con-
verters and controllers for use in independent power systems":
-
UL1741
- IEEE 1547
The ground-fault detection and interruption is in compliance with NEC 690 building code
requirements.
Declaration of
conformity Relevant declarations of conformity can be found in the appendix to these operating in-
structions.
