FCC compliance
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.
Arc detection / in-
terruption
The inverter is equipped with an integrated arc fault circuit interrupter, that detects and ex-
tinguishes serial arcs.
For example, a serial arc can occure after following errors or situationes:
- Inproperly connected DC plugs
- Defective connection sockets of solar modules
- High-resistance brazed joints between the cells of a solar module
- Cables connected improperly to the input terminals of an inverter
- Defective DC cable, enabling a connection to ground
If an arc is detected, the inverter shuts off and feed-in power into the grid is interrupted. A
state code is shown on the display.
The state code shown at the display must be reset manually before the operation of feed-
ing power into the grid can be resumed.
By shuting power off the serial arc is extinguished.
Standards and
regulations
Your inverter complies with the requirements for the following standards "Inverters, con-
verters and controllers for use in independent power systems":
- UL1741-2005
- IEEE 1547-2003
- IEEE 1547.1
- ANSI / IEEE C62.41
- C22.2 No. 107.1-01 (Sep. 2001)
- UL1699B
The ground-fault detection and interruption is in compliance with NEC 690 building code
requirements.
