ARC FAULT
Sustained arcing in PV wiring is
detected
Check DC wiring for signs of arcing or
melting, especially at connectors or
terminals. Replace damaged wires,
damaged connectors, or tighten terminals.
Need to recycle power to Inverter to restart.
INTERNAL
FAULT
Failure of self-test on internal
converters in Inverter
Need to recycle power to Inverter. Inverter
will retest relays during Start-up sequence.
If Fault Message occurs again, contact your
local service.
GRID FAULT Utility is not available
Check circuit breaker of circuit connecting to
Inverter.
Check configuration to see if it matches Grid
nominal voltage.
Inverter will automatically reconnect to Grid
when Grid voltage and frequency is within
operating range. Refer to Specification
section of manual.
PV VOLTAGE
HIGH
PV array voltage is higher than
PV operating range.
Check voltage of PV arrays.
Inverter will automatically reconnect to Grid
when PV voltage is within operating range.
Refer to Specification section of manual.
PV VOLTAGE
LOW
PV array voltage is lower than
PV operating range.
Check voltage of PV arrays.
Inverter will automatically reconnect to Grid
when PV voltage is within operating range.
Refer to Specification section of manual.
