1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace inverter
Recommended solutions:
1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace inverter
Recommended solutions:
1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace Filter board or inverter.
Recommended solutions:
1. Turn DC Switch OFF
2. Open Fuse holder to isolate PV source circuits
3. Use meter to find out which PV source circuit is connected in
reverse polarity
4. Correct PV source circuit connection
Recommended solutions
1. Measure voltage at DC terminals in wire-box and compare with
reading in Measurement menu. PV voltage must be less than
1000V in open circuit condition.
2. If display reading is not within 2% of meter reading, replace
inverter.
If display reading is within 2% of meter reading, adjust number of
PV modules in the source circuit.
Recommended solutions:
1. Restart inverter by recycle both AC and DC switches. Wait for 1
minute between OFF and ON for all energy to discharge.
2. If inverter cannot clear fault, replace inverter
Recommended solutions
1. Check logic connector to Arc board to be secure.
