2. Run Arc Fault Test from Settings Menu.
3. If Alarm re-occurs, replace arc board or wire-box
Recommended solutions:
1. Check logic connector to Arc board to be secure.
2. Run Arc Fault Test from Settings Menu.
3. If Alarm re-occurs, replace arc board or wire-box
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. Raise limit of IDCmax (for example, 400mA) to allow inverter
more room to adjust in transient condition to cope with imbalance
of impedance and voltage between Grid phases.
2. If after adjustment, alarm still occurs, 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
Check wires of PV and ground:
1. Turn OFF AC switch to disconnect inverter from Grid.
2. Open fuse drawers to de-couple PV strings from each other. Test
source circuits with source circuit test set
3. Add one PV string at a time and start up inverter to see if alarm
occurs.
4. If there is no alarm, turn OFF AC switches to disconnect from
Grid and add in the next string. Startup inverter again.
5. Continue until you can find the string that triggers the alarm.
Trace wirings of faulted string to find any leakage to Earth Ground.
