(Inverter open-loop
self-test fault)
1. Restart inverter by turning both AC and DC switches OFF.
Wait for 1 minute for all energy to discharge and turn both
switches ON
2. If inverter cannot clear fault, replace inverter
ARC Protect
1. Check logic connector to Arc board is secure.
2. Run Arc Fault Test from “Settings” Menu
3. If Alarm re-occurs, contact CPS Service to replace arc board
or wiring box

Fault
Fault0020
(Bus over volt Hardware)
1. Restart inverter by turning both AC and DC switches
OFF. Wait for 1 minute for all energy to discharge and
turn both switches ON
2. If inverter cannot clear fault, replace inverter
Fault0060
(CPLD Fault)
1. Restart inverter by turning both AC and DC switches
OFF. Wait for 1 minute for all energy to discharge and
turn both switches ON
2. If inverter cannot clear fault, replace Control Board or
inverter
Fault0080
(Bus Hardware over current
fault)
1. Restart inverter by turning both AC and DC switches
OFF. Wait for 1 minute for all energy to discharge and
turn both switches ON
2. If inverter cannot clear fault, replace inverter
Fault
Fault0090
(Dynamic leakage current high)
Check wires of PV and ground:
1. Turn OFF AC switch to disconnect inverter from grid
2. Open fuse holders to isolate PV strings. Test strings
with meter
3. Add one PV string and start inverter to see if alarm
occurs.
4. If no alarm, turn OFF AC switches to disconnect from
grid and add in the next string. Start inverter again.
5. Continue until the string that triggers the alarm is
identified. Trace back the faulted string to find any
leakage to Earth Ground.
Fault0100
(Grid relay fault)
1. Restart inverter by turning both AC and DC switches
OFF. Wait for 1 minute for all energy to discharge and
turn both switches ON
2. If inverter cannot clear fault, replace inverter
