PROTECTION CODES
Protect0100
(The sensor fault
of leakage current)
Recommended solutions:
1.
Restart inverter by recycling both AC and DC switches. Wait
for 1 minute between OFF and ON for all energy to
discharge.
2.
If not cleared, replace Filter board or inverter.
PV Reverse
(PV input reverse
connection)
Recommended solutions:
1.
Turn DC Switch OFF
2.
Open Fuse holder to isolate PV strings
3.
Use meter to find which PV string is connected in reverse
polarity
Correct PV string connection
PV Over current
(PV Over current)
Recommended solutions:
1.
Check PV input Current
2.
Restart inverter by recycling both AC and DC switches. Wait
for 1 minute between OFF and ON for all energy to discharge.
If inverter cannot clear fault, replace inverter.
PVVoltOver
Recommended solutions:
1.
Measure voltage at DC terminals in wire-box and compare
with reading in Measurement menu. PV voltage must be
less than 1500V in open circuit condition.
If display reading is not within 2% of meter reading, replace
inverter. If display reading is within 2% of meter reading, adjust
number of panel in the string.
Protect0230
(Inverter open-
loop self-test fault)
Recommended solutions:
1.
Restart inverter by recycling 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.

2.
Run Arc Fault Test from Settings Menu
3.
If Alarm re-occurs, replace arc board or wiring box
Arcboard Err
1.
Check logic connector to Arc board to be secure.
2.
