Fault
Code
Description Troubleshooting
088 Arc anomaly fault
1. Stop the inverter and disconnect the AC &
DC cables. Check cable connection for aging
and looseness. Re-power on and remove the
arc warn manually.
2. Contact Sungrow if this fault still occurs.
089 Arc detection OFF warn
Remove the warn by enable arc detection
function or keep the warn by closing arc
detection function.
100
The AC output current
exceeds inverter
protection limit.
1. The inverter will resume if the output current
falls below the protection value.
2. If the fault still exists, please contact
Sungrow Service Dept.
101
The grid frequency
exceeds inverter
allowable upper limit. 1. Check the grid frequency.
2. If the grid frequency exceeds the permissible
range of inverter protection parameters, ask
utility grid company for solution.
3. If the grid frequency is within the permissible
range, contact Sungrow Service Dept.
102
The grid frequency is
below the inverter
allowable lower limit.
106
The inverter is not
grounded.
Neither the PE terminal
on the AC connection
block nor the second PE
terminal on the enclosure
is reliably connected.
Check whether there is a reliable inverter
grounding line.
If there is access to the ground, and the fault
still exists, please contact Sungrow Service
Dept.
200 The bus voltage is high.
1. Wait for inverter recovery after bus voltage
lower.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept.
201
The bus voltage is too
low.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept.
202 PV current overcurrent
1. Wait for inverter recovery after DC current is
reduced.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept.
205
AC output relay
abnormal
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept.
307 DC power is too high
Check whether the configuration of PV is in the
range indicated in the specification. If the fault
occurs repeatedly, contact Sungrow Service
Dept.
