002
Grid over-voltage.
The grid voltage
exceeds the protective
value.
1. Check the voltage of the grid.
2. If the grid voltage exceeds the
permissible range of inverter protection
parameters, ask utility grid company for
solution.
3. If the grid voltage is within the permissible
range, contact Sungrow Service Dept.
003
Transient over-voltage.
The g
rid transient
voltage exceeds the
protective value.
1. This is a short-term fault due to grid
condition. Wait a moment for inverter
recovery.
2. If the fault persist
s, please contact
Sungrow Service Dept.
004
Grid under-voltage.
The grid voltage is
below
the protective
value.
1. Check the grid voltage.
2. If the grid voltage exceeds the
permissible range of inverter protection
parameters, ask utility grid company for
solution.
3. If the grid voltage is within the permissible
range, contact Sungrow Service Dept.
005
Grid under-voltage.
The grid voltage is
below
the protective
value, which is lower
than the protective
value of error 004.
1. This is a short-term fault due to grid
condition. Wait a moment for inverter
recovery.
2. If the fault persist
s, please contact
Sungrow Service Dept.
006
AC over-current.
The AC output current
exceeds inverter
allowable upper limit.
1. The inverter will resume if the output
current falls below the protection value.
2. If the fault persists, please contact
Sungrow Service Dept.
007
Transient AC
overcurrent.
1. The inverter will self-recover after several
seconds.
2. If the fault persists, please contact
Sungrow Service Dept.
008
Grid over-frequency.
The grid frequency
exceeds the protective
value.
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.
009
Grid under-frequency.
The grid frequency is
below
the protective
value.
