Fault code Description Check method
013
The grid voltage or
frequency is out of the
permissible range, and
the inverter cannot be
connected to the grid
normally.
Generally, the inverter will be
reconnected to the grid after the grid
returns to normal. If the fault occurs
repeatedly:
1. Measure the actual grid frequency,
and contact the local electric power
company for solutions if the grid
parameter exceeds the set value.
2. If the fault is not caused by the
foregoing reasons and still exists,
contact Sungrow Service.
014
The grid voltage
exceeds the preset AC
voltage of the inverter
for a long time.
Wait for the inverter to return to
normal.
If the fault occurs repeatedly, contact
Sungrow Service.
015
Grid overvoltage,
The grid voltage is
higher than the set
protection value
Generally, the inverter will be
reconnected to the grid after the grid
returns to normal. If the fault occurs
repeatedly:
1. Measure the actual grid voltage, and
contact the local electric power
company for solutions if the grid
voltage is higher than the set value.
2. Check whether the protection
parameters are appropriately set via
the APP or the LCD.
3. Check whether the cross-sectional
area of the AC cable meets the
requirement.
4. If the fault is not caused by the
foregoing reasons and still exists,
contact Sungrow Service.
016
Output overload,
The configured
module power is
excessively large and
out of the normal
operation range of the
inverter.
Wait for the inverter to return to
normal.
If the fault still exists, contact Sungrow
Service.
