Presumable
Fault
E38
• Check the PV array’s insulation to
ground and make sure that the insulation
resistance to ground is greater than 1
MOhm. Otherwise, make a visual
inspection of all PV cables and modules.
• Make sure the grounding connection of
the inverter is reliable.
If this fault occurs often, contact the
service.
E40
• Check whether the airflow to the heat
sink is obstructed.
• Check whether the ambient temperature
around the inverter is too high.
E46
•
Check whether the open circuit voltage
of each photovoltaic group is ≥1020V.
If the open circuit voltage of each pv
group is less than 995V and this fault still
exists, please contact the service
personnel.
E48
•
Check whether the electric supply is
abnormal.
If the electric supply is normal and this
fault still exists, please contact the service
personnel.

• Disconnect the inverter from the grid
and the PV array and reconnect after 3
minutes.
If this fault is still being shown, contact the
service.

Check the DRED device communication
or operation.
