Over-current on the AC
side. This fault code is
displayed if the current in
the AC network is larger
than specified.
Overload on the AC side.
This fault code is displayed
if the load in the AC
network is larger than
specified.
Short-circuit on the AC
side.
The phase of Inverter can't
synchronize with the utility.
The DC component of the
electricity fed into the grid
is longer than permissible
range.
The internal temperature is
too high.
The hest sink temperature
is too high.
Description
Utility voltage greater
or smaller than the
permissible value.
Utility frequency
greater or smaller
than the permissible
value.
1. Turn off AC
breaker, then check
the peripheral AC
system configuration
and the grid
conditions.
2. If error code
keeps recurring,
contact your local
distributor for help.
1. Try to reduce the
ambient
temperature.
2. Move the inverter
to cooler place.
3. If error code
keeps recurring,
contact your local
distributor for help.
Repair
1. Wait for 1 minute, if the grid
returns to normal, the inverter
automatically restarts.
2. Check grid connection, such
as wires and connectors.
3. Make sure grid voltage and
frequency meet the proper
specifications.
4. If error code keeps
recurring, contact your local
distributor for help.
