Common Fault and Information below：
Fault information
The battery connection
error
Battery under voltage
or over voltage
No grid
DC Bus under-voltage
DC Bus over-voltage
Inverter overvoltage
Inverter undervoltage
Rev 20221130
Fault reason
No battery is detected
If the battery voltage is
abnormal, the internal
circuit protection is
triggered
No grid is detected
The input is suddenly
disconnected
The rapid change of
power grid voltage may
cause high energy input
to the inverter. Internal
dc-dc converter or
charging electronics
may have a fault.
The output voltage of the
inverter is out of the
range.

Suggestion
If the battery is connected
1. Check whether the battery cable is
securely connected and whether the
battery voltage is normal.
2. If the error message remains, contact
installation partner.
1. Check whether the battery is correctly
connected and whether the battery voltage
is normal.
2. Make sure the battery is in good condition
and restart the module.
3. If the error message remains, contact
installation partner.
If the grid is connected
1. Check whether the grid terminal is firmly
connected and the grid voltage is normal;
2. If the error message remains, contact
installation partner.
1. When the fault is recovered, the inverter will
automatically return to normal working state;
2. If the external environment does not change
and the alarm remains after the system is
restar ted, contact installation partner.
1. After the fault error is recovered, the inverter
automatically restores to the normal working
state.
2. If the fault remains, contact installation
partner.
1. Check whether the external load exceeds
the specification range of the inverter. After
the fault is recovered, the inverter automatically
recovers to the normal working state.
2. If the alarm is repeated, contact installation
partner.
