Common Fault and Information below :
The battery
connection error
Battery under voltage
or over voltage
No grid
DC Bus under-voltage
DC Bus over-voltage
Inverter overvoltage
Inverter undervoltage
Grid overvoltage
Grid undervoltage
The output voltage of
the inverter is out of the
range.
When the grid
detects an error, the
inverter
1. Check the grid voltage or frequency; If the power
grid voltage or frequency exceeds the allowable
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 .
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.
No battery is detected
If the battery voltage is
abnormal, the internal
circuit protection is
triggered
No grid is detected
If the grid is connected
1. Check whether the grid connection line 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 restarted,
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 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 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 .
