Buzzer beeps
continuously and
red LED is on
Warning code 06
Fan fault
Replace the fan
Warning code 05
Internal temperature of
inverter component is over
100°C
Check whether the environment
around the equipment well
ventilated
Fault code 07
The battery voltage is too
high
Check if spec and quantity of
batteries are meet requirements
Battery is over-charged
Return to repair center
Fault code 10
Parallel fault
Please check if the connection
between the inverters is loose
Fault code 06
Output short circuited
Check if wiring is connected well
and remove abnormal load
Warning code 05
Overload error, the inverter is
overload 100% and overload
time reaches the upper limit
Reduce the connected load by
switching off some equipment
Fault code 22
If PV input voltage is higher
than specification, the output
power will be derated. At this
time, if connected loads is
higher than derated output
power, it will cause overload
Reduce the number of PV
modules in series or the
connected load
Fault code 02/03
Output abnormal (Inverter
voltage below than 190Vac or
is higher than 260Vac)
1. Reduce the connected load
2.Return to repair center
Fault code
01/04/06/08
Internal components failed
Return to repair center
Fault code 23
Over current or surge
Remove abnormal load or
check PV input
Fault code 01
Bus voltage is too high
Restart the unit if the error
happens again please return to
repair center
Fault code 09
Bus voltage is too low
Fault code 02/03 Output voltage is unbalanced
Fault code 11
Internal temperature of
inverter component is over
85°C
check whether the environment
around the equipment well
ventilated
Fault code 12
The battery voltage is too
high
Check if spec and quantity of
batteries are meet requirements
Battery is over-charged
Return to repair center
Fault code
13/14/15
Phase loss
1. check whether three- phase
power is connected. 2.check
whether the inverter turns on
three- phase parallel
Fault code 16
Output different
Check whether the output
voltage and frequency of each
inverter are set the same
