Description
Step
High MPPT voltage value
1
When installing the device, measure the DC voltage with a multimeter to ensure that the voltage lies
within the MPPT voltage range.
2
If the DC voltage exceeds the MPPT voltage range, please reconfigure the PV modules. If the DC voltage
is within the MPPT voltage range, please replace the device.
3
If the error is reported for a limited period of time and the device regenerates, the cause is the
detection of abnormal device data.
4
If the device does not recover, please switch the DC and AC power supply off, wait 5 minutes and then
restart. If the error cannot be remedied, please replace the inverter.
No.:
E34/E48
Description
Step
E34: AC voltage outside the range
E48: Average voltage of the last ten minutes fault
1
Switch the AC isolator switch off and measure the AC voltage. The voltage between the line and the
neutral conductor should be approx. 230 V and the voltage between the neutral conductor and earth
within 20 V.
2
If the measured voltage is abnormal, the error is caused by the grid voltage. If the measured voltage is
normal, please switch the circuit breaker on and continue with the next step.
3
Measure the AC voltage UL1-N
，
UL2-N
，
UL3-N
，
UN-PE using a multimeter.
4
If the measured voltage is normal, there is an error in the device. Please contact customer service to
replace the device.
5
If the measured voltage exceeds the safety requirements, please check the system voltage.
No.:
E35
Description
Step
Loss of supply power
1
If the device error disappears and the device can be connected to the grid, please check whether an
circuit breaker is installed on the AC side.
2
If the error occurs constantly, please disconnect the AC circuit breaker and measure the AC voltage. The
voltage between the line and the neutral conductor should be approx. 230 V and the voltage between
the neutral conductor and earth within 20 V.
3
If the measured voltage is lower than 20 V, the error is caused by the system voltage. If the measured
voltage is normal, please switch the circuit breaker on and continue with the next step.
4

5
If the measured voltage is normal, there is an error in the device. Please contact customer service to
replace the device. If the measured voltage exceeds the safety requirements, please check the system
voltage.
