No.: E46 Description
Step High DC bus voltage value
1 When installing the inverter, 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 inverter.
3 If the error is reported for a limited period of time and the inverter recovers, the cause is the
detection of abnormal inverter data.
4 If the inverter does not recover, please switch the DC and AC voltage supply off, wait 5 minutes and
then restart. If the fault 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 isolator switch on and continue with the next step.
3 Measure the AC voltage UL1-N

UN-PE using a multimeter.
4 If the measured voltage is normal, there is an error in the inverter. Please contact customer service to
replace the inverter.
5 If the measured voltage exceeds the safety requirements, please check the system voltage.

Description
Step Loss of supply power
1 If the inverter error disappears and the inverter can be connected to the grid, please check whether
an automatic recovery isolator switch is installed on the AC side.
2 If the error occurs constantly, please disconnect the DC isolator switch and measure the DC 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 isolator switch on and continue with the next step.
