X inverters are installed and commissioned , after few minutes some are ok but some no .
After checking the logs from inverter and alarms we discovered that x inverters have alarm 2061 abnormal grounding .
In this case next step is to check if the PE cable is installed properly inside of the inverter( depend of the type of connection ).
In our scenario connection is TT 3P+N without PE inside , in this case PE is installed outside of the inverter .
If you have more inverters connected in one daisy chain do not make also PE cabled connected as one daisy chain , because it will happen the next
If you will connect in this way , the first inverters from top will be in alarm 2061 because they will not see the
grounding , only the inverters from bottom will be ok and work because them will see the grounding.
Install the Pe in this way, each inverter need to have connected PE separately , then that alarm will be cleared and inverters will work.
If you have any issue send an email to eu_inverter_support@huawei.com .
