Voltage problem between neutral and earth in battery operation.

Hello,


I have an old Phoenix multi 24V/ 1300W that still works. I have a problem with the neutral which generates current. I connected the phoenix to ground as well as the mppt. The phoenix is plugged into an isolated site without a generator or edf....


Should I touch J33 or something else...?

No, I plugged in a ground but I only had this cable left.


I have current in the neutral at the 80v output. Do I need to install a neutral contactor or change a Phoenix setting?


thank you

How did you measure the voltage? Against PE?

You can only measure a current if it can flow over a load.
