Pv terminal screw stripped

Pv negative terminal screw stripped. Can I use the battery negative to put battery negative and pv negative on same terminal.

You will have to provide more info, pv negative terminal of what device? Photo? Etc…

I have a victron 100/30 mppt controller. The pv negative terminal screw is stripped (a 4mm bootlace is stuck inside). Is it possible to connect the negative of the battery and pv negative to the one (battery negative) terminal.

You can, both negative’s are connected together internally, however i would advise to get it repaired/replaced

All good thanks
