Inverter Light on Panel when not on the Victron Multi 3000

Hi

I have a Victron Multi Plus 3000 on my narrow boat .

I have recently noticed that when I am connected to Shoreline that the Axon Panel I have has the Inverter Light on , when it is not on , on the Victron Multi Plus. The Shore Support On and the Correct Polarity lights are on

This applies whether the Victron is On or Charger only .

When I am not on Shoreline and switch inverter on , the Inverter light does come on , on both the Axon Panel and the Victron Multi Plus.

Any advice gratefully appreciated

Thanks

Guy
