Dear comunity,
I am having a problem with my 3x Multiplus IIs (48/3000). (all 3 of them same issue)
Off-grid all works well.
When I connect AC IN all AC power goes to 0 or near 0, although there can be several kW of power. I read about this issue and the solution seems to be faulty current sensor Jack connector and the solution is to just plug and unplug something in there. Now the trouble is, I have a version without the jack, there are 3 pin connectors similar to the ones on Cerbo for relays.
Does anyone know solution for these models?
Thank you in advance
