Does anyone know if there is a relay I can get that will take the place of the manual break switch of my wind turbine so the system can turn the break on when the battery’s are full. My wind MPPT is pretty dumb and I want my Victron system to control it.
You can replace the manual switch with a contactor of reasonable rating. Bear in mind it has to take the high current from The Wind gen running at full speed. These work by shorting all 3 phases from the wind gen together, so it looks like the Wind MPPT has a 3 phase rectifier built into the input. I would use a contactor rated at 30A. You can then control this via relay switched by the relay output from the Cerbo - DON’T try to drive the contactor directly from the cerbo.
