I’ve searched for an answer to this but not found anything that specifically adresses it.
I was told that I can use my Cerbo GX relay to turn my Xantrex Freedom XC inverter on/off in the event of a power failure so the small heaters I have running on the boat in the winter don’t kill the batteries. According to the Inverter manual, there is only one wire (the ignition control wire) that connects to the Inverter ACC input, but I’m unsure which of the three relay connections on the Cerbo GX Relay 2 block (NO/NC/COM) to connect this one wire to. It would be normally open (inverter running) and I would trigger the relay to close it (thereby turning off the inverter because there is no ignition signal present) if I see the battery voltage drop below a threshold, and turn it back on when the power comes back on. So two questions:
- is this do-able
- which connection do I use … the NO?
Thanks
