Hi
I have a multiplus compact 12volt / 1600s / 70 amp
The unit less than 7 months old since installed in new RV.
Everything has been fine then suddenly we notice that the unit is switching to inverter and back again to power, sometimes 5-6 times per min. The 2-3 times a min. It only stays on inverter for a few seconds then back to power.
Hi @MartinCole. That could be normal behaviour, but depends on how it’s set up. Do you have a Venus or Color Control connected to it? This will enable you to see why the unit is doing that. A big possibility is that the input voltage moves outside of the specified input voltage parameters, and then the multi would switch to inverter mode. If you don’t have a Venus or Color Control, use a multimeter to monitor the input voltage on the AC in terminals and see what happens.
Thanks. The guy next door just turned off his Air con to his RV and everything returned to normal. I suspect like you say fluctuating voltage going below the threshold.
