I have just installed a Multiplus 12/1600/70 into my campervan. I have two 120ah L:ithium batteries. As I don't currently have a pc or laptop I just did the dip switch install and I'm not convinced its set up right. The inverter side is working fine. But the charging side I'm not too sure. The first time I tried it the batteries were about 90% full the charger kicked straight in. The fans sparked up. It charged for about five or ten minutes then the alarm light came on with the fans still running.
So I have run the batteries down and then tried charging again. This was a little more successful but as the batteries got full I was off to bed and didn't want to leave it turned on.
So the question is would I be better not using the charging side until I can set it up with the software as I am getting and Ipad pro. Will this be ok to use?? I hope this makes sense? It's the first time on the forum. Cheers.
