I have just purchased several Victron components for my truck camper, one of which is a Victron MultiPlus 12/3000/120. It is paired with 2x206ahr SOK Lithium batteries. I have spent several days diagnosing a problem I am having and concluded the source is the inverter. It’s a very long story how I got here, but suffice it to say, when I remove the fuse on the Lynx Distribution bar for the Multiplus, the problem goes away. My problem is this.
I have expected voltage on the input side of the Blue Sea battery disconnect switch and nothing on the output side of the switch. When I first turn on the battery disconnect switch, I get a click in the Multiplus, then it shuts down. The result is readings (using a multi meter) of approximately 2 volts throughout the entire system, INCLUDING at the battery terminals and all the way down the system. When I shut the switch off and immediately back on, and all is well in the land. All my 120v and 12v devices work as expected. My 120v plugs test Good. I’ve even run the Air Conditioner off the system and also hooked it to shore power (15 Amp) and bulk charged the batteries for a short while. If I wait a short period of time (e.g. a few minutes) and turn the switch back on……just a click and 2 volts in the system. A quick Off and On of the switch, and all is well again. Any help would be appreciated.
