I just discovered that the solar charge controller I bought for my camper van solar setup is positive ground. So I need some help.
First of all, someone explained it to me like a light switch. So normally, the negative wires are connected and the positive wires act as the switch, but with this charge controller it is like the positive wires are connected and the negative wires act as the switch.
But my problem comes with actual negative grounding of my solar setup.
This is my plan: I have wires going from my solar panels through a breaker which then goes into the charge controller. Then positive wire goes from charge controller to a fuse on the positive busbar. The positive battery is connected to the other side of that fuse. Connected to the battery side of the fuse is an on/off switch. Then there is a fuse on the other side of the on/of switch. The other side of that fuse is the positive wire from the inverter.
The negative wire goes from the charge controller to the negative busbar. The negative wire from the battery goes to this busbar, and the negative wire from the inverter goes to this busbar. I was going to ground this negative busbar to the chassis. The seller of the charge controller said that I should wire everything normally, but that the "controller, battery, busbars, and inverter should not be grounded".
So now I'm confused. I learned that I should not use the Load terminals of the charge controller and that is fine. But why should I not ground the negative busbar to the chassis. And if I don't ground it, how is my system ground? And I don't think I should ground the positive busbar to the chassis, right? I'm so confused, can someone please help?
