I just purchased a Renogy Rover PG Series PG 20A Charge Controller and a 100 watt 18.9 volt solar panel. I bought them to install on my motorhome. In the past I have installed solar panels on RV's, but this is the first MPPT charge controller that I have had. My first concern is that it says that this controller is a Positive Ground. The motorhome is a negative ground. Will it work? My next concern is the Load Terminals. I don't understand what they are for. I just want to charge my Motorhome coach battery. Do I need to send this controller back and get a different one? Is the 18.9 volt solar panel enough voltage for this thing to work. I wish that I had just stayed with a traditional Charge controller. They are much easier to deal with.

WOW, hard to believe that it is a Positive Ground. Please provide page of the manual. Yes sir I agree....
Snakebite What page did you read that on?
Yes that system should keep your batteries charged as long as you don't have to large of a draw...
Also don't worry about the load side it's for small things like 12v lights and such....

The Rover 20A PG is an amazon exclusive charge controller. The load terminals are for simple DC appliances but better optimized for lights. The controller being positive ground simply means that if you need to ground the controller, it would need to be on the positive terminal of the controller. Most controllers on RV's tend to float, as in they're not grounded to the earth. You might experience load shorting problems if any of your loads connected directly to the controller are negatively grounded to the chassis. To bypass this, you would need to connect loads directly to your battery bank.
