Grounding a solar charge controller
I am interested in the Renogy Solar30 controller, but the web site has this statement:
Please Note:This is Positive Ground Controller. If grounding is necessary, it must be completed on the positive line. If the controller is to be used on a vehicle which has battery negative on the chassis, loads connected to the controller must not have an electrical connection to the vehicle body.
If you want to connect the solar system to a negative ground battery bank, you can choose ViewStar Charge Controller or MPPT Charge Controller.
Does the controller need to be grounded? At least initially, I am planning on using this with a portable 100W panel. I don't plan on connecting any loads directly.
The ViewStar controller is almost twice the price. I do want a controller that displays amps and amp-hours.
