To charge two batteries from one solar panel, you need two solar charge controllers. My new PWM5 controller has been specifically designed to be used in this configuration. Both batteries are individually monitored and controlled to ensure optimum charge rate and voltage. This is a common configuration on boats. One battery is used to start the engine and the other is used for navigation electronics or TV/fridge.

Sorry for the end, some people don’t know how to shut up when one is filming. Showing the application of the silicone and the placement of the top panel of glass. 3 hours to set, then buy some trim and brackets! This video was uploaded from an Android phone.
