Solar, Battery and Pump

The rooftop garden also includes a solar panel that is used to charge a 12V RV battery that provides power to a 12V RV pump. The wiring diagram can be seen below. Do NOT connect the AC inverter through the charge controller, and make sure to only connect low power devices (i.e. light bulb, phone charger).
