The Goal Zero 20A Charger Controller is a controller that can be connected between a Goal Zero solar panel with an 8mm output and a 12V battery. The alternating voltage of the solar panel is converted into a constant voltage to charge the battery. The new charge controller from Goal Zero has a built-in LCD display, where you have a visual control over the charging process, the voltage, but also the temperature. In this way the system is easy to monitor.
Important: Additional accessories are required to use this charge controller. See the matching accessories.
