This high quality waterproof 20A 12V/24V solar charge controller is designed to protect batteries whilst charging them, with a full range of automatic protection features. The controller uses high efficiency MPPT charging technology to get the most possible power out of your solar panels.

This controller stops reverse current (from the battery back to the solar panel) so your battery won't lose any charge at night and can be left permanently connected. It has many other protection functions such as over charge / discharge shut-off, over load and short circuit protection for the load terminals, overheating protection for the battery and more.

This controller can work with a range of 12V or 24V battery types, including liquid, Gel, AGM, and Lithium. With a wide range of solar input voltages (up to 55V) this controller can work not only with standard off-grid solar modules, but also with on-grid panels which have higher voltage. The controller can accept up to 260W (in a 12V system) or 520W (in a 24V system) of solar panels which makes it a perfect choice for small or medium solar PV systems with a battery and load such as in a camper van or boat.

In addition, the solar charge controller is completely sealed with a very high degree of water protection. It is absolutely safe to use this solar controller in all weather conditions.

This controller has Bluetooth communication function, the Bluetooth module of the controller can be connected to a mobile phone after installing the App. The App can view the real-time working status of the controller and adjust settings, including device and battery parameters.
