This high quality waterproof 20A 12V/24V solar charge controller is designed to protect batteries whilst charging them, having automatic cut off to prevent over-charging and deep discharge. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your battery. Often PWM technology can recover some lost battery capacity.

This controller stops reverse current at night (from the battery back to the solar panel) so your battery won't lose any charge. It has many other protection functions such as over charge / discharge, over load, short circuit, overheating etc. Other features of this controller include LED indicators, temperature sensor, battery type selection, dual timer function and several load work modes.

This controller can work with sealed, gel and flooded batteries (simpler controllers can only work with one battery type). In addition, it can accept a wide range of solar input voltage up to 50V, so 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 handle up to 320W (with 12V batteries) / 640W (with 24V batteries) 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 has a very high degree of water protection - IP67 (which means it's completely sealed), so it is absolutely safe to use this solar kit in all weather conditions.

Further to the built-in temperature sensor there is an external temperature sensor located on the controller to measure the ambient temperature more precisely and optimise the charging process.
