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.

The unit is fully waterproof and is perfect for outdoor solar installations such as lighting systems. It is also great for vehicles and boats, particularly if installed in places affected by high humidity.

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 and has different charging parameters for different battery types (simpler controllers can only work with one battery type and average charging parameters). In addition, it can work with solar panels with input voltage up to 50V, so it's suitable not only for standard off-grid solar modules, but also with on-grid panels which have higher voltage (for maximum efficiency of charging 12V batteries by solar panels with output voltage higher than 25V please consider our MPPT solar charge controllers).

The controller can take input from solar panels up to 320W (with 12V batteries) / 640W (with 24V batteries), which makes it a perfect choice for small or medium solar PV systems with a battery and load such as in a motorhome, caravan, boat / yacht or other off-grid solar applications with batteries such as electric fencing or lighting.
