This PMW controller is for off-grid solar systems and has the additional functionality that it can charge two batteries simultaneously and can work on both 12v or 24v systems.

The charging process has been optimised for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.

All solar panels (except the 5w &10w) require a voltage regulator to ensure that the battery is not overcharged (this is the regulator).

We recommend this controller for solar systems with a total watts of 100w to 300w.

Reverse current protection. Unique dual battery charging function. Efficient Series PWM charging, increases battery lifetime and improves solar system performance. 12/24V automatic recognition. Overload protection Open circuit protection Lightning surge protection Deep discharge protection Charge current protection up to 20A (This setting is only required for advanced applications when there are some radio emitting devices powered by the same batteries and where the solar controller creates interference in the circuit. In such cases the charging frequency can be changed to stop interference. In all other cases this parameter should be kept at pre-set 25Hz. Change of charging frequency has almost no impact on the efficiency of charging.)
