10A PWM Dual Battery Charge Controller

The Merlin SolarPlex PWM Controller is designed specifically for off-grid solar systems, offering advanced features such as the ability to simultaneously charge two batteries and compatibility with both 12V and 24V systems.

The charging process has been optimised to extend battery life and enhance overall system performance. With comprehensive self-diagnostics and electronic protection functions, this controller serves as a reliable safeguard against potential damage caused by installation errors or system faults.

For optimal performance, it is essential to use a voltage regulator with all solar panels (excluding the 5W and 10W models), to prevent overcharging of the battery. We recommend the 10A PWM controller for panels up to and including 150W, and the 20A PWM Controller for panels up to and including 300W.
