Solar Technology 10A Dual Battery Charge Controller

This 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. We recommend the this controller for panels up to and including 150W
