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 300W.
