Features

• All solar panels (except the 5w and 10W) require a voltage regulator to ensure that the battery is not overcharged. We recomm*** (RS ; 905-4536 905-4536 ) controller for solar systems with a total watts of 100w to 300w We recomm*** (RS ; 905-4532 905-4532 ) controller for panels up to and including 150w. Solar Technology Dual Battery Charge Controller. This controller is for off-grid solar systems and has the additional functionality that it can charge two batteries simultaneouslyand can work on both 12v or 24v systems. The charging process has been optimized 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. 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 Charge current protection up to 10A (RS ; 905-4532 905-4532 ) Charge current protection up to 20A (RS ; 905-4536 905-4536 )
