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.
All solar panels (except the 5w &10W) require a voltage regulator to ensure that the battery is not overcharged. We recommend this controller for solar systems with a total watts of 100w to 300w
