Charge controller for off-grid solar systems with the additional functionality that it can charge two batteries simultaneously. Works on both 12v and 24v systems.

The charging process optimizes long battery life and improves 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
Deep discharge protection
Charge current protection up to 20A

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
