The Enerdrive MPPT Solar Controllers adopt the advanced MPPT control algorithm, it can minimize the maximum power point loss rate and loss time, quickly track the maximum power point (MPP) of the PV array and obtain the maximum energy from solar array under any conditions; and it can increase the ratio of energy utilization in the solar system by 20%-30% compared with PWM charging method.

The Enerdrive MPPT Solar Controllers has self-adaptive three-stage charging mode based on digital control circuit, which can effectively prolong the lifespan of batteries and significantly improve the system performance. It also has comprehensive electronic protection for overcharge, over discharge, PV & battery reverse polarity. This controller can be widely used for RV, Marine, remote off grid monitoring and many other applications.

IP33 Ingress protection and isolated RS485 design further improves the controller’s reliability and meet the different application requirements.

1. When lithium battery is used, the system voltage can’t be identified automatically.
2. At minimum operating environment temperature.
3. At 25°C environment temperature.
4. When lithium battery is used, the temperature compensate coefficient must be 0, and can’t be changed.
5. The controller can supply full load working in the environment temperature. When the internal temperature reaches 81°C, the reduced charging power mode is turned on.
