The solar charge controller adopts 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 ration of energy utilization in the solar system by 20% - 30% compared with PWM charging method.

Limiting the charging power & current and reducing charging power functions ensure the system stable with over PV modules in high temperature environment. IP33 ingress protection and isolated PS485 design further improve the controller’s reliability and meet the different application requirements.  

The controller owns self-adaptive three-stage charging mode based on digital control circuit, which can effectively prolong the lifespan of battery and significantly improve the system performance. It also has comprehensive electronic protection for overcharge, over discharge, PV & battery reverse polarity etc., to ensure the solar system more reliable and more durable. This controller can be widely used for RV, household system, field monitoring and may other applications.
