XTRA Series MPPT Solar Charge Controller (20-40A) by Epever

Epever's XTRA Series MPPT Solar Charge Controller for off-grid PV systems with XDS2 LCD displays.

Using Epsolar technology to maximise energy harvest from PV arrays and simultaneously minimize the power loss within a wide range of operating conditions, the XTRA series applies an advanced smart algorithm that results in up to 30% higher efficient charging compared to a conventional pulse width modulation (PWM) charge controller. XTRA Series controllers have a limit protection function on charging current & charging power, as well as auto-derating power operation at high temperatures; this protection ensures the system's stability even at exceeded rated PV power and over-temperature conditions.  Protection class IP32 and isolated RS485 communication port further improve the controller’s reliability under different application requirements. XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which effectively prolongs the battery's lifespan and significantly improves the system's performance. It also has extensive electronic protection for overcharging, overdischarge, PV & battery reverse polarity, and more to ensure the sustainability
and durability of the off-grid solar system.

The XTRA Series controllers can be widely used for off-grid RV, household systems, field monitoring and many other applications.
