The Xtra-N marine series controllers are EP Solar’s second generation of MPPT controllers. They have rapid MPP (Maximum Power Point) calculation capability to achieve the maximum output of a solar array.  At 99.5% efficiency they are one of the most energy efficient controllers available which means they will convert the maximum amount of solar energy to battery charging power.

With the adaptive three-stage charging mode based on a digital control circuit, XTRA-N series controllers can effectively prolong the life-cycle of batteries, significantly improve the system performance and support all-around electronic protection functions, including overcharging and over discharging protection to minimize damage to components of the system caused by incorrect installation or system failure at the utmost, and effectively ensure safer and more reliable operation of the solar power supply system for a longer service time.

The Xtra-N series controllers include a built in display providing the same information as the MT50 remote display although the MT50 is an optional accessory.  The Xtra-N is designed to manageLithium ion and LiFePo4batteries as well as the standard flooded, AGM and sealed batteries.  The Xtra-N can be programmed from the built in display, the MT50 remote meter, a Bluetooth smart phone app or a computer connected via special cable.
