Specifications for MPPT Xtra-N Marine Series Controllers
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 manage Lithium ion and LiFePo4 batteries 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.
