1. General Information
1.1 Overview
The XTRA-N series integrate the latest design philosophy, as the main part which is
the solar charge controller can carry different display units(XDB1/XDS1/XDS2). The
limitation function of the charging power and current and reducing charging power
function automatic improve the stability which works even connecting oversize PV
modules and in high temperature. Meanwhile, it adopts the water-proof design with
the IP32 class, and increase the professional protection chip for the communication
port, further improving the reliability and meeting the different application
requirements.
Improving the MPPT control algorithm further, XTRA N series can minimize the
maximum power point loss rate and loss time, quickly track the maximum power point
of the PV array and obtain the maximum energy from solar modules under any
conditions; and can increase the ratio of energy utilization in the solar system by
10%-30% compared with a PWM charging method.
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
damages 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. This modular solar controller can
be widely used for different applications, e.g., Communication base stations,
household systems, and field monitoring, etc.
