1 General Information
1.1 Overview
XTRA N series controller which can carry different display units(XDB1/XDS1/XDS2) adopt 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 ratio 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
RS485 design further
improve the controller’s reliability and meet the different application
requirements.
XTRA N series 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, overdischarge, 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 many other
applications.
