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. IP32
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.
