1.GENERAL INFORMATION
1.1 OVERVIEW
XTRA series controller carry XDS2 display unit that 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 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.
Features
