General Information; Overview - Epever SolarV AN Series User Manual

1. General Information

1.1 Overview

Tracer AN series controller is based on common negative design and advanced MPPT control algorithm,
with LCD displaying running status, this product is artistic, economical and practical. The MPPT control
algorithm 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 20%-30% compared with a 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. and increase the professional protection chip for the
RS485 port, further improving the reliability and meeting the different application requirements.
Tracer AN 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 etc, to
ensure the solar system more reliable and more durable. This controller can be widely used for RV,
communication base station, household system, field monitoring and many other areas.
