1. General Information
1.1 Overview
The Tracer AN series. Based on common negative design and advanced MPPT
control algorithm, with LCD displaying running status, this product is artistic,
economical and practical. Improving the MPPT control algorithm further, Tracer AN
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. 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, and increase the professional protection chip for the
communication port, further improving the reliability and meeting the different
application requirements.
With the adaptive three-stage charging mode based on a digital control circuit, Tracer
AN 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.
