1 General Information

1.1 Overview

Tracer AN series controller, based on multiphase synchronous rectification technology (MSRT) and
advanced MPPT control algorithm, with dual-core processor architecture and common negative design,
has the features of high response speed, high reliability, and high industrial standard. MSRT can
guarantee very high conversion efficiency in any charge power, which sharply improves the energy
efficiency of solar system; Advanced MPPT control algorithm minimize the maximum power point loss
rate and loss time, to ensure the tracking efficiency, corresponding speed as well as high conversion
efficiency under high or low power, so that in any situation, Tracer AN products can rapidly track the
maximum power point(MPP) of PV array to obtain the maximum energy of the panel. The limitation
function of the charging power and current, and automatic power reduction function fully ensure the
stability when works with oversize PV modules and operate under high temperature environment.
With the adaptive three-stage charging mode based on digital control circuit, Tracer AN series
controllers can effectively prolong the life-cycle of battery and significantly improve the system
performance. The load, utility or generator auto-control relays make it easy to compose the hybrid
power system. All-around electronic protections, including overcharging, over discharging, and PV
reverse polarity protection, effectively ensure the safer and more reliable operation of the solar
system for a longer service time. The isolated RS485 interface with standard MODBUS communication
protocol and 5V power supply makes it easy for customer to expand the application, it support up to 6
charging in parallel to expand system and meet with different monitoring requirements, so that can be
widely used for various applications, e.g. solar RV, household system and field monitoring, etc.
