1 General Information

1.1 Overview

Based on multiphase synchronous rectification technology(MSRT) and advanced MPPT
control algorithm, adopt dual-core processor and co-negative design, Tracer-AN series
controllers own the fast response characteristics, high reliability, and industrial standards.
MSRT guarantees a high conversion efficiency in any charging power, which sharply
improves the solar system's energy efficiency. The new optimized MPPT tracking
technology can fast track the PV array's max power point in any situation and obtains the
maximum energy in real-time.
The automatic power reduction function fully ensures access to excess PV modules and
high temperature running.
The Tracer-AN series controller owns a self-adaptive three-stage charging mode based on
a digital control circuit. This function can effectively prolong the battery's lifespan and
significantly improve the system's performance.
The load/utility/generator dry contact to connect external devices conveniently composes a
hybrid power system easily.
Comprehensive electronic protections, including overcharging, over-discharging, and PV
reverse polarity protection, effectively ensure the more reliable and durable solar system
operation for a longer running time.
The isolated RS485 port with standard MODBUS communication protocol and 5V power
supply is easy to expand the application. Up to 6 controllers connected in parallel is
supported. The controller can be widely used for various applications, e.g., solar RV,
household system and field monitoring, etc.
