Important Safety Instructions

Please reserve this manual for future review.

This manual contains all safety, installation, and operation instructions for the Tracer-AN

series MPPT solar controller ("controller" referred to in this manual).

Read all the instructions and warnings carefully in the manual before installation.

No user-serviceable components inside the controller; please do not disassemble or

attempt to repair the controller.

Mount the controller indoors. Avoid exposure to the components and do not allow

water to enter the controller.

Install the controller in a well-ventilated place; the controller's heat sink may become

very hot during operation.

It is suggested to install appropriate external fuses/breakers.

Make sure to switch off all PV array connections and the battery fuse/breakers before

controller installation and adjustment.

Power connections must remain tight to avoid excessive heating from a loose

connection.

Explanation of symbols

To enable users to use the product efficiently and ensure personal and property safety,

please read related literature accompanying the following symbols.

Please read the literature accompanying the following symbols.

Tips: Indicate recommendations that can be referred to.

IMPORTANT: Indicates a critical tip during the operation, if ignored, may cause the

device to run in error.

CAUTION: Indicates potential hazards, if not avoided, may cause the device

damaged.

WARNING: Indicates the danger of electric shock; if not avoided, it would cause

casualties.

WARNING HOT SURFACE: Indicates the risk of high temperature, if not avoided,

would cause scalds.

All of the safety and operating instructions should be read, adhered to, and followed

before operating the device.

The entire system should be installed by professional and technical personnel.

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.

Features:

Comply with IEC62109-1 and EN61000-6-1/3 standard certification

High quality and low failure rate components of ST or IR to ensure the service life

High tracking efficiency of MPPT no less than 99.5%.

Maximum DC/DC transfer efficiency is as high as 98.6%★; full load efficiency is up to

98 %★

Accurate recognizing and tracking technology of multi-peaks maximum power point

Wider MPP running voltage to increase the PV modules' utilization ratio

Support the lead-acid and lithium batteries

Programmable temperature compensation feature for batteries.

Real-time energy statistics function

High temperature charging automatic power reduction function

100% charging and discharging in the working environment temperature range

Up to 6 controllers connection in parallel to expand the system

Load dry contact to control the external load switch

To set the first and the second disconnection voltage of load by the software

Auto-control of utility and generator dry contact design to compose a hybrid power

system easily

Remote temperature and voltage sensor design to collect more accurate battery

temperature/terminal voltage and eliminate the battery cables' voltage drop

Isolated RS485 communication ports (Modbus protocol)

5V/200mA RS485 communication ports with short circuit protection

Support remote monitoring and parameters setting via the APP or PC software

★The parameters are measured in the Tracer10415AN@48V system.

⓲Fault indicator

(1) Set the (Generator/Load) dry contact enable switch to ON,

the (Load) dry contact is enabled; while it is disabled when the switch is set to OFF.

(2) Connect an RTS (Remote Temperature Sensor) to remotely detect the battery

temperature. The sampling distance is no longer than 20m.

Suppose the temperature sensor is a short circuit or damaged. In that case, the

controller can charge or discharge the battery at the default temperature setting of

25 ºC(no temperature compensation).

(3) When connecting the controller to external devices, only one of the RS485 ports can

be used; when connecting multiple controllers in parallel, RS485 ports are for

cascaded use.

(4) Connect an RBVS (Remote Battery Voltage Sensor) to detect accurate battery voltage.

The sampling distance is no longer than 20m.

(5) Low Voltage Disconnect Voltage(VLVD) disconnects the dry contact.

Low Voltage Reconnect Voltage(VLVR) makes the dry contact connect.

(6) The controller is designed with a common negative polarity. The negative polarity of

the PV and the battery is located on the same busbar.
