1 General Information
1.1 Overview
The Tracer-AN controllers, based on the multiphase synchronous rectification technology(MSRT) and
advanced MPPT control algorithm, adopt a dual-core processor and co-negative design. This help
features the controllers with 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 obtain 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 a 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 are 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
Program temperature compensation for batteries.
Real-time energy statistics function

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 detect the battery temperature remotely. The
sampling distance is no longer than 20m.
CAUTION
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 RS485 port 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. When the lithium battery and inverter are used
together in the system, connect the controller's (Load) dry contact to the inverter's start-stop dry
contact. The controller will manage the inverter's start or stop. If the lithium battery fails, It can
protect the controller from being damaged because of the over-current by preventing the controller
from directly starting the inverter.
(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.

2.1 Attentions
Be very careful when installing the batteries. Please wear eye protection when installing the open-type
lead-acid battery and rinse with clean water in time for battery acid contact.
Keep the battery away from any metal objects, which may cause a battery short circuit.
Acid gas may be generated when the battery is charged. Ensure that the surrounding environment is
well ventilated.
Avoid direct sunlight and rain infiltration when installing it outdoor.
Loose power connections and corroded wires may produce high heat that can melt wire insulation,
burn surrounding materials, or even cause a fire. Ensure tight connections and secure cables with
clamps to prevent them from swaying while moving the inverter.
Only charge the lead-acid and lithium-ion batteries within the control range of this controller.
The battery connector may be wired to another battery or a bank of batteries. The following instructions
refer to a singular battery. Still, it is implied that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
Select the system cables according to 5A/mm2or less current density.
2.2 Requirements for the PV array
Serial connection (string) of PV modules
As the core component of the solar system, the controller needs to suit various PV modules and
maximize solar energy conversion into electricity.According to the open-circuit voltage (VOC) and the
maximum power point voltage (VMPP) of the MPPT controller, the serial connection of PV modules
suitable for different controllers can be calculated. The below table is for reference only.

2.3 Wire size
The wiring and installation methods must conform to the national and local electrical code requirements.
PV wire size
The PV array's output current varies with size, connection method, and sunlight angle. Its ISC (short
circuit current) can calculate the minimum wire size. Please refer to the ISC value in the PV module's
specifications. When the PV modules are connected in series, the total ISC equals any PV module's ISC.
When the PV modules are connected in parallel, the total ISC equals the sum of all the PV module's ISC.
The PV array's ISC must not exceed the controller's maximum PV input current. For max. PV input
current and max. PV wire size, please refer to the table below:

2.5 Mounting
WARNING
Risk of explosion! Never install the controller in a sealed enclose with flooded
batteries! Do not install the controller in a confined area where battery gas can
accumulate.
Risk of electric shock! When wiring the solar modules, the PV array can produce a
high open-circuit voltage, so disconnect the breaker before wiring and be careful.
Tracer-AN series controllers have no battery reverse protection. Do not reverse
the battery during the wiring. Otherwise, the controller may be damaged.
CAUTION
The controller requires at least 150mm of clearance above and below for proper
airflow. Ventilation is highly recommended if mounted in an enclosure.
Installation procedures:
Step 1: Determine the installation location and heat-dissipation space
Ensure enough air flows through the controller's heat sink when installing the controller. Please leave at
least 150mm clearance away from the upper and lower edges.

10
CAUTION
Ventilation is highly recommended if mounted in an enclosure.
Step2: Remove the terminal protective cover.
Step 3: Connect the battery(Left) and PV(Right)
IMPORTANT
Disconnect the system in reverse order.
WARNING
Tracer-AN series controllers have no battery reverse protection. Do not reverse the
battery during the wiring. Otherwise, the controller may be damaged.
CAUTION
During the wiring, please do not connect the circuit breaker or fuse. Ensure that
the electrode polarity is correctly connected.
A fuse whose current is 1.25 to 2 times the controller's rated current must be
installed on the battery side with a distance from the battery no longer than 150
mm.
Please connect the inverter directly to the battery, not the controller's load side.
When the lithium battery and the inverter are used together, connect the

Step 4：Grounding
Tracer-AN series are common-negative controllers. Negative terminals of the PV array, the battery can
be grounded simultaneously, or any terminal is grounded. However, according to the practical application,
the PV array's negative terminals, battery, and load can also be ungrounded. Simultaneously, the
grounding terminal on the shell must be grounded, which effectively shields the electromagnetic
interference from the outside and prevents some electric shock to the human body.
CAUTION
It is recommended to use a common-negative controller for common-negative
systems, such as the RV system. The controller may be damaged if a
common-positive controller is used and the positive electrode is grounded in the
common-negative system.
Step 5：Connect accessories
Connect the remote temperature sensor cable (Model: RTS300R47K3.81A)
Connect the remote temperature sensor cable to the interface ❽and place the other end
close to the battery.
CAUTION
Suppose the remote temperature sensor is not connected to the controller. In that
case, the controller can charge or discharge the battery at the default 25 ºC(no
temperature compensation).
Connect the remote battery voltage sensor cable (Model: RVBS300B3.81)
Connect the remote battery voltage sensor cable to the interface⓫and connect the other end to the
battery terminals.
Connect the accessories for RS485 communication; refer to the accessories list.
Step 6：Power on the controller
Connect the battery fuse to power the controller.After the LCD normally displays, connect the PV array's
