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

2 Installation
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 result in 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
(1) 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) Max. PV Array Power
This MPPT controller has the function of charging current/power-limiting. During the
charging process, when the actual charging current or charging power exceeds the rated
charging current or charging power, the controller automatically limits the current or power.
It charges the battery as per the rated charging current or charging power. This function
can effectively protect the controller's charging modules and prevent damage to the
controller due to the over-connected PV array. The actual running status of the PV array is
as follows:
Condition 1: Actual PV array's charging power ≤ Rated controller's charging power
Condition 2: Actual PV array's charging current ≤ Rated controller's charging current
When the controller works under "Condition 1" or "Condition 2," it charges the battery as
per the actual charging current or actual charging power. At this time, the controller can
work at the maximum power point of the PV array.
When the PV module's power is not greater than the rated charging power, the PV
array's maximum open-circuit voltage is more than
100V(Tracer**10AN)/150V(Tracer**15AN)/200V(Tracer**20AN) at the lowest
temperature, the controller is damaged.
Condition 3: Actual PV array's charging power >Rated controller's charging power
Condition 4: Actual PV array's charging current >Rated controller's charging current
When the controller operates under "Condition 3" or "Condition 4," it will carry out the
charging as per the rated current or power.
When the PV module's power is greater than the rated charging power, the PV
array's maximum open-circuit voltage is more than
100V(Tracer**10AN)/150V(Tracer**15AN)/200V(Tracer**20AN) at the lowest
temperature), the controller is damaged.
According to the "Peak Sun Hours diagram," if the PV array's power exceeds the
controller's rated charging power, the charging time as per the rated power is prolonged.
The controller can obtain more energy. However, in the practical application, the PV array's
maximum power shall be not higher than 1.5 times the controller's rated charging power.
Suppose the PV array's maximum power exceeds the controller's rated charging power too

13
much. In that case, it may cause the PV array's waste and increase the PV array's
open-circuit voltage due to the environmental temperature. It may increase the damage
probability to the controller. For the recommended maximum power of the PV array, please
refer to the table below:

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 its size, connection method, and sunlight angle.
The minimum wire size can be calculated by its ISC(short circuit current). Please refer to
the ISC value in the PV module's specifications. When the PV modules are connected in
series, the total ISC is equal to any PV module's ISC. When the PV modules are connected
in parallel, the total ISC is equal to 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 as below:
