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

(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:

2.5 Mounting
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 turn off the breaker before wiring and
be careful when wiring.
Tracer-AN series controllers have no battery reverse protection. Do not
reverse the battery during the wiring. Otherwise, the controller may be
damaged.
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
When installing the controller, ensure enough air flowing through the controller's heat sink.
Please leave at least 150mm clearance away from the upper and lower edges.
Ventilation is highly recommended if mounted in an enclosure.
18
Step2: Remove the terminal protective cover.
Step 3: Connect the battery (Left) and PV (Right)
NOTE: Disconnect the system in the reverse order.
Tracer-AN series controllers have no battery reverse protection. Do not reverse
the battery during the wiring. Otherwise, the controller may be damaged.
During the wiring, please do not close the circuit breaker or fuse. Ensure that
the leads of "+" and "-" poles are polarity correctly.
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 to the controller's load
side.
19
Single controller
Connection in parallel
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
20
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 due to the electrification of the shell.
For common-negative systems, such as the RV system, it is recommended to use
a common-negative controller. If a common-positive controller is used and the
positive electrode is grounded in the common-negative system, the controller may
be damaged.
Step 5：Connect accessories
Connect the remote temperature sensor cable (Model: RTS300R47K3.81A)
Connect the remote temperature sensor cable to the interface ❽ and place
the other end close to the battery.
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 interface⓫ and 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
Close the battery's fuse to power on the controller. After the LCD normally displays, close
the PV array's circuit breaker. The charging indicator is slow flashing during the PV
charging process.
If the controller can not work properly or the fault indicator shows an abnormality,
please refer to4.2 "Troubleshooting."

4 Others
4.1 Protections
Tracer AN series controllers have no battery reverse protection. Do not reverse the
battery during the wiring. Otherwise, the controller may be damaged.
Protections
Instruction
PV
current/power-limiting
protection
When the PV array's actual charging current or power exceeds
the controller's rated charging current or power, the controller
charges the battery as per the rated current or power.
PV short-circuit
protection
When not in the PV charging state, the controller will not be
damaged in the case of short-circuiting in the PV array.
It is forbidden to short-circuit the PV array during charging. Otherwise,
the controller may be damaged.
PV reverse polarity
protection
When the PV array's polarity is reversed, the controller may not
be damaged and resume work after the mis-wiring is corrected.
If the PV array is reversed and its actual power is 1.5 times the
controller's rated power, the controller may be damaged.
Night reverse
charging protection
Prevent the battery from discharging to the PV module at night.
Battery over voltage
protection
When the battery voltage reaches the over voltage disconnect
voltage, the PV array will automatically stop charging the battery
to prevent the battery damage caused by over charging.
Battery over
discharging
protection
When the battery voltage reaches the low voltage disconnect
voltage, the battery discharging is automatically stopped to
prevent battery damage caused by over discharging.
When a load is connected to the battery, and the load is connected to
the controller's (Load) dry contact, the battery over-discharge
protection takes effect.
Battery over heating
protection
The controller detects the battery temperature through an
external temperature sensor. The battery stops working when its
temperature exceeds 65℃ and resumes work when its
temperature is below 55℃.
29
Lithium battery low
temperature
protection
When the temperature detected by the optional temperature
sensor is lower than the Low Temperature Protection
Threshold(LTPT), the controller stops charging and discharging
automatically. When the detected temperature is higher than the
LTPT, the controller resumes work automatically. (The LTPT is
0 °C by default and can be set within the range of 10 ~ -40 °C.
Detail settings refer to the LTPT V1.0.)
Controller
Overheating★
An internal temperature sensor can detect the internal
temperature of the controller. The controller stops working when
the internal temperature exceeds 85℃ and resumes work when
the internal temperature is below 75℃.
TVS high voltage
transients protection
The controller's internal circuitry is designed with Transient
Voltage Suppressors (TVS), which can only protect against
high-voltage surge pulses with less energy. Suppose the
controller is to be used in an area with frequent lightning strikes.
In that case, it is recommended to install an external surge
arrester.
★ When the control's internal temperature is 81℃, the reducing power charging mode is
turned on, reducing the charging power of 5%,10%,20%,40% every increase of 1 ℃. If the
internal temperature is greater than 85℃, the controller stops charging. When the internal
temperature is not more than 75ºC, the controller will resume charge as per the rated power.

4.3 Maintenance
The following inspections and maintenance tasks are recommended at least two times per
year for the best performance.
Make sure no block on airflow around the controller. Clear up any dirt and fragments on
the radiator.
Check all the naked wires to ensure insulation is not damaged for sun exposure,
frictional wear, dryness, insects or rats, etc. Repair or replace some wires if necessary.
Check and confirm that LED is consistent with required. Pay attention to any
troubleshooting or error indication. Take necessary corrective action.
Confirm that all terminals have no corrosion, insulation damaged, high temperature, or
burnt/discolored sign, and tighten terminal screws to the suggested torque.
31
Clear up dirt, nesting insects, and corrosion in time.
Check and confirm that the lightning arrester is in good condition. Replace a new one
in time to avoid damaging the controller and even other equipment.
Risk of electric shock!
Ensure that all the power is turned off before the above operations, and then follow
the corresponding inspections and operations.
