2 Installation
2.1 General Installation Notes
Before installation, please read through the entire installation instructions to get familiar with the
installation steps.
Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear eye
protection, and have fresh water available to wash and clean if any contact with battery acid.
Keep the battery away from any metal objects, which may cause short circuit of the battery.
Explosive battery gases may come out from the battery during charging, so make sure ventilation
condition is good.
The controller can work with lead-acid battery and lithium battery within its control scope.
Ventilation is highly recommended if mounted in an enclosure. Never install the controller in a
sealed enclosure with flooded batteries! Battery fumes from vented batteries will corrode and
destroy the controller circuits.
Loose power connections and corroded wires may result in high heat that can melt wire insulation,
burning surrounding materials, or even causing fire. Ensure tight connections and use cable clamps
to secure cables and prevent them from swaying in mobile applications.
Battery connection may be wired to one battery or a bank of batteries. The following instructions
refer to a singular battery, but it is implied that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
Multiple same models of controllers can be installed in parallel on the same battery bank to achieve
higher charging current. Each controller must have its own solar module(s).
Select the system cables according to 5A/mm2or less current density in accordance with Article 690
of the National Electrical Code, NFPA 70.
2.2 PV Array Requirements
(1)Serial connection (string) of PV modules
As the core component of PV system, Controller could be suitable for various types of PV modules and
maximize converting solar energy into electrical energy. According to the open circuit voltage (Voc) and

(2) PV array maximum power
The MPPT controller has the function of current/power-limiting, that is, during the charging process,
when the charging current or power exceeds the rated charging current or power, the controller will
automatically limit the charging current or power to the rated charging current or power, which can
effectively protect the charging parts of controller, and prevent damages to the controller due to the

7

www.solarv.de
connection of some over-specification PV modules. The actual operation of PV array is as follows:
Condition 1:
Actual charging power of PV array ≤ Rated charging power of controller
Condition 2:
Actual charging current of PV array ≤ Rated charging current of controller
When the controller operates under “Condition 1”or“Condition 2”, it will carry out the charging as
per the actual current or power; at this time, the controller can work at the maximum power point of
PV array.
WARNING: When the power of PV module is greater than the rated charging power, and the
maximum open-circuit voltage of PV array is more than
100V(Tracer**10AN)/150V(Tracer**15AN)/200V(Tracer**20N) (at the lowest environmental
temperature), the controller may be damaged.
Condition 3:
Actual charging power of PV array＞Rated charging power of controller
Condition 4:
Actual charging current of PV array＞Rated charging current of controller
When the controller operates under “Condition 3”or“Condition 4”，it will carry out the charging as
per the rated current or power.
WARNING: When the power of PV module is greater than the rated charging power, and the
maximum open-circuit voltage of PV array is more than
100V(Tracer**10AN)/150V(Tracer**15AN)/200V(Tracer**20N) (at the lowest environmental
temperature), the controller may be damaged.
According to “Peak Sun Hours diagram”, if the power of PV array exceeds the rated charging power of
controller, then the charging time as per the rated power will be prolonged, so that more energy can
be obtained for charging the battery. However, in the practical application, the maximum power of PV
array shall not be greater than 1.5 x the rated charging power of controller. If the maximum power of
PV array exceeds the rated charging power of controller too much, it will not only cause the waste of
PV modules, but also increase the open-circuit voltage of PV array due to the influence of
environmental temperature, which may increase the probability of damage to the controller rise.
Therefore, it is very important to configure the system reasonably. For the recommended maximum
power of PV array for this controller, please refer to the table below:

2.3 Wire Size
The wiring and installation methods must conform to all national and local electrical code
requirements.
PV Wire Size
Since PV array output can vary due to the PV module size, connection method or sunlight angle, the
minimum wire size can be calculated by the Isc＊of PV array. Please refer to the value of Isc in the PV
module specification. When PV modules connect in series, the Isc is equal to a PV modules Isc. When
PV modules connect in parallel, the Isc is equal to the sum of the PV module’s Isc. The Isc of the PV
array must not exceed the controller’s maximum PV input current. Please refer to the table as below:
NOTE: All PV modules in a given array are assumed to be identical.

Step 4：Grounding
Tracer AN series is a common-negative controller, if any of one negative is grounded, all the negative
terminals of PV, Battery will be grounded simultaneously. However, according to the practical
application, all the negative terminals of PV array, battery and load can also be ungrounded, but the
grounding terminal on its shell must be grounded, which may effectively shield the electromagnetic
interference from the outside, and prevent some electric shock to human body due to the
electrification of the shell.
CAUTION: For common-negative system, such as motorhome, it is recommended to use a
common-negative controller; but if in the common-negative system, some common-positive
equipment are used, and the positive electrode is grounded, 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 ❽and place
the other end close to the battery.
CAUTION: If the remote temperature sensor is not connected to the controller,, the default
setting for battery charging or discharging temperature is 25 °C without temperature compensation.
Connect Remote Battery Voltage Sensor (Model:RVBS300B3.81)
Connect the remote battery voltage sensor cable to the interface ⓫and connect the other end to the
battery terminals.
Connect the accessories for RS485 communication, refer to the accessories list.
Step 6：Powered on the controller
Turn on the battery fuse to power on the controller, then check the LCD is OFF or the fault indictor is
ON when the controller is normal.
CAUTION: If the controller is not operating properly or the battery indicator on the controller
