1. General Information
1.1 Overview
The TRIRON N series controllers are modular-designed products based on six MPPT
solar controller models. The main unit(Power Module)(TRIRON-N) is a solar controller
which can be integrated with different display and interface modules to meet a
variety of functional requirements. The TRIRON N series controllers can automatically
identify and load the drivers of various modules. There are three display modules
(Basic 1(DB1), Standard1(DS1) and Stardard2(DS2)) and four interface modules
(USB COM Slave(UCS), Relay COM Slave(RCS), Relay COM Master(RCM) and
Dual USB1(USB1)). Users can choose any combination of these modules according
to their needs.
With the advanced MPPT control algorithm, TRIRON N series controllers can
minimize the maximum power point loss rate and loss time, quickly track the
maximum power point of the PV array and obtain the maximum energy from solar
modules under any conditions; and can increase the ratio of energy utilization in the
solar system by 20%-30% compared with a PWM charging method. With the adaptive
three-stage charging mode based on a digital control circuit, TRIRON N series
controllers can effectively prolong the lifecycle of batteries, significantly improve the
system performance and support all-around electronic protection functions, including
overcharging and over-discharging protection to minimize damages to components of
the system caused by incorrect installation or system failure at the utmost, and
effectively ensure safer and more reliable operation of the solar power supply system
for a longer service time. This modular solar controller can be widely used for different
applications, e.g., communication base stations, household systems, street lighting
systems and field monitoring, etc.

2. Installation Instructions
2.1 General Installation Notes
Please read the entire installation instructions to get familiar with the installation
steps before installation.
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 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.
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, burn surrounding materials, or even cause fire. Ensure tight
connections and use cable clamps to secure cables and prevent them from swaying
in mobile applications.
Lead-acid battery and lithium battery are recommended, other kinds please refer to
the battery manufacturer.
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 the maximum power point voltage (VMpp) of the
MPPT controller, the series number of different types PV modules can be calculated.

(2) Maximum PV array power
This MPPT controller has a limiting function of charging current/power. The charging
current/power will be limited within the rated range, therefore, the controller will
charge the battery with the rated charging power even if the input power at the PV
exceeds this limit.
The actual operation power of the PV array conforms to the conditions below:
1) PV array actual power ≤ controller rated charge power, the controller will charge
the battery at the actual maximum power point.
2) PV array actual power > controller rated charge power, the controller will charge
the battery at the charger’s maximum rated power.
If the PV power is higher than the charger’s maximum rated power, the charging time
at rated power to the battery will be longer, and more energy to battery will be stored
in the battery..
WARNING:
The controller has a maximum PV power input rating(watts), and will allow
the PV power to be higher than the rated power, but if the PV power is three
times greater than the rated power, the controller will damaged.
WARNING:
If the PV array is reverse connected to the controller,1.5 times rated
power(watts) will damage the controller.
When sizing a PV array to a charge controller, be sure to choose PV panels that when
combined(or singly),will not exceed the controller’s maximum inpt current rating(Isc)
and open circuit voltage rating(Voc), in addition to the power limitation noted above!

WARNING: The controller may be damaged when the maximum PV open
circuit voltage(Voc) exceeds 60V(TRIRON**06N), 100V(TRIRON**10N) or
150V (TRIRON**15N) at minimum operating environment temperature.
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.
＊Isc=short circuit current(amps) Voc=open circuit voltage.

or 92V (TRIRON**15N) at 25℃environment temperature.

NOTE: The wire size is only for reference. If there is a long distance
between the PV array and the controller or between the controller and the
battery, larger wires can be used to reduce the voltage drop and improve
performance.
2.4 Mounting
WARNING: Risk of explosion! Never install the controller in a sealed
enclose with flooded batteries! Do not install in a confined area where
battery gas can accumulate.
WARNING: Risk of electric shock! When wiring the solarmodules, the PV
array can produce open circuit voltages in excess of 100V when in
sunlight.
NOTE：The controller requires at least 150mm of clearance above and
below for proper air flow. Ventilation is highly recommended if mounted in
an enclosure.
Installation Procedure:
Figure2-1 Mounting

14
Step 1: Determination of Installation Location and Heat-dissipation Space
Determination of installation location: The controller shall be installed in a place with
sufficient air flow through the radiators of the controller and a minimum clearance of
150 mm from the upper and lower edges of the controller to ensure natural thermal
convection. Please see Figure 2-1: Mounting
NOTE: If the controller is to be installed in an enclosed box, it is
important to ensure reliable heat dissipation through the box.
Step 2：Connect the system in the order of ❶battery ❷load ❸PV array
in accordance with Figure 2-2,”Schematic Wiring Diagram”and disconnect the
system in the reverse order❸❷❶.
NOTE:While wiring the controller do not close the circuit breaker or fuse
and make sure that the leads of "+" and "-" poles are connected correctly.
NOTE: A fuse which current is 1.25 to 2 times the rated current of the
controller must be installed on the battery side with a distance from the
battery not greater than 150 mm.
NOTE: If an inverter is to be connected to the system, connect the inverter
directly to the battery, not to the load side of the controller.
Step 3：Grounding
As the TRIRONNseries is a common negative controller, the negative poles of the PV
array, battery and load can be grounded together.
NOTE: The controllercan also be used in a common positive system. In this
case, the negative poles of the controller, PV and load can’t be grounded
together, but only one of them can be grounded.
