Please save this manual for future review.

This manual contains safety, installation and operation for Maximum Power Point

Tracking (MPPT) TRIRON N series controller ("the controller" as referred to in this

manual).

General Safety Information

Read carefully all the instructions and warnings in the manual before installation.

No user serviceable components inside the controller. DO NOT disassemble or

attempt to repair the controller.

Mount the controller indoors. Prevent exposure to the elements and do not allow

water to enter the controller.

Install the controller in a well ventilated -place. The controller’s heat sink may

become very hot during operation.

It is suggested to install appropriate external fuses/breakers.

Make sure to switch off all PV array connections and the battery fuse/breakers

before controller installation and adjustment.

Power connections must remain tight to avoid excessive heating from loose

connection.

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.

Features：

Ultra-fast tracking speed and guaranteed tracking efficiency.

Automatic limitation of the charging power and current

Wide MPP operating voltage range.

Multiple load work modes

Support the lead-acid and lithium batteries with the needed tem. compensation

Real-time energy statistics function.

Overheating power reduction function

LCD and indicators to display operating data and status of the system

User-friendly buttons for comfortable and convenient operation

Master and slave RS485 communication modules design, reading the load or

inverter operating data

Control the inverter switch through the relay interface

Provide 5VDC power through the dual USB output interface to charge

electronic devices

1.3 Module Types

1-Power Modules

The Power Modules control PV battery charging & load discharging without any without any display or interface modules installed

–they can operate on their own. If a display or interface module is installed, it will be powered by the Power module and the

appropriate module driver will be loaded.

NOTE: The power module can be operated independently without any other modules.
