This manual contains important safety, installation and operating instructions for the

MPPT solar controller.

The following symbols are used throughout this manual to indicate potentially

dangerous conditions or mark important safety instructions.

WARNING:

Indicates a potentially dangerous condition. Use extreme caution when performing this

task.

CAUTION:

Indicates a critical procedure for safe and proper operation of the controller.

NOTE:

Indicates a procedure or function that is important for the safe and proper operation of

the controller.

Safety Information

Read all the instructions and cautions in the manual before beginning installation.

There are no user serviceable parts inside the MPPT charger. Do not disassemble

or attempt to repair the controller.

Disconnect all sources of power to the controller before installing or adjusting the

controller setting.

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

allow water to enter the controller.

Install the controller in a location that prevents casual contact. The controller can

become very hot during operation.

Use insulated tools when working with batteries.

Avoid wearing jewelry during installation.

The battery bank must be comprised of batteries of same type, make and age.

Do not smoke near the battery bank.

Power connections must remain tight to avoid excessive heating from a loose

connection.

Use properly sized conductors and circuit interrupters.

WARNING: A battery can present a risk of electrical shock or burn from

large amounts of short-circuit current, fire, or explosion from vented gases. Observe

proper precautions.

CAUTION: When replacing batteries, use properly specified sizes, type

and rating based on application and system design.

About this Manual

This manual provides detailed installation and usage instructions for the

MPPT solar charge controller. Only qualified electricians and technicians

who are familiar with solar system design and wiring practices should install

the MPPT controller. The usage information in this manual is intended for the

system owner/operator.

2.1 Overview

The MPPT controller is an advanced maximum power point tracking solar battery

charger. The controller features a smart tracking algorithm that finds and maintains

operation at the solar array peak power point, maximizing energy harvest.

The MPPT controller charging process has been optimized for long battery life and

improved system performance. Self-diagnostics and electronic error protections

prevent damage when installation mistakes or system faults occur. The controller also

features four adjustable setting switches, RS485 communication port and terminal for

remote battery temperature measurement.

Please take the time to read this operator’s manual and become familiar with the

controller. This will help you utilize the many advantages of the MPPT Controller that for

your PV system.

3. Installation

3.1 General Information

The mounting location is important to the performance and operating life of the

controller. The environment must be dry and protected from water ingress. If required,

the controller may be installed in a ventilated enclosure with sufficient air flow. Never

install the controller in a sealed enclosure. The controller may be mounted in an

enclosure with sealed batteries, but never with vented/flooded batteries. Battery

fumes from vented batteries will corrode and destroy the controller circuits.

Multiple controllers can be installed in parallel to the same battery bank to achieve

higher charging current. Additional controllers, connected in parallel, may be added in

the future. Each controller must have its own solar array.

CAUTION: Equipment Damage or Risk of Explosion

Never install the controller in an enclosure with vented/flooded batteries. Battery fumes

are flammable and will corrode and destroy the controller circuits.

CAUTION: Equipment Damage

When installing the controller in an enclosure, ensure sufficient ventilation. Installation

in a sealed enclosure will lead to over-heating and decreased product lifetime.

The installation is straight-forward, but it is important each step is done correctly and

safety. A mistake can lead to dangerous voltage and current levels. Be sure to carefully

follow each instruction. Read all instructions first before beginning installation.

Recommended Tools:

Wire strippers

Wire cutters

Phillips screwdriver

Slotted screwdrivers

Pliers

Drill

Drill bit

Level

Hacksaw (cutting conduit）

3.2 Controller Installation

Step 1-Remove the wiring box cover

CAUTION: Shock Hazard

Disconnect all power sources to the controller before removing the wiring box cover.

Never remove the cover when voltage exists on any of the power connections.

Use a #4 Phillips screw driver to remove the four screws that secure the wiring box

cover as show in figure below.

Battery charging setting

It is important to select the battery type that match the system battery to ensure proper

charging and long battery life. Refer to the specifications provided by the battery

manufacturer and choose a setting that best fits the recommended charging profile.
