1. Important safety instructions
Save these instructions
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.

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.
