2.1 Overview
2.1 Features
Thank you for selecting the MPPT solar charge controller.The MPPT
is essentially a smart DC to DC converter which has been optimized to harvest maximum
energy from the PV array in battery based solar electric systems by using a variety of maxi-
mum power point tracking (MPPT) strategies. The controller’s secondary objective is to
ensure that the batteries receive a full charge without becoming overcharged. This is accom-
plished through a four stage charging process
Please take the time to read this operator’s manual and be familiar with the controller.
This will help you make full use of the many advantages the MPPT can provide for your PV
system.

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 in-
stalled in a ventilated enclosure with sufficient air flow. Never install the MPPT unit 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
MPPT circuits.
Multiple MPPT can be installed in parallel on the same battery bank to achieve higher
charging current. Additional parallel controllers can also be added in the future. Each MPPT
must have its own solar array.
!CAUTION: Equipment Damage or Risk of Explosion
Never install the MPPT in an enclosure with vented/ Flooded batteries. Battery
fumes are flammable and will corrode and destroy the MPPT circuits.
!CAUTION: Equipment Damage
When installing the MPPT in an enclosure, ensure suf ficient ventilation.
Installation in a sealed enclosure will lead to over-heating and a decreased product
lifetime.
NOTE : Mounting
When mounting the Mas MPPT ,ensure free air through the controller heat sink fins. There
should be at least 150mm of clearance above and below the controller to allow for cooling. If mounted
in an enclosure, ventilation is highly recommended.

Step 2: DC load Wiring
WARNING:Please use the appropriate cable size according to load rating. Please refer to
important Safety Warnings Section for the details. It will prevent internal high temperature.
1. Attach the mounting hanger to the bottom of the MPPT with the M6 screw
provided as shown in figure 3-1.
2. Place the MPPT on a vertical surface protected from direct sunlight, high
temperatures, and water. The MPPT requires at least 150 mm of clearance
right and left. flow as shown in figure 3-2 below.

The load output will provide battery voltage to connected loads such as lights,monitors and
other electronic devices.
● connect load positive(+) wire to the positive terminal of the unit and load negative(-) wire
to the negative terminal of the unit.
● install a DC Breaker or a DC fuse holder in a positive wire. The rating of the DC Breaker/
Fuse must be rated to 125% of the maximum load current or more. Keep the DC breaker off or
do not install the DC fuse.
● See Section 4.3 Setting Operation for more detials about load control.

WARNING: Risk of explosion or fire ! Never short circuit positive(+) and negative(-) or cables
● connect battery positive(+) wire to the positive terminal of the unit and battery negative(-)
wire to the negative terminal of the unit. Use #6 to #7 AWG wire rated for 75º C for Battery
connections.
●install a DC Breaker or a DC fuse holder in a positive wire. The rating of the DC Breaker/
Fuse must be rated to 125% of the maximum charging current or more. Keep the DC breaker
off or do not install the DC fuse.
1) Multiple batteries in series connection (Refer to Fig.3-5): All batteries must be equal in
voltage and amp hour capacity. The sum of their voltage must be equal to the nominal DC
Voltage of the unit.

Step 4: Solar Module Wiring
WARNING: Risk of electric shock! Exercise caution when handing solar wiring. The solar
array high voltage output can cause severe shock or injury. Cover modules form the sunlight
before installing solar panel wiring.
1) Multiple solar modules in series connection(Refer to Fig.3-7): All modules must be
equal in voltage.The sum if their voltage must be equal to the nominal DC Voltage of the
unit. The sum of their solar power must exceed the maximum capacity of the unit.
