1 Product Overview
This product can real-time detect the power generation of the solar panel and track the maxi-
mum voltage-current value to achieve the maximum power output for charging the battery. It is
designed for off-grid photovoltaic systems and serves as the core control component that coor-
dinates the operation of the solar panel, battery, and devices in off-grid photovoltaic systems.

2 Installation
2.1 Note before Installation
Installation Position:
炴Install the MPPT controller in a dry, well-ventilated location that allows for easy disassembly
and maintenance.
炴Do not install on flammable building materials; do not install on highly flammable
materials; do not install in hazardous areas with explosion risks.
炴Avoid exposure to harsh environments, such as high humidity, flammable and explosive
areas, or places with excessive dust accumulation.
炴Do not install the MPPT controller in enclosures with open or liquid-filled batteries.
炴The heat sink of the MPPT controller may reach temperatures exceeding 40 煓during
operation, so install the MPPT controller in a place where it is not easily touched.
炴Ensure adequate ventilation when installing the MPPT controller inside an enclosure.
Installing it in a sealed enclosure may cause overheating, reduced power operation, and
shortened product lifespan.
Safety Information:
炴Use insulated tools during installation.
炴Disconnect all power sources to the MPPT controller before installing or adjusting the
MPPT.
炴Do not operate or install the MPPT controller alone. Please ask nearby people for
assistance in case of an accident.
炴The MPPT controller must be installed by qualified technicians or personnel trained in safe
installation practices according to the electrical regulations of the respective country.
Proper Use:
炴This MPPT controller is designed solely for solar power generation. Connecting it to any
other power sources, such as wind turbines or generators, may void the warranty.
炴There are no user-serviceable parts inside the MPPT. Do not disassemble or attempt to
repair the MPPT controller.
炴A disconnect or isolation device must be available for safely and conveniently disconnecting
the MPPT from the system.

15
2.2 Installation
Step 1: Unpack and Check
Check the MPPT controller for any transportation damage or impact and ensure the
specifications match the order.
Step 2: Check MPPT controller Parameter Limits
Ensure that, under maximum temperature compensation, the open-circuit voltage (Voc) of the
solar panel array does not exceed the rated voltage of the MPPT (refer to chapter 1.5 for details).
Multiple MPPT controllers can be installed in parallel on the same battery bank to obtain higher
charging current. Each parallel MPPT must be connected to an independent solar panel.
Step 3: Determine Installation Space
To ensure air circulation, leave at least 15 cm (6 inches) of space above and below the MPPT
controller and 10 cm (3.97 inches) on the sides. Do not install the MPPT controller inside a
closed enclosure.
Note: The rear heat sink must be installed in a vertical direction (allowing for vertical
airflow).
Step 4: Assemble and Install Mounting Bracket
Align the mounting bracket with the accessory mounting holes on the MPPT controller and
secure them using M4 countersunk screws.

Step 5: Drill Mounting Holes on the Installation Position
Measure and mark the distance on the installation position, drill four 6mm diameter holes (if
using composite material bulkheads, insert plastic expansion particles into the holes).
Step 6: Secure the MPPT Controller to the Installation Position
Align the MPPT controller's mounting holes with the holes created in Step 5 and secure the
MPPT controller to the installation position using M4 self-tapping screws or M4 bolts, then
tighten the screws.
Step 7: Connect the Cables
1瀭 Before connecting, distinguish between input and output wires (see 1.2 Parts and
Diagrams). The wire core definition is as follows: Red wire core is positive (+), and black
wire core is negative (-).
2瀭 Install a circuit breaker or fuse with a rating equal to or greater than the charging current
between the cables at No. 滦and 滧, and keep it in the OFF state.
3瀭 Connect the terminals at No. 滨and 滩according to the corresponding positive and
negative positions (see 1.6.2 Battery Connector Definitions).
4瀭 Connect the RJ45 communication cable and temperature sensor at No. 滪(see 1.6.1 6P
Connector Definitions).
This MPPT controller can prevent reverse current leakage at night, so there is no need
to add diodes in the system.
Avoid connecting the photovoltaic input to the MPPT controller's output power cable to
prevent damage to the MPPT controller's internal circuitry and invalidate the warranty.
The installation must comply with electrical specifications. Select appropriate specifications
for circuit breakers and fuses based on application requirements.
Ensure secure and stable connections, use cable clamps to secure cables to prevent
movement in mobile applications, and maintain tight connections to avoid overheating due to
loose connections.
There is a risk of electric shock. Before connecting, test the impedance between all terminal
connections and ground.

The negative terminal of the MPPT should be connected (common negative). If necessary,
ground the MPPT controller according to instructions, local specifications, and regulatory
requirements.
Step 8: Power On
Before powering on, ensure all cable connections are secure.
1瀭 Close the breaker at No. 滦(Battery). If there is power in the battery, the MPPT controller
will run automatically.
2瀭 After the MPPT controller is powered on normally, close the breaker at No. 滧, and the
solar panels will start functioning normally.
If the MPPT controller does not start after closing the No. 滦breaker, it may be due to the
battery being depleted. Closing the No. 滧breaker will enable the MPPT controller to be
powered on properly using solar panel input.
