MPPT Technology Explained:
The controller utilizes Maximum Power Point Tracking (MPPT) to extract the maximum possible power from solar arrays for battery charging. This process is fully automatic and adapts to changing environmental conditions to ensure optimal energy harvest throughout the day.
- Increased Current: When the solar array's maximum power point voltage (Vmp) is higher than the battery voltage, the controller proportionally increases the battery charging current to balance input and output power. This current boost is crucial for systems where solar panel Vmp is typically higher than battery voltage.
- Advantages over Traditional Controllers: Unlike traditional controllers that directly connect the solar array to the battery (limiting operation to a lower voltage range), MPPT controllers operate at the maximum power point, significantly improving energy capture. This also allows for savings in wiring due to reduced current.
2. Safety Instructions
Please read this manual thoroughly before installation and operation. Keep it for future reference. Only qualified professionals should install and service this device.
General Safety Warnings:

3. Installation
Installation must be completed by professional technical personnel.
3.1 Selection of Installation Location
- Surface: Install on a solid, non-flammable surface.
- Accessibility: The installation location must be accessible at all times and allow for easy removal of the controller.
- Temperature: Ambient temperature should be between -20°C and 50°C for optimal operation. Avoid direct sunlight to prevent overheating and power loss.
- Flammable Materials: Do not install near highly flammable materials or in areas with potential explosion hazards.
- Internal Components: Due to built-in thermal storage, do not touch the interior with bare hands after opening the housing while the controller is in operation.
3.2 Safety Distance
Ensure sufficient heat dissipation space around the controller:
| Description | Safety Distance |
|---|---|
| Side | 20 CM |
| High | 30 CM |
| Low | 30 CM |
3.3 MPPT Controller Connection
Incorrect wiring can pose a life-threatening risk. Always use a disconnect device for the solar panel array and ensure no voltage is present before connecting.
3.3.1 System Composition
The solar charging system typically consists of a solar panel array, the MPPT solar charge controller, and a battery bank. An inverter and AC loads can also be integrated.
3.3.2 Wiring Procedure
Important: Always connect the battery first, then the solar panels. Disconnect in reverse order (solar panels first, then battery).
- Battery Connection: Connect the battery bank to the controller. Ensure correct polarity (+ to + and - to -). Use a circuit breaker and ensure it is disconnected during connection. A short circuit can cause fire or explosion.
- DC Load Connection (if applicable): For models with a DC load interface (40A, 60A, 80A), connect your DC loads. Models 100A and 120A do not have a DC load interface.
- PV Module Connection: Connect the solar panel array to the controller. Be extremely cautious as PV modules can generate high voltage. Ensure the circuit breaker for the PV modules is disconnected during connection.

| Circuit Breaker | 63A | 80A | 100A | 125A | 125A |
3.4 Power-On Test Run
Before powering on, ensure all DC connecting wires have correct polarity.
- Verify all positive and negative poles of connecting wires are correct. Measure the open-circuit voltage of PV modules to ensure it's within the controller's operating range.
- Turn on the circuit breaker connecting the controller to the battery.
- Turn on the circuit breaker connecting the controller to the solar panels.
- The controller will enter self-test mode. If conditions are correct, it will switch to working mode. If not, a fault prompt will display. Refer to the troubleshooting section.
- The default battery type is maintenance-free lead-acid. Adjust settings if needed (see Battery Type Setting in Operation section).
