3. Safety Precautions
WARNING: Failure to follow these safety instructions may result in injury or damage to the controller and other components.
- Ensure all connections are correct and secure before powering on the system.
- Strictly adhere to the recommended maximum input power for wind (200W) and solar panels (30A=300W, 40A=400W, 60A=600W, 100A=700W). Exceeding these limits can damage the controller.
- The voltage value of the solar panel should be approximately 1.5 times the voltage value of the battery being recharged.
- It is strictly forbidden to short-circuit the boost output power port.
- Always connect the battery first, then the solar panel or wind generator, and finally the load. Disconnect in reverse order.
- Do not reverse the polarity of any connections.
- This controller is suitable for lead-acid batteries (open, sealed, colloidal). For lithium batteries, user-defined parameters are required.
4. Installation and Connection
Follow these steps for proper system connection. Refer to the diagrams for visual guidance.
4.1 General Connection Steps
- Connect the positive and negative terminals of the battery to the controller. The controller will automatically detect the battery voltage.
- Connect the positive and negative terminals of the load to the controller. Ensure correct polarity.
- Connect the solar panel to the controller.
- Connect the wind generator to the controller.
- For boost charging function or power output, ensure no short circuits at any time.
4.2 Specific Connection Modes
4.2.1 Standard Charging Connection Mode
In this mode, the wind input is 15V-50V, and the solar panel input is 18V-90V. It charges 12V, 24V, 36V, 48V, or 60V batteries. The output load voltage corresponds to the battery voltage. Connect the battery first, then the solar panel or wind motor, and finally the load. Set the corresponding voltage value for the rechargeable battery and relevant charging parameters; the controller has a memory function.
4.2.2 Dual Battery Charging Connection Mode
This mode supports charging two batteries simultaneously. For wind input 15V-50V and solar panel 18V input, it charges battery ① (12V) and battery ② (24V, 36V, 48V, 60V). For solar panel 36V input, it charges battery ① (24V) and battery ② (36V, 48V, 60V). The output load corresponds to the battery voltage. Connect batteries first, then solar/wind, then load. Set parameters for both batteries.
4.2.3 Boost Charging Connection Mode (Electric Vehicle Charging)
For wind input 15V-50V and solar panel 18V input, battery ① is not connected. Connect to the negative pole of battery ② (24V, 36V, 48V, 60V) for charging. For solar panel 18V-36V input, battery ① is not connected. Connect to the negative pole of battery ② (24V (PV18V), 36V, 48V, 60V (PV36V)) for charging. The output load corresponds to the battery voltage. Connect battery ② first, then solar/wind, then load. Set parameters for battery ②.
4.2.4 No Battery Working Mode
In this mode, the controller can drive a load directly without a battery. For wind input 15V-50V and solar panel 18V input, battery ① is not connected. Connect to the negative pole of load ② (24V, 36V, 48V, 60V) to drive it. The boost output voltage matches the load voltage. Connect the wind/hydraulic motor or solar panel (18V) first, then set the corresponding voltage value for the load, and finally connect the load. The controller retains settings with memory function.
