- Connect Battery: Connect the battery to the 'BATTERY' terminals (+ to + and - to -). Ensure correct polarity.
- Connect Solar Panels: Connect the solar panel array to the 'SOLAR' terminals (+ to + and - to -). Ensure correct polarity and that the maximum PV input voltage does not exceed 160VDC.
- Connect Load: Connect your DC load to the 'LOAD' terminals (+ to + and - to -).
- Parallel Connection (Optional): The controller supports parallel operation for increased capacity. To connect two 60A controllers in parallel for a total of 120A, follow the specific instructions for parallel wiring, ensuring all connections are secure and correctly polarized.
2.3 PV Module Configuration
The maximum PV open-circuit voltage is 160Vdc. Refer to the table below for recommended configurations based on your system voltage:

3. Operating Instructions
3.1 Power On
Once all connections are secure, the controller will power on automatically. The LCD display will show the current system status.
3.2 Battery Voltage Auto-Detection
The controller automatically detects the system voltage (12V, 24V, 36V, or 48V) upon initial connection to the battery. Ensure your battery bank matches one of these voltages.
3.3 Charging Algorithm
The controller utilizes a 3-stage MPPT charging algorithm: constant current, constant pressure, and floating charging. This ensures fast, efficient, and safe charging, optimizing each charging cycle and maintaining battery capacity.
3.4 Parallel Operation
The parallel operation function allows for easy expansion of your solar panel configuration and energy storage capacity. Up to 12 units can be connected in parallel to increase the total charging current.
