6. Installation and Setup
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully:
6.1 Mounting the Controller
- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture.
- Ensure there is sufficient space around the controller for heat dissipation.
- Mount the controller vertically on a non-flammable surface using appropriate fasteners.
6.2 Wiring Connections
Important: Always connect the battery first, then the solar panel, and finally the DC load. Disconnect in the reverse order (load, then solar, then battery).
- Connect the Battery: Connect the positive and negative terminals of your battery bank to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the battery voltage.
- Connect the Solar Panel: Connect the positive and negative terminals of your solar panel array to the corresponding PV terminals on the controller. Ensure correct polarity.
- Connect the DC Load (Optional): If using a DC load directly from the controller, connect its positive and negative terminals to the corresponding load terminals.
- Connect the Temperature Sensor: Plug the included temperature sensor cable into the designated port on the controller and attach the sensor to the battery bank. This ensures accurate temperature compensation for charging.

6.3 Initial Power-Up
Once all connections are secure and verified for correct polarity, the controller will power on. The digital display will show current system parameters.
7. Operating Instructions
The controller features an intuitive digital display and three buttons for navigation and parameter setting.
7.1 Digital Display Overview
The display provides real-time information on PV input, battery status, and load output. Icons indicate charging status, battery level, and load status.
- PV: Displays solar panel voltage and current.
- BATT: Shows battery voltage and charging current.
- OUTPUT: Indicates load current.
- Icons: Represent solar charging, battery status, and load on/off.
7.2 Button Functions
- Up (▲): Navigate up through menu options or increase parameter values.
- Down (▼): Navigate down through menu options or decrease parameter values.
- M (Menu/Confirm): Enter menu, confirm selection, or switch display modes.
7.3 Parameter Settings
To access and modify parameters:
- Press and hold the 'M' button for a few seconds to enter the main menu.
- Use the 'Up' and 'Down' buttons to navigate through different settings (e.g., battery type, charge voltage, discharge voltage).
- Press 'M' to select a parameter for editing.
- Use 'Up' and 'Down' to adjust the value.
- Press 'M' again to confirm the new value and exit the editing mode for that parameter.
- Press and hold 'M' to exit the menu.
Battery Type Selection: It is critical to select the correct battery type (e.g., Lead-Acid, Lithium) in the settings to ensure proper charging algorithms and prevent battery damage.
8. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Loose connections can cause resistance and overheating.
- Clean the Controller: Keep the controller's exterior clean and free of dust. Ensure ventilation openings are not obstructed. Use a dry cloth for cleaning.
- Monitor Performance: Regularly check the display for normal operation and parameter values. Note any unusual readings.
