5. Setup & Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully.
5.1 Site Selection
- Install the controller indoors, away from direct sunlight, high temperatures, and water.
- Ensure the mounting surface is strong enough to support the controller's weight.
- Allow at least 6 inches (15 cm) of clearance around the controller for proper ventilation.
5.2 Wiring Sequence
Important: Always connect the battery first, then the solar panels, and finally the load (if applicable). Disconnect in the reverse order.
- Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the battery voltage.
- Connect the Solar Panels: Connect the positive and negative terminals of your solar panel array to the corresponding PV input terminals on the controller. Ensure correct polarity.
- Connect the Load (Optional): If your controller has load terminals, connect your DC load to these terminals. Ensure correct polarity.

Note on PV Over-Voltage Protection: The controller has PV over-voltage protection. If the PV open-circuit voltage (Voc) exceeds 180V, the controller may be damaged. Ensure your solar array voltage is within the specified limits.
6. Operating Instructions
Once installed, the controller will begin operating automatically. The LCD display provides essential information and allows for configuration.
6.1 LCD Display and Buttons
The LCD screen displays real-time data such as battery voltage, charging current, PV voltage, and various operational statuses. Use the buttons below the screen to navigate menus and adjust settings.
- PROG (Program): Enters/exits programming mode.
- ESC (Escape): Exits current menu or cancels an action.
- UP/DOWN Arrows: Navigate through menu options or adjust values.
- ENTER: Confirms selection or enters a submenu.
6.2 Battery Type Selection
The controller supports various battery types. It is crucial to select the correct battery type for optimal charging and battery longevity.
Figure 4: The controller is compatible with Lithium, Sealed Lead Acid, and Vented Gel batteries. Refer to the manual for specific settings for each type.
