- Solar Panel Input: Connect your solar panel array here.
- Battery Connection: Connect to your battery bank.
- Load Output: Connect your DC loads (e.g., lights).
- Solar Panel Indicator: Shows solar panel activity.
- Battery Indicator: Shows battery charge status.
- Load Indicator: Shows load output status.
- Mode Setting: DIP switches for load control.
- Mount Holes: For securing the controller.
4.2 Wiring Connections
Connect the components in the following order to prevent damage:
- Connect the Battery: First, connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will detect the system voltage (12V or 24V) automatically.
- Connect the Solar Panel: Next, connect the solar panel to the charge controller. Ensure correct polarity.
- Connect the Load: Finally, connect the DC load to the charge controller. Ensure correct polarity.

Important: Always connect the battery first and disconnect the solar panel first when disassembling the system.
4.3 Mounting
Mount the controller using the provided mount holes (8) in a location that is protected from direct sunlight and excessive heat, but allows for adequate ventilation. Despite its waterproof rating, avoiding direct exposure to extreme elements can prolong its lifespan.

5. Operating Instructions
The controller features a "Dust to Dawn Intelligent Controller" with three load working modes, configurable via DIP switches.
5.1 Load Working Mode Setting
The controller's load output can be customized using the DIP switches (Mode setting, item 7 in Figure 2). Refer to the diagram below for specific settings.
Figure 5: Load Working Mode DIP Switch Settings
- Mode 1: Always On
Pull all DIP switches to the "OFF" position. The load output will remain ON 24 hours a day, provided the battery has sufficient charge. - Mode 2: Auto Dusk to Dawn
Push all DIP switches to the "ON" position. The load output will automatically turn ON at dusk and turn OFF at dawn. - Mode 3: Dusk to Dawn with Hours Setting
Push the DIP switches to the "ON" position as shown in the diagram (Figure 5) to set up working hours from 1 hour to 14 hours. The load will turn ON automatically at dusk and turn OFF after the set time duration. For example, "Light Control 1H" means the lights will be on for 1 hour only in Auto Light Control Mode.
5.2 Indicators
The controller features LED indicators to display the status of your solar system (refer to Figure 2 for locations):
- Solar Panel Indicator (4): Indicates solar panel activity and charging status.
- Battery Indicator (5): Shows the current charge level of the battery (e.g., FULL, NORMAL, LOWER, OVERLOW).
- Load Indicator (6): Indicates whether the load output is active.
6. Maintenance
The SUNER POWER solar charge controller is designed for minimal maintenance. However, periodic checks can ensure optimal performance and longevity.
- Inspect Connections: Periodically check all wiring connections for tightness and corrosion. Loose connections can cause voltage drops and overheating.
- Clean Controller: Although waterproof, keep the controller's exterior clean from dust and debris. Use a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Check Indicators: Regularly observe the LED indicators to ensure the system is operating as expected.
- Battery Health: Monitor your battery's health and charge level. Ensure it is compatible with the controller's charging parameters.
