6. Setup
6.1. Component Identification
The image displays the front panel of the Go Power! GP-PWM-10-FM Digital Solar Controller. It features a large backlit LCD screen showing various parameters such as solar input, battery charge level, voltage (V), and current (kAh). Below the screen are two control buttons labeled 'A' and 'B'. The bottom section shows connection points for solar panels and battery, along with the 'Go Power!' logo and 'MAXIMUM POWER BOOST TECHNOLOGY'.
6.2. Wiring Instructions
- Connect to Battery: First, connect the controller to your battery bank. Ensure correct polarity (positive to positive, negative to negative). This allows the controller to detect the battery voltage and type.
- Connect to Solar Panels: Next, connect your solar panels to the controller. Again, observe correct polarity. The controller will begin regulating the charge from the panels to the battery.
- Wire Gauge: The controller can handle up to #6 AWG wire. Ensure appropriate wire gauge is used for your system to minimize power loss and ensure safety.
Note: Always connect the battery to the charge controller before connecting the solar panels. Disconnect solar panels before disconnecting the battery.
6.3. Battery Type Selection
The GP-PWM-10-FM is adjustable for Lithium, AGM, GEL, and Lead Acid batteries. Refer to the controller's interface or accompanying quick start guide to select the appropriate battery type for your system. Correct battery type selection is crucial for optimal charging and battery longevity.
7. Operating Instructions
7.1. Digital Display
The backlit digital display provides real-time information about your solar charging system. It typically shows:
- Battery Voltage (V): The current voltage of your battery bank.
- Charging Current (kAh): The current flowing from the solar panels to the battery.
- Battery State of Charge (%): An estimated percentage of your battery's capacity.
- Solar Input Indicator: An icon indicating active solar charging.
- Battery Type Indicator: Shows the currently selected battery type (SEALED, AGM, FLOODED).
7.2. USB Charging
The integrated USB port allows for convenient charging of small electronic devices. Connect your device's USB cable to the controller's USB port. The USB charging function operates independently of the main battery charging process.
7.3. Control Buttons (A & B)
The 'A' and 'B' buttons are used to navigate through the display menus and adjust settings. Consult the detailed product manual for specific button functions related to battery type selection and other configurable parameters.
8. Maintenance
- Regular Cleaning: Keep the controller's display and casing clean and free from dust and debris. Use a soft, dry cloth.
- Connection Checks: Periodically inspect all wiring connections to ensure they are tight and free from corrosion. Loose connections can lead to power loss or system malfunction.
- Environmental Conditions: Ensure the controller is not exposed to extreme temperatures or moisture beyond its operating specifications.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Power off | Loose battery connection, discharged battery, blown fuse. | Check battery connections, charge battery, inspect and replace fuse if necessary. |
| Battery not charging | No solar input (e.g., shade, night), loose solar panel connection, incorrect battery type setting. | Ensure panels are in direct sunlight, check solar panel wiring, verify battery type setting. |
| USB not charging devices | Device not compatible, low battery voltage, faulty USB cable. | Try a different device/cable, ensure battery is sufficiently charged. |
10. Warranty and Support
