1. Product Overview
The GCSOAR PWM Solar Charge Controller (Model GC1024) is designed for solar power systems, including home solar setups, solar street lights, patio lights, billboards, outdoor camping systems, and marine solar applications. This controller efficiently manages power flow from solar panels to batteries and loads, ensuring system stability and battery longevity.
Key Features:
- Intelligent SOC control chip for stable system operation.
- Overcharge, overdischarge, anti-backflow, and overheating protection.
- Automatic 12V/24V battery type recognition.
- Dual 5V/2A USB outputs for charging mobile devices.
- Series PWM main charging circuit for improved efficiency.
- Enhanced LCD display for intuitive parameter adjustment.
- Constructed with SMT chip production process, high-quality PCB, and industrial-grade chip for durability in various environments.
2. Safety Instructions
- Ensure the battery has sufficient voltage for the controller to recognize its type (12V/24V) before installation.
- Battery cables should be as short as possible to minimize power loss.
- This regulator is ONLY suitable for lead-acid batteries: OPEN, AGM, GEL. It is NOT suitable for lithium batteries or Ni-MH batteries.
- This controller is ONLY suitable for working with photovoltaic solar panels. Do NOT connect to other DC or AC power sources.
- Always connect the battery first, then the load, and finally the solar panel. Disconnect in the reverse order: solar panel, then load, then battery.

5. Operating Instructions
The controller's LCD display provides real-time information and allows for parameter adjustments.
LCD Display Navigation:
Press the 'MENU' button to cycle through different display interfaces, showing battery voltage, solar panel current, load current, temperature, and accumulated power generation/consumption.
Image: Examples of the LCD display showing different parameters such as battery voltage, charging current, load status, and timer settings.
Parameter Settings:
To enter the setting mode, press and hold the 'MENU' button for 5 seconds. Use the 'UP' and 'DOWN/ON/OFF' buttons to adjust values. Press 'MENU' again to confirm and move to the next parameter. If no operation is performed for 5 seconds, the controller will automatically save settings and exit.
- Battery Type Setting: In the battery voltage interface, press and hold the 'SET' button for 5 seconds to enter battery type setting. Use 'MENU' to select between Sealed (Default), Gel, and Flooded. Wait 5 seconds or press 'SET' to confirm.
- Load Mode Setting (Timer): In the load mode interface, press and hold the 'SET' button for 5 seconds until the number begins flashing. Use 'MENU' to set the parameter (e.g., 24H for 24-hour load, 0H for dusk-to-dawn, or timed settings). Press 'SET' to confirm.
- Load ON/OFF: From the main display, press the 'DOWN/ON/OFF' button to manually turn the load on or off.
USB Charging:
The dual USB ports provide 5V/2A output for charging mobile phones, tablets, and other compatible devices. Simply connect your device to one of the USB ports.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller.
- Keep the controller in a cool, dry, and well-ventilated area to prevent overheating.
- Periodically check all wire connections for tightness and corrosion.
- Clean the controller's exterior with a dry cloth. Avoid using liquids or abrasive cleaners.
- Monitor the LCD display for any error codes or unusual readings.
7. Troubleshooting
If you encounter issues with your GCSOAR PWM Solar Charge Controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| LCD display not turning on | Battery not connected or low voltage | Check battery connections and ensure battery voltage is above minimum operating level. |
| No charging from solar panel | Solar panel not connected, insufficient sunlight, or reverse polarity | Check solar panel connections and polarity. Ensure adequate sunlight. |
| Load not working | Load not connected, load current too high, or load output disabled | Check load connections and ensure load current is within specifications. Press 'DOWN/ON/OFF' button to enable load output. |
| Overcharge/Overdischarge protection active | Battery voltage exceeded limits | The controller automatically protects the battery. Ensure correct battery type setting. |
