2. Product Overview and Features
2.1 Superior MPPT Technology
This controller incorporates an advanced Maximum Power Point Tracking (MPPT) algorithm to swiftly track the maximum power point of your photovoltaic (PV) array. This ensures a tracking efficiency of no less than 99.5%, significantly enhancing energy utilization within your solar system. It's important to note that this controller integrates both MPPT and PWM charging technologies, offering high charging efficiency and consistent performance.
2.2 Versatile Design and User Interface
The controller features a multi-function LCD with a backlight display and an integrated clock. It offers seven distinct operating modes to suit various application needs:
- Charging Mode
- Light Control Mode
- Light Control + Time Delay Control Mode
- Universal Control Mode
- Manual Control Mode
- Timing Control Mode
The upgraded version supports precise time control, allowing connected devices to be automatically powered on and off according to user-defined schedules. The screen can also maintain a continuous bright state without entering hibernation or lock mode.
2.3 User-Centric Display and Controls
The LCD dynamically displays operational data and the working status of the equipment. Key parameters visible include:
- Working Mode
- Battery Voltage
- PV Charging Current
- Battery Discharging Current
- Product Working Temperature
- Delay Time
For configuration adjustments or restoring default settings, a 'reset to factory settings' feature is available, providing a quick and effective solution.

7. Maintenance
To ensure the long-term performance and reliability of your ELUSH 100A MPPT Solar Charge Controller, consider the following maintenance guidelines:
- Regular Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Cleanliness: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
- Ventilation: Ensure the installation location provides adequate ventilation to prevent overheating, especially given the aluminum base plate designed for heat dissipation.
- Environmental Conditions: Protect the controller from direct sunlight, moisture, and extreme temperatures outside its operating range.
8. Troubleshooting
If you encounter issues with your solar charge controller, consider the following common troubleshooting steps:
8.1 Device Not Starting or Displaying Data
- Check Battery Connection: Ensure the rechargeable battery is connected first and has sufficient power to activate the controller. The controller requires battery power to operate.
- Verify Solar Panel Connection: Confirm that solar panels are connected correctly after the battery.
- Inspect Wiring: Check all wiring for loose connections, breaks, or incorrect polarity.
8.2 Low Charging Efficiency
- Solar Panel Output: Ensure solar panels are clean, unobstructed, and receiving adequate sunlight.
- Battery Type Setting: Verify that the correct battery type is selected in the controller's settings.
- System Voltage: Confirm that the system voltage (12V/24V/36V/48V) is correctly recognized by the controller.
- Hybrid Technology: Remember that this controller integrates both MPPT and PWM technologies. While efficient, its performance characteristics may differ from pure MPPT controllers.
8.3 Load Not Functioning
- Check Load Connection: Ensure the load is correctly connected to the load terminals.
- Load Mode: Verify the operating mode (e.g., light control, timing control) is correctly configured and enabled.
- Battery Voltage: If battery voltage is too low, the controller may disconnect the load to protect the battery from deep discharge.
