Introduction
The Biling Solar Drip Irrigation System is designed to provide automatic watering for your plants, especially suitable for balconies, gardens, and greenhouses. This system utilizes solar power to operate, featuring a 2200 mAh battery for continuous operation. It can efficiently water 15 to 20 potted plants, saving up to 80% water compared to traditional methods. This manual provides detailed instructions for the proper installation, operation, and maintenance of your irrigation system.
Safety Information
- Ensure the solar panel is installed in a location that receives optimal sunlight for efficient charging.
- Always place the controller unit above the water source to prevent siphoning and ensure proper pump function.
- Before inserting T-connectors and drippers, dip the end of the hose in warm water for approximately 1 minute to soften it, making insertion easier and preventing damage.
- Regularly check the water reservoir to ensure it does not run dry, as this can damage the pump.
- Keep the system components away from extreme temperatures and direct physical impact.

Setup Instructions
Follow these steps to set up your Biling Solar Drip Irrigation System:
- Prepare the Hose: Dip the end of the water hose in warm water for about 1 minute. This will soften the hose, making it easier to insert the T-connectors and drippers.
- Connect the Filter: Attach the filter to the inlet port of the controller. Place the filtered end into your water reservoir (e.g., a bucket or tank).
- Position the Controller: Mount the controller unit in a suitable location, ensuring it is positioned higher than your water source. This is crucial to prevent siphoning and ensure the pump functions correctly.
- Install the Solar Panel: Connect the solar panel to the controller. Place the solar panel in a sunny spot where it can receive maximum direct sunlight throughout the day for optimal charging. Use the provided ground stake if installing in soil.
- Route the Hose and Install Drippers: Connect the 15-meter water hose to the outlet port of the controller. Route the hose to your plants. Cut the hose at appropriate points and insert T-connectors. Attach drippers to the T-connectors and place them near the base of each plant.
- Consider Plant Water Needs: Plants with higher water requirements should be placed closer to the controller unit, while plants needing less water can be positioned further along the hose line.
- Secure Connections: Ensure all hose connections, T-connectors, and drippers are securely fitted to prevent leaks.
