Solar Irrigation Kit RainPoint IK15P — solar-powered irrigation controller kit for garden watering

RainPoint IK15P Solar Irrigation Kit provides an off-grid solution for automatic watering of up to 15 plants. The kit includes a built-in pump, a 5 W solar panel and a 2000 mAh rechargeable battery, with an LCD display and control knob for scheduling. It draws water from a reservoir and delivers it to plant roots via tubes and drippers, allowing installation on balconies, terraces or garden beds without connection to mains water or electricity.

Advantages

The system operates using solar power with the option to charge via USB-C, enabling independent, cordless installation. Adjustable watering duration (30 seconds to 30 minutes) and frequency (every 12 hours to 7 days) let you tailor irrigation to different plants and weather. Built-in features such as a water level sensor, filter, check valve and selectable delay or manual modes increase reliability and protect the system from contamination and backflow.

Suitable for

• Balconies and terraces
• Small garden beds and raised planters
• Lawns and small allotments without mains supply
• Seasonal plant care during holidays or absence

When it may not be suitable

The kit is intended for up to 15 plants and relies on a reservoir as the water source; it is not suitable where high-volume or high-pressure irrigation is required. In locations with prolonged low sunlight the solar charging may be insufficient without frequent USB-C recharging.

How to use

Place the solar panel in a location with good sunlight and mount the controller near the water reservoir. Connect the pump to the main hose and lay side lines with drippers to each plant. Use the control knob and LCD display to set watering frequency (12 hours to 7 days) and duration (30 seconds to 30 minutes). The pump draws water from the reservoir automatically according to the programmed schedule; a manual mode and delay timers (24, 48 or 72 hours) are available for temporary adjustments.

What to consider before purchase

• Number of plants to water (kit supports up to 15 drippers)
• Availability of a water reservoir and access for pump intake
• Typical sunlight exposure for solar charging or need for USB-C charging
• Required watering volume and whether low-pressure drip irrigation meets plant needs

Usage recommendations

Position the solar panel where it receives maximum daily sun and keep the filter clean to prevent clogging; check the water level sensor regularly and use the manual mode when refilling the reservoir to avoid dry running.
