C18Q Solar-Powered Irrigation System – Q Series

Weather-Responsive, Ultra-Quiet, High-Efficiency Irrigation for Greenhouses and Gardens**

The C18Q represents the newest generation of solar-powered, weather-responsive irrigation systems. Developed using direct customer feedback, the Q Series delivers major improvements in efficiency, quiet operation, mounting flexibility and upgrade options, while maintaining all the core advantages of previous models.

Designed for growers who want fully automated, solar-powered watering, the C18Q adjusts output based on available sunlight: more sun delivers more water; less sun delivers less water.

What’s New in the Q Series

Quieter Operation

The new SPVQ pump delivers more water with less power and significantly reduced noise. It is barely audible during operation.

Higher Efficiency

Improved pump and electronics design increases performance with minimal solar energy usage.

Flexible Mounting Options

The controller can now be mounted:

• from the rear on a wall, post or shed, or

• from the front directly on greenhouse glass using the included adhesive mount, ensuring an unobstructed solar angle.

Upgradeable System

Optional upgrades include:

• a second pump for clear liquid feed (fertilizer), or

• a second pump for a second irrigation network, increasing total capacity from 18 to 36 plants.

Improved Components

• Nine watering levels for finer control

• Updated three-probe water level sensor with alerts for “low” and “empty”

• New DRV3 drippers delivering 1 litre per hour with flow direction arrow and built-in stopper

• Hand control module with LCD display and LED status indicators
