Rain Bird ESP9V1SOL ESP-9V Irrigation Controller

Product Description

The RAIN BIRD ESP9V1SOL is a 9-volt battery-operated irrigation controller engineered for underground installation inside a standard valve box. The unit operates on a single 9-volt battery and is built to function normally even when fully submerged in water, making it well-suited for in-ground installation environments where moisture intrusion is expected. Licensed irrigation technicians and landscape contractors install this controller as a self-contained, wire-free solution for single-station drip or spray zone control. The compact form factor fits neatly within a valve box alongside the solenoid valve it drives.

This controller is intended for residential and light commercial landscape irrigation systems where running low-voltage wire from a central controller is impractical or cost-prohibitive. It mounts directly in a valve box underground, eliminating the need for a separate controller enclosure or exterior mounting surface. Typical applications include remote zones, island beds, slopes, and retrofit installations where standalone battery operation is the preferred approach.

Key Features

• Designed for underground installation inside a standard irrigation valve box
• Fully submersible construction allows normal operation when flooded or submerged
• Battery-operated design eliminates the need for low-voltage wire runs to a central controller
• Compact dimensions allow installation alongside the solenoid valve in the same box

Compatibility

Designed as an OEM-style battery-operated controller for single-station residential and light commercial irrigation valve box installations.

Installation Notes

Installation is typically performed by a licensed irrigation technician or qualified landscape contractor. Before servicing or replacing the controller, shut off the water supply to the zone and confirm the battery is removed prior to making any wiring connections to the solenoid valve. Install in accordance with local plumbing and irrigation codes, and ensure the valve box cover seats properly to protect the unit from debris and traffic load.
