Yes, Sun Pumps systems are fully compatible with float switches and other tank level sensors, making it easy to automate water delivery, prevent tank overflow, and protect your solar pump from unnecessary run time.

How Float Switches Work with Sun Pumps

A float switch is installed in your storage tank or trough and wired directly to the Sun Pumps controller. When the tank reaches the desired water level, the float switch signals the controller to shut the pump off. As water is used and the level drops, the pump automatically turns back on when sunlight is available.

This setup is ideal for:

• Livestock watering

• Remote stock tanks

• Irrigation holding tanks

• Off-grid water systems

Compatible Sensor Types

Sun Pumps controllers can work with several common tank monitoring options, including:

• Mechanical float switches

• Electrical float switches

• Low-water cutoff switches

• Multi-level tank sensors (with compatible controllers)

Your specific pump model and controller will determine which sensor type is best.

Benefits of Using a Float Switch with a Solar Pump

• Prevents tank overflow and water waste

• Protects the pump from dry-run conditions

• Extends pump and controller life

• Enables true “set it and forget it” operation

• Reduces maintenance and manual monitoring

Installation Notes

Float switches are typically wired to the controller’s designated sensor terminals. Installation requirements may vary depending on:

• Pump model

• Controller type

• Distance between tank and controller

• Single-tank vs multi-tank setups

For best results, Sun Pumps recommends confirming compatibility before installation.
