Grundfos CU200 SQFlex Pump Controller w/ Level Switch

CU200 SQFlex Pump Controller w/ Level Switch The Grundfos CU200 is the dedicated control unit for the SQFlex pump system, serving as the intelligent brain that manages power input, motor protection, and pump operation across the full range of SQFlex submersible pumps. Designed to accept variable power from solar panels, wind turbines, or AC grid sources, the CU200 continuously monitors incoming voltage and automatically adjusts pump speed to match available power — maximizing energy harvest and ensuring smooth, reliable operation under fluctuating renewable energy conditions. The included level switch adds automatic tank or reservoir management to the system, triggering pump start and stop functions based on water level to prevent overflow and dry-running without any manual intervention. Built for outdoor and off-grid installation environments, the CU200 features a robust, weatherproof enclosure and an intuitive interface for straightforward setup and monitoring. It provides essential protections including dry-run shutdown, overload protection, and fault indication — all critical safeguards for pumps installed in remote locations where service access is limited. Whether managing a solar-powered homestead water system, an agricultural irrigation setup, or a community water supply, the Grundfos CU200 is the essential control component that ties the entire SQFlex system together.
