Grundfos

SQ Flex The Grundfos SQ Flex pumping systems are a giant leap forward for solar water pumping. Grundfos, the world?s largest pump manufacturer, has reduced the cost of the pumps along with reducing the power needs. The result is a Grundfos centrifugal or helical rotor quality system for about the cost of a diaphragm pump. The Grundfos SQ Flex pumping system can also be powered by certain wind generators if you have the right site.
Features: Up to 390 foot head applications - 30-300 VDC, or 90-240 VAC single-phase AC input. - Permanent magnet high efficiency motor - Overload protection - Over temperature protection - Dry running protection - Maximum Power Point Tracking to optimize pump operation according to DC Power available. - Power line communication with the CU200 (optional use) to display operational conditions.

CU200 - SQFlex Control Box, Solar/Wind Monitor with Float Switch Terminals. This controller and system monitor can be used with solar alone or in combination with the IO 101 (for manual generator backup) and/or the IO102 ( for wind generator ). The CU200 will allow you to add a float switch to shut off the pump when the storage tank is full. The system monitor display on the CU200 shows the following: Pump operation; Full Tank; Input Power ( Watts ); and Alarm Indicator for dry running, overvoltage, overload and over temperature.
