GRUNDFOS Circulator Pump-SQ Flex AC/PV Interface Box

Q Flex AC/PV Interface Box

The IO101 is an interface for using AC backup on a SQ Flex pump being powered solar direct. An automatic transfer switch disconnects the solar array when AC power from a generator, utility connection or inverter is present and is higher voltage than the array voltage. When AC power stops, it automatically reconnects the array to let the sun continue pumping. This unit can be placed before a CU200 to easily select power source used by the CU200 and Flex pump.

**Note: This device is 110-120 VAC only. Will not operate on 240 VAC.**
