Grundfos SQFlex IO101 AC Interface Box Pump Controller
The IO101 is an interface for using AC backup (115V) on a solar pump. The IO 101 enables the connection of a back-up generator in case of insufficient solar energy. The switching between solar power to generator must be made manually, however, when AC power stops, it automatically reconnects the array to let the sun continue pumping.
(PLEASE NOTE FOR USE WITH 115VAC ONLY)
