Grundfos SQFlex Pump Generator Interface Box (IO 101)
The IO 101 is designed specifically for solar-powered Grundfos SQFlex pump systems. The IO 101 enables the connection of a backup generator in case of insufficient solar energy from the PV panels. The switching between solar power and generator must be made manually. However, when the generator is stopped or runs out of fuel, the IO 101 will automatically switch back to the solar panels. The IO 101 functions as a connection box joining all necessary cables.
Unlike the CU 200 SQFlex Pump Controller, the IO 101 does not contain float switch terminals.
