IO 101 SQFlex switch box
The IO 101 is designed for solar-powered SQFlex systems.
The IO 101 enables the connection of a backup generator in
case of insufficient solar energy. The switching between
solar power and generator must be made manually.
If the generator is stopped manually or runs out of fuel, the
IO 101 automatically changes back to solar.
The IO 101 functions as a box that connects all necessary
cables.
