IO 102 SQFlex breaker box
The IO 102 is designed for wind-powered SQFlex systems.
The IO 102 enables the pump in an SQFlex Wind or Combi
system to be manually started and stopped.
The ON/OFF switch has a built-in "electrical brake" for the
turbine. When the switch is in OFF position, the turbine
stops or slows down.
The IO 102 rectifies the three-phase AC voltage from the
wind turbine into DC voltage. Furthermore, it enables the
combination of the wind energy from the wind turbine and
the solar energy from the solar panels.
The IO 102 functions as a box that connects all necessary
cables.

Charge controller
The charge controller is used when a battery backup system
is installed with an SQFlex pumping system. These systems
are typically used in applications where the pump is not
running during most of the peak sun hours of the day, or
where it is impossible or impractical to store large volumes
of water. Examples include remote homes or cabins,
automatic livestock waterers, and very low-yielding wells.
The charge controller is an automatic battery charger, and
the only setting required is the battery-selection.
There are three battery types available:
• gel battery
• sealed battery
• flooded battery.
The charge controller enables manual disconnection of the
pump, the solar modules or both at the same time.
Wind turbine
The wind turbine has a working voltage range of 30 to
maximum 220 VAC, single- or three-phase.
The IO 102 functions as a breaker box and must be
included in SQFlex Wind systems.
Note: The IO 102 must be ordered separately.
Generator
The generator can be either diesel- or gasoline-driven.
The generator must be running steadily before the pump is
started.
