SQFlex Combo
- with CU 200 and level switch
The SQFlex Combo system allows solar and wind
energy to be stored as water in a reservoir.
SQFlex Combo water supply systems with a water
reservoir are used where
• for short periods, the solar or wind energy is
insufficient to run the pump
• there is a need for a back-up water source.
As the turbine noise level increases with the wind
speed, installation of the wind turbine near a residence
is not recommended.
Benefits
Combined with the CU 200, the level switch acts as a
pump cut-out function when the water reservoir is full.
The CU 200 offers indication of
• full water reservoir (level switch activated)
• pump operation
• input power.
The CU 200 indicates operational stoppage in case of
• dry running
• service (see page 35)
• insufficient energy supply.
The IO 102 makes it possible to switch off the power
supply in the system and to slow down or stop the wind
turbine when
• there is no need for water supply
• the system requires service.
Other benefits of the system include
• easy installation
• a minimum of maintenance.
