Application examples
SQFlex Combo
- with CU 200 and level switch
The SQFlex Combi system allows solar and wind
energy to be stored as water in a reservoir.
SQFlex Combi water supply systems with a water
reservoir are used where ...
• for short periods, the solar or wind energy is insuffi-
cient to run the pump
• there is a need for a back-up water source.
As the turbine noise level increases with the wind
speed, siting 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.
