SQFlex Solar
- with CU 200 and level switch
The SQFlex Solar system allows solar energy to be
stored as water in a reservoir.
SQFlex Solar water supply systems with a water
reservoir are used where
• there is a need for water supply at night
• for short periods, the solar energy is insufficient to
run the pump
• there is a need for a back-up water source.
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.
In addition, the system features
• easy installation
• maintenance confined to periodic cleaning of
the solar panels.
