The SQFlex Solar system allows energy from the sun to
be stored as water in a reservoir.
SQFlex Solar water supply systems with a water reser-
voir are used where ...
• there is a need for night-time water supply
• 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.
CU 200 offers indication of ...
• full water reservoir (level switch activated)
• pump operation
• input power.
CU 200 indicates operational stoppage in case of ...
• dry running
• service (see page 18)
• insufficient energy supply.
In addition, the system features ...
• easy installation
• maintenance confined to periodic cleaning of the
solar panels.
