SQFlex Solar with CU 200 and backup
generator
During periods of limited solar energy, the SQFlex Solar
system provides reliable water supply.
The water supply is ensured by a diesel or gasoline
generator connected to the system through the IO 101.
The system switches automatically to operation via
generator when the generator is started.
If the generator is stopped manually or runs out of fuel, the
IO 101 automatically changes back to solar energy.
Benefits
The system ensures water supply during the night or during
periods of insufficient solar energy.
Other benefits:
• easy installation
• maintenance confined to periodic cleaning of the solar
panels
• few and simple components
• flexibility.
Note: CU 200 works with SQFlex up to 1400 W. CIU 903
works with any SQFlex up to 2500 W.
