SQFlex

SQFlex Solar

- with generator as power supply back-up

During periods of limited solar energy, the SQFlex
Solar water supply system provides a safe supply of
water. The system is connected to an external gener-
ator as back-up via the IO 101 switch box.

The system enables operation ...

• via generator when ...

- the energy supply from the solar panels is 

insufficient

• via solar energy when ...

- the generator is stopped manually
- the generator runs out of fuel.

Benefits

• Offers water supply at night or when the solar

energy is insufficient

• Easy to install

• Maintenance confined to periodic cleaning of the

solar panels

• Few and simple components

• Flexible in terms of energy supply.
