SQFlex Solar
The SQFlex Solar system is the simplest of the SQFlex
range.
Benefits
The protective circuit incorporated in the motor electronic
unit stops the pump in case of dry running or similar
situations.
By using the IO 50, the power supply to the pump can be
switched off manually, for example in the following cases:
• There is no need for water supply.
• The system requires service.
Other benefits:
• easy installation
• maintenance confined to periodic cleaning of the solar
panels
• few and simple components.
