The Grundfos SQFlex system can take DC power straight from the solar panel and be connected to the pump drive motor. The drive motor can handle both AC and DC power supply and the built in motor drive can use these inputs to power the pump. The CU 200 SQFlex Control unit is added to provide a visual display and manual control of the pump.

Sizing of SQFlex system
Grundfos has developed a PC-based sizing tool enabling the sizing of SQFlex systems. The sizing tool is integrated in Grundfos WinCAPS and covers both solar- and wind-powered systems.
The following three parameters must be known for the sizing of the optimum SQFlex system:
• installation location
• maximum head required
• quantity of water required.

CU 200 SQFlex control unit
The CU 200 incorporates cable entries for
• power supply connection
• pump connection
• earth connection
• level switch connection
Communication between the CU 200 and the pump takes place via the pump power supply cable. This is called mains borne signalling (or Power Line Communication),and this principle means that no extra cables between the CU 200 and the pump are required. It is possible to start, stop and reset the pump with the on/off button
The CU 200 offers
• system monitoring
• alarm indication.
The following indications allow the operation
of the pump to be monitored:
• water reservoir is full (level switch)
• pump is running
• input power
The CU 200 offers the following alarm indications:
• Dry running
• Service needed in case of
– no contact to pump
– over voltage
– over temperature
– overload.
In addition, the CU 200 shows the symbols of
the energy supply options.
