The HUB system communications manager is the backbone of your networked OutBack power conversion system. The OutBack HUB communicates stacking; load share and power save on/off signals. Interconnection cabling is standard Ethernet CAT5 with RJ45 modular jacks. Through the use of a HUB, your system is completely coordinated and managed by the MATE.

CU 202 is designed for monitoring and controlling SQFlex submersible pumps in solar applications.

The simple user interface and built-in Bluetooth module ensure easy installation and configuration. The Bluetooth connection to the Grundfos GO app offers extensive setup and monitoring options.

CU 202 is pre-configured for tank filling, the most used application, offering a plug-and-pump solution, which saves time on commissioning. For other applications, the controller provides several control modes, which can be easily selected and set through the Grundfos GO app. Grundfos GO makes the configuration easier and allows installers to set up high-performing systems.

CU 202 communicates with the pump through the power cable. This communication principle is called mains borne signaling or powerline communication and means that no additional cables are required to the pump.

Grundfos GO offers detailed information and logs that help the installer to find the root cause in failure situations. In addition, the controller can use Wi-Fi, GENIbus, or Modbus to monitor the system remotely either through Grundfos Connect or another SCADA system. Remote monitoring saves time when inspecting installations.

CU 202 is equipped with power and pump connections and offers 2 configurable inputs and outputs. Additionally, a backup battery can be added to the controller to maintain communication and measurements when solar power is insufficient.

The display of the controller shows:

The pump can be turned on and off through the display of the controller. The controller can display a read-out of the application-related data. It is also possible to adjust the setpoint. The LEDs on the display of the controller can be set to sleep mode, for example, to avoid attracting wildlife.

The following logs are available through Grundfos GO or remote monitoring:

CU 202 indicates warnings and alarms on the display of the controller. Additionally, the Grundfos GO app provides further information on these events including the recommended solutions.
