Higher yields / Safe & Reliable / Smart / User-friendly

SUN 12/14/16K-SG, a hybrid inverter, is suitable for residential and light commercial use, maximizing the self-consumption rate of solar energy and increasing your energy impendence.   During the day, the PV system generates electricity which will be provided to the loads initially. Then, the excess energy will charge the battery via SUN 12/14/16K-SG. Finally, the stored energy can be released when the loads require it. The battery can also be charged by the diesel generator to ensure uninterrupted supply in the event of grid blackout.

It is equipped with an RS485 / CAN port for battery communication.

Technical Specifications

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.
