Australia’s vast and varied landscape presents unique challenges for water supply, especially in remote and rural areas.
For farmers and residents in these regions, accessing timely and accurate information from their water systems can be difficult. Grundfos is addressing this challenge head-on with the CU 202, a next-generation control unit designed to simplify and enhance off-grid water management.
Smart, Solar-Ready, and Seamlessly Connected
The CU 202 is purpose-built for SQFlex submersible pumps in solar-powered applications. It combines status monitoring, control, and communication in one compact unit. With plug-and-play simplicity, users can get up and running quickly - no complex setup required.
What sets the CU 202 apart is its remote connectivity. Whether through Bluetooth® GO Remote or Wi-Fi, customers can monitor and control their systems from anywhere. This means fewer site visits, faster troubleshooting, and more efficient operations.
Grundfos’ SQFlex pumps are renewable energy submersible pumps with built-in inverters that support solar, wind, and AC power sources, making them ideal for Australia’s increasingly unpredictable climate, where dry seasons are getting drier and wet seasons wetter.
Dubbed the “next generation of control units,” the CU 202 is ideal for solar-powered, off-grid water supply solutions. It’s preconfigured for plug-and-pump operation, making it simple and intuitive to use.
Flexible Connections and Real-Time Insights
The CU 202 includes a host of cable entry options for the connection of: power supply connection, pump connection, earth connection and level switch connection.
Grundfos customer, Craig Woods from CQ Pump, says: “We love the CU 202 controller at CQ Pumps, and we've stocked up on a fair few for the busy summer season. Being a rural dealer in Queensland with remote customers, one of the standout features is the customers' ability to download and send us reports without the need for us to go to the site for fault finding."
Adding: “Plus, thinking ahead, the Bluetooth capability means that I can easily download any upcoming features without setting foot on-site. It's a real time-saver."

Built for Simplicity, Designed for Control
The communication between the CU 202 and the pump takes place via the pump power supply cable, which is called mains borne signalling. This also means that no extra cables between the CU 202 and the pumps are required. It is also possible to start, stop and reset the pump, by using the on/off button and the CU 202 control unit also offers system monitoring and alarm indication.
“We have really focused on true versatility when it comes to this control unit. It is very simple and easy to install and can be quickly set up for use. It also allows the user to know what’s going on 24/7 as they can monitor from it remotely,” says Jurgen Mrozek, Senior Regional Product Manager at Grundfos.
The CU 202 also has the following indications which then allow the operation of the pump to be monitored, including when water reservoir is full (with a level switch), when the pump is running and the power is being used.
The CU 202 offers a number of alarm indications such as dry running, to indicate when a service is needed, no contact to pump, overvoltage, overtemperature, overload, and if there is insufficient energy supply.
“By combining technology, efficiency, and real-world capability, we’ve made a reliable workhorse that supports daily water security,” says Mr Mrozek.
