Your benefit as …
Operators & investors
Real-time monitoring with REFUview
REFUview shows the status, output and yield of your PV plant in real time, on your computer and on your smartphone. Spot deviations early and protect your yield.
Data hosting in Germany
Your plant data is hosted and processed in Germany. This makes data protection and data sovereignty easier, especially for operators of critical infrastructure.
Technical support from Germany
For questions about operation, faults or firmware updates, you can reach our technical support in Germany, personally and without detours.
EPCs & general contractors
Datasheets, certificates and manuals in the download centre
Datasheets, unit certificates, declarations of conformity and manuals are all in one place in the download centre, always in the current version.
Personal contacts in sales and engineering
For system design, quotations and detailed technical questions, you talk directly to our sales team and our engineers, including for large solar parks.
Scalable with REFUlink and REFUview
REFUlink connects up to 60 inverters to the control room and the grid operator, while REFUview brings all operating data together. The system grows with your plant.
Installers & electrical contractors
Easy commissioning
Many models can be set up via app over Bluetooth directly at the inverter. This saves time when commissioning on commercial rooftops.
Technical support from Germany
For questions about installation, settings or error messages, you can reach our technical support in Germany, personally and without detours.
Fits new and existing systems
REFUsol inverters can be integrated into new and existing PV plants, and via REFUlink also together with older generations of REFU inverters.
Planners & engineers
Unit certificates and declarations of conformity in the download centre
Download the evidence you need for plant design, such as unit certificates to VDE-AR-N 4105 and 4110 or EN 50549, directly and without a request.
Complete technical data for comparison
Every product page shows all values from the datasheet, from the MPPT voltage range to the overvoltage category, clearly arranged by group.
Direct contact with engineering
For detailed questions on grid protection, reactive power or plant control, talk directly to our engineers, without detours.
Utilities & grid operators
Power control via Modbus TCP/IP and DRM
With REFUlink, you apply active and reactive power setpoints via Modbus TCP/IP or the DRM levels 0, 30, 60 and 100 % on all connected inverters.
Grid-compliant operation to grid codes
The inverters meet the requirements of EN 50549 and the German VDE application rules for connection to low- and medium-voltage grids, certified and documented.
Data hosting in Germany
Operating data is hosted and processed in Germany. This supports operators of critical infrastructure with data protection and information security.
