Good communication with the inverter and easy to fit in the installation. Happy with the result.
David Clarke — United Kingdom -
Straightforward product and good value. It was what we needed for our single-phase setup
Luís Ferreira -
Bought it for a small solar installation at home. It does what we expected and we have had no issues with it.
Jakub Nowak -
We installed it together with the inverter and everything works as expected. A practical solution without unnecessary extras.
