The data
Warranty coverage: 10-year term
Coverage includes
Parts & labour · term longer than 9 of 43 scored inverters
No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.
Two things to check
Ask the installer: Will the exact ET G2 model satisfy the site phase, array, MPPT, export-control and local grid requirements?

Strong evidence coverage
