SolarEdge loses “false advertising” case against Enphase due to lack of evidence

Marketing stunt by Enphase leads to a law suit from SolarEdge for unfair product comparison and unlicensed use of a logo.


SolarEdge filed a preliminary injunction against Enphase for using the above video to compare SolarEdge’s String + Standalone Optimizers against Enphase’s Energized AC Module.

The case also states that Enphase used SolarEdge’s logo without permission, citing trademark infringement.



The Energized AC Module from Enphase emerged as the winner at the end of a marked time-lapse in the video.

Enphase claimed that the installers in the video had no prior experience with the Enphase Module and are not employees of Enphase.

Unfortunately for SolarEdge, the Northern District of California denied SolarEdge a preliminary injunction.

District Judge Yvonne Gonzalez Rogers stated SolarEdge had failed to present convincing evidence proving a “false advertising” claim.

This win adds to a great month for Enphase, which had earlier on reported convincing second quarter numbers for its investors.
