California — Tigo Energy announced that it has reached a settlement with Altenergy Power Systems (“APsystems”) over a lawsuit regarding the infringement of Tigo’s intellectual property by APsystems.



As part of the settlement, APsystems obtain a license to use Tigo’s rapid shutdown technology.

“Ultimately, we believe this arrangement is a win for PV customers everywhere,” stated Zvi Alon, Chairman and CEO of Tigo. “I want to thank APsystems for recognizing our intellectual property and arriving at an outcome that works for all parties involved.”

Tigo endorses the need to provide customers alternative solutions and will cooperate with APsystems to continue the development of leading-edge solutions.

Tigo’s complaint included six patents related to various systems and methods used in the PV module rapid shutdown unit applicable to both the Rapid Shutdown device as well as the Rapid Shutdown transmitter. These are the same patents that Tigo disclosed to the Sunspec Alliance in 2017.
