In 2008, the Photovoltaic Equipment Interface Specification task force decided to use SEMI SECS-II (E5), GEM (E30), and HSMS (E37) standards as the foundation for host communication throughout the photovoltaic industry. The result was the new SEMI PV2 standard: the Guide for PV Equipment Communication Interfaces (PVECI). This paper serves as an introduction to PVECI and GEM standard implementation.
- Common quality issues and how to avoid them
- Performance challenges and expectations
- Testing options for a PVECI interface
