The goal of the SunSpec Alliance is to create a common language that renewable energy component manufacturers can use to achieve plug-and-play interoperability between the components and management systems that make up renewable energy power generation systems.
The SunSpec Alliance is now publishing a series of specifications, each consisting of a data model and transport protocol mappings (initially Modbus®, XML and TCP/IP), for each of the component technologies in the system hierarchy (including inverters, panels, string combiners, meters, environmental sensors, trackers, modules, data loggers, and other components).
SunSpec Specifications Available for Public Comment
Several SunSpec specifications are now available for public comment, providing all interested individuals and organizations the opportunity to review and provide feedback on the draft specifications before they are released in final form. Specifications available for download include:
- Common Device Models
- Inverter Models
- Meter Models
- Environmental Models
- String Combiner Models
- Module/Panel Models
- Logger Upload Format and Protocol
Industry stakeholders are encouraged to review the specifications and provide candid feedback by posting to the blog below.
