What does MESA-compliant mean?

The MESA-Device Specification proposes standards for how the different components of an energy storage system (power meters, power conversion systems, and batteries) communicate with one another. The specification is based on previous work from the SunSpec Alliance, extended via a joint development effort between SunSpec and MESA. The specification consists of three components; see below for a description of each component and links to the relevant documentation.

MESA-Device/SunSpec Energy Storage Model builds on SunSpec’s model-based framework. To acquaint yourself with the architectural concepts, start your reading with SunSpec Technology Overview – 12040 and SunSpec Information Model Reference.
