What is MESA/SunSpec?

Traditionally, grid energy storage systems (ESS) have been one-off solutions, utilizing proprietary software and hardware components.  As such, each installation requires time consuming, custom integration.  Often times proprietary vendor hardware or software protocols require “hacks” to get all components to play nice.  Ultimately this approach results in higher costs, decreased reliability, and limited scalability and […]
