Bad, Better, Best: Battery-Inverter Communications & Compatibility
In this article, we compare basic and advanced battery communication, discuss the challenge of ''good'' inverter-battery communication, and what happens when it''s absent, incomplete, or working like a dream. As discussed in the previous article, "closed-loop communication" is a buzzphrase that vaguely describes "communicating batteries."
