This is probably a dumb newbie question but I cant find the answer!
1. What does this icon represent? Given the various examples I've seen, I am guessing it represents an 'ESS' and all the kit that comprises the ESS (for example in my 3ph system - 3 multi IIs and a Cerbo GX)?
2. What does External control mean? I've found a few references to the phrase but none make sense (unless somehow it is someone logged into the portal and controlling it that way)?
Answers most welcome!
thanks.
