Quick question...
Hypothetically, when using an EPS box, if you have a grid outage and your batteries go flat overnight, when the sun shines the following day, does the system start up without anything from the grid?

That's a great question.
It's an answer I don't know.

The Inverter does need power to function, open/close relays etc. If the Inverter shuts down at 10% reserve, then you will be stuffed I suspect.
