[RE-wrenches] Code compliant PV wire to an EcoFlow DELTA Pro Ultra Inverter/Charger

[Jason Szumlanski]

That's not where the problems end. It doesn't have arc fault protection. I

buy these portable units and think we can just slap a couple of panels on
the roof, and they're good to go. That's how the marketing makes it sound.
