Is it okay to rest the extension cords (how you get off-grid power to your main I presume) on top of the electric baseboard heater? Looks like a cool man cave. Maybe you don't need the heater with the growatt humming away generating heat? I assume that is a sub-panel, as there is no meter?
Let's try this out. Take a quick picture or 5 of your current battery and system and share it here!
Let's keep all posts focused on pictures only. If you like a system, give it a thumbs up but don't reply!
Let's see if we can pull this off!
