As a landlord, I would not approve of this tomfoolery in any of my buildings.
Safety hazards I see include: Solar panels on the roof that aren’t bolted dow; I don’t care what wind speed they’re rated for. Wires running from them to the inside of the house not in conduit and not secured. A high energy battery pack not NRTL listed. Extension cords draped through the house permanently installed (within the expansive definition of permanently installed used by the NEC)
In addition running the wires in through a cracked window creates an unacceptable risk of water damage.
That said, it’s a cool project. Just do this in a barn you own not a house I own.
