It’s also illegal and unsafe to plug a generator into a wall outlet with a suicide cord. There’s a reason they’re called “suicide cords”, there’s a reason cable genders are the way they are, the load end of a suicide cord will have hot exposed prongs, which is hella dangerous.

Plugging in a generator like that is probably going to be done during a power outage, so yeah it makes sense to throw the main breaker, even if you are doing something dramatically stupid. That’s if you remember to do it. These balcony panels are meant to generate a small amount of power to lessen your electric bill. You’re not going to power your entire house with a couple hundred watt solar panel. So you’re gonna have the main breaker on.

That’s actually another reason why it needs to be a non grid-forming inverter; because it’ll provide power to a male plug it’s gonna need to prevent users from being shocked while it’s in the sun and unplugged.
