I leave mine plugged in all the time it's home and I leave the refrigerator on all the time too
like said before you will need and adapter 30amp to a 20amp
just don't turn your roof AC on or it will trip your house circuit breaker everytime
I even have a radiator type heater in there in the winter to keep the temp at least above freezing.
with no problem . like I said just don't turn the AC or Heatpump on or it will blow the house circuit breaker.
they use a lot of power.
