One small correction regarding the need to drain the unit. The manual mentions that even if you're using it only in cool, you should drain it once at the end if the season. I've only been using mine for about a month and there was quite a bit of water when i drained it.

Thanks for answering the moisture question.

What is the wattage on this portable machine please. Just wondering if I can use my ECO-Flow Solar Generator which is 1800 watts with a 3000 watt power surge.

does this one have temperature sensor?

Also, does it have a "Soft Start"
