Based on the specs, it will pull 9 amps. These things sip electricity.

Could you terminate to a plug? Yes. Should you? Probably not. Feels like that would not meet code, but I can't confirm that. Just sounds suspect.

That said, I have a Costway 18K BTU mini split in my 1,000 sqft shop with very little insulation. It works well, but it isn't but enough for the shop. I knew that putting it in. I paid $589 about a year ago, but no WiFi on mine. 220 volt

I installed it, and consider myself slightly above novice. I know enough to be dangerous. Plenty of online videos. Only odd tool you need is an HVAC vacuum. Otherwise all the tools you need you probably already have.

Instructions are detailed good. The only issue I had was really around the electrical wiring . The wire colors on the unit did not match the instructions, so it took me a bit to figure it out.
You are charged for the *power* (watts) you use, not the amps..

--

Power = Current x Voltage

110v x 10 amps = 1100 watts.

220v x 5 amps = 1100 watts.
Get an electrician to install a generator inlet on your breaker panel and use the f3800 plugged into it.

I did that with mine when I only had 1 f3800. I ran a test on the hottest day of the year last year and kept the f3800 topped up using my ev's v2l and a dc power supply. I was mostly able to run the whole house including 1 3.5 ton hvac with soft start (I have 2) running at a time for 8 hours.

I now have 2 f3800s and the double power hub.

> heat even at -15℉ and cool even at 126℉

This is amazing. I'm debating between this higher-priced one versus the Yitahome in the other thread. The Yitahome can only do 5°F to 118°F. But.. the temperature has not gone lower than that here in Houston. Decision, decision...

Can these 110V units be plugged into a wall outlet or must they be hardwired? I'm looking for a heat pump that I can run from my Anker F3800 "portable" battery + solar panels in case of a power outage.

I don't see why you can't terminate the wiring with a plug

The problem is probably the power pull of these. Will work fine if it is the only thing on the circuit but expect to trip breaker often if you have other things on the circuit. That is why appliances like these need their own dedicated circuits.

I have bought and installed this unit. Super easy to do and having 120 is great if you have a lower amp service or not a a lot of room in your box.

I don't think you actually know how little power these things pull, just a hunch and i don't know if this is an inverter unit, but that would have no initial over-pull so to say.

How diy friendly is this with no knowledge of HVAC or electrical at all?

Anyone has experience with costway vs pioneer vs tosot? I'm researching which of the three brands is better as they're about the same price and either made by gree or aux

which would you recommend?

No 3 stage heat pump can operate below -5f - it's a basic law of thermodynamics.

If 4 stage maybe. But that requires a electric condenser heater - which will cost a fortune to use.
