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.
people install them in cargo trailer conversions, But I would assume some have them hardwired and an option to boondock off batteries by also having it plugged into an inverter via plug.

I already have 220 pulled for an existing 10 year old Daikan. I'm capable of taking the circuit down to 110 (and arguably could use another free slot in my panel as i'm close to maxing out). The 220 version is $50 more. Any advantages to staying with 220?
no benefit with 220, I would rather have the extra circuit, you need proper wire size though.

I don't know the exact situation but just keep in mind that when you're running 220 that the amps are pretty much split where one leg is carrying half the amps and the other leg is carrying the other half. On 110, One of the wires of carrying all the amps. Just keep it in mind about your wire gauge size for your run.

I have a 10 year old Daikan that was professionally installed. It began leaking about 3 years ago and requires a "top off" once every year or two. That price has risen to $3-500 to have done now.

I'm fairly hands on and thinking of just purchasing and installing a new. CAn you comment on concerns of how the install may affect the unit leaking?
Mine was not installed professionally. I paid less than $500 for installation. The guy did not do a good job on it, and it leaked every 3 months.

That's why I am interested in these budget mini splits that just need to last a couple years. When it becomes a problem, I just find a new one instead of trying to repair it.

I've installed 3 minisplits. This will be my 4th.

If you won't mind it taking an extra 30 to 45 seconds to warm up or cool down, 120V is fine. I've got half on 220 and half on 120. That's basically been the only noticable difference.

I'm running one of my 120v Pioneers on solar via EG4 3000w inverter (this one: https://signaturesolar.com/eg4-3k...v-48-3000w). Works awesome. Really happy with the slow "spin-up" of these so it doesn't overwhelm anything.

easy just run a 120 cord and plug. Main thing is really just know you're circuit a 9000 btu i plug those in uses about 9 amps max at 120v. 12000 btu i'd imagine would use an additional 1/3-1/4th of that. So make sure that circuit isn't overloaded used for other things ,etc. And at those amps i'd not have some hokey back stabbed outlets in the middle of a run. But most of the time they use about 90-500 watts. 1000 watts (in case of 9000 btu) when getting temp down. So it's not like hooking up a non inverter that is constant 1000+ watt load which can create more heat.

Does anybody know the exact model number of this unit? The model numbers shown on the manual that's downloadable show that none of them are energy certified and probably doesn't qualify for the federal credit.

They are not intended to plug into an outlet. They do not come with such a cord, only hardwired terminals. The power needs to be supplied to the outdoor unit and should be at least a 12 gauge dedicated wire with a disconnect. A 20 amp breaker is recommended. That is the intention of the manufacturer and to keep it to code. But would it function if you just plugged it into an outlet with a sufficient patch cord gauge and into an outlet with the required minimum amp capacity? Yes, but not safe or to code.

How hard is it to vacuum the lines? I've installed a BlueRidge DIY system (similar to MRCOOL) myself and it was fairly easy. My utility is offering impressive rebates and I was about to buy a crap ton more of the DIY units but these ones are tempting too.

on 110 the neutral (0V) and hot (+110V) both carry all the current. on 220 there is no neutral so you have 1 hot phase (-110V) and another hot phase (110V) carrying half the current of the 110.

Does anyone know when the code expires? I'm looking at a few options for a mini split.

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.
What is the advantage of 220 vs 110? Does it practically matter? I have a huge house and don't want to pay to condition 90% of it when I'm normally in my room. Is something like this good enough or should you pay more for a "name brand"?

just switch the breaker and you have 110, most likely no need to run a new wire (check the gauge and run length with amps). Each model has the efficiency listed...that is what matters, not 110 vs 220

as long as it's a dedicated outlet that leads to its own breaker
