HOWEVER - it has a known flaw. When it gets cold outside, like 40 degrees or cooler, the heat will not turn on. The fix is you have to relocate the intake temp sensor,to inside your house - then it'll work fine. This is detailed on a few Reddit posts, and is an easy modification to make.
Overall, love these untis, but they will go on sale for $300 for the heat-pump ones if patient - have a few Toshiba ones (rebranded Midea's) myself and they are great!
I posted this deal last time and got it. I haven't used it so can't tell you how it is compared to the midea. I have the midea with heat and it's great so far.

Some modern inverter compressors WITH inverter fans do a much better job verses your normal 100% on or completely off compressor or budget inverter unit with just an inverter compressor but they still hit a wall where they cannot 'recover' enough heat. Darn flawed physics
You are also risking damaging the unit doing that or at least turning it into a block of ice. There is a reason the unit was set to lock out at a certain temp (also controls defrost as well). But that limit might be too conservative for certain applications. If your climate is on the borderline it might be fine. Just don't pitch a fit when the unit dies after 1-2 winters.
By tricking the unit to run endlessly at times it will have no hopes in actually recovering enough heat to ever satisfy the thermostat, you are also dragging down the average efficiency of the unit. That could (and probably will) cause lower efficiency AKA HIGHER POWER USE (even at warmer temps) because the unit is getting false readings on ambient temperatures and could cause extra wear and possible damage to the unit when it is running below rated temps. The entire point of an inverter unit is the compressor is scaled EXACTLY with current conditions...conditions that are now incorrect because of your trinkering.
An analogy would be relocating your car's intake air temp sensor.
This is what a bad / missing / relocated sensor looks like. (other problems can also manifest themselves similarly though)

"SEER issue"....LOL. Yeah, liquid refrigerant entering the compressor is just a "SEER issue."
BTW, I work in HVAC...what do you do? Other than give bad DIY advice gleaned from Reddit.
Reddit easiest for instructions?

"we don't have the efficiency to run it yet"
False, many people run mini splits on solar, a little thing like that 5kw is even easier. Cooling is easy on solar since much of the time when you need cooling you have good sun, heating is harder because that's often in a time of year with little to no sun.
There are also mini splits designed to connect directly to solar to offset their power use,

Sometimes it's just cheaper to use a normal mini split and connect that to a solar battery setup and seperate solar inverter.

So they upgraded efficiency with the inverter technology, and downgraded efficiency with the counterproductive "two pipes in one" technology.
I have an inverter type with 2 separate hoses. I do like the added quietness compared to non-inverter units. It spends a lot of time NOT running full blast, which is a real break my ears appreciate.
...BTW, I'm not recommending this pricey Hisense unit but here's at least an example of a "fully separated" dual hose inverter-equipped unit. https://www.lowes.com/pd/Hisense-...5005522217
Hmm I actually have the 8,000 btu of this and was thinking of getting the midea
