New likely project - solar dedicated mini-split

[MountainGirl]

@gll Ok, I'm confused about something. On this unit -

" GE Profile ClearView Window Air Conditioner 6,100 BTU, WiFi Enabled, Ultra Quiet for Small Rooms, Full Window View with Easy Installation, Energy-Efficient Cooling, 6K Window AC Unit, White https://a.co/d/cPt9ILq "

- the options are between an inverter and a non-inverter unit.

What does the inverter (in this case) do? All I could glean from the two descriptions is the invertor one runs quieter... wha?

Totally my brain fog. I see "inverter" in a description & think Yes! I can power it w/DC. <--if that's not the case here, too bad LOL

Edit: Gll - never mind. Easy rider cleared it up, much to his chagrin.

We're going to have a soft start put on the 3ton central A/C... waiting for the guy to call us back, which he will. He's understandably swamped at the moment -

That's good! I was just stating that because even small air conditioners pull quite a bit of wattage at start up.

Keeping this in the forum also -

I designed/had installed a small system up on the mountain - 3K array, 24v, schneider 2400w inverter, literal ton of rolls surrette lead acid batts - all installed 2016. LOTS of improvements in the solar game since then...and the next time I use a lead-acid will be never.

It might be that 'solar mini split' is a misleading term for what I want to do.

The only one I've found so far (on youtube) is an E04 or something like that, that "runs" on ac or dc - but it's solar (dc) in the sunny daytime, then back on ac for cloudy/overnights - and that isn't really what I was thinking.

I'd like a split that can run on dc all the time. If no such puppy exists - I might go with a dc window air... if those exist. LOL And if they dont - I'll keep thinking.

The room size is 18x18

Please keep us informed, sounds great

That they do.
I've pretty much resigned to having to have an inverter, so I'm keeping the surge numbers in mind.

inverter type A/C have a variable speed compressor.

What is the Difference Between Inverter and Non-Inverter AC?

Inverter and non-inverter ACs are two different kinds of air conditioners that have their own pros and cons. Wanna know which is right for you? Read more.

Well hell. They should have named it something else so those of us who get all excited about Direct Current don't go off all half-cocked!!!
Whadda bunch of inconsiderate bozo's.


(And thanks! LOL )

I was under the impression that vac powered mini splits and vac powered ac’s with inverters were to enable them to use a variable speed VDC compressor, which is apparently more efficient than the VAC compressors.

You might double check me, but I think that is correct.

What is the Difference Between Inverter and Non-Inverter AC?

Inverter and non-inverter ACs are two different kinds of air conditioners that have their own pros and cons. Wanna know which is right for you? Read more.

www.tcl.com

“An inverter air conditioner is a type of air conditioning unit that can adjust the compressor's motor speed to regulate the temperature. The use of an inverter switch allows for greater flexibility in terms of power usage. Inverter ACs are more energy efficient than non-inverters because they can change their power consumption depending on how hot it is outside, or if you have multiple people in your home at any given time.



The inverter is connected to a number of other components including the battery and solar panel, which are used to power the system. It also receives information from sensors that monitor the health of your batteries and solar panels, so it can make sure they’re functioning correctly. Inverters are responsible for managing the flow of power between your home’s electricity grid and your battery bank or solar panels.”

And they all still plug right in to the (alternating current) wall outlet (including the "DC" units on the TCL link.

Thanks for the info.

We need to greatly reinforce the beams and floor joists under his armory study.

Maybe something like this, intended for trucks or RVs...

NEKPOKKA 12V DC air conditioner，electric air conditioning unit are applicable to trucks, RVs, buses, agricultural vehicles, campers, etc. 12V split electric air conditioner (12V) https://a.co/d/4e2AAH9

Not this one necessarily, but just the idea that 12v is used more in trucks and RVs and that's where to look.

Thanks, that's where I've been looking.
I doubt I'll have any difficulty finding the right appliance - it's the 'powering it overnight' without an engine running (even with DC) that's the challenging part. I've got time, now, to really research/think on it. It'll come.

 

[gll]

When you think you've found it, bring it back here so we can shoot holes in it...

...cause that's the kinda thing we like to do!

Oh I will - and that's what I'd want!
Fails are much easier to prevent before it goes from paper to project.

Found this vid -





and exploring Zamna further - I found this. DC system.

Okay @gll - do your thing.

That looks like just the ticket!
