How long will a 100 amp hour battery run a 5000 BTU air conditioner?

[@SeidelRanch]

I hooked up this 5000 BTU window unit AC to some 100 amp hour LiFePO4 batteries to see how long it will run. Check out if it even worked and for how long. Check out the batteries here: amzn.to/4dqVaWh

Now get a 12v super capacitor bank and try it with one battery , get the best of both worlds.

[@TheWickerShireProject]

We run off grid at 48v ( 56.7V full 46.2V empty ) with 13.5 Kw Hrs of 15.3 Kw Hrs.

[@MikeLangton-y8b]

I have a Midea window unit with soft start tech. Works great on A 2000 w inverter Works for 1 to 1.5 hrs

[@johnwarner4809]

The capacity of the battery is 100 Amp-Hours x 12.8 Volts = 1,280 Watt-Hours. If the Air Conditioner pulls 500 Watts average-continuous at 120 volts, then 1,280 Watt-Hours/500 Watts = 2.56 hours. Realistically however, the unit will only run for a little over 2 hours, because when the battery gets really low, it won't be able to handle the 20 seconds of surge current every time the compressor turns on (that is, if the compressor cycles). If you add a huge capacitor to accommodate the 20-second compressor start-up surges (the cap fills up between compressor starts, and is there to assist with surge current when the compressor re-starts), then things might run a tad longer. But based on the calculations, I'd say 2.2 hours is about the maximum limit you should expect.

[@SeidelRanch]

Great info. I think that is basically what a soft start does, but they are more than the AC unit is so they are hard to justify for something like this. I have been thinking about putting them on the ACs in my RV, but I have enough battery and solar power so I am not sure it's even worth it. Thanks for the comment.

[@peteralvarez3039]

theoretically, it can run 2.56 hours but that is when the battery is complyely drained. lipo batts should only be drained up to 50%, so you can only run to 1.8 hrs.

[@budmartin3344]

You also have to factor in the inverter conversion loss, typical inverter has about 85 ~ 90% efficiency, so to if 500W is being from from the output of the inverter, then the DC input power that the inverter will be pulling from the batteries is about 555W (@90% eff) this is the number you will be using to get more accurate run time from your battery.

[@louf7178]

@@peteralvarez3039 I believe 50% SOC applies to lead-acid batteries; 10% SOC for LiFePO4.

I would say that the AC would get 2 hours of RUN time. Once the room is cooled to set temp, the AC will shut down.

Back in 2022 the smallest Inverter AC I could find was the LG LW8022IVSM 8k BTU Dual Inverter. On lowest fan speed, it never uses more than 500 watts. LG now offers the LW6023IVSM 6k BTU. I'm keeping my 8k unit: It is quiet enough to sleep with it running, as it gradually ramps the compressor up & down.

[@Mike-01234]

I have 5000 BTU Frigidaire in my shed I'm in Phoenix wanted to keep it at 85 or 90 but highest it would go was 85. We keep stock for our eBay business in there. My first attempt was two 250 watt used solar panels Epever charge controller 12V 100AH lithium battery and 1500 watt inverter. When I first got it the temp outside was about 85F to 90F it would run 8 hours the AC unit pulled about 400 watts. When it got to 115F outside now the window AC was pulling 1000 watts of power. Yes lot more power when it's that hot out I can run about 4-5 hours if panels have full sun which is from about 8am to 1pm neighbor tree shades one panel. My Epever puts out about 29 amps at 12V into the battery but the window AC is pulling 800-1000 watts of power by 10am. It runs longer then I thought it would. Now I'm building version 2 which is 4800 watts of solar, EG4-6000XP AIO inverter, 15k watt 280ah DIY 48V battery pack. It's going in the garage instead of the shed. Working on a mini split for the garage just about done ill start on the panels. Until then I have to swap the AC over to grid power using a long extension cable from the house. The window unit runs 24/7 for weeks and weeks from June-September I'm surprised how long it has held up some times when I shut it down to move the plug over I can hear the refrigerant boiling. If it dies replace it with another one I don't think it will die only cost me $139 at Home Depot.

Great info, thanks. I know what you mean on the temps and wattage. Mine has held up fine for over 10 years and used for probably 9 months of the year.

I plan to repeat the test with my pure sine wave inverter and do not expect any problems. Good topic and video.

Interesting test. I will say if I was trying to run ac off solar/ batteries I would spring for a inverter driven mini split. They are light years ahead of a window unit. Not only get rid of the surge but also get about twice the cooling for the energy expended. So an 8000btu mini split will take less power to run than a 5000btu window unit. Your wording suggests you think that setting the thermostat lower will make it cool faster. The thermostat is just a switch. If the temperature is above setpoint the unit is on. A lot of people seem to think setting the thermostat lower will make the ac cool faster even you don't so thought it was worth mentioning. SEER rating =btus of heat removed per wh. Most mini splits are around 21. That window unit is around 9.75 seer . So burns more than twice the energy to do the same job

[@SeidelRanch]

I have a mini split, but not an inverter mini split. The mini split is WAY better than the window unit, but it's still working so I don't want to toss it. I set it lower to make sure the compressor would at least cycle on for the test. In this case it never stopped. It's not going to cool "faster", but it will keep it cooling and not cycling over and over.

Pretty close.

[@Jpilgrim30]

That 5,000 BTU unit should pull a little over 1,000 watts at start up and it surely isn’t pulling more than 2,000.

[@allenhoward178]

To stop the surging problem you just install a capacitor

[@JonDoe-cg4mr]

Turn rhe fan on first. Lowers the surge

Doesn't everyone like to hear my voice? I think you should watch it again to make sure.

[@onduhrhoads]

Midea, you're welcome

[@SeidelRanch]

Yeah, I want one but this AC will not die. It just keeps going and going. I want a new inverter window unit.

[@arvidlystnur4827]

So whats the point of this experiment the wattage lost when using a battery is always lower than the wattage used to recharge the battery! And even more energy is lost to generate the charge thus it's more efficient to run high amperage equipment off of a generator. I have a remote cabin that I run lites and radio, 120 ah lead acid battery to a 120 ac inverter. I turn the inverter on about 6:00 pm till about 8:00 am. Each lite draws about 14 watts, radio 5, cd player 15 and bass amp 35 or 40 watts. If I go three days without charging, the inverter might shutdown and charging might take about 2.5 hours to charge using much gasoline. (I have a special charger that can charge a deep cycle battery as fast as possible without excessive plate degradation.) If I go three or two days before charging I've discovered the battery degrades quicker and wears out quicker. By charging it once aday, charging time takes between an hour to twenty minutes. My new ritual is to practice the bass while the generator is charging the batteries, so the amp and cabin are electrified by the generator while charging. Don't tell me about solar cells. The thousands of dollars to match the amperage isn't practical at a remote cabin. A hundred dollar solar bank from harbor freight we bought will charge a battery maybe in about ten hours, IF you keep angling the panels to the sun, WHEN there's sun.

[@SeidelRanch]

We mix both. This was just a test to answer some questions about battery capacity and AC unit load. We also have an off grid cabin in the mountains of CO where there is no electric lines for miles. I use solar panels, wind power and multiple gas generators there. They all have a purpose. We did start with the generators because they were the cheapest to get going and produce the most reliable energy. We added solar and recently a wind turbine to cut down on the noise and gas usage. It's a balance.

[@arvidlystnur4827]

@@SeidelRanch , Thanks for your response. Perhaps I wasn't quite gracious in my comment. I might consider additional power sources other than gas generators in the future.

[@brucesamuelson7541]

Do the math: A 100ah battery is 1.25kw minus 10% loss through the inverter. The ac pulls 500 watts so a little over 2 hours. Class dismissed!😅

[@PatricksDIY]

You should research terms and subject matter more before making a video like this. Almost 80% of what you try to say or explain is incorrect. also the title should be changed to a pair of 100ah

[@sladesmith6377]

He should also mention the fact that they're LiFePO4 in the title

[@SeidelRanch]

Can you explain what you mean? I am always open to learning from those more knowledgeable than myself. The point of the title is that you probably can't run an AC off of a 100ah battery unless it's one of the few that can peak over 250-300 amps.

[@sladesmith6377]

@@SeidelRanch you shouldn't be running over 0.2C if you care about the health of batteries. Start from watts and work backwards. At 500W you would want at least a 2500Wh bank to be able to run this. None of this basic knowledge was mentioned in the video, you just said "it's at about 0.2C" but didn't explain what that means in lamens terms

[@SeidelRanch]

@@sladesmith6377 Thanks. I tired to cover as much as I could without making a 2 hour video. There will always be things to pick at on anything. To my defence though, it was about how long would a small ac unit run on 100ah and not what's the best way to run this and how many batteries do you really need to do it best. Personally I would want way more batteries if I was going to run this ac all the time on battery. I have over 15 KWh of battery capacity in my RV now and I still want to double that just for a 1000 - 1500 watt average load.

[@sladesmith6377]

@@SeidelRanch well the title is click bait nonetheless. That's ultimately where my problem stemmed from

[@MicMaine]

2.4kwh is great, you dont wanna run the batteries down to 0% and damage them

[@RodThibault-qe4hu]

You should of ran the inverter with positive lead on one battery and negative on the other battery

[@SeidelRanch]

Yeah, putting them in parallel would have probably helped but I was not thinking at the time. I wanted to show what one battery did on this unit.

[@Mprikiman]

You can resolve the surge with high power capacitors in parallel with the battery. Just sayin'...

[@SeidelRanch]

I plan on trying that soon. Keep an eye on the channel for that video.

[@WillKlaver]

.. i have never seen a small ac unit Surge to Four Thousand, running Full Bore they only use 400 Watts or so .. more like Six Hundred at most ..

[@SeidelRanch]

Running, yes. It will run well below 1000 watts. Compressor start up though gets in the 2000-3000 watts range on this AC. Others I have are close but lower, some more like 1500 watts.

[@WillKlaver]

@@SeidelRanch .. no it won't, but Whatever .. 🙄🚫

[@The0ldg0at]

Why don't you just put a supercapacitor in parallel with the battery to take care of the surges?

[@SeidelRanch]

I don't have one, but want to get one and try that. I hear those really help take the heavy draw off of the batteries and help them last longer. Looking for a good one now.

[@darkdodger137]

Couldn't you just put the appropriate sized inverter between the single battery and the a/c?

[@SeidelRanch]

The inverter in this test was more than enough to run it.

[@woodennichols100]

Volts times amps equals watts

what size inverter?

[@SeidelRanch]

This one was a 12v 2000 watt pure sine wave inverter.

[@vinniemon-i5h]

If you had a 1000 watts of solar you could run it and charge the battery

[@SeidelRanch]

That is true, if the sun is good. We have solar on the RV and I can run the AC units and still charge the batteries if the sun is nice and clear.

[@HutchinsonJC]

Based on title alone, I don't know... is it a 12v battery, 24v, 48v? Because Voltage * AmpHours = WattHours. Amps by itself tells us nothing.

[@SeidelRanch]

Ah, yeah. I can add that.

[@MicMaine]

He literally says... "13.9 resting voltage" yall just love to critique everything 😅

[@HutchinsonJC]

@@MicMaine The way he titled his video can not be answered without the voltage making the question pointless as a title of a video in the context of what a viewer needs to know to decide if the video is relevant for them and their diy projects. You can call it critiquing everything or maybe the more sane explanation is purely mathematical in that Volts * Amps = Watts and Volts * Amphours = Watthours. Kind of hard to argue the math. A 12v 100amphour battery has 1200 watthours of power in it. You could give some wiggle room from this figure depending on the exact chemistry of battery being used and how many cells are in series of that chemistry. Often anything 11 to 14v is considered a 12v system, give or take. a 48v 100amphour battery has 4800 watthours of power in it. It will run any load the 12v battery above will run, assuming the appropriate inverter is used, roughly 4x longer while requiring thinner copper cabling/wire to do the job. A 4x difference that a potential viewer can't ascertain by the way the video is titled.

[@MicMaine]

@HutchinsonJC so now every creator has to include every detail in the title??! 🤣🤣😅😅 when you watch it, he goes further in depth. This solar and battery community is weird cause all yall seem to do is nitpick at everyone's work and how they got it done

in the trade they're called "window shakers." also, 200 is not 100 like the title shows.

True, but the intent was to try and do it with 100, but it would not work on this one. I am going to try it again with a better setup and see if I can get 1 battery to do it.

[@garyweber7139]

Keep in mind Haier is a Chinese product, I really doubt that you're getting 5,000 btu. It's most likely 3,500 btu or so. Chinese made batteries also seldom produce the amp hours they claim, sometimes dramatically less.
