How Many Watts!? EG4 Solar Hybrid Mini Split Ac - Minimum Operating Wattage

This is a video to address some very common questions I get - What's the lowest wattage it can run at? Does it run on cloudy days? Does it need to be reset after it shuts down due to low power? I address all of these questions in this video.

I've been looking at this playlist and I started at your 1 year video for the EG4. I'm doing a "skoolie" build and I think this would be a fantastic solution to my cooling needs over a traditional mini split. I hope you see this because I would love your input on what you would say the Minimum amount of Wattage would recommend dedicating to the EG4. I'm going to dedicate a percentage of my panels for the EG4 then the rest for my battery bank. love your vids you've got a new loyal subscriber now!

[@SmitHVAC.]

I'd give it at least 1200 and try to be over 150vdc

I installed a 9k pioneer last summer here in my '28 RV. They are super efficient on power and whisper quiet.. There inverter type mini splits were just coming out but expensive as well. I'm saving to buy some land and go offgrid.. looks like I'll be replacing it. After the fact, I want a 12k upgrade.. so it'll work out.

It would be a great video if you did the same exact test but using the Heat and the power station again LOL

[@verohandymike]

I can't afford one right now, but this explanation is what makes me want to buy one, and I will soon. I am off grid in Jamaica and have a little window unit that does OK with the setup I have, but it does require a lot of manual adjustments for me. I will wait until the SOC is at 100%, usually around 11am, then turn it on. Typically when the day is sunny I can go until 4-5PM and still be 100%, then I either turn it off or make up my mind to run on battery into the night. I think I'll get this EG4 mini split and have it run independent of the system I have now, even if I have to get it's own battery, just so I really can run it without any concern about it pulling from my current setup. A big bonus is how low watts it will run at, in sunny Jamaica I see no problem using this unit.

Thank you for this wonderful video on the EG4 Hybrid A/C. I purchased the 12000 BTU but have not set it up yet. Still need to purchase the solar panels. Which is my question. I had listened to another youtuber introduce this almost two years ago and he stated that he had x4 400 watt solar panels and that you would need at least that much to run it during the day with no problem. Would you say that is about correct with your experience where you are? The math equation when calculating solar and the technical jargon are not my specialty. You demonstrated that 140 watts coming in would be the bare minimum? How does that translate to what I would need in regards to solar panels? The x4 400 watt minimum? Thanks again.

[@SmitHVAC.]

4 x 400w is the perfect number for best efficiency, you can get away with less but most people like to connect the maximum allowable solar so it can run better in poor sun conditions

[@siarlbychan]

Does the unit need a dedicated solar panel? Or can the panel also be connected to your battery bank at the same time?

Dedicated. You might be able to connect it to both of you got creative..

Could i expect the same results with 12k btu 28.5 seer unit? I have a ac 200 L power station that i hope to run with mine, i have 1100 watts of solar on the roof of my bus but so far i have only seen a max of 500 watts.. my yard is tree heavy with shade. What watt does eco mode normally run on the eg4?

[@SmitHVAC.]

Should be pretty close. Is it 120v? Eco mode runs around 300w on heat and even less in cooling mode.

[@HotGritz910]

@SmitHVAC. yes, 120v 30 amp AC. I have (4) 20 amp ac plugs and one rv 30 amp plug. Im going to run the eg4 from one of those plugs with a 20 amp circuit breaker.

[@RobertSchmitt-u7l]

There has been little to NO power savings/efficiency gains for 99.5 percent of all window units or small ac systems since the 1940's How can that be? They say theres 25 percent savings, but no, btu per watt is just about the same, or 1-200 watts less when running the full load of a say 15000btu window or mini split unit (which you can state, they work exactly the same. Efficeincy differences are ONLY from heat radiated inside of the physical metal parts and seals and insulation from the outside of the window unit) What window units of decent cooling capacity draw A reasonable 700-800 watts??? These compressors get hot as hell, they should not be exposed to heat because the copper windings will increase resistance, lower efficency, then get hot again and lower efficeincy again because of getting hot. There are hot gasses in the compressor, yes, from the heat cycle of the refrigerant. But the motor should be ambient. Not 150c. The fans too on the units are pigs, the window units expecially. Mini splits might have good to very good efficeincy, if they are dc fans but then they need some stupid, gonna burn out in 10 yr controller) I know these controllers are cheap and built to break. The engineering departments add complexity unessesary and then they break because one crappy part. And then theyre obsolete and non repairable because its an exclusive part or the part is not accessible to, ort the boards straight up fail and take out all the rest of the parts inline so , basically i can prove that they are junk AND I will DEFUND. THe fans should not get hot either, low efficeincy run of the mill units have crappy syncrohnous ac motors with the capacitors that always fail, why do they heat up, and heat up again too from being hot. Copper is only efficeinty in a motor IF IT SAYS COOL!!! THe things use 1200 watts 15k units will mostly all at best take 1200 watts. The things could be using 50 watts for the fan and 700 watts for the compressor. THis means, cop of 5 or 6 or more, Theoretically its like ten, BUT why are they barely scarping by with 3?>?? It should be called energy efficient only if the motors arent running BOILING HOT 100c 150c they are terrible. They are the worst. 1940s, they had the same shit. GOD DAMN!!!1

At night 11PM it is still 95, so then okay great, i got solar splits for the day but how in the world do i keep them going at night time as well. One thing I am wondering about is how long are these things supposed to last?

I just got a 6000xp to run my 2 minisplits through the night, it's a little pricey but it's an amazing system.

[@extendedp1]

Thanks for the video. Would one of these work for a walk in insulated cooler room or root cellar to store food? People make those with window AC’s, they trick the temp sensor so it runs constantly, getting the room colder than designed. I guess you would need to start with an AC that can put out 40F air to start with though. Thanks

I've seen a few people hook the coolbots up to minisplits, definitely more common on the window AC's but this would work.

Thank you so much for this video. Been watching some videos about combo/solar mini splits and I wondered how little of solar panel it would be possible to get by on for some occasional solar cooling and heating. So this means you could run this off 4 cheap 100W panels from Harbor Freight or Amazon then, huh? Can you please repeat this video in the winter and see approximately how many minimum watts are needed to heat? Thanks! I’m wondering/hoping that I can some day out 4 100W panels on the roof of a 7x7 resin shed to power one of these mini splits on solar only for portions of days. Wish they made a 9k BTU version that would use even less power to make this even more likely to be possible for me.

[@SmitHVAC.]

Thanks for watching! I can definitely repeat this in the winter, it does use quite a bit more power in heating mode. You could get away with some cheaper panels but make sure the voltage is high enough, it needs a minimum of 90V DC

[@kameljoe21]

Most people have said that around 1000 watts is the best to have with these units at the highest voltage that the spec sheet said. The most solar if I recall was around 3k and 300 volts or something like that.

For L,N wiring. can you link what you used? To power it through AC power. L,N means live (hot) and N (neutral), correct? I am not asking about the gauge, but rather the cabling.

Technically it should be Nmw 14G for outdoor use but yes, L is line voltage, N is neutral

[@bearupfarm1818]

Hi Smith, I just wanted to ask if the 12K is as good as the 24K? Do they both run the same power consumption or does the 12k run more. I was just trying to get some information. I’m totally off grid with 48volt system. Thanks for your input.

[@SmitHVAC.]

They are almost identical but the 24k has twice the capacity of the 12k. It would use about double the power, just depends how big the space is that your trying to heat or cool.

[@bearupfarm1818]

Ok thanks.

[@ryanyoder7573]

12k runs on 120v 24k requires 240v split phase

[@mikemotorbike4283]

9k most efficient, decreasing efficiency the higher you go, and adding extra heads decreases efficiency of a unit. I wonder if there are there are greater losses running two units over one with two heads. With two separate smaller units you get redundancy, ease of installation and repair. Adding more complexity to a single unit and cost of recharging (every 5 years recommended) because very high skill level required of tech who may not have a lot of experience working on a manifold. Just try to find a tech willing to work on your unusual Chinese brand, hybrid unit, custom install, unwarranteed DIY installation without having to trade your firstborn or get on the down-low with the Mayor to get: insurance, local permits, inspection certs and warranty requirements. With two smaller units with single heads there are configuration advantages through simplicity of installation and externalities relating to DIY install. Also, you could turn off one at night. Or only run both when you're on AC. But don't listen to me I eat meat.

[@MrVlandus]

So you turn it on and off with no issues. I want to run a system for my shed and can get a straight answer from anyone.

This is the 12k btu. It really depends on the temperature you're trying to achieve and the outdoor temp, it can ramp down as low as 200w or as high as 1300w so it's hard to put a number on the power consumption.

If you were going to go with a 12k btu like this I would go 1600w of solar, 2000w inverter would be fine and probably 8 to 10kwh of battery would be a safe bet if you are somewhat shaded.

[@genfari9522]

if you don't have batteries will it run a lot on hot days, all day? I know it wouldn't run at night, but do you think it would run most of the day on a sunny day? I so want to get one of these in Florida, we have a lot of power outages during hurricane season, but can't afford the battery system. I was thinking of badding extra solar panels because I won't have batteries. Do you also know for this exact system you have about how many panels would be good?

[@SmitHVAC.]

Yes, that's the best part about these, You can run them on panel only. I have mine running all day, every day on 6 panels. It usually switches over to household power around 730pm

What is the ideal solar panels for 12k hybrid?

[@SmitHVAC.]

The ideal brand or the wattage? I have most 1200w of Canadian solar panels, will be upgrading to 1600 soon

[@kennethoh6928]

Thank you for replying. I chose 305 watt Hyundai panels mainly for low price but little confused on how to stay within eg4 requirement. Does amperage of panels stay the same if I have 4 or 6 together to meet voltage and wattage requirements?

[@SmitHVAC.]

If you wire them in series you add the voltage, amperage stays the same. If you wire in parallel you add the amperage of the 2 strings.

[@kennethoh6928]

Thank you. So just wire them in series. Do you think more solar is better? I was wondering if having little more than 1100w of panels would help on cloudy days. May be 5 or 6 panels for total of 1500 watt or 1800 watt. I had to buy 10 panels for them to ship so I have extras.

You could go with the 12k if you want to supplement the main Ac. It uses half the solar panels that the 24k needs. 24k would be capable of cooling the while house but requires more real estate for panels

Lets keep in mind this is with the most basic solar levels. I think if I recall there is 800 watts in panels total. These systems can accept up to 3kwh of solar. At those numbers one might expect to see a massive amount more power over a longer period.

@@SmitHVAC. I might have missed that! I'm considering this setup for my Detached garage, but would probably need the 24k, I can only assume I'd need double or more the wattage at a minimum to have it run off grid.... Plan would be to put about 2k Watts of panels dedicated to it. Not sure on doing your "off grid battery" method yet. But possible down the road.

[@SmitHVAC.]

Yes I would shoot for around 2400w of solar. I have another backup method coming next video, stay tuned!

@@aroundtheshop Read the spec sheets about the max solar and max voltage and for a garage that you want to cool and plan on not giving it any grid power then running it slighty colder in there will help that cool or heat last a bit longer.

Dumb question here but still researching..this is the 12,000 btu correct? Is 12k the only AC/DC model? They do not make a 9000 BTU AC/DC? For my motorhome, 9k I think is ideal but it seems their 9K model is AC only.
