I've installed 3 of the DIY Mr. Cool 1 1/2 ton units in both my home and RV Park office. It does get easier to install after the first one. I purchased all 3 Mr Cool units at Lowes for $1500 each. It's a better option to go with Mr Cool considering the price advantage using DIY method. The cost advantage give you a simple choice when the unit breaks down. It's money ahead to replace than to get a HVAC company to work on it. On the issue of line sets, I suggest you match the line set distance between the indoor and exterior so you don't have the ugly line set coiled up, or install a garden hose hanger for the excess line set and use a RV Tire cover to hide and protect the line set. I've also use a vinyl fire hose as a line set cover for protection and it makes a very nice finished look.

Others have posted online but everyone leaves out the important details. For instance, on a 12 volt system ...how many watts of solar panels need to be installed to make it function? It is very frustrating that the videos, even Will's video on running the little 5000 BTU 500 watt window a/c does not indicate how may watts of solar panels to dedicate to the unit. We are beginners and need to know this. EG4 does not answer their phone or emails and their downloads don't say either...so frustrating!

[@Tommy-B.]

I have 4 of the smaller pioneer units. The lines were not precharged, but the outdoor unit was. They do say to run vacuum on the system to test for leaks as well as getting air out before opening the valves on the unit. I love them. They work great. My only issue is they do not connect to WiFi. I’m a trucker. I would like to turn the temp down when I’m almost home. Although they don’t take long to cool down, they are better at maintaining a temperature. Since they don’t use much electricity, I just turn them up a few degrees when I’m gone and let them run. Also they sell decorative covers for the lines. At least coming down the wall. Then you can secure the remaining coil behind the unit.

Will, when you said thousands of dollars to recharge system, it reminded me of the many vehicles that I recharged using Dust off (R152a) refrigerant only about 3 dollars a can and works excellent. What would be an interesting experiment is measuring the efficiency of R152a vs R410a. R152a has a low molecular weight, causing lower high pressures. I would guess a measurable increase in efficiency

So a good product for custom line-sets is something Pioneer makes. It's called Kwik-E-Vac. It's a can of ethanol and R-152a (Difluoroethane), which is an environmentally friendly HFC which mixes well with R-410a. You connect the line set and leave one side open. You then connect the can to the line set port and flush the lines. Then you seal the system while the refrigerant is still expanding and then pressurize it with the can to test for leaks. The small amount of R-152a then just (very slightly) dissolves in the R-410a. Pioneer basically shows that the small amount of R-152a in there makes no measurable difference in performance or function.

I just installed a Mr cool 12k diy unit into my 42ft RV. It was relatively easy to install with the complexity coming from the RV install since rvs are built with such thin walls and floors. Put the outdoor unit in the generator port under the 5th wheel. Open the baggage door for ac, close it to protect it during travel. It pulls cool air from under the RV and pushes what little hot air it outputs towards the front. Thankfully no short cycling which was a concern prior to install My RV had a 15k and 12k roof mount units factory but in weather over 90° they struggled to maintain 70° for the 500ish sqft space. This small minislip is powered by a 30amp extension cord plugged direct into the meter box when an extra port is available at the campground or it can fairly easily run off the factory 50amp wiring. Just can't use the microwave at the same time. Solar is still beyond my grasp because I don't believe I have enough usable roof space to keep up with my use. On top of batteries/inverters, charge controllers get heavy fast in an RV.

[@railstop]

[@Chimel31]

The 12K BTU hybrid mini split has a VOC (Open Circuit Voltage) of *380V* max for the photovoltaic DC array. That's 8 x (24V - 72 cells - *44.6VOC)* solar panels, but only 7 in mild winter, when panels are more efficient and voltage 10% higher. Maybe only 6 in colder winters, this needs to be computed locally so it does not void the warranty. These panels need to be mounted in series, to add up voltage, different types of solar panels have different VOC and amps. A solar panel or a series of them is typically around 10A, within range of the 12A max ISC (Short Circuit Current) of the mini split, so adding a second series in parallel to double the amps would output way too much amps and add fire when you want ice... I thought it would be more efficient to power the heat pump directly with photovoltaic DC, because there would be less power conversion losses, but this hybrid mini split is actually only 21 SEER2, compared with the regular 115V AC one at 28.5 SEER2. So I wonder if it's not better to get the regular 115V AC mini split and a regular PV inverter. It's $150 more expensive, but it would pay off handsomely in the long run. But unless I am reading the specs sheet wrong, 52db is hugely noisy for an A/C: It's only 25dB max legally in France, for instance, so most A/C exterior units on the market there are rated at around 23dB. Imagine in a small village if all houses emitted 50dB, let alone 52, because decibels are an exponential, not a linear progression. Imperial vs. metric decibels? 😃

I'm not understanding the advantage of the hybrid heat pumps for the average solar power enthusiast. I'm guessing the solar panels would be dedicated to the heat pump and not also connected to a charge controller and batteries. If the heat pump is on, say, 50% of the time then the solar power produced during the other 50% is wasted. Am I understanding this correctly? If someone were only wanting to power the heat pump, I can see the benefit because it'll avoid all the other components of a typical solar system.

[@MartyinPS]

Airspool is a Company in Vegas also precharged lines

[@stevenscott4096]

I'm not familiar with the EG4 units, but have installed a lot of Fujitsu units. We always used the metal mounting plate as the template. I'm assuming the EG4 use a mounting plate for the wall mount units.

@use_withwillprowse ??

[@fduran6993]

You should cover the external units from the sunlight. This way the efficiency should improve. My knowledge is that so many units make your set less efficient that one large unit with several fancoils connected. A final idea, why you don't provide a dc line from the batteries rack directly to this new external unit? During daylight pv provides electricity and during sunset batteries kick in.

[@BobBob-il2ku]

I have the same question regarding DC

[@Nicedesk]

I have the same question as the previous same question. Why not have a battery provide DC for non solar times?

[@loucinci3922]

Hello from south Florida. Nice overview. Six heat pumps? WOW! I often wonder if I could go solar and have enough PV to run AC. Huge loads .Thanks for sharing

[@matthewknight5641]

I bought the 38 seer inovair and dude so far its amazing. Goes qs high as 13500 and as low as 2000. Its 220 but runs great on my sungold split phase inverter. It pulls between 200 to 300 watts after the first 10 or 12 minutes it takes to cool down the camper. It was actually the last piece of the puzzle to get me comfortably off grid.

[@matthewknight5641]

@@southerncatlady6680 I saw one that was a 42 seer but it was about 5 grand. The 38 seer was 1700 bit had to buy the lineset seperate so it was about 2000 with everything. I have about 30 grand in all the solar equipment and stuff I've bought to be off grid. Thats both solar power systems and water pumps and the minisplit and just all I spent to be off grid capable. Funny thing is it's a old camper too lol. It's a 93 model 30 foot holiday rambler. It's been kept indoors all its life and was never rained on until I bought it from an older couple. It's actually really nice but it's old if that makes any sense. When I found out I had stage 4 cancer me and the wife wanted to know that no matter what that we would be able to have power and live comfortably while we travel. We live in this semi truck most the time doing long haul trucking but when we are not in this truck we are in the camper. It's a Strange way to live I guess but it's fun and we love it. And yes 38 seer is super efficient about 200 to 300 watts to keep the camper cool

[@matthewknight5641]

@@southerncatlady6680 been in remission for over a year now. Did the radiation and 2 rounds of chemo. Then took a dog wormer medicine called fembendozal and it saved my life. With not being sure if the cancer would return was what got me into trying to build a life where I could still survive if I got sick again. I invest a good part of each check into my off grid camper just trying to prepare I guess. I've spent alot of money on it and if I had the discipline to had of just saved the money I might would have came out cheaper just paying electric bills but it's turned into a productive addictive hobby lol. Thanks for the well wishes and the conversation. Glad ypu beat the cancer too

[@dimitriid]

How much solar power you need for that 12k btu at 28 seer? I'm guessing about 600-800w (But obviously far higher peak) would do the trick since it takes about 1200-1400 for a similar unit I have that's only 19 seer but if you can confirm that'd be great.

[@mainelife4268]

Pioneer comes with units charged. The lines get flushed with a can of something. It connects easily.

[@frankcherry3810]

I like to charge the Freon myself. I can make the lines custom. I get hard plastic line covers to protect and hide the lines

[@marzsit9833]

some states have restrictions on who can buy a tank of refrigerant. in my state it is not enough to be epa certified, you also have to have a business license. the only refrigerant you can get without certification or a license is r134a and only in the small cans.

[@frankcherry3810]

Your right, but I live in Thailand now

[@kasken719]

I had a leak at the same exact point on that model. Outside of that, it's been working 24/7 to keep a storage building temp regulated with no issues.

[@WillProwse]

Ahh no way! Darn it. Did you re charge it?

[@dodongamericano9049]

You are a solar genius Will! I have a Mr Cool mini split system and would like to convert it from grid power to solar. Can you please make a video on that?

[@douglasrobbie9998]

Live in NE in 2000sq ft house and a 5000btu window AC can cool upstairs and another one can cool downstairs. So my cooling needs is not the same as in SW. What I don't understand is why these size mini splits don't come with option for 2 inside air units instead of just 1.

[@boomermatic6035]

Documentation and details are my main complaints about EG4 products; a mounting template is simple to create and would only take an hour or two for the CAD person to create and would improve the customer experience greatly.

[@31337cyberhuman]

I’m in Oklahoma and the MrCool has worked well in the cold winters until we get to anything below about 30 degrees Fahrenheit. But ive had it work down to 0* or so, but not very well and becomes inefficient at that point.

[@waynewilliamson4212]

so agree with the multiple units statement. I had mentioned that a while ago to my air conditioning "guy" and he looked at me like I was crazy.

[@evil17]

Great vid & review Will. To be fair on ‘Old Mate’, any joins in gas fittings: welded, flared, cliplocked or other can be problematic, even for good professional fitters for reasons they may not always be able to control; age, vibrations, accidental knocks, poor flare fittings quality & of course incorrect torque. I would like to see the manufacturers of these units add a DC interface/posts so we could also connect a 12v, 24v or 48v battery for extra runtimes, to help overcome shading issues and make use of any excess solar that may be available on a given array, as often these units are using much less power than their pv array is able to provide. Imagine if u have a 4wd, camper, caravan, etc, with aux battery power available, parked under an awning or near one of these units around ur house/shed/guest house, you could potentially plug in to the AC unit to make better use of those batteries and keep them maintenance charged at the same time, while enjoying extended periods of aircon after sundown. Cheers

[@George_us]

You forgot to mention that Pioneer unit has no in-rush current. I have been running a 9K BTU, 110 volt using Bluetti AC200MAX for several months.

[@carsonc1272]

Wow, EG4 is really working hard to get things right. I'm incredibly impressed with this company.

[@scruples671]

Refrigerant for minisplits doesn't cost $1000 dollars but labor might.

[@bikerboyz70]

Gm will at your 1:58 mark you stated that this eg4 runs on 120 or 240v but spects sheet says 115 v only i believe. Wanna use this unit overseas where only 220v is available besides solar grid

[@goodcitizen4587]

I need to install one of these here in Florida. Thanks!

[@wd8557]

Usually chraged line set or not, the unit it's self comes ready for 15 to 20 ft line set charge.

[@GavinStoneDIY]

Really neat that they’ve come up with a precharged line. And I believe you’re right. I haven’t seen anyone else with those precharged lines.

[@jmpattillo]

From what I’ve read, you want those extra line coils to be horizontal to prevent oil traps.

[@WillProwse]

That's why one of the units has it coiled horizontally but I found that to not matter at all

[@rpsmith]

@@WillProwse -- coiling it vertical will starve the compressor of oil and will shorten its life!

[@WillProwse]

@@rpsmith I've read a lot of people say that and a lot of people who disagree. I don't know what to believe at this point 😂

[@JamesCusano]

@@WillProwseTo add my anecdotal evidence to your uncertainty: About ten years ago I did my very first two ductless split installs with extra line set coiled vertically behind the outdoor unit after our initial trainer (the distributor) misinformed us that a minimum of 10’ of line set was required between the units and told us the vertical coiling was the proper solution for closer runs. Neither have ever had any compressor problems to this day. We stopped doing coils for close runs after that only because a subsequent training informed us the extra line set length was actually unnecessary. I suspect the oil trap affect may have applied more to the lower pressures the old R22 systems used and the higher pressures of the R410 systems may force the oil to keep moving along.

[@SeleneHammer-pn8hr]

Pioneer does the inverter plus and has the template and precharged lines. You can easily extend drainhose cost like 5 bucks. Does the eg4 solar one need a hook up or can it solely run on dc?

[@MyCabinLife]

That's what I'm trying to figure out can I just plug solar panels in it and do nothing else? I don't want to have to hook it to battery or an inverter or plug it into an electrical panel. I realize as soon as the sun goes down then it will not work.

[@john99776]

Hi Will. Off topic but just wanted to let you know that I contacted Renogy customer service a few days ago about a 10W solar trickle charger that died and ruined an expensive AGM pure lead battery in my cabin. Their overseas based service wasted 2 or 3 hours, multiple phone calls, receipts and photos, of my time, gave me no help on even its 25 year output warranty - all that I was asking for, and insinuated that I don't know how to prove to them that I know how to use a simple volt/ohm meter (I'm a registered professional engineer). I also have 2 of their 100W solar panels. I hope I never need assistance with those. In my opinion, a good company to steer clear of. Enjoy your videos very much. Thank you.

[@dansplett8303]

Thank you for your information on the eg4

[@RobertL78]

Some shade over those outdoor units will help them tremendously in the middle of the day.

[@teachingandlearning]

I've had the 1 ton York unit installed for $1100, including the install, the base to mount it on the wall and the unit ($600). I've had some less expensive 1 ton units purchased for $400, a Ciac, which is the Carrier brand. They are not connected to solar but 2 1-ton York split systems cost about $100 per month in electricity, which is the entire monthly bill. Also, it may be as hot ot hotter in my area compared to Las Vegas. The high power electric lines cost around $1000 to install separately from an electrician.

[@SpencerLAPower]

The link on here is not for the hybrid 12k. The hybrid 12 k Mini split is 22ser not 28ser

I just bought the EG4 from signature Solar. I just got it and installed it. The unit is DOA. Won’t power on. 😢😢😢

[@freebirdgliding]

Hey Will! Deye makes the EG4 units they just rebrand them. I have installed 2 of the 24k btu units. They are producing about a gallon of water per day.

Can the lines be buried under ground to aid in winter heating?

[@J.W.McFarlane]

I have had a similar unit running 2 years. I think it is time to catch up with will and add another unit.
