When you have so well build inverter, and the entire chassis is a giant heat sink, and there are no fans, you know there is a lot of thermal headroom and overload capacity for considerable time. Love the fanless design. No dust inside, no fan to fail, just works. As long as it is in the shade, and not in direct sun, it would work super long. Sunny produces very well designed and manufactured inverters. Thanks for the video.
Im glad to see how excited you were to test these .. i have 2 of the same ones running my cabin, garage, and barn on my ranch for the past 2 years now. I live 100% off grid with them running 24/7. The most ove had mine were up to 11kw.. that had me scared for a while. They didnt care one bit though. During the summer they handle my central air in my cabin and by RV at the same time without even thinking about it. They have shut down on me in the heat of the summer when im running the ac and the electric stove and the electric hot water heater kick on.. but in fairness it was over 130°F in the power room of my garage.
The fact that you had to work to reach 7-8 watts by running your stove, AC in both buildings, and all your lights reassures me that a 8000kw inverter would probably be sufficient for a small home that is very energy conscious and running more propane appliances. Thanks for the test.
Never had much luck with SMA inverters for our solar except one. Had 4 SMA failures for our main solar system on our home. Good job. No need for so much excitement. Glad to see they did not blow but that did put a strain on them. Im quite sure the batteries did just fine. LiFePO4 cells are good batteries.
Ours are great. 1st one lasted 13 years and it was replaced with a 2nd one and has been running 8 yrs and counting. 3rd one had a bad relay after a year and got a free replacement.
I'm so far behind the learning curve with lithium ion batteries and inverter technology. I have two inverters, both are the "powerdrive" brand name. They are fairly simple and have an android app for monitoring load %, temp, input and output voltage monitored by the app via Bluetooth. 1000 watt and 2000 watt. I've thought about finding the clock circuit and see if it's possible to do some wiring and soldering to investigate if I could operate them together for a total of 3000 watt or put them in an opposite direction for the oscillator to get a full phase at 230v at 1000 watts, the size of the smaller of the two inverters. I'm disabled so I can't buy much because of my extremely limited income. I can say I really like these videos and I always learn something from each one. I hope you continue to make them so I can continue to watch them and learn. Thank you so much for taking the time to make these videos.
I have the older model 24v 3.3kw Sunny Inland inverter. It has been powering our house entirely for almost 14 years with no issues at all. The only negative is their rating degrades at 40 degrees and in Australia its fairly common to get 40 degree days in summer, especially inside the inverter room. You should have a look at the Australian made Selectronics SpPro inverter range. Next step up from SMA. A little expensive but quality and very functional.
Love your enthusiasm! Got me rooting for you! Thanks for sharing

Great demonstration David. I also tried to overload my single SI 6.0 H. Had a hard time but finally reached the 11 kW with one SI 6.0 H. Seeing it go into temperature derating and reducing output power is quite spectacular ;-)
Excellent test David. I have purchased two of these for my cabin in Colorado and I can't wait to get the hooked up and running. Keep up the great work!
Hi David, why haven't you used SMA sunny boy, to connect them with the SMA sunny island, I think it would be a very good idea, and so you can make a lot of video, thank you very much.
Man wish the guy didn't flake on me on those sunny island inverter I messaged you about. But I just got in the growatt 12k this week i messaged you about. Won't be able to hookup and use until we relocate as florida house hasn't sold yet. Only have to get batteries, racking material for panels and some more wiring for length of run after we get there. So excited that was great video
Been watching you had the same setup bought the BYD and SMA last fall been waiting for you to run it before I run mine:-) good job, I did lose interest in the project. now I can finish it.. Thanks
You mention you use electric heat for the home, thus the solar is not able to get you off grid through the winter. You also have solar thermal making hot water... you might look into using this to heat the house instead of resistive heat... of course, inverter drive heat pumps output heat far more efficiently in much colder temps than conventional heat pumps, so that is another way to supplement the heating off grid. Keep us posted!
Right now my plan is to add another 5kw of solar, and wire it as a dump load to heat the house in winter. I have the panels and parts, just have to get it done before the snow flies.
Gotta love the empowered feeling of being able "trip over" the extension cord with the utility company and being your own utility company as if everything is normal even when pushing it to its limits. I would've gone with the SMA platform, but they don't offer a 120/240 volt split phase single unit version out of the gate and allowing you to add from there. However its design allows that single unit to be configured as a standalone 120 volt, two units for 120/240 volt split phase, or three units for 120/208 volt three phase. If you can get them in a pair at a good price is definitely worth it.
Genetry solar is getting ready to launch it own line of inverters they have wi fi and you can hook them together for 3 phase or for more power and redundancy
Good luck and keep going and going Watch the batts though lolz I ran mine at 23 plus kw and easy 10 min. Fans wide open for a min though but keep going.
THOSE INVERTERS ARE INCREDIBLY AWSOME . MY AIMS DON'T COME CLOSE BUT I'VE GOT IT TO RUN THE WHOLE HOUSE AND FINALLY THE " CENTRAL AC " IF YOU WOULD LIKE TO SEE THE VIDEO AND LEAVE A COMMENT , CHECK IT OUT . BUT THOSE SUNNY ISLANDS ARE THE WAY TO GO . MAY THE SOLAR BE WITH YOU .

Thanks for sharing those experiences with us David, SMA's inverters are great....I wish you could some a day have a test on Mass Sine (Mastervolt) 's brand inverters....I found them so expensive on the market. Please!
Hello, I have a single sunny boy sma 4000tl-us-22-926 in my garage running my 3.9Kw system. Basically Im trying to find out the cheapest way to have the option to cut off from the grid and have one outlet in the garage to run the full size fridge in there or other things in case of an emergency. I dont have $$ for big battery backups. Im not sure if I have to buy one of those islands or if an electrician can wire in some switch and outlet then plug in some little 3K watt converter.. thanks..
Awesome!!!!........Would I be able to use this (2x6KVA) to run a 12-15KW DC motor via a LiFePO4 Battery bank (Size to be determined) on a sailing catamaran with an electric propulsion system? my intention is to have 2 independent systems in each hull.
I don't know how you would do the speed control in that situation. The electric kits I've seen for sailboats are meant to pair with a DC controller for speed control. The short answer is, I don't know. Sorry.
@@DavidPozEnergy Thank you for the super quick response; My design will include 2 separate controllers for two motors directly connected to the Battery Banks (with safety shutoff) and the Inverters will be used to power the house loads (12v, 24v and 220v) from the 48v Battery banks. A solar array will be used to charge the battery banks via the Inverter/charger and MPPTs. One or two DC (or Fuel Cell) generators will be used as a redundancy...... I hope that makes more sense :)
@@4philipp Maybe he doesnt have sails. Did he mean Catamaran when he said "sailing catamaran"? IMO ...He might as well ditch the sails and just go all solar considering the money, effort, and weight so far. -- Maybe have kite sail for down wind extended runs. inhabitat.com/files/beluga2.jpg
BTW, I checked my sunny islands at idle and two of them draw 1.2a together.... that’s 64 watts, or 1.5kwh per day. Heck I had an aims inverter that drew 52wh, 1.25kwh per day and it was only 4kw!! These sunny islands are hella inverters.
Great enthusiasm David! Great Video. I have been waiting for this video. You may remember I purchased 2 of these also. I wanted to wait for you to burn yours in first. Thanks for this video!
Mine are still in the box's. Have been busy on other things lately. But WOW you got me FIRED UP for sure. I will have to get the details from you later on what you have learned along the way. WOW I NEED TO MOUNT THOSE BABIES SOON....
The thing that really stands out to me is that these inverters are not making any funny noises when overloaded like the other inverters do. No buzzing no bongs bings or thunks just effortless power. Having heared the noise even a small victron inverter makes I have to admit I am leaning towards SMA more than ever.
Success is so exuberating when you finally see all your hard efforts and work come together. I wonder how long it would take to deplete your tower of power with this amount of draw? Do you also have your LTO battery bank system running on a different inverter connected to other AC lines in your house or garage or are we going to be seeing another video forthcoming? As always, fantastic job with fantastic results, David !
Hi Craig, I tested the capacity of my battery tower to 24kwh. So I could run 12kw loads for 2 hours. LOL, it doesn't seem very long. But usually can last me 2 days because I'm never running everything at once.
@@DavidPozEnergy Your oven's clean so you're good there for another month. I imagine that if your power grid goes down you'll ration your power to help maximize the amount of time you have it available. Still am wondering about the LTO batteries?
I have two different LTO batteries. The most recent one was a 12v (6s). I drove around with it in my car for a week, and was constantly checking it's temperature and voltage. I ended up taking it out because if I idled there was not enough air movement to keep it cool. I have a second LTO battery that is wired in 48v. I meant to hang it on the wall, but then got caught up in other projects, so unfortunately, it's sitting under my work bench.
here here. If you use good quality components, you get good products. all it takes is 1 poor quality capacitor. Our first sunny boy lasted 13 years in Calif sun.
I wish you had mentioned the batteries that supplied those two inverters. Yes that was a GREAT test on the inverters, but the batteries needed to supply that amount plus...
What are you using for a charge controller with your current setup? I’m trying to design a modest off grid system and can’t decide between the sunny boy and charge controller or an all in one system like the Outback Skybox
I'm currently using a Victron 250/100 charge controller. However, the SMA's don't like when you DC couple, they really want AC couple. So I don't recommend my setup. If you can swing it, the Sol-Ark 12k is hard to beat.
@@DavidPozEnergy Why not just put a Sunny Boy on the AC1 side and let the SI's charge the battery? They don't even need to be in the same building. Just set SB's to "off grid mode."
So awesome 👍 it will be super rare you would typically use that much load all at once either. One of your videos you should go off grid for a week document each day, talk about how much Sun kw input and load used. Also there is a guy in Hawaii that does alot of this stuff he uses heat pump dryer's, heat pump hot water and induction cook top those things would substantially reduce your load if in the future you wanted to be totally off electric bills. Great job was waiting along time for this particular video your enthusiasm for this stuff is contagious
I don't have anything against MPP Solar. But, keep in mind, they are high frequency. So they don't do surges well, and can't over-load. They just shut down. I did a video on one of the models: th-cam.com/video/FUaDmVDcYks/w-d-xo.html
Think I would add a soft start or capacitor to help with the power factor on those motor loads (skill saw, chop saw, well pump ect.) The kvar on those loads are not the best for most inverters. A capacitor should help with the power factor and the power surge. Should be fine once added. Here you asked for a clip awhile ago on the dune race 24v conversion put some under glow and a front light as well. Video is a little Shakey th-cam.com/video/hbX3NBXOCd4/w-d-xo.html
Brilliant!! Great test. Should have probably mentioned at the start that you're network is 3phase. I wonder how they perform the same test when connected as 1p but I assume some of your appliances are 3p supply. Great video. Thanks!
I have 2 phases, each is 120v. They are 180° out from each other. So when you measure from L1 to L2 you get 240v. This is often called 120/240 split phase. It's common in North America.
Great test, it's exciting to see how far you can push things. It seems these take overloading better than AIMS LF do. No surprise there of course though considering they're SMAs. I'd be curious to see thermal images if you have a thermal cam.
If you have the equipment to do it, I would like to see a power analyser real time display at full power on the load side. That would be very interesting.
Will you do a tear down of the inverter at one point? I am curious to see how they managed the cooling considering how silent it is. All i know is that it acutally has two fans but thats just because you said it in the installation video 😂
Yes, the Sunny Island does have a cooling fan. I guess it works well. It designed to deliver 5.43kW at 45-degrees C, continuously. It's unlikely any sealed off room will run at that temperature, so it's very well built.
Great to see you get so excited about it! Pretty neat little units there. I should do the same thing with my 3x LV5048 MPPSolar units. The only reason I went with such a huge amount of power is we have a Nissan Leaf, and I needed 7kw capacity just for the charger on it alone. Also, the fans kick on with almost no load at all, and at max power it'll sound like a wind tunnel. Might be fun to see... I'm currently testing two Electrodacus SMBS0's on a 48v battery bank with 8s nodes per SBMS0. So far it's working very well, but I do wish Dacian would break down and produce a 16s solution since the two halves will need to be top balanced periodically with this split method.
Would be great if you could share what is the draw on each phase and how the SI deal with unbalanced loads. I think that the inverter keeps phases on balance which can lead to losses in off grid applications. Thoughts?
Yep. I've been off grid since April. We don't even have to think about it any more. We can just fire up any appliance, whenever we want, and have never caused these inverters to shut down.
@@DavidPozEnergy Surprise that 4K PV let you run totaly off grid ? . For my house i need 1000Kw month without house heating to go totaly off grid i will need 19kw PV to go true december worst production month you definitively add very low energie consomation.
Excellent advice! They rally should never have been left uncovered while running live (it sets a terrible example for the young ones), let alone while in an overload condition (what if they go pop? ouch into the side of your head), and it's also quite possibly causing the devices' thermal engineering to be less effective - maybe they could have gone even further with the covers on :)
@@pete3897 I would probably not call it an "overload condition". They are made for that. They can do: AC power at 25 °C for 30 min / 1 min / 3 s 5300 W / 8400 W / 11000 W 7000 W / 8400 W / 11000 W Of course you have to be careful. 5750 is max CONTINUOUS LOAD at 25C! At 40C you can only do 5750w load for 3 hours.
My battery bank that's connected has tested to 24kwh usable. So, about 2 hours under that load. But, of course I was just doing a test. I ran it heavy like this for over an hour (close to 2) but then shut off the heaters. It was also sunny while running this test, so we had some solar energy coming in.
Wow that is impressive for sure, hard to get inverters that can actually output their advertised rating these days. Been toying with the idea of adding a transfer switch myself so I can run the house off the shed solar. I only have 400w of solar but if I get a big enough inverter I can at least run a couple big loads for a short time on battery and let solar catch up. In a power outage situation I could at least turn off most breakers and power the important stuff in cycles. I still need to figure out how to keep the snow off the panels though, minute we get wet snow or freezing rain the panels are out of commission for rest of the year since it creates a hard crust on them.
Where do you live? My panels will sometimes get covered up during storms, but usually once the sun hits them (still below freezing air temp) the snow slides off. I'm in MA
@@DavidPozEnergy In in northern Ontario. Basically once there is snow it stays for the year. I can brush off the normal snow but once we get the weird stuff the brush just kind of glides on top. I want to figure out a way to change the incline but that will require more hardware, right now they are flush parallel to roof using unistrut. I have some videos of the install.
Hello David. I just saw your video and have a question. This sunny island can’t control PV cell like the MPP LV5048 right ? I keep looking and I think that I need a Sunny Boy. I live in Puerto Rico and after Hurricane Maria the grip here is a mess and I want a full off grip system. PV with LiFePO4 Batteries. What do you recommend the MPP LV5048 or the Sunny Island with the Sunny Boy. Thanks
That's right. You need something else between the solar panels and batteries. You have two options with these. First, you can use a Sunny Boy as you mentioned. This is called "AC Coupling". Second, you can use a traditional MPPT charge controller. It is called "DC Coupling". Right now I'm using a Victron 250/100 charge controller and it's DC coupled. I have some videos on the Victron if you want to see it. In the future I'm going to add another array and Sunny Boy to demonstrate the AC coupling option.

very nice inverter
Those are built like tanks!!! Running a 4800 square foot house with electric everything, well pump and 4.5 ton heat pump on mine.
The thing that really stands out to me is that these inverters are not making any funny noises when overloaded like the other inverters do. No buzzing no bongs bings or thunks just effortless power. Having heared the noise even a small victron inverter makes I have to admit I am leaning towards SMA more than ever.
Success is so exuberating when you finally see all your hard efforts and work come together. I wonder how long it would take to deplete your tower of power with this amount of draw? Do you also have your LTO battery bank system running on a different inverter connected to other AC lines in your house or garage or are we going to be seeing another video forthcoming? As always, fantastic job with fantastic results, David !
Hi Craig, I tested the capacity of my battery tower to 24kwh. So I could run 12kw loads for 2 hours. LOL, it doesn't seem very long. But usually can last me 2 days because I'm never running everything at once.
@@DavidPozEnergy Your oven's clean so you're good there for another month. I imagine that if your power grid goes down you'll ration your power to help maximize the amount of time you have it available. Still am wondering about the LTO batteries?
I have two different LTO batteries. The most recent one was a 12v (6s). I drove around with it in my car for a week, and was constantly checking it's temperature and voltage. I ended up taking it out because if I idled there was not enough air movement to keep it cool.
I have a second LTO battery that is wired in 48v. I meant to hang it on the wall, but then got caught up in other projects, so unfortunately, it's sitting under my work bench.
thats German engineering for you! I also have an SMA inverter because I trust it more than any other brand out there...
here here. If you use good quality components, you get good products. all it takes is 1 poor quality capacitor. Our first sunny boy lasted 13 years in Calif sun.
Thanks for sharing, but I would have really liked to know what was the amp draw on the batteries during that max load.
I wish you had mentioned the batteries that supplied those two inverters.
Yes that was a GREAT test on the inverters, but the batteries needed to supply that amount plus...
I have several videos detailing my batteries.
1:10 oven, hot water heater, and dryer on at the same time. 15kv easy
What are you using for a charge controller with your current setup? I’m trying to design a modest off grid system and can’t decide between the sunny boy and charge controller or an all in one system like the Outback Skybox
I'm currently using a Victron 250/100 charge controller. However, the SMA's don't like when you DC couple, they really want AC couple. So I don't recommend my setup.
If you can swing it, the Sol-Ark 12k is hard to beat.
@@DavidPozEnergy Why not just put a Sunny Boy on the AC1 side and let the SI's charge the battery? They don't even need to be in the same building. Just set SB's to "off grid mode."
THIS is why I'm subscribed to you 😁 great video thank you
So awesome 👍 it will be super rare you would typically use that much load all at once either. One of your videos you should go off grid for a week document each day, talk about how much Sun kw input and load used. Also there is a guy in Hawaii that does alot of this stuff he uses heat pump dryer's, heat pump hot water and induction cook top those things would substantially reduce your load if in the future you wanted to be totally off electric bills. Great job was waiting along time for this particular video your enthusiasm for this stuff is contagious
I've been running off grid since April. I didn't realize I was supposed to video it each day. LOL
@@DavidPozEnergy cool off grid since April, so awesome I'm going to have to start something soon think I might go MPP solar inverter
I don't have anything against MPP Solar. But, keep in mind, they are high frequency. So they don't do surges well, and can't over-load. They just shut down. I did a video on one of the models: th-cam.com/video/FUaDmVDcYks/w-d-xo.html
Think I would add a soft start or capacitor to help with the power factor on those motor loads (skill saw, chop saw, well pump ect.) The kvar on those loads are not the best for most inverters. A capacitor should help with the power factor and the power surge. Should be fine once added. Here you asked for a clip awhile ago on the dune race 24v conversion put some under glow and a front light as well. Video is a little Shakey th-cam.com/video/hbX3NBXOCd4/w-d-xo.html
Brilliant!! Great test. Should have probably mentioned at the start that you're network is 3phase. I wonder how they perform the same test when connected as 1p but I assume some of your appliances are 3p supply. Great video. Thanks!
I have 2 phases, each is 120v. They are 180° out from each other. So when you measure from L1 to L2 you get 240v. This is often called 120/240 split phase. It's common in North America.
Great test, it's exciting to see how far you can push things. It seems these take overloading better than AIMS LF do. No surprise there of course though considering they're SMAs. I'd be curious to see thermal images if you have a thermal cam.
I don't own a thermal camera. Can't afford it this year, maybe next.
Well done! Love it!
If you have the equipment to do it, I would like to see a power analyser real time display at full power on the load side. That would be very interesting.
The best I have is an oscilloscope. Sorry.
You are really awesome man 👍🏻👍🏻
Will you do a tear down of the inverter at one point? I am curious to see how they managed the cooling considering how silent it is. All i know is that it acutally has two fans but thats just because you said it in the installation video 😂
Yes, the Sunny Island does have a cooling fan. I guess it works well. It designed to deliver 5.43kW at 45-degrees C, continuously. It's unlikely any sealed off room will run at that temperature, so it's very well built.
Great Job. Way to go.
Put em to the test David you are awesome. The adult version of kid in a candy store lol.
nice! I overheated my 2 magnasines at 11000w continues but never overloaded them, but I have a fix for it :D
Thanks. I enjoy your videos too.
How was setting up the Li Battery settings on the SMA Inverters?
It's not easy. I ended up using a raspberry pi with a software from Github. github.com/madsci1016/SMAVenusDriver
Great to see you get so excited about it! Pretty neat little units there. I should do the same thing with my 3x LV5048 MPPSolar units. The only reason I went with such a huge amount of power is we have a Nissan Leaf, and I needed 7kw capacity just for the charger on it alone. Also, the fans kick on with almost no load at all, and at max power it'll sound like a wind tunnel. Might be fun to see... I'm currently testing two Electrodacus SMBS0's on a 48v battery bank with 8s nodes per SBMS0. So far it's working very well, but I do wish Dacian would break down and produce a 16s solution since the two halves will need to be top balanced periodically with this split method.
Can you please send me a link if you make a video about the two working on one 48v battery? I'd love to see it.
@@DavidPozEnergy You bet. I have the footage taken already and have to edit it - poorly. Will let you know when it's uploaded and available.
Would be great if you could share what is the draw on each phase and how the SI deal with unbalanced loads. I think that the inverter keeps phases on balance which can lead to losses in off grid applications. Thoughts?
These two inverters can not share load from one phase to the other. It is possible to overload one phase while the other still has room.
Now you can say goodbye to grid power. This can handle anything you want to throw at it!
Yep. I've been off grid since April. We don't even have to think about it any more. We can just fire up any appliance, whenever we want, and have never caused these inverters to shut down.
@@DavidPozEnergy Surprise that 4K PV let you run totaly off grid ? .
For my house i need 1000Kw month without house heating to go totaly off grid i will need 19kw PV to go true december worst production month
you definitively add very low energie consomation.
I know you were excited, but careful with that finger. Pointing behind you at uncovered inverters could have ended badly.
Excellent advice! They rally should never have been left uncovered while running live (it sets a terrible example for the young ones), let alone while in an overload condition (what if they go pop? ouch into the side of your head), and it's also quite possibly causing the devices' thermal engineering to be less effective - maybe they could have gone even further with the covers on :)
he is crazy rich guy
@@pete3897 I would probably not call it an "overload condition". They are made for that.
They can do: AC power at 25 °C for 30 min / 1 min / 3 s 5300 W / 8400 W / 11000 W 7000 W / 8400 W / 11000 W
Of course you have to be careful. 5750 is max CONTINUOUS LOAD at 25C! At 40C you can only do 5750w load for 3 hours.
Impressive! How long would your batteries hold up under that load?
My battery bank that's connected has tested to 24kwh usable. So, about 2 hours under that load. But, of course I was just doing a test. I ran it heavy like this for over an hour (close to 2) but then shut off the heaters. It was also sunny while running this test, so we had some solar energy coming in.
Does the inverter handle compensstion?
Wow that is impressive for sure, hard to get inverters that can actually output their advertised rating these days. Been toying with the idea of adding a transfer switch myself so I can run the house off the shed solar. I only have 400w of solar but if I get a big enough inverter I can at least run a couple big loads for a short time on battery and let solar catch up. In a power outage situation I could at least turn off most breakers and power the important stuff in cycles. I still need to figure out how to keep the snow off the panels though, minute we get wet snow or freezing rain the panels are out of commission for rest of the year since it creates a hard crust on them.
Where do you live? My panels will sometimes get covered up during storms, but usually once the sun hits them (still below freezing air temp) the snow slides off. I'm in MA
@@DavidPozEnergy In in northern Ontario. Basically once there is snow it stays for the year. I can brush off the normal snow but once we get the weird stuff the brush just kind of glides on top. I want to figure out a way to change the incline but that will require more hardware, right now they are flush parallel to roof using unistrut. I have some videos of the install.
What's the noise ratings
Very Impressive!
Hello David. I just saw your video and have a question. This sunny island can’t control PV cell like the MPP LV5048 right ? I keep looking and I think that I need a Sunny Boy. I live in Puerto Rico and after Hurricane Maria the grip here is a mess and I want a full off grip system. PV with LiFePO4 Batteries. What do you recommend the MPP LV5048 or the Sunny Island with the Sunny Boy. Thanks
That's right. You need something else between the solar panels and batteries. You have two options with these. First, you can use a Sunny Boy as you mentioned. This is called "AC Coupling". Second, you can use a traditional MPPT charge controller. It is called "DC Coupling". Right now I'm using a Victron 250/100 charge controller and it's DC coupled. I have some videos on the Victron if you want to see it. In the future I'm going to add another array and Sunny Boy to demonstrate the AC coupling option.
@@DavidPozEnergy Thanks David
Good Working
