yah he is

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.

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!

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 ;-)

I love your enthusiasm, keep up the good work.

Lovely to see you happy and jumping stay blessed. Nice video.

Thanks for the videos. I have the same setup but it isn't installed yet so these videos are really valuable to me.

those are nice inverters as well, thanks for the entertainment.

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.

That was awesome thank you for the video

Very Impressive!

Great video, it is wonderful seeing someone living my dream.

AWESOME!!!

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.

Fun video! Great inverter

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.

THIS is why I'm subscribed to you 😁 great video thank you

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.

Watching you jump around with glee really made my day!🤣

You are really awesome man 👍🏻👍🏻

Great Job. Way to go.

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.

very nice inverter

Thanks for sharing, but I would have really liked to know what was the amp draw on the batteries during that max load.

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!

Those inveters are monsters 14kva that is serious powers ....good works man

heya nice max test just great

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.

@DJMT-Africa

Rated output current for the Sunny Island 6.0 and 8.0 is 20A, with a peak of 120A for a short while. The limit would, then, be the battery.

what was the amp draw on the batteries?

Does the inverter handle compensstion?

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.

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..

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.

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.

So what do you think your average daily consumption will be?

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?

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.

@@DavidPozEnergy Absolutely! That is what we have. Several Sunny Boys 300' from house under 12kw solar array. 2 SI in the garage. The SB are on the LOAD (AC1) side if the SI'S. 'David's test was a great example of how the SI would work at night with no solar input. During the day, the Master SI is the local grid "gate keeper" and adjusts all the inputs and outputs of the SB's by adjusting the frequency. The SB's see it and respond immediately. You can, as in our case, run 12kw of loads and when the battery is full, no power is actually going through the SI at all. All you have to do is to set the SB to "off-grid mode" and they will react to frequency shifts by increasing or decreasing their power output. All done in the existing AC wiring, no other communication needed!
