- Hi, in this video, I want to show the repair attempt of the last SUN2000GTIL inverter with the AC-short caused by a lightning surge. Are we lucky this time? What does it take to repair this SUN inverters with AC-side failures?
Please like, subscribe and look at my other videos about DIY building of an AC-coupled Powerwall, Repair and local Snakes. Thanks!

Ohhh..you have mounted now the hot air handpiece on the right side, my telepathic message has actually arrived! ; )
Roland, thanks for sharing your troubleshoot attempt.
Thank You Great Video, I have a bunch of them all broke 1-2 years life.
Just out of interest, where are you living? Wondering about climate and grid condition :)
Hahahahaha, timestamp 57:42, "the Sun inverters, they don't like me here too much."
Just to let you know Roland, short after I bought the Aneng AOS02 (same as Zoyi zt-702s) one channel oscilloscope, they released the Zoyi zt-703s with two channels. Same housing but bigger screen and 100'000 counts instead 20'000 in multimeter mode and 20MHz instead 10MHz. Its about 70 USD and totally worth the price, I guess.
Yesterday I got the Hantek DSO2D10. Just wanted to have a bench oscilloscope. My eye sight isn't good enough anymore for the 3 inch screens. hehe.
Its a nice, solid scope with a built in signal generator as well. Lot more features then other scopes in its price range. got it for 7k baht.
@@RolandW_DIYEnergyandMore Congratulations! : ) I thought you'll prefer a bench Oscilloscope and actually kept the Hantek in mind. Beside the bigger screen its better to operate. With the few buttons the Aneng AOS02 one channel version has its convenient to operate, but not so with the two channel ZT703. I still have a traditional Oscilloscope (Hameg 203a) and a little DS102 each with two channels, so theres no need to do further investments so far, as long no special tasks appear. I hope my solar system wont be affected as hard as yours and as it looks this wont happen, cause I keep it insulated from any harm comming out of the grid. Not grid related faults you had only the aged capacitors in your Must inverter so far, right?
@@topeye4202 yes, correct. The off-grid system is working flawlessly for years. My Must inverter is quite oversized by design. I maybe only use 30% of its capabilities just to go easy on the circuits inside. It paid off so far.
@@RolandW_DIYEnergyandMore My PowMr 4,5kW 24V inverter also is burdened just with less than 1/3 in average. The efficiency is surprisingly good in this range, even its just a 24V system. I bought a second one just to have a backup in case and this way I am still below the price of one Must inverter. They are incredibly clean constructed inside, on Lazxxa i have posted pictures in my review (PowMr autorized store). The front is actually real tempered glass, hooked at 6 hidden notches, only two screws must be removed to open it for cleaning with the airgun. OK... i know... I talk too much :×
; )
Kudos to your efforts , but as said before.. see a 3 phase 8 kw video coming in the future Roland 😢
Yeah. I even 5hink there is a 6kW version and it costs somewhere around 1700 Usd. haha
@@RolandW_DIYEnergyandMore yeah, but given what you have spend of the sun's and the investment in cells...
Do think you can get them around 800-900 ex shipping and import fees if you do some good searching ;)
That's a shame but I think you have tried everything you can I to would call it a day
I will leave this board for probing training in future. Just remove the FETs and see what is going on in the background.
Roland, regarding the timestamp 34:00 (settings), the setting parameters to choose for your device is explained on another UA-cam video. I was going to link you a few videos back, but I presumed you were already aware of this. It is important to choose the correct settings for your device, otherwise there will be problems.
Hi Matthew, can you please still link me that video because I do not know all of the parameters from that initial settings. Comments with links will initially go to the review area in my YT-Studio. SO you might think it didn't work. Thanks
@@RolandW_DIYEnergyandMore I will have to try and find the video again. I will get back to you. It was by accident I stumbled across the information (settings) when I was researching information for you. I will let you know if I find the info again or not later today.
@@Matthew_Australia thanks mate. no rush
@@RolandW_DIYEnergyandMore Roland, I found the UA-cam video I was referring to earlier (regarding timestamp 34:00 and choosing correct firmware settings in the "Final Assembly Code" MENU):
ua-cam.com/video/FIhntqGQER4/v-deo.html
You can access the "Final Assembly Code" menu again to choose correct FIRMWARE setting for your device. Watch the entire video for instructions.

Roland, question; s there some kind of device that is something like an inverter, but acts like a buffer between a generator AC output and the main inverter AC nput? I don't like the idea of directly connecting my generator to my inverter hybrid device, since there is a few times where the generator output under load will drop to 190VAC output and the inverter hybrid AC input will still accept this voltage. I don't want to prematurely kill the inverter hybrid AC input capacitors. I will be buying a more powerful generator soon, but I would still like some kind of device inline between the generator and inverter hybrid that acts like a sacrificial component.
Well, you can use the Inverter AC input for Grid only, and for the generator you can use a separate battery charger (similar as I am using it in my DIY Powerwall). They come in many different current options and for each possible battery voltage. The AC voltage input is usually very wide, so it will accept lower input as well. And if something happens one time, you only lose a relatively cheap device (depending on required current), instead damaging the inverter itself (just had a comment recently where somebody said that his faulty generator shorted his inverters AC input)...
@@RolandW_DIYEnergyandMore Sorry for the confusion Roland. I am truly off-grid (as in no grid tie, no mains power from grid). My only source of energy is either from solar/battery or generators.
The inverter hybrid I use has a Bypass feature, whereby I can directly power the house via the inverter (which does not filter the Voltage when in Bypass mode) whilst at the same time charge the battery bank at a maximum of 30AH @25VDC~28.8VDC.
If I instead use a dedicated battery charger, then it would need to be around 100A @24~28.8V, which basically limits the option to the expensive Victron brand.
I was hoping there exists some kind of cheap device that basically acts like a filter, or sacrifical component that may extend the life of the AC input capacitors.
Your latest videos, and reading stories of inverters dying because of bad voltage has made me a bit paranoid. :/
@@Matthew_Australia OK, understand. So during bypass, you are afraid that the drop in voltage will damage the AC charging feature of the inverter. But that drop could as well damage your appliances in the house as the bypass is forwarding generator source 1:1.
I don't think that there is anyting what keeps the generator output stable between Gen and Inverter.
My solution would require the generator to start when the battery is below a certain treshold, then it charges the battery directly and constantly with lets say a 30A charger. The house would draw its demand from the inverter via the battery. Sure, you need to have a big enough battery to act as the buffer.
So, i don't know :(
@@Matthew_Australia but i still think that the inverter AC charger will handle fluctuating input voltage.
@@RolandW_DIYEnergyandMore Looks like the only pratical solutions are to either get a more reliable generator (i.e. larger capacity to handle surging power) and/or to get a larger battery charger. I will do both. Just wanted to make sure before I buy both there was not some kind of cheap gadget that I could use inline to act like a filter (such as something that has capacitors). I already have 4 generators, but none are the sweet spot for my current power demand. One is a Honda 1000W. One is a Honda 500W. One is a Lister (Diesel) 2000W. One is a cheap Chinese brand 6000W. Either my generators are just not enough power, during Summer time or it is too much power and uses too much fuel. I need to get a generator that has continuous rated output of 3600W (since during Summer I would occassionally use approx 2400W), something that uses a Honda GX270 or GX340 engine. The generator is for when there is overcast cloudy days of course. I don't need to run the generator when there is a clear sunny day.
As for the battery charger, my current inverter hybrid charger that has 30AH is too small for my 720AH battery bank and occassional energy demand (during overcast cloudy days in Summer). I will just buy the next generation EPever Upower Hi Hybrid (has 80A charger and also supports LiFePO4 for the inevitable). Cost approx $1150 AUD.
The ususal never ending spending and upgrading that we all get caught up in. :(
