Subscribed, I have been thinking about going high voltage for a while, now I am convinced. Most of the low frequency inverters on the market seem to be lacking but I like this one, will investigate. Thanks!
Thanks for re-making your series on high voltage solar. It's a lot of work to produce videos, and it must be a bit frustrating to put in the work and not get many views. I've had ~10 million views of my content over on the Quora website, and I just posted a link over there to this video. It will be interesting to see if any of my Quora followers are intrigued enough to come check this out.
Hi Jimmy you know I am just an average guy who built a solar system for the first time by common sense.I am by no means an expert.what I would like to see is these solar expert installers making these durable high voltage systems.And thankfully we have some on the channel getting ready y do just that.I can't wait to see their videos.Thanks so much for the share sir!!🙂👍
I actually for a long time thought I was crazy for paying for extra parts when buying stuff. But that really heavy stuff needs to just be fixed, not rma'd. Saved my bacon a few times. Fixing things is far quicker than mail solutions, especially with out of country stuff. Pro tip for capacitors is to use a really big resistor or a load rated for the caps to drain them.
Thanks Mike! I will start planning my house soon and I was thinking about going mainly DC only and avoid using the inverter as much as possible (mainly for efficiency/performance). I was not able to see anything similar so far, dc lighting/computers/laptops/tablets/phones even large appliances where possible (ev charger/fridge/induction cooktop/washing machine/over etc..). I'm looking into POE/USB and the new Class 4 - FMPS for HVDC safety. I think HVDC is the only solution for off grids with normal/high power demands. Finally, for failover I would design two systems in one (eg. two solar chargers, two strings, two inverters etc..). Best regards from Greece ;)
What I like about these Sandi inverters is the simplicity of their design. Ask any experienced engineer, and they'll all tell you the same thing, it's called "KISS" (keep it simple stupid) The simpler the design, the longer it will last, the better it will perform and the easier it will be to repair. That's why I would never buy a high frequency, transformerless inverter with their complex circuitry and their ultra high parts count. There's just too many parts that can fail. They have a much shorter life expectancy, they offer poorer real world performance, they're less safe to operate and they're very difficult to troubleshoot and repair. On the rare occasion that you might have to repair this Sandi, high voltage inverter, you simply turn the inverter off, disconnect the battery source, wait until the capacitors are fully discharged, remove a few screws, swap out the fail board or component, replace the screws and your done. You could never do that with one of those high frequency, transformerless inverters. For one, their are no replacement boards or schematics available, and two, when a high frequency inverter fails, they typically take out multiple circuits in the inverter. Keep up the good work Mike, you're doing a great service to the off grid solar community!
Excellent video,Mike! Thanks for sharing. It’s nice to see what’s coming my way and get the chance to see it inside first. The settings are straight forward. I am going to request the PI for the battery system from Carrie, and mention the 30 kW for you with all the goodies I got. What do you think of 200-500V range? You could always step up your system voltage in the future if you’d like. The 200-500V is not their standard configuration, but they were able to design one like that for me. At the time when I ordered the inverter, I had the plan to power it with either 96S, 104S, 112S or 120S . I settled for 120S . Wide voltage range helps to adopt with wider high voltage span, especially with what’s coming next- the sodium ions 😊. This inverter is built to last, and the repair; if any, is a fun project. There is no need to think of a parallel setup ever.
Hi Adam 200-500 volts sounds great.And I glad you got to see what your getting.Mine is 216-450 volts but as you can see iam running lower than that with no problem.Thats why I say bring on the Sodium Ion cells.😁💯
Now thats pretty detailed. Solar community is very lucky to have you. May i ask whats the standby power consumption of the inverter without any loads sir? On a typical 48v system with toroidal core low frequency 10kw, it gives me 50 watts of draw without any loads. I have two toroidal low frequency running in parallel so the standby draw is around 100 watts. Love you mike, and what you do.
Mike I tired that link you provided for the inverter and is a dead link unless I'm missing something here, please post it again, I think I'm going to order a inverter if I can make contact,
Understand.If people have the money they can buy a second inverter and use the AC bypass to connect them so if one goes out the other in ups mode will take over.🙂
It is a common, and wrong, assumption that the voltage from solar panels will depend strongly on how brightly lit they are. Nope. Solar panels put out almost the same voltage when dimly as when the sun is strong. What changes is the available current at that nearly constant voltage. The current is directly proportional to the light level.
Yes agree but to get the charge controller up in charging earlier in the early morning it has to hit a certain voltage to start so higher voltage on my controller will help me get there I am thinking.i could be wrong.Like I said trial and error since this is my first time building one 🙂
The OG with the OG system.
Always enjoy new videos!

I want to build your HV system for my home. I live in town and have to figure out for my home. God bless you and your family. Keep up the good work.
Earned a sub. Mental system!

Thanks for the video,on inverter, and apart to show how easy it is to work on,,that's simple, thanks Mike
That's an amazing system thank you for showing it. Very helpful 😊
that inververter looks like it its eady enough to service heavy dutty transformer

Yes going to do that soon.So everyone will know again
Love this video Mike, please share the links you mentioned I don't see them here unless I'm missing something.
I just gave the contact info on inverter video description.As I do the other parts of the series I'll give the contact info in the description . 👍
@@mikeg2321 Got it thank you sir, what voltage do you have your batteries at? I have 40K of batteries here to play around with.
@@russt9395 204 volts but I am taking them up to 256 volts nominal soon
That is one massive,and awsome inverter,i wonder what is the capacity on it
This is a 25 klw inverter.
And what is the voltage of your battery bank? Thanks for these awesome videos!!!
@@83kaszas 25000 Watts
@@dubglener6416 204 volt but next time you see it it will be 243 volts nominal
@mikeg2321 absolutely impressive!! So these are 68 cells in series for now?
Is the inverter doing the charging as well? Or do you have a separate charge controller. ?
This one doesn't have the charge controller it's on the other wall Ipandee.thats why I want the 30 klw with everything to show everyone
Mike I tired that link you provided for the inverter and is a dead link unless I'm missing something here, please post it again, I think I'm going to order a inverter if I can make contact,
carrie@sandi.cc or look up SANDI Electric on Alibaba and ask for Carrie
Thank you Mike I really appreciate it.
bro ur whole idea of no backup inverter will change over time , time will tell, like I said I learned my lessons, superb system u got tho

Nope. Solar panels put out almost the same voltage when dimly as when the sun is strong. What changes is the available current at that nearly constant voltage. The current is directly proportional to the light level.
Actually a full blown bright clouds will give you tiny bit more voltage than an open hot sun. But at the expense of the amps. Your correct.

@@mikeg2321 its your first time, but you have the best build out of all solar youtubers out there. Simple, yet superior. Far ahead of the pack
