Thanks Mr. Swedish Man. I'm connecting mine up backwards as I want My solar input system as primary. Thank you Good Job. Gus
Great information since I just bought one to install.
Lovely analysis sir
Thanks so much for this video
Great video!
Great video buddy, thankyou
48 Amps system has been working with one of this 100 amp rated 3 poles 220 for over 8 months now, cycling between sources everyday without flaws, no sing of overheating or hot spots or anything of that matter. Computers only reset sometimes going from A to B, but stay on form B to A.
A UPS (Uninterruptible Power Supplie) will solve your computer problem
@@josephrosa5845 Or simply a faster Transfer Switch
How is it holding up? Any update. I'm about to put my load of about 40 Amps with this kind of switch.
@@tarakivu8861 Don't you think a UPS would be much less expensive than buying and replacing the transfer switch?
Thanks
I would love to see how to do the primary
Not sure you can use it for inductive load, where in-rush current may exists. The current can be hundreds time larger than normal.
Dear can you explain the difference b/w ats switch used for normal and solar invertor. As if you see you found for solar they offer diffetent but technical specification is same. And also My concern is that is this switch can harm for load like fridge etc. Thanks
Could you please tell me how i can use the no nc c option in this to auto off the generator when the grid (main power) comes.
curious, how do you connect 3awg wires to this terminals for 100amp usage...? thank you!!
help please do this item only use a 220 only input into the power controller? because I live in us when I use 120 the switch does not work when I turn off primary please let me know. if you can help me.
Can these be hookup with out the on/off switch.want to hookup direct for inverter & generator
Updated review since the video is 3 years old. How much load are you using on this device. Thanks
do you have those wires connected to 2 seperate wall sockets where one is on and the other is off?? or how does it work?
I wanted to install this kind of automatic switch to my entire house, but after seeing this explanation i prefer a manual, thanks a lot for your advice about this cheap device. Can you please recommend a manual certified switch for 220v ( 1 neutral and 2 fase of 110v each = 3 wires in total from the pole outside) Thanks.
you need to get a nema 3 manual transfer switch rated at the amperage you are switching from/to most are expensive and large electrical supply house sels them.
it all depends what you want to keep alive when power loss.
Can I use this to switch between phases?
Please can you link the manual transfer switch? (The one you say you use)
Do you think you could add one of those big AC capacitors to deal with the switching time 30ms? I dont know how they are called its used for air conditioners or motors I think.
Wont help here om afraid
Is there any model that is certified and that can be recommended? From Hager or Schneider or ABB?
Thanks for this video. Can you please say if the control voltage is 120 or 240 (AR and AN)?
Its 240.
Any model from schneider or any good brand?
Did not understand will it only work 50 times ?
i have sma sunny island 8.0 with nissan leaf batteries and when grid goes down these looks to be the solution, anyone know how to make the install ?
I got the 8ms version... It's true no micro-cut for computers, etc.... but ... versus time, the mechanical part will fai (misalignement of the two rotating metal contactors).... In average, it works one year for two transfert / day in average.... :(...
This was helpful. Thanks
Work whit 110v?
Ive been saving to buy the digital version(MOES) with much shorter delay time than this mechanical one.Will Prowse has vids. demonstrating running computers and (I believe) even a window AC. Rated for 100k switches!...but this mechanical one ....IDK.
I run it with computers. It's 10ms switch time that is good enough. We need mechanical here to get it approved.
they say is used for generator backup, but also you need extra controller for diesel generator , to know the state of the generator and to control the warm up delay switching time and also the cool down timer for generator after grid on. what you can say? cand you do un diy project for diesel generator?
Don't have any
Great video. Do you check switching time on the same phase? I think it will be great to check switching time on different phases to see time switching in configuration with UPS or off-grid PV inverter.
@Piotr Rękawek : I receive one yesterday and open it today. Please carefull ! ! ! The power contacts do not switch at the same time - both sides ! ! ! So it is possible for some ms is power on zero line / the equipment. This is dangerous.
@@2012SUSE Thank You for Your answer I decided to use manual switch with neutral.
@@2012SUSE Hi - thats allso one of my biggest worries about this units - that for example 2 phases are connected and no zero line ... im searching for a good automatic Transfer Swich since a long time ...
@@GTRDRIVER1 Did you find one?
@@UmarFarooq-jn7dt no only junk
30ms would not shut down a computer. The PSU discharge isn't THAT low. It takes around 1-2s to completely discharge the PSU of a computer. It would indeed work for like a switch between solar, and grid power. Love the video though and very informative, thank you!
What would be good one thats certified for the US?
I cant seem to find ANY! Just very large ones.
Not from us so cant tell :(
So it's no chance to set "B" source as primary for full automatic? always "A" source is primary when I have to use full automatic switch betwen A and B, because when I connect my control wires only on the B side source "A" no switching, when "B" source gone, right?
Of course you can, it's purely how you wire it.......if you wire grid as A then grid will be your primary. If you wire grid as B and solar/wind/gen as A then the latter will be your primary.
Thank you for making this video! Do you know any ats that will not shutdown a computer?
Its not the ats that is the issue. The problem is what you have on the inputs. Are the both inputs synced or not as example.
@@DIYTechRepairs sorry im new to this electronic but what do you mean by unput being synced? Input like solar panel and grid supplying power to the inverter? Im using a deye hybrid inverter but when i turn the grid off, the inverter is not able to switch fast enough. The computer loses power.
@@walterrostangarciajr you need a different inverter or you can add an Ups for the computer.
you can ignore the pictures and use it the way around
one thing i'm worried about. neutral breaker should connect first and disconnect last. if not, your house neutral will float short period and overvoltage in some phase(s) vs. floating neutral may happen.
Can't be done with a 10ms ats. The breakers also only break the hot lead. That is what you have the rcd for. It will break neutral if the current doesnt add up
Get an UPS for your computers that are sensitive
You need an online Ups. The cheap ones generally below 2000va also uses mechanical switches that can cause same behaviour as above.
Dont forget that :)
@DIY Tech & Repairs Add one more thought with this one, if only S or T phase fall out, then you sucked, because never will switch over, since only observing R phase.
Correct
Hello, im thinking of buying this but im gonna have a pure sine wave inverter hooked up to the backup power input and normal home power hooked up to grid input and i will have 500w load do you think my computer will turn off when the transfer switch changes from grid power to generator power?
It will work fine. I do it like that.
@@DIYTechRepairs Okay thanks buddy
Is it possible to attach a remote switch to cut over from A to B? What I mean is it this is in your garage and you want to switch it manually from A to B into your living room Can you attach a manual switch with a wire to it?
You Will need to rewire it to do That. It does not have It per default but It is possible
Can a ATS like this he made to switch from one service to a second service? I have two services and I want the lower price service to be used in certain hours (off peak) and the higher price in other hours (on peak).If not what kind of a switch would I need to automatically switch during certain hours.
ats switches when primary power fails (no power ) then secondary power kicks in and when primary returns switches back
@@josephrosa5845 If using a transfer switch with control lines for each power source couldn't you
interrupt line A and the power line B with power maybe with a short delay. In this control circuit
you could have timer for when each circuit is active . The relays in the ATS would only allow
one power supply to be on at a time. Maybe I do not understand how this works and would
appreciate any help any one could provide. I am trying to power devices for a certain time on
2 different electric power services to be able to take advantage of the lower off peak rates on
1 of the services. The ATS would be mechanical device to prevent both services to be connected
at the same time.
Joseph are you in the US?
@@firstbigbarney
Can we understand you, you have two sources supply, A & B. You want to switch between A & B based on the time of the day? Perhaps,
00:00-12:00 on line A
12:00-23:59 on line B
Or you rather want to switch based on the supply voltage value? Like,
When Line A peak voltage is less than ## Switch to Line B.
Please clarify.
@@nyameamah That's exactly what I want to do I want to switch from one meter to another meter which is an off-peak meter at certain times to buy power to charge my electric car. Can I interrupt the service from circuit A with a relay and a timer to be able to engage circuit B ? I thought this was a good solution because you have a mechanical interlock contacts on inside of the ATS and you also have a high amperage availability on these units. If you interrupt the control for circuit A and make it make it look open and it'll switch to the circuit B with a delay would this be possible? After the timing interval on circuit B it would open the control circuit and close the A circuit enabling the original A power source again with a delay for safety.
This would happen daily according to the schedule for your off-peak power currently ours is 2300 hours to 0700 hours all 7 days.
Thank you for your reply. BigBarney
@@firstbigbarney
Did you find out how to fix the problem with your power changing?
Hi have a house with, 3Phase, Sungrow SH10RT 10kW Hybrid inverter and
16kW Sungrow SBR160 High Voltage Battery Modules , would this ATS works for my house battery system or, this is for the small solar caravan system?
Thank you
It's a 3phase 63a ats
❤ Thank you so much, it's perfect for me then.
Har kikat en del på denna också men är lite osäker på kvaliteten, finns det någon godkänd du skulle kunna rekommendera?
Schneider har ett par. Men ja ovan är kanske inte svensk standard. Jag har kört med min i ett par år och än så länge funkar den.
Hello dear , thanks for your video .. sorry for my bad english... i whant to buy one to use with my genset... but for me this switch can’t work because the backup power source is off during some minute during the time for the engine to start... when the grid powwer is off without any power .. how is the switch positione? Or maybe the position of the auxiliary contact...
Thanks for your help...
Not sure i understand. It wont switch unless Power exist.:)
@@DIYTechRepairs do you hace try to conect only the main power , without backup power, and try to turn off the main power? What is the switch reaction??
@@DIYTechRepairs thanks for your reply 😉
thats what no/nc /c connections are for
@@josephrosa5845 hello , i have recieved the product... yes your right about no nc contact.. some other ats work with build backup supply
Pls, does this device have the gen-set remote switch capability?
No
thats what no/nc /c connections are for
One thing is not clear for me. I have already setup circuit with breakers and everything. How I can switch those for different output eg solar power when both of them are active at the same time?
you cant have both inputs active at same time to same output unless they are made for it. An ATS switches source to the output and is often connected befre for instance a breaker panel feeding it
don't use tape, unplug the mains and work offline. also heatshrink tubing I prefer more than tape around a screwdriver
Of course you unplugg as amateur :) heatshrink is Good advice
Always use electricians fully insulated screwdrivers
@@mrfixit100 the already made ones yeah, just don't use bare metal ones at least.
Hello I have a problem and I need your help. This ATS has a switching time over 10ms. Everything under 10ms is ok, from 10ms I have the problem that certain devices can be destroyed. Therefore, I would like to switch a switchover delay using a relay. How do I turn on the relay on your device? Do you have a schematic
You cant get it to switch much faster to be honest
Most switches are 10-20ms delay. IF you need faster put an online Ups in between or buy a more expensive switch.
What is it that cant tollerate 10ms?
@@DIYTechRepairs missunderstanding? i won´t faster, i want a delay relais to protect the devices. How can i turn on a delay relay on this device?
@@diy-powerwall2729 ahh sorry :) you cant with above unless you open it Up and modify it. Its better to get contactors with interlock that you yourself build the Logic around. Look at My earlier videos :)
you want longer delay just add a timer.
Hello - i want to ask you if you have installed this Transfer Switch and if its still working fine ? - the Video is now 3 Years old so perhaps you have new Information about this switch ... - My biggest worries about this switch are the Svrew Terminals they look very cheap ....did you use ring terminals for the Wires ?
I run it still without issues. No I use standard cables
@@DIYTechRepairs Hello - Thanks for tast reply - Thanks for fast reply -- im also a little worry about the switching time and the possibility that the Neutral Line is not connected at the same time then the ofter Phases - 2 Phases and no Neutral Line is a very bad thing for all the Electronics ... - But first of all - Thanks for fast answer and have a nice day !
Hi, I have the exact same model. and I have one issue with this. For the backup power connected to a 2000w modified sine wave inverter. When the main grid power goes off, The ATS has to transfer for the inverter power. but instead, I can hear a relay buzzing sound from the ATS. tries to switch to backup power but it doesn't and make buzzing sound continuously. I check inverter It can handle 800w grinder. How much amp ATS relay using ? is there any solution for this.
I tested it use 1.9amp to change from a to b 120v
Did you resolve your issue or get a different ATS? I am wanting to use a Projecta PW350 inverter as the main input as I have solar power which is rather use but automatically switch to mains power if the battery gets low and turns off. Thanks.
probably because it's a different wave form so the ats doesn't like it and doesn't switch completely.
Hello Apple Tree, I have the same issue, how you can solve it?
Thank you very much!
@@victorhugostosius5245 I replace with with 4 pole relay. I have low load. Bt u can use 2no 2nc contactors.

Jotta is a bit cheaper but Geya has a CE certification.
I checked their MCB's:
Jotta has only CCC for China.
Geya has CE for Europe.
In case of fire, your insurance can refuse to pay and get away with it if your equipment don't have CE.
There is cheap and too cheap.
interesting but ithere is no off position if no power on AR AN and Br BN i want to out over and under voltage relay on both source A and source B but even if source A voltage is low the load will jave the voltage unless i put a contactor on source b and source A so this way no power comes in and to load unless voltage is good
Its just an ats
Its either or :) for what you search for i would build a custom cabinet with ats and then contactors.
@@DIYTechRepairs i know but lets say source A was off no source b so it wont change and suddebly source A back again ur load will have power no matter what over uner voltage relay u put in series from source A phase to AR unless it switch tonsource B even no power source
@@DIYTechRepairs it wont switch to B cos there is no power on B yet generator still off :)
@@andrekhoury6252 i dont understand? It Will priotize a and IF a doesnt have input it go to b IF it have. Its a solar system ats. You can Always add lvdc in front of THE sources.
donu recommend it for 65 amp and to get the 125 version since on aliexpress all same price
Is the "primary is primary" problem all that bad? Just wire up what you want to be primary on that side.
Sometimes you want to change it. Example i Winter i run grid as primary and during Summer solar :)
Where i live sometimes the power flickers on and off several times before it get fully on. It would be nice to just pull a swich and have it wait. Or even better, a automatic timer giving it 5 minutes or something before swiching over.
@@matsv201 Some smarter ATSs have configuration options for that.
@@jmonsted That is true, but the genearly cost a bit more. I´m really not that cheap, but some of them tend to be a bit to expensive for home use.
I really just need it for a few computers and some other stuff, most of the lighting is already DC.
@@jmonsted I just saw a indian guy, simply putting a cheap relay timer between, that was really a very clean and simple solution
On some of the aliexpress pages is noted: "NOTE: The rated voltage of the common and backup power supply must in range 85%-110%, and the current cannot be less than 5A, otherwise the coil will heat up or even spontaneously burn. If your city voltage not stable, please kindly add voltage protectors in system." ... So one would have to run at least 5A through the device ? Sounds a bit odd ..
They add what they can to protect their products that is badly designed i guess :) To have a minimum current is just like saying you cant drive your car below 100mph because then it will blow up. :D
I think because it dont have any logic circuit with microchip and its just analog think.. The higher voltage will overload the circuit inside and burn the coil, components and low power can disable the function of coil and then it will not work at all.. So if you live in modern country where they keep the voltage same all the time you are good..
what would one use for a server solar setup no battery?
Grid? You need either grid or battery. Can't use solar only since the sun goes down or behind clouds.
@@DIYTechRepairs trying to do a grid with solar switch, just cant have a delay.
@@SynthToshi no you do grid tie where the appliance use the grid and then the solar sell back to grid. As said you can't or more should not run on only solar because solar need a backbone lite battery or grid
@@DIYTechRepairs so what solution are there for a switch for servers.
@@SynthToshi any ats or powers powerswitch. Like from apc
There is no 0 zero position
To off both the grid and solar
You dont mention operating voltage IMHO given the contact separation ca 30mm? its good enough for up to 24Vdc 100 A but I wouldnt trsut on a 48V system, much bigger gap, or a proper magnetic arc quenching shute like real industrial breakers from Siemens - Google the internal construction and see why. Otherwise make sure you have cable cutters nearby when the arc doesnt quench. Plenty of YT vids to show what can happen
Why dc load? They are built for switching ac load.
Try with load
@@DIYTechRepairs Well does it work or does it not ??
@@iwontlagback7236 the device itself works. I'm running it
i wouldn't go above 10A

What parts?

If you really want to get your system or your house up in fumes, go for it. I'd advise you not to use it✌
Please tell whats not Good about it. Because i doubt it just starts to blow Up without issues :) i would Love to have more input from People actually used it
@@DIYTechRepairs take a look inside it and you'll see how frail it is. Also if it locks in between changes I'll heat up so fast that if you not around you could have serious problems.
