Sun 2000 GTIL2 Inverter full test. How it works, what it does.

Please be careful with this device and follow the local regulations for grid tie inverters in your country. This is just a test I'm doing, not a final installation and everything is safe and isolated
Today I'm testing the SUN GTIL2 Inverter with 2kW on my workbench. Before some will leave a comment, I'm not recommending connecting this inverter via a GPO, power outlet or power point. I also know that the inverter can feed-in a small amount of power even the limiter is set correctly. The same can be said about Victron inverters which are far worse than this inverter in this regard. When a load is turned off and the inverter ramps down it can occur, that power will be exported for 1-2s.
We test, how the inverter works and how the power output can be limited, either fixed or automatic. I show how the limiter clamp is working and walk you through all menu options (which are not many).
You can find the SUN Grid Tie inverter with limiting sensor in the 1kW and 2kW version here:

Great inverter, I have one too. For off-grid you can use the Victron to fool the GTIL2 into thinking there is grid power.

The idea of this limiter used in this Grid tied inverter belongs to Rogel Naval a Filipino Engineer based in Manila. He had this made with masspower in China. It's called Grid Tied Inverter with Limiter or as we know it as GTIL. It's first version has an external limiter which is now phased out, what you see here is the version 2 that has an internal limiter. I had both versions and the version 2 with 22v-60v runs on 48v LiFePO4 batteries. Simple to use. Greetings from the Philippines 🇵🇭🇵🇭🇵🇭

[@benkanobe7500]

This is the best explanation of how these work on KZbin. Thank You. I have a question: If using batteries (I assume for after sunset) with only a maximum of 1000 Watts of daytime solar, would the inverter be able to recharge the batteries if they ran all night supplying 1000 Watts to the house and still be able to provide power to the house during the day or would it need to be dedicated to just recharging batteries. I am a little confused on that part.

[@OffGridGarageAustralia]

This inverter does not have a charger. It's not a hybrid inverter. It's grid tied with power support. So it will deliver the energy used by your load as long as possible until the set low voltage cut-off is reached. The grid will then deliver the energy again until the voltage in your battery rises and the SUN takes over again.

[@benkanobe7500]

@@OffGridGarageAustralia I am doing a bad job explaining so thank you for continuing to answer my dumb questions. If I want to take advantage of my large battery bank (AGM) at night, do I connect my panels to an appropriate charge controller that is then connected to my battery bank that is continuously connected my inverter? I would set the inverter to cut off at 37.30 or so VDC to be conservative to my batteries and then the inverter would restart in the morning when solar made voltage climb to set level?? I think you see how I want to use the inverter. Am I doing it correctly if as described above?

[@OffGridGarageAustralia]

@@benkanobe7500 no dumb questions here at all. How you describe it here, that's exactly as it should be, The inverter should turn off at a set voltage to prevent the battery from being discharged further while the BMS does not trigger in this case and still acts like a safety switch to protect the battery if something goes wrong. Perfect setup.

[@5UPRAH]

@@OffGridGarageAustralia I'm a bit confused. As this has a MPPT solar controller, if you have a battery bank that you want to use with this, you would not be able to use the MPPT solar controller from this inverter?? Would the set up be - Solar Panels to Solar Controller to Battery Bank then from Battery bank back to Inverter ?

[@michaelwyatt-k1o]

Gday Andy. Choose between the gti2 or your deye microinverter for ease of use and longevity? Great videos by the way

[@OffGridGarageAustralia]

Thanks for your feedback. The GTI2 and the micro inverter are two different things. The GTI has the major advantage of having this export limiter, So depends on your situation and system design which one to choose.

[@eliatasti06yt]

20:43 European here. Wait a second.. in Europe sometimes we also use the current limiter included in the box of this exact inverter. In Europe, by law, we can output to the grid (with this type of plug-and-play inverters) a maximum of 800w (in some countries is overruled at 600w), and exactly because of this we use the current limiter, it makes us able to have bigger systems without breaking the law.

[@GlennRathke_WX]

That is good info. Too bad that setup does not work for us in the US for the 2000 watt model. We need to monitor both legs of the split phase with the current limiters.

The battery have a Dishcharge Volt at 44.5 ~ 53.5. In your opinion is the right configuration?

I wonder how can i cool up my 3 x 2KW inverters. A. Should i place a timer so from 11 mid day up to 14.00 to have a break and actually cut the input power of the inverter???do i need to cut only the input power or do i need also to cut with a rele the solar voltage that feeds the inverter???? B.Shoula i place a 7000 btu aircon??? from a wheelhouse that i have???Whats your opinion please.Thank you Very much.

[@ranelalvarez]

Question, what grid of power is the power supply that you use comes from, is it the same grid that you use to power ON the lightings that you are testing?

[@Grangeno08]

Great video. Do you know if the neutral and ground are internally bounded in the inverter? Thank you

[@OffGridGarageAustralia]

No, they are not bonded in this inverter. That would be fatal. The MEN link is in your meter panel or distribution panel. It is only inside an inverter if it is an off-grid inverter.

[@malquezare]

For normal use it's better to use fat cables to use with the clamp it gives best readings

[@_HashForce]

excellent video thank you!

[@MichaelEricMenk]

30:50: " it is not a off grid inverter" Thia inverter can most likely used in a off-grid settings, with the sensor. The sensor makes shure there is no need production, and thereby supporting the inverter. I saw a video where someone had tried connecting a grid tied inverter in parallel to a off-grid inverter. It worked well, until the usage was below the production of the grid tied inverter. The over voltage destroy the off grid inverter. But here that clamp will most likely prevent that outcome.

[@davecollier8946]

The remote number is for the rs485 identity. If you change it the wifi dongle Will not work. I am trying to control the export with a raspberry pi. However I do not have a clamp do you know what the voltage or preferably waveform looks like. Also if you press and hold the top 2 buttons on power on you get the firmware menu. Thanks for clarifying the reboot voltage now I know why it only kicks back in at 27 volts. Mine is just for controlling a wind turbine. Thanks in advance.

[@OffGridGarageAustralia]

Thanks Dave. I'm not sure about the CT's specs but you can buy them online for around $50.

[@harrycrawford8517]

Hi Andie, really enjoyed this video the device is very interesting and is pretty much what I have been looking for for quiet some time. One additional test I would like you to do if you are willing? Could you test to confirm that the inverter will not back feed power back into the grid if the grid goes down? You could simulate this by unplugging your RCD or power meter at the grid end and then testing to make sure the inverter goes off and there is no power on the exposed pins. This is my only worry that in the event of a grid power failure the workers that come to fix it could receive a shock from power being sent back into the grid from the inverter.

[@john_in_phoenix]

This is the reason it is not legal in most countries. The certification is mainly to protect the grid and anyone working on the grid. It is an expensive process to get certified. Personally I would not hook one up, simply because without the grid in the Phoenix area, your house would uninhabitable for many months of the year. Make no mistake, our meter reports hourly to the power company, and they will be able to tell if you hook one up.

[@OffGridGarageAustralia]

Harry, The inverter will turn off within 25ms if the grid fails. 30ms is the regulation in most countries. It has anti islanding function, so will not stay alive if the grid fails. It's a grid following inverter.

[@pkuudsk9927]

Could you please tell me if this would work with a 600 w windmill and a 100w solar panel.? Edit not how well or what to expect ... Just would this work

[@stephenbuckley2186]

nice, I have a wind turbine hooked up to mine and I am a bit reluctant to use the limiter cos I dont know what happens to any excess power produced. I assume it goes into the dump load (no batteries) but if it doesnt could it unload the turbine? which would be very bad.

[@OffGridGarageAustralia]

The inverter for small wind turbines usually need this dump resistor connected. Does yours have this?

[@stephenbuckley2186]

Yes, although the one that came with it is 10 ohms and the one recommended by the turbine manufacturer is 4 ohms which I do not have. Any idea who to contact about the inverter as it has a blue internal light flashing about once a second I have another in which the light is steady and assume a fault of some kind but can't find the manufacturers to ask.

Hi there Thank you for the great video! 🙂 I do have a question that i hope you can help me out with. 😬 In your video at minute 12:13 through 12:25 , it shows that you have 53v comming in the inverter but your watt production is at 0.0w. You say it is on stand by. 🧐 How do you get out of stand by? 🤔 I am asking you cause, i use 2 of the same inverters but for wind turbine and even though i feed them with 53v or even 58v (depends on the wind) both inverters are never producing any power! I am getting really disappointed in the whole system. 😕 I thank you, in advance, for your time and answer.

[@josipkubasa4944]

Hay Andy, I have some information for you... I have two inverters SUN2000gtil in last two years. If You develop your project about this inverter.. you will doing big mistake. I will explain why.. 1. This inverter is declared 2000 W but is not... Today this inverter product only 1200 W depending on environment temperature. I must set limitation of production to 1300 W. If is setting for limitation of production 1800 W ,then inverter is overheated and automatically limit power. On the end go to turn off. 2. One inverter was burned on and not have any option for repair it. I was buy second and on this inverter burned two small fet transistors for controlling fans. In this situation I was repair it. 3. This inverter have price 300 to 400 EUR (depending on the action). Two inverters in total 2500 W cost about 600 to 800 EUR-a. I think.. that is to much. 4. Inverter have very poor interface for monitoring. Addition problem with interface is.. when doin connection and read data, inverter stop working to one to two seconds. Real data is not real... this data is average in 5 minutes. 5. Warranty basically not exist.. 6. If you use battery, must buy two addition MPPT. Ok.. you have chargers but this price must be included in total price. I tings... more better option is buy inverter with all in one... Inverter with two mppt-a, Warranty 5-10 years and good interface to managing and monitoring. For example: Groowatt SPH series or GoodWee residential inverters. Both inverters have option for zero export which is controlled with smart meter or CT clamp. Inverters have connection to battery BMS an can configure point work for battery. SUN2000Gtil is good budget inverter for starting with solar experiences, but is not good for your project. I have plan to replace this inverters with Growatt SPH 3600 for which price is about 1350 EUR. With regards. P.S. Sorry for my English ..

[@repairman2be250]

Noe need to be sorry for your English at all. I agree with you not on the basis that I have actual facts, but on the basis Chinese product specs are in my opinion just half the values they advertise. So, a 2000W device is only good for about a 1000W. Forget about warranty, it might cost you more to ship back to China.

[@OffGridGarageAustralia]

Depends on which model you have. There should be a label on the side with the information you need. The one I tested went from 40-90V input voltage from the solar or battery side. The higher the output, the more amps it pulls from the battery.

Here in the U.S. I found that my limiter sensor was showing minus on the screen because the prior home owner had incorrectly wired the electrical receptacle (power point). They had wired the neutral to the hot side and the hot line to the neutral side. Appliances will work with such incorrect wiring, but there is a risk of an electrical shock. So, I rewired the receptacle and the minus went away.

Any feedback would be welcome. My BEV can support V2L but not V2G, my baseload required with fridges running is around 435W. So I thought about connecting my BEV to an AC to DC variable converter and setting the output to 90V at 6 Amps. This would then be connected to the SUN inverter and then fed to a dedicated 15A circuit in the meter box with it's own separate RDC and Circuit Breaker. I can't see why this wouldn't work.

Bought 1 one year ago, now i have 3, each for one phase. Using it with solar to charge battery and this inverters connected to the 14s Li-ion battery. They work really nice. I recently added wind turbine aswell ;)

[@OffGridGarageAustralia]

Thanks for sharing. I'm interested in a wind turbine setup myself. Not that we have super high winds here but from the general perspective and how it would integrate.

[@wootdeco]

I used three phase bridge rectifier connected directly to the inverters(since they already have the capacitors to do the smoothing) and for brake i used arduino to check for high voltage and set pwm signal to do the braking on ssr relay connected to the heat brake depended on the high voltage. But so i don't discharge battery i used one diode in bettwen so it actuall brake the turbine and not drain battery. I coul use the controller that came with the turbine but i read that they fail on high winds (which i do have sometimes).

[@DanielSan-ch7dr]

@@OffGridGarageAustralia the newer turbine don't need much wind like a 9blade one. It might not be windy on the ground but you put your wind meter or turbine up about 40ft and it's alot stronger then ground level. A turbine works better when the solar weather is poor e.g. wet windy stormy teribble for solar but great for wind, wind blows 24/7 so the decrease in performance can be made up with increased run time.

[@OffGridGarageAustralia]

@@DanielSan-ch7dr We have like 130ft trees around us so I can see how the wind situation is, direction and strength. I might try it at some stage, but it's a lot of effort to put up the mast, make it all secure... we will see...

Muito Bom!!!! Tenho um inversor grid tie limiter de 1000W com 2900Wp em paineis qual o valor maximo de potencia eu posso ligar neste equipamento

[@jozefstilec1524]

Hey Andy, thanx for realy great videos. You have made many of my days :-) Just one question regarding SUN 2000 or 1000. Normally at the manual SUN is prohibiting to connect two invertors on one PV string. Understood. But teoretically connect two inverters on one battery bank should works. Am I right? or not. Thank you for respond or help.

[@OffGridGarageAustralia]

Thank you Jozef. Yes, that is correct. You can connect as many of these inverters to one battery as you like and parallel them to increase output power.

[@alets9788]

Andy I appreciated your beaviour. It well done aproach. Fast easy clear answer. Sorry but next question. I have went through of your videos and looking for right answer about the most suitable BMS for EVE bat cell for example. I have seen your hard execsising with Daly. JK and QUCC xiaoxiang better but I could not find right answer which one is most suitable for. Would be great to get your opinion for the most suitable BMS with EVE or others bat cells. Thx and keep fire burning. Go ahead as till now or even better

[@OffGridGarageAustralia]

@@alets9788 thanks you for your comment and question. The best BMS so far is the JK-BMS for all batteries 8s and more.

SUN-2000GTIL2 Does not save settings. Changes in settings, default to YES, and Press setting button does not save. Any ideas? Is there a factory reset on these units? Thanks for the help.

[@stevenpleasant5834]

Hi, glad I found your channel great info this is helping us with our off-grid setup I would like to ask if there might be a way you could send me a copy of both of the instruction manuals so I could study the wiring setup. to learn and see if we want this kind of inverter thanks.

[@ardehshir4590]

hi there, I have 2kw 45-90v Wind grid always show voltage to low ,do you know what dam setting I should do? many thanks

[@xtremeaerialvision9413]

Hi Andy, do you know if the limit sensor is bidirectional? As I have two systems and only want the battery one to produce power when the other one (non battery) stops feeding the grid.

[@honeybadger6127]

I've been running mine for about 3 months and now it won't go over 950W.... any idea what I should do to troubleshoot?

[@stuartdavies8388]

I've just purchased the 2000w with limiter for use in my shed, here in England. Fantastic info, thank you..

[@repairman2be250]

I am very concerned about the build quality in terms of the power rating. Many chinese products don't live up to the specs. Der Kanal has had some in for repair with and without success in fixing them.

[@zuutube875]

Stuart mate, I've just bought some panels and so now looking into grid tie inverter, do you use just solar? Or do you use batteries aswell?

[@daniellang8683]

@stuartdavies8388 how is the inverter holding up?

[@eamonhannon1103]

The have a power limit . I would like the inverter to regulate the input dc voltage not the power . With this mode you could set up maximum and minimum dc voltage and the inverter would regulate the dc input to keep the voltage inside the user defined limits . Can this be done ?

[@elbuscador2393]

After two years of use, it presents me with a grid error, and I don't know how to correct it, technical assistance is needed from the manufacturer or I already consider it within the disposable Chinese products.

[@ghazwanabdal8111]

I am from Iraq I bought one from Amazon, mine does not working what ever I tried it does not work. Is their any way to or guild line to connecting in right way.

[@antniocris9744]

Here's a trick Put two Coil taps one on each side in USA cut wires put them in Series! Now it will read both legs instead on one! Now we just have to figure out how to make these last longer then a year or two.

[@SnowingNapalm]

still watching video and trying to like again 😄🤣 at least 3 times while watching but already liked so it wouldn't let me add another ❤

[@maxusboostus]

I've just had solar installed and they have connected the inverter direct to the grid side of my smart meter so i have to pay for all the energy I use. I asked why and they said that if the inverter was connected to the house mains and I used more than it was producing it would cut out.

[@stevenpleasant5834]

Hi, can you do a video on your other inverter in your shop I need an off-grid set- up even though this is a good video too on this inverter thanks for your help.

[@kathyshepanski5002]

What are you using for a WIFI connection? I'm Interested in monitoring from my cell phone.

[@W122ard1]

I have same inverter but my field "cut off voltage" is greyed out, so i cant even choose it to change... this is strange.

[@jcadag8789]

Hi! If I install the limiter sensor, I should also turn on the internal limiter in the menu to make it work properly? Or just leave the internal limiter off in the menu? My electricity provider does allow me to export electricity. I'm ordering one just like that in 1000 watts in either 22-60VDC or 45-90VDC depending on how many 100 watt panels and in what combination of series or parallel connection . Thank you for sharing and posting and these vids are plenty helpful to my project.

[@OffGridGarageAustralia]

You only need the limiter if you want to limit the power been exported or prevent a feed-in altogether. Otherwise both can be turned off.

[@yankeered5625]

The black wire is the active one ? 😂 great information definitely would me on getting 1 or 2

[@jameskim62]

How is the unit workout ? Any problem? I am thinking about buying many units.

[@rOSScOGITANS]

Hi Andy! big hello from italy! just an ask, what if i'll give the grid to another bigger inverter (with no limiter functions) from this with limiter (i mean to connect the AC output of the sun gtil2 to the AC input of another inverter)? the surplus energy of the main inverter go back to the gtil2 and what will happen? shoud be a trick for have limiter function to an inverter that don't have it?

[@OffGridGarageAustralia]

Hi Ross and hello to Italy. That is a bad idea unless the 2nd inverter is a Victron Multiplus II or Quattro which can handle AC input from another inverter.

[@allzzizzwellzz5841]

can i connect 48v 800w wind turbine via charge controller or rectifier?

[@usuariouser224]

Dont input 180v series of panels .never. It has burnt

[@pkefvkef4856]

My dear friend.Can you be more specific for the efficiency of the 2kw sun grid tie inverter...If you want my experience offering him DC panel power 2000 watt it gives me no more than 1450 watt.so increasing the panel power to 2850 watt v=85 volt and I =35 ampere DC. THEN IT GAVE ME 1850 watt....so 1850/2850 = almost 66 % efficiency......i am really curious for yours measured efficiency......thank you .

[@pkefvkef4856]

Dear friend are you kind enough to say a few words of the efficiency of this so well presented grid tie inverter.Because as i mentioned with proper instruments i measured the DC input power to the inverter and in order to get 185o watt AC i had to connect the maximum input power it can receive which was 2800 watt.which in a way gives an efficiency of 66%.Meaning you give to the machine 100 watt DC power and you get 66 watt AC. Which means they say is 2 kw and never gives 2 KW.If i make mistake please correct me with video.Thank you.

[@Pyper80]

it is possible to connect a storage battery to this inverter adding a charge regulator?

[@R906-d9l]

i have a pair of 1000w sun inverters with LIMITERS and now have a 48v battery, noticing that switching on n off high load, the inverter shows NEGATIVE watts for brief period......any thoughts or have you observed this phenomena? i live in california

[@OffGridGarageAustralia]

Yes, that is normal, it overshoots for a sec when load is gone as it needs time to ramp down. Same when connecting loads, it always is a bit behind.

[@dredre9484]

Lol funny story showed this to my dad (his a consultant engineer)had him so convence in this until he found a flaw it's not Australian certified so I'm spewing this would have worked so well for my boat charger lol does anyone know how to certify products in Australia as this is a awesome producton (only reason I mentioned this in Australia if it's not certified and it causes a fire insurance won't cover it)

[@OffGridGarageAustralia]

Yes, that is correct. I tested this device to show the principal of how easy it would be to have a viable solution from a technical perspective. I've sent them both back now... and keep looking.

[@martincross823]

Thanks great video, have a question. I am in the UK where the Neutral is bonded to earth. If I add mcb and rcb between the inverter and my house mains, will the rcb work? Will there be any problems with grounding?

[@OffGridGarageAustralia]

We have the same MEN link here in AU. Yes, RCD will work just fine, no problem at all. Consider using an MCBO (MCB and RCD combined).

[@jimshepanski7339]

[@rbosburp6540]

Dear Sir, I have a small question related to this 2000W SUN GTIL2 inverter. My solarpanels are CanadianSolar with each 455 Wp and these specifications: PMax: 455W; Imp: 11.02A; Vmp:41.3V; Voc: 49.3V; Isc: 11.66A Since the input voltage should be between 45-90V and in your video it shows that it "kicked in" at a little more than 50V I don't know how to connect the panels to the inverter. How many panels can I connect and how many parallel, how many in series?

[@OffGridGarageAustralia]

The inverter can handle a max input voltage of 90V. So the panels you have are not suitable for this inverter.

[@rbosburp6540]

@@OffGridGarageAustralia Thank you sir. That's too bad, because it looks such a nice inverter and you explained it so well. Next time when I add some panels I make sure they are not so big and I can use this inverter. Thanks again. I also subscribed to your channel, because you have many interesting videos :).
