- 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.
I will use this sunny day to test the SUN GTIL2 inverter with direct solar input. The inverter has a build in MPPT solar charge controller an can take panels with a maximum voltage of up to 90Voc. How good is the solar charge controller, does it track correctly and how much output do we get on the load side with it.

I bought 2KW SunGtil2 and it just arrived today together with safety devices. Panels are on the way. This is my first time to assemble it myself so i have to watch as many tutorials from youtube. And all your videos really help me. Regards from Phillipines!
since i found your channel i found out i'm now addicted to it, learn so much and forget so much more, but keep it coming, i love it. thanks.
Thanks, Luis. Also for the donation!
with 2 panel in serie, you can't have more amps than the smaller can generate
A new video, instant happiness!
Hahaha, thank you.
I've watched all your newer vids, so now im going back in time to watch your older vids 👍
SPAT I call it solar panel angle test 🤣🤭 close enough tho 👍 I use small blocks of off cut wood to do mine 😁
Thank you for the entertainment and very helpful info 🍻🍻
love your video and REALLY love the sharing of your tools list - super. i tested the GTI2 1000W with 4x100 W panels and get 88% efficiency between DC in and AC out (ACout peak 300W)
Thanks for sharing, Erhard. 88% is not too bad for such a cheap inverter.
Thanks Andy
Calibration for my beards consist of a temp of 33 deg F, label out and at least 1/4 space in between him and his friends. As another mentioned the minute I get a notification of a new video from Andy my day is suddenly brightened and I yearn to go home and play with batteries, cheers (in few hrs) my friend
Thank you very much. I'll make more videos then ☺️
Beau test ! Merci
very grateful for the great video I learned more about this equipment I also use Canadian boards.
congrats on the ponies they are beautiful.
Thanks a lot for your nice comment! ❤
SUN Grid Inverter GTIL2 60-110 volt/2000W, 2 sharp 440 w in Serie . Mit dem wifi Dongle und dem Shine Monitor hast du "a lot of fun". Schöner Kanal ! Grüße aus Deutschland
Hallo, kannst du mir sagen welchen wifi Donald und Monitor du meinst. Thanks
It is a very capable unit.
Öttinger Kalibrierung wie geil ist das denn??? Ich mag deine Videos!!
Great machine. 🇬🇧
Hi, thank you very much for your videos are really great. I like your enthusiasm. Involvement of animals as a rest. Thumbs up hard.
Thank you very much!
Thanks!
Thanks a lot, Tony.
Great videos, don't forget that when using mixed panels in series ie a 215 & 220 = 2*215= 430 Watts DC. Shade just one and it may equal 2* 100 watt panels.
Yes, as we have seen with just a tiny bit of shade on one, both panels didn't produce more than 100W together.
Thank you man! 👍🥸

Morning Andy, you are probably at work or Locked down at present. I stuffed my back last week moving boxes. So vlog will be slow on my channel for a while. Good show as all ways.
To calculate the correct series power of 2 panels in series, add the measured voltages from your solar panel tester from each panel and multiply that by the lowest current measured of the 2 panels. Thanks!
Yes 👍 🔌 🔋 ⚡
I love the sonoff products
Thanks for showing the animals.
Any time, I'll bring them in from time to time to mix things up a bit.
very nice Schraubendreher. Bitte immer so weiter machen. Gruß aus Gommern.
Danke Dir!
Thank Andy
Very welcome
Hii, I love your videos and details! Thank you. Really amazing. I am wondering what is that device you used to test the solar panel wiith the "AUTO" to test panels? What is called? handy to test solar panels.
I just put a 48V battery bank on this and cap the power to 1kW it does a great job at it
Ive been trying to figure out a resolution for my situation and if I'm understanding this correctly, this is the key ive been needing.
Have Mains Utility with auto transfer switch to propane whole home generator. Seems this is what I need in contrast to the micro grid ties since this will not back feed and excess the grid and I don't have to do some other fancy multi position transfer switch. could put one on the east side of the house and one setup on the west side and be able to offset usage. I work from home so my usage drops at night.
Wonder to know if you can connect small windmill thru rectifier bridge. Any idea.
Thank you.
Im liking that inverter!!! May have to pick one up! Ordered one of those fancy 40a battery testers! Should be here soon!🤘
Hi Joe, I like your inverter more, but it was a big struggle to get it on the wall :)
We need a 4 month inverter review if you ever make another video...Boom .lol
@@wayne8113 Yeah HUGE strugle to mount that guy lol!
@@onthelake9554 I need to upload for sure! Work has been wearing me out! Inverter has been working great btw. Few fanlock fualts but the firmware upgrade will fix that whenever I get time to do it!🤦♂️
Hi There from the USA, Nice Vid, if I get this straight, I can limit the back feed to the grid
with the limiter
so its not apparent that i have a pv system at all
Thanks
Thank you very much, Luis. Much appreciated!
Is the plug provided suitable for Australia or does it need to be modified? Thanks
Hello Andy, do you have a video with this inverter and panel and batteries plug in the inverter?
Hi Andy, love your videos! Thanks so much; look forward to seeing them everyday. Question: where I live the power company does not allow you to feed power back into grid. They are concerned that when power goes out and line workers go to repair that they could be killed if you are feeding power into grid. I noticed that for a brief moment that your set was feeding electricity into grid until it adjusted. Is that a concern when electricity goes out and line workers start repairs?
They only operate when they see the grid. Disconnect in milliseconds when the grid fails.
Greg, that cannot happen. If the line workers turn off the power, all inverters will turn off immediately within 30ms as per regulations. It's called anti-islanding. They will not stay alive just by themselves.
i bought 4 have one left they didn't last long...1-2 years, could be power spikes in FL.. ?
So I have one of these gtil2 2000w inverters coming soon, operating voltage is between 45 and 90 volts
I have 5x300w panels, max power output is 37 volts and open circuit is 45 volts per panel, am I right in having 2 panels in series and the rest in parallel?
Could this be used tp power water heater?
The 420 watts total is @ lab lighting conditions. Usually panels produce around 70% of their labeled power. You should get about 300 watts.
edit: *** Sorry, I missed the part when you measured the solar light level *** (1100)
The panels were still over 25°C warm so that's limiting the power as well.
Very true... Panels are about 70% efficient.
i just ordered the same solar panel tester 69usd on ebay
I love that you do the tests! I really like the crazy tests like one full 280Ah battery 🔋 and an empty one! Very entertaining and verifiable legitimate information. Some tests of multiple BMS situations on one battery pack as in Active Equalizing Balancer and Passive BMS and multiple 5 amp Active Equalizing Balancer and a Passive BMS. Active Equalizing Balancer that only Equalization balance between adjacent batteries and those that claim Equalization balance all batteries at the same time. Then using both and a Passive BMS. Maybe even pushing it to the point of letting the magic smoke out and a little drama of a fire extinguisher 🧯. Hey, I'll watch 😆 🤣 😂 😹
Hahaha, don't get too excited!
@@OffGridGarageAustralia it's always easier to watch! Thanks for all the adventure of examination and tedious time consuming work.
@@OffGridGarageAustralia BTW I have a 20,000 watt hour lead acid 48v system and working on two 48v 16s 310AH CATL Lifepo4 3.2V banks right now. Top balancing as I type this. Thanks again for all the enthusiasm and encouragement.
@@xr680r Thank you 😉
I have same inverter and I just installed I vage 400w solar panels it’s all connect it’s showing a tiring ok on display the voltage of panels the loads of the house but the inverter it’s not producing no power and it’s completely full sun on the panels and I did set the inverter to 250w or I did put off the limit but still no power produced by inverter any idea??
You mixing solar panel mono & poly in series why ?.
I'd love to get one of these or something like it to Sweden 🇸🇪
Hi there, how is that inverter doing by now?
Also at roughly 50v these inverters start lowering their output. That’s another reason why a 48v battery shouldn’t be used. Also you really want the voc of the connected array to be roughly 80 so when the mppt draws the voltage down you stay safely away from the bottom voltage range
Agreed I would have used the lower voltage inverter and stayed in the upper part of the band but I only use battery so solar panels would take more connections with lower voltage.
From the previous test, I could see it outputting 1.6kW at 49V with no problem.
This is only for short time. Below 52 volts it cannot output this for much time.
@Off-Grid Garage hi, I have 2 (maybe stupid) questions. After I made my research for this grid tie converter I was not able to find what happens in case of a grid brownout.
I'm thinking about getting the small 1000 for 24v battery pack, the datasheet says it can do 22 to 60v DC but in () next to it "starting voltage 26v" dose this even work with 24v pack using 3.2v cells?
And most important is this thing still working in a brownout situation?
I live in the Philippines and we have common brownouts sometime lasting for hours.
Hab ich den Dialekt richtig gedeutet und hätte auch auf Deutsch fragen können?
I wish you could manual input the ideal power point of panels into the inverter settings...but of course hot panels do screw things up...do same test in winter... 🥶
Which solar power meter are you using?
Can you connect 2kW panels? How much can you connect?
the consumption was more expensive for me rather! that I have badly connected
do you know where the ct sensor goes
I have 220 in the neutral, ground or positive phase?
I have this model
SUN 1000W Solar Grid Tie Inverter with Limiter Sensor Wi-Fi DC 22-65V 45-90V AC
When measuring panel output, connect a 1 ohm 500 watt resistor across the output of the panel. Square the voltage, and that is the wattage output
but that is not the MPPT condition
Can you just connect the GTIL2 to any outlet or do you have to connect it to a fuse panel in your breaker box ?
It is designed to be plugged into an outlet. The outlet is fused in your sub panel. But please check with your local regulations.
With an 80W load, why is it pulling anything from the grid? I would think you'd still be able to put at least 100W back into the grid no?
👍👍
Nice does this inverter have the option to run from batteries charged, but also a option where it can control discharge of batteries to a percentage say not more the 50% so batteries do no get fully drained. Thanks
Yes
I am not familiar with your solar tester meter (the orange and white one). Where do I get that? I have done it all manually with volts and amps and then calculating watts in my head. Your meter makes it so easy.
All links are in the description and you can find it here on my website: off-grid-garage.com/measurement-tools-and-analisers/
What does this solar inverter do when it experiences a power outage on the mains? Does it back feed power to the mains or does it shut off? Sorry if this is something you've covered already.
it has, as all inverters, Anti Islanding.
Wait, the instructions say that the GTIL2 hooks up to a PV, so I was going to ask if any special requirements working with batteries. Your video says you are just testing it with PV now implying you were using batteries before. So you have no problem w/48V LiFePO4 batteries with the 45-90V version?
i was just wondering could these be used along with say a battery powered inverter to produce the signwave and then these give the extra power that needed or if they will damage the battery powered inverter
I was wondering the same thing if it can reduce the load of the battery off grid inverter I worry tho at times it slightly feeds back into the grid im not sure what effect that would have on a system like that
I know it says you need 45v but i noticed when you where uping the volts you got to 34.2v and the red message went away, so dose that mean it can work at just 34v ?
It may work at these voltage with very small loads. In the settings you can specify when to turn on and off the inverter.
it is possible to connect a storage battery to this inverter adding a charge regulator?
yes
Perhaps dirty panels with cable volts drop accounts for difference.
Ice Cold S.P.A.T.s FTW! :)
🍻
What is the maximum Voc and Isc from solar can inverter handle?
Have a look on my website, there are links to these inverters with all the specs.
"uncalibrated SPAT" .. priceless :-)
🤷♂️ that's what it was 😁😊
So how many hours or months experience do you have with those inverters? Do you recomend them? There are some fail videos about those devices. Can I avoid destruction by limiting the power to 75% of max or something like that?
I have seen a lot of videos about those and people seem to be generally happy. They limit power output automatically as per settings.
I have a standard one way mains meter in the united States. Will my meter see the power from this inverter and charge me for it? I have heard some in the states say that is the case.
If you use the clamp sensor correctly, the inverter will not export any power.
@@OffGridGarageAustralia that's correct, but, I have heard my U.S. meter from my power company still sees it and charges me? Whatever it creates? I don't see how though. My meter should never see the inverter at all.
I have had some people tell me if your inverter makes 400 watts and you used all of it, no export, my power meter outside will still see it and charge me anyway. Makes no sense to me. How could it see it if it never exported.
I want to make sure that's right to. I'd like to buy 3 of these and run them at 1/3 capacity.
@@kevinroberts781 that is wrong what people tell you. If you have a load of 400W in your home, the inverter will produce 396W of it and you will still pay for the remaining 4W coming through your meter.
Have a look on YT here, you will find heaps of videos where it is explained and shown as well.
Could you do a test with battery and solar? I do not understand how a battery connected to the DC inputs would deal with MPPT as the inverter tries to adjust to a battery and not solar. Do you have to put a disconnect between the inverter and battery and then use a charge controller to charge the battery and then switch off the charge controller and switch on the connection from the inverter to the battery?? I'm confused how it can work on a battery and have battery charging. I completely understand how you could just replace the solar input with battery input. It is the charging of the battery that I don't get.
It works, many videos on TH-cam showing this. The test I did in the previous video was with a power supply. The MPPT does not track the power point and stays constant. Same for a battery input.
please what resistors are these two for the smooth charging of the capacitors how many ohms and how many watts are each thank you very much
i have the same question - i ordered a 30 ohm one should be ok
@@erhardschreck2192 thank you very much for the information
Do you have more information on buying batteries from Alibaba? It's it safe paying with western union?
I did buy from Alibaba before about 15 years ago but I'm not sure now..
Thanks, Jens... 😎
Hello, can this inverter charge the batteries from solar and from the grid ? Thanks
It's not a charger. It's a grid tied inverter which can run from solar, a battery or both.
Shade? Schade!
But that's llife with solar panels...
30°C? Not bad for winter... But i would be happy, if it was that "cold" for few days at the moment...
Enjoy calibrating SPATs ;-)
And then go on with the shelve ;-)
Hi Andy, i had the same problems with my solar system, can u please give the mppt a chance when u are using 2 off the same solarmodules? Shading is really tricky on solarmodules, but if u have 2 or more in a string of the same modules, the mppt can find the global spot, to work.
I bought 2 new (120 cell before, it was 60 cell modules) and i have arround 140% until 200% more power in the morning, when one is shaded.
Best wishes from Germany/Bremen but please look for a local dealer wich has another german beer for u :D .
Have a nice day/night.
Thank you. The solar panels are all used. New modern split-cell panels have a better efficiency with shading. Maybe in the future...
Your panel tilt was already more then 45 degrees, its not just how directly the sun hits the panels, it is as well how much atmosphere the rays have to go through. A deep standing sun can never produce the same amount of power the the sun at noon. That's why there is as well a seasonal effect. Winter-sun now, right?
Yeah, still winter down here. But soon...
Solar Noon and "noon" are not the same things.
Would love to see 10aH 48V pack of supercapacitors in parallel with that
Hiya, you just need to be careful with the input voltages. The 1000 and 2000 have different input voltages if you are using batteries.
2000 is 45 to 90v dc
I run my 1000 with 2 Tesla modules because I’m not in during the day and this allows me to use the solar at night!
I like the idea of using 2 together.
For daytime I tried a mastervolt 500w grid tied inverter and it covers the fridges and tv.
(Interestingly the ct clamp display on the sun shows the wats in / out of the house.)
Will have to save up for the 2000 watt one.
Take care all.
You would lose mppt capability I think.
You need to set up some water for the ponies playing and cool off your solar panels too
Danke für die Videos über diesen Inverter! Ich raffe das irgendwann noch mit den Limitern... es geht nur an 2 von 3 phasen im haus - richtig? Das mit dem Öttinger war ein Knaller 😁
der SUN arbeitet nur auf einer Phase, ergo: je Phase ein SUN. Im Fall von Andy sind das halt nur 2 weil, aus welchen Grund auch immer nur 2 Phasen ins Haus verlegt wurden.
Das mit dem Limiter ist relative simple: er misst den Strom der durch das jeweilige Phasenkabel läuft und der verbundene SUN-GTIL Inverter versucht diesen Wert Richtung Null zu bringen.
@@alexandergunda8916 Danke erstmal. Meine Hauptfrage ist: mein haus nutzt alle drei phasen in den verschiedenen räumen. Kann ich mit drei Sun Wechselrichtern alles abdecken? Ich meine irgendwo gehört zu haben, dass sie sich dann gegenseitig stören...?
@@andylambertz4364 würde ich nicht meinen, es sind ja unterschiedliche Kreise, aber falls zB. der Verbrauch auf einer Phase die Leistung des entsprechenden SUNs übersteigt kann dieser (der restliche Verbrauch) nicht von den anderen Phasen kompensiert werden. Sie arbeiten halt unabhängig von einander.
Falls eine Abdeckung aller Phasen gewünscht wird sollte vielleicht auch über einen 3Phasen Wechselrichter nachgedacht werden.
Ich persönlich verwende nur einen SUN-1000 in Zusammenhang mit der AC-gekoppelten DIY-Batterie die Steuerung wird aber nicht, wie hier von Andy gezeigt, mittels der "Strommesszange" realisiert sondern mittels einem variablen Widerstands (siehe "Der Kanal"); die PV ist mit einem Fronius Symo WR gekoppelt.
@@alexandergunda8916 Vielen Dank, werd mal auf der Kanal vorbeischaun und nochmal überlegen ob ich wirklich alle 3 phasen abdecken muss.
Das geht auf jedem Fall. Da kannst Du Video drueber finden. 3 Wechselrichter, einen auf jede Phase und du hast alles abgedeckt.
you tested panels at voc. when the mppt is on its vmp. so lower voltage with a load on.
I tested both in the video 😉
@@OffGridGarageAustralia must have missed that. woops.
I have 2 inverter 2000w angering error mm
can the inverter use batteries and solar at the same time?
yes
No wonder why they say the solar panels are only supposed to last 25-30 no one takes care of them no one really cleans them no one really takes care of the wiring who replaces the bad wiring. I suppose that's why I'm a thirty-five-year-old so can I still give me the exact same watts it did when I put them up or is it I just kept it looking brand new for all its entire life as I receive power from the solar panels to run my house.
Das gute alte Öttimger
the smallest Impp of one of the pannel is bringing the other down ...
Standby power consumption? Power conversion efficiency%? Max ac output?Thumbs up and subscribed?
Thank you! I've shown this in the previous video.
Measure dc volts and amps at inverter connection from solar while connected to grid with load.
The inverters shows the voltage on the display and the amps will be the same, regardless where you would measure.
Could be losses in the wire from the solar to the inverter.
It's a 2.5mm cable and the current was only 6m. There are some losses, but not much.
SPAT required .....
Have calibrated it now, working much better 🍺
Your documentation is lacking… I can’t find where you list a part number and supplier link for a SPAT or even a 6-pack of SPATs!
I haven't got a sponsor yet! 🍺
You never get max power from panels. Real world, Lucky to get 75% of what the max the panels say they can give. Nothings wrong with the inverters mppt
You can get full rated power and more. done it many times with quality real TUV rated panels. this myth comes from the large amount of cheap fake rated panels on the market. people think its normal to never see above 70-80% output but its not.
Depends on the solar irradiance.
Clear skies at noon should give 100%, but high level clouds or haze can bring that way down.
I'm getting full power from my panels under certain conditions. Cold wind and the sun comes out behind thick clouds. 110% I've measured for 20-30s. Once the panels heat up again, the power output drops though.
I saw someone's legs and now I wanna know whom
Series wirring of panels or batteries increases voltage not amperage.
