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!
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 🍻🍻
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.
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!
Great video. thanks! What happens in a situation when you produce more power then consumed (without the limiter) and don't have solar tariff ? Does it causes any issues with the meter? upsets the electricity provider?
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 ?
@@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!🤦♂️
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??
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.
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
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)
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... 🥶
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
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.
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.
@@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.
Maybe they notice you suddenly started using "4kwh" less and come and investigate what's going on, but that's not technically the meter KNOWING you are using solar generated power in your house. Gotta protect that revenue stream!
@@CollinBaillie I guess if it doesn't spin the meter they will never see it. What I have always heard is that it will spin the meter even if it's not sent to the grid. That doesn't make sense tho. Whoever told me that didn't know either.
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?
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.
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?
That sounds reasonable. Be aware that in cooler days, or when the inverter's MPPT controller circuitry is first starting, that open circuit voltage may be higher and you would risk damaging the inverter with 2 in series. Usually you want the solar string max (open circuit) voltage to be Inverter Max Vin ÷ 1.21. Around 74.5v open circuit total for a string, on a 90v max Vin inverter. So, you should be ok, or change out the panels for those with say 35-38v Voc.
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.
This inverter doesn't charge a battery. You would need to go: Solar -> MPPT -> Battery -> Inverter No need for disconnects or anything else. If the MPPT is producing DC Power, it will charge the batteries with anything the inverter isn't using.
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
To use this with solar and batteries your setup would be: Solar Panels -> MPPT Charge Controller -> Batteries -> Inverter Including all of the necessary isolation and safety bits like fuses, circuit breakers etc.
@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?
If the grid disappears, these will stop working. A 24v (nominal) battery is around 29v fully charged, so it should definitely start up if the battery is fully charged. If you run this from a battery, you will need an MPPT charge controller to charge the battery from solar. Of course you would want to produce more from solar/MPPT than the inverter uses, so that the batteries charge during sunlight hours and then they power the inverter through the night, until they are discharged and just grid power is used then.
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?
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.
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.
That was the Elejoy WS400a. They have newer models now: Elejoy EL400B Elejoy EY800w Elejoy EY1600w Andy has links to all of his equipment on his website, which is linked in the description of the video.
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.
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
If you treat the off-grid (grid-forming) inverter as your mains grid, and put the CT Clamp around its output, it should work just the way it does with a real mains grid.
If it's a 2kw inverter, you should be able to connect 2kw of panels, so long as you don't exceed the input voltage. Say you have the 24v-60v version (Which I think Andy demonstrates here) you would probably use strings of up to 50v which allows for low temperature voltage highs during cooler months (Solar string Voc Total = Inverter Max Vin ÷ 1.21) For 2000w, that would be around 30A at 60v, so 50v per string, with a total of 30a would be safe. If you have 6a per string, you could have 5 strings. Maybe you could over panel by another string to allow for better results during low light. 10-12 panels of 200w, 2 per sting, 5-6 strings. Maybe only 5 strings if using 220-250w panels.
That's the functionality of the limiter. It makes sure that it produces less than the grid load of your house. You will always draw a few watts from the grid, guaranteeing that the inverter never feeds back into the grid. Also, the inverter is powered from the grid, not from the power it generates.
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?
Andy's previous video was testing with a benchtop DC supply, essentially a battery, for the sake of the test. It should work perfectly with a 48v Lifepo4 battery, but Andy has thr 22-60v version. 45v-90v should also work ok with 48v battery (45v would be 2.8v per cell)
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 😆 🤣 😂 😹
@@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.
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?
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.
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.
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.
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... 😎
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.
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 ;-)
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.
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.
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.

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.
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.
It shuts off. It will only work if the grid can be sensed.
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.
That was the Elejoy WS400a. They have newer models now:
Elejoy EL400B
Elejoy EY800w
Elejoy EY1600w
Andy has links to all of his equipment on his website, which is linked in the description of the video.
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.
Is the plug provided suitable for Australia or does it need to be modified? Thanks
I believe it has a (IEC 60320) C13 style plug. The infamous "kettle cord". The same you use to plug into a computer
I love the sonoff products
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
If you treat the off-grid (grid-forming) inverter as your mains grid, and put the CT Clamp around its output, it should work just the way it does with a real mains grid.
i just ordered the same solar panel tester 69usd on ebay
Yes 👍 🔌 🔋 ⚡
can the inverter use batteries and solar at the same time?
yes
Great machine. 🇬🇧
Can you connect 2kW panels? How much can you connect?
If it's a 2kw inverter, you should be able to connect 2kw of panels, so long as you don't exceed the input voltage.
Say you have the 24v-60v version (Which I think Andy demonstrates here) you would probably use strings of up to 50v which allows for low temperature voltage highs during cooler months (Solar string Voc Total = Inverter Max Vin ÷ 1.21)
For 2000w, that would be around 30A at 60v, so 50v per string, with a total of 30a would be safe. If you have 6a per string, you could have 5 strings. Maybe you could over panel by another string to allow for better results during low light. 10-12 panels of 200w, 2 per sting, 5-6 strings. Maybe only 5 strings if using 220-250w panels.
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?
That's the functionality of the limiter. It makes sure that it produces less than the grid load of your house. You will always draw a few watts from the grid, guaranteeing that the inverter never feeds back into the grid.
Also, the inverter is powered from the grid, not from the power it generates.
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?
Andy's previous video was testing with a benchtop DC supply, essentially a battery, for the sake of the test. It should work perfectly with a 48v Lifepo4 battery, but Andy has thr 22-60v version. 45v-90v should also work ok with 48v battery (45v would be 2.8v per cell)
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
Beau test ! Merci
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 😉
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.
Which solar power meter are you using?
ELEJOY WS400A
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.
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.
Ice Cold S.P.A.T.s FTW! :)

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.
I'd love to get one of these or something like it to Sweden 🇸🇪
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...
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.
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... 😎
"uncalibrated SPAT" .. priceless :-)
🤷♂️ that's what it was 😁😊
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.
I have 2 inverter 2000w angering error mm
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 ;-)
You need to set up some water for the ponies playing and cool off your solar panels too
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.
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! 🍺
👍👍
SPAT required .....
Have calibrated it now, working much better 🍺
Das gute alte Öttimger
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
Thank you man! 👍🥸
