Just watched it again. Excellent explanations!!
Great explanation! This should be helpful for many people!
Great explanation! thanks
Perfect, keep up the good work.
This is great ..... well gone👍
The limiter explanation is perfect and will be useful in the future.
So if I have 1650Watt peak panels on a 1KW model inverter, I can limit the peak Watts to say 850Watts to keep the unit cooler and extend life expectancy. May upgrade to a 2KW model inverter in the future or a second 1KW 🤔👍
I have a question: As long as the voltage stays below the maximum (DC), can I have lots more than 1000Watts of panels? I would like to do that so I get more power on cloudy days.
Perfect video, thank you
Nice video..hope you can explain and show how that inverter being set up and how it connected to the grid and to the batteries..tnx! More power..
it's already there: th-cam.com/video/gek4x4sh9MA/w-d-xo.html
(you don't need 2 sensors if you have only Phase and Neutral)
@@SolarEngineering tnx! Im planing to purchase that kind of inverter..tnx again.
Hi i need help. I have 2 1000w inverters bought months apart. We had a storm and now neither is working. I'm still getting power from the panels, but neither inverter is working. I have 1000 each in panels putting about 750-820 watts each in full sun. I could see if one stopped, but both makes me think something happened during the storm. No close lightning was observed, we were home. Is there a reset or any thing you or viewers could suggest. One is about 1 year old and the other is 7 months. Both have worked flawlessly since hook up. Thanks
Hi, sorry to hear that.. I don't know if there reset functionality, I can only recommend to disconnect panels and AC from inverter and let it seat for about 30 minutes, then connect AC back and PV panels.
My 2k 45-90 arrives tomorrow. Still in the process of getting mounting gear for panels. Is it safe to power up the gtil without the panels attached just to look around the menus and things?
sure, it will work.
I have a question sir, do you advice to keep the LCD always on? I’m afraid later it might have some problems.
mine is on from April (5 month) so far so good, didn't see any problems
Hello I have a question about the 2KW watt inverter that you connect the limiter sensor in series when connecting the limiter sensor to the grid which direction do you turn the arrow in?
Hi, I did update to cable. Now sensors connected in parallel.
The sensor on one leg is reversed (one pointing to panel, second out of panel).
Take a look at this video: th-cam.com/video/PcIfI7jypB4/w-d-xo.html
Let me know if you have any other questions.
Thank you. Very easy to understand the way you did it. Also, you didn't go too fast. I have a question: When we set the limit for the inverter's power out, that is not the limit provided by the Internal limiter (Clamp) Correct? I am trying to make sure that once I have my Clamp on one leg of my power from the grid, my inverter will not back feed the grid. (In my case the grid power company would fine ($$$$$) me or shut off my power). I have 900Watts Maximum of panels (not batteries) and plan to let my inverter use the full 900Watts if needed, BUT, I don't want it to ever supply more than demand and back feed the grid. Will it do that?
To prevent backfeeding you'll need to setup CT sensor, sensor will let inverter know how many watts it needs to produce.
Limitation in settings (that I'm explaining on 4:09) is to limit TOTAL inveter power production, here are few examples (assuming that you installed CT sensor):
Example 1. Panels producing 900W, house consuming 600W, limited power mode is OFF:
Inverter will produce 600W of power to cover house needs. Rest 300W of power will be unused.
Example 2. Panels producing 700W, house consuming 1000W, limited power mode is OFF:
Inverter will produce 700W of power to cover house needs, rest of 300W will be taken from the grid.
Example 3. Panels producing 900W, house consuming 900W, limited power mode is ON and set to 200W:
Inverter will produce 200W, the rest of 700W will be taken from the grid.
Please let me know if it's clear now, and thanks for the feedback.
@@SolarEngineering Thank you. Extremely helpful. I understand now due to your very clear explanation and examples. Do you have a Wifi tutorial for this inverter? I now have two but not set up. I am still testing using batteries. Do I set one inverter to "01" and the other to "02" for the WiFi? They each have a WiFi dongle.
@@benkanobe7500 Hi Ben, I did setup WiFi only to one inverter.
here is video: th-cam.com/video/ocUuXj01UhU/w-d-xo.html
@@SolarEngineering Thank you! I watched it twice. I just need to know if I need to change the "01" setting on the second inverter to "02" so I can independently WiFi monitor each GTIL contribution to off-setting my loads.
@@benkanobe7500 I'm not sure about that, I'd start with 01/01 on 2 inverters and if it doesn't work then change 02 on 2nd inverter.
Looking forward to buy 2000w model to use it with 330watt 37.2Vmp 46Voc panels. Am I right in thinking that I can configure panels in 3 series of 2 panels each or it is too much?
90v is Max voltage for inverter. So 2 panels in series will work.
Can you connect 2kW panels? How much can you connect?
Hello here from Canada! great video as always! I ordered a 1000w model for L1 and another 1000w model for L2. I have a 40amp breaker panel in my detached garage that is tied to my mainbreaker panel in my house. Can the current sensor be installed in my garage panel? Thank you.
Hi, yes. CT could be installed on wires coming from main panel to subpanel.
Okay but its best to tie it on my main source at my main panel. Correct?
@@fkdeazevedo if you want to offset usage from the main and sub-panel, then CT needs t be installed in the main. If you have loads only in the sub-panel, then CT in the subpanel or main.
Hi please explain how maximum panels we can connect to the tie inverter
Hi.
Can you connect 59v battery instead of solar panels?
Regards.
yes, that what I have. (16cells LiFePo4)
th-cam.com/video/gek4x4sh9MA/w-d-xo.html
Great video why do you use batteries instead directly connecting to solar panel
I cannot backfeed grid. And my electricity usage is less than solar panels producing. So storing energy in batteries and using later in evening.
Also if grid power will be off, I can connect offgrid inverter and power critical loads.
Will it also feed the house with electricity if the external grid goes blackout?
it will shut down to prevent feeding back the Grid.
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 .
Hi, is this inverter work when the grid is down? As long as you have battery? Thanks
nope, it's shutting down when grid is not available.
How you can put 2000 W solar panel if you are limited at 90v?
330W 6 panels.
2 panels in series 3 in parallel
Dear Sir .I have bought 3 on grid inverters with limiter.2KW each .Each one has a white sensor [ a coil ] that goes to the main cable of my house electric panel of GRID. Question. Can i connect together these 3 inverters and all of them to be able to push to the house 6KW instead of 2 Kw ?? DO i need to place one sensor in the main cable of the board and where shall i connect this sensor in series in the top of the 3 inverters???? Question some other blue sensors they have where are being connected to the 2 cables + and - from Panes voltage?? and where do i connect this sensors then .in the three inverters???? Being thankful to you for your consideration.Thank you
Hi there, too many questions in one :)
Let me first ask you few questions:
1. What kind of electrical system do you have? (Split phase system like in US/Canada, or just single phase like most parts of Europe and Asia)?
2. Do you want to limit inverters' output, or do you want them to supply full power to the GRID?
My 22V 1000W model does not show the house wattage. :(
it might happen if the limiter is not attached.
@@SolarEngineering Yeah, sorry, I figured that out!
Did you get from it more then 1700w of power?
1750w is a max I saw on inverter. Also I noticed that inverter can output 1.7kw only when battery is fully charged, as soon as voltage drops, output decreased (even when battery 50%+ SOC)
@@SolarEngineering Yep same here, 1700-1650 max, i wonder is it have some current limit and on 70v could show 2000 or it is real maximum power...
Anyone know how to factory reset these?
Как удалить ( очистить ) статистику общей выработки кВт на гриде ?
в меню такой опции нет.
@@SolarEngineering а мне альтернативщики написали другое .
@@Vasya_V тогда не понимаю вопрос, если они написали что можно сбросить, то там и должен быть ответ как именно это сделать.
В меню опции сброса счетчика нет, возможно есть сервисное меню которое надо каким-то образом активировать.
Any one can help with message grid error?
check Facebook group "GTIL Group"
I know some people got support from this group.
Please tell me how to repair
what is the issue with inverter?
Find on facebook Mr. Rogel Naval . Electrician Eng . He is the one develop that unit .
Hello, i got problem with my sun gtil 2000 (45-90) version 5.1. suddenly it change to (10-30) version. And my lcd shows text input voltage to high. I dont know why its happen this morning. Could you please help to resetting the inverter?
How did it end?
Same here, looking for way to reset it as well
