2kW Grid Tie inverter with 2 CT sensors. Part 3 of 3. For US split-phase system. 

I wouldn't have thought that this would work given that the two phases are out of phase with each other. But hey, it worked so well done :) :) :) I will try this on my three phase 230v.

Awesome! Thanks for sharing. Looking forward to seeing more of your videos. I would like to see more about your battery bank.

Excellent. You showed me that I can extend perhaps the clamp cable... several feet ...since my battery bank and the breaker panel are about 30 ft apart. Since the output is current...maybe it will have little effect at the inverter input. Therefore, I don't need to buy the extender limiter. I read somewhere .that if you have the clamp connected at the panel ..you better have at least a resistor to dissipate the current at the end or have it already connected to the inverter. Good Job!!!

This is good especially the limiting factor of ba k feeding to the grid.

I would like to see like a seperate leg test for each side

I really appreciate this effort. And, your hard work to master the English language. I have a sincere input: Maybe find an automated translator you could feed your audio through to make it easier for North Americans to understand. You did a great job on this and translated very useful information. Thank you.

Thanks for your time and effort. Great video with practical information. Do you know if this set up will work with the 1000 w version for 240vac?.

Great Information. Well Done. I am considering buying a 1.5kw system with this grid tie inverter. my meter has a round dial and looks like an older model. Pretty sure I don't need to do this hack. But great that you figured it out. Helping the common man is a great thing you have done here. Is there a way to send the power to your battery automatically instead of it going to the grid?

Thank you for the video. Does the inverter calculate wattage based on voltage from the sensors? I'm just curios as to why you connected them in series and not parallel, I thought these sensors measure the current.

very good video . thank you for sharing . do you have a video showing how you have the output from the inverter to your home grid is connected , is the AC cable connected directly to an outlet or main panel ?

Thanks!

The video is very good, I just didn't quite understand the reason for installing the two sensors and which network cables they are connected to, I'm watching the video with a translator, so there is a little doubt, if you answer I'm very grateful, thank you .

ok perfect what a genius are you one question then go from the energy meter I have current 220v to 110 But then I will connect the ct to ground or negative phase or positive phase in which sir?

Great video !!! One question. What is the maximum input current for the limiter input? Do you have a data sheet? Could it be that you destroy you input if the input current goes higher than 50mA. I think the current of both sensors is added together so there is the danger that in the worst case the input current is higher than the allowed input current.

Should there be any issue with using two of these 2000 watt inverters? Keep the great videos coming!

Hello! Do you think this inverter can work with 4 x 255W panels and no batteries? The panels are too big for the 1k inverter (VOC 38.7, VMP 30.6, 8.32A), so I think the 2k gives good room for expansion. The only configuration I can think of is two strings of 2, joined in parallel so 77.4V, 61.2V and 16.64A. It should be okay for the 45V-90V input but there is no DC amp input listed. Will 17.7A be okay? Do you think the dryer plug or direct into a two pole breaker is better, and for safety do you think the inverter should have DC and AC protection e.g breakers and shut off switches either side? Sorry for so many questions.

what about running each split phase leg through the one sensor, one in the opposite direction?

你好，請問這個2個CT傳感器的型號是？

Great video as always. My panel is located in the exterior of my house. My set is in my garage which is 50ft away. Do you think the CT clamps will be able to ready line 1&2 because of the distance ? Thanks

refers to the sensor where it should be connected It has to be connector after the electrical box or where

How is the inverter holding up? Did you reduce the output to extend the life of the inverter?

THANKS so much for your response. Not sure how to read the display and what its telling me. These were some of the readings I'm getting. I have 6 300 watt panels. 521.1w (solar) 1600 w (Small # under 240 volt) 1064.4w (solar) 1597 w (Small # under 240 volt) 1192.5w (solar) 1594 w (Small # under 240 volt) 1324.8w (solar)1602w (Small # under 240 volt) Does it look like I have this setup correctly?

What batterys did u use? I got 8 12V 35AH deep cycle seal Lead acid ones for a 48V system. (on a tight budget).

Great Video! Can this be done with the 1000W grid tie inverter? I'm going to try to set up the 1000W inverter here in Los Angeles...hopefully the power company doesn't come knocking on my door.

Wondering if the 2kW inverter has the option to use it on a single leg (120V) and use a smaller battery bank (36V) I know it says DC input of minimum 45V but didn't know if it was possible if only using it for a smaller load. I know I can buy the 1kW version and it will do this fine, but I would like to leave room to build onto my battery bank. Love the videos, you have a lot of great information. One of the other things I was wondering on these units, can you have them put them on schedule? I have great off peak pricing and am looking for a way to use it to my advantage.

What is the best configuration if I already bought two 1000 W with limiters, my setup is one for each leg.

Hi, I am about to buy the same inverter, but I have to place it far away from the electric panel. I was thinking about running a long 2-wire cable to extend the sensor original cable. Do you know how long the sensor cable could be without affecting the data readings?

My SUN-2000W GTIL2 will not save settings after correct operations. Any ideas as to how to factory reset, or correct the problem. THANK YOU. Cliff

You wouldn't happen to know the specifications on the Emporia energy Vue Gen 2 CT censors would you... I'm pretty sure I have the same unit you do there's the 2 100 amp main CT centers and then there are smaller 50 amp ct's for circuits but none of the CT sensors have specifications on them... I'm kind of wondering if the burden resistor is located in the CT sensor or in the actual vue box itself?

At 7:50 it appears you have set up your GTI as if it were connected to Solar Panels and not battery. In this mode it will use MPPT, if you use either of the other selectable limit modes and input a setting, it is my understanding from Mars Rock that MPPT is then disabled. I need help understanding how you set up the Menu for using batteries and a what I think is a stand alone MPPT Charge Controller (Outback/Midnite). Thank you as I know I ask/asked lots of questions and you have moved way beyond these little GTIs and are using SolArk now. The chart for my house looks similar. My base consumption is 230Watts so that is what I get from around 10PM until around 8:00AM when sun hits my panels. After 8:00AM until 6:00PM my meter reads between 0.000KW and 0.032Watts all day long. I want to have my batteries run at night and need to understand how you set up the GTIL Menu to run batteries at night and Solar during the day. Thank you! Mine works perfect during the day and I don't need to adjust anything (I have an excellent property for solar so my ground based panels are setup for "sunrise", "mid day", and "sunset").

After 6 mnths mine has "grid error" message and no output. Company not helpful. Do you have a site or number for help? Thanks for the excellent video and for responding/helping people.....

Hello, I want to compensate 3 Phase(Legs) Grid here in germany with 1 inverter. Are this working with 3 CT senors parallel or serial?

I have 14 battery modules. Each one has 12 lithium ion battery cells. The nominal voltage for each module is 3.7 * 12 = 44.4 , the charging voltage is 50.4v. The low discharging protection voltage is 36v. I want to charge the battery in the night and use the battery during the day for time-of-day purpose. I like what I am seeing here. If I use a limiter so I would like to have 2000w model which does not support input voltage as low as 36v. Is there a setting to adjust the input voltage? Thanks.

A question please: Can I use these clamps via wifi with a transceiver?. Thank,s.

I just installed this unit (2000 watt model) It looks like you have both sensors arrows are pointing to the right. shouldn't 1 point left???

so for a 240v us system wire the sensor in parallel or in series.

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

So you got a 240v inverter connected to the dryer connector? Hmmm that is interesting...

How has this inverter held up? Still functioning as it should?

So If I get a 110v GTIL with one CT, I will be feeding only one leg and other leg will no be feed, and it will no backfeed... becuase is 110v and is only serving on hot from meter (provider) ---- to feed whole household... a GTIL on each leg... conected to a outled for the corresponging Hot wire.... ?

hello, would this work with 3 CT sensors? I have a 3 phase electrical system. Thanks

What charges your batteries.do you have solar panels?

hello, if we have one phase, how we connect 2 limiter sensors ?on the same phase will work? i wait 2 grid tie inverters so i ask your help please

what's the difference between 2 ct sensors clamp on 2 phases and 1 ct sensor clamp on 2 phases (2 lines at same time ) . Are they same ?

Hello, if connect two-phase 220v, will I have an injection in both phases? Or only in the phase that has a current sensor.

Can u verify the amount of power u are using matches what your inverter screen says the grid is supplying? If u are backfeeding it will show as a positive reading on your electric company meter and u will be charged for it. Can u verify with your emporia monitor?

Will this run without limiter. I have net metered and want power to run back to grid

What size wire is used in these wires.

I have the same unit (SUN-GTIL2 2kW), but mine will shut it self off after running for few hours at around 600W outputs. The LCD turns black and I heard the AC plug has sparking sound. After turning everything off for a few minutes and turn on again, it will boots normally and start output power. However, I can see the temperature shown on the LCD is around 50C. May I know at what temperature will the fan turns on? From your video, I can hear your fan is spinning constantly (8:15) even at 400W. The fan on my unit doesnt spin at all... Initially i tot because of the low output, but now it seems like the unit is shutting down due to overheating...

will you do another video of grid tie and does it still work after 3 years

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 .

I have the same bug on starting the inverter, starts with 1450w. When set limiter and battery type I had constant 125w and no reaction on high grid consumption. How did you fix the inverter bugs?

Ciao sono italiano mi potresti scrivere qui nel commento come collegare il limitatore di corrente e come collegarlo grazie mille

Can i use this inverter without connecting the limiter or it will not feed power into the grid at all?

Is this set up still working for you? I see that the video was made in 2020 is why I'm asking.

For the US 220V, what did you connect the ground to? You L1, L2 & N, where does ground go?

With two ct clamp sensors in series to the limiter how does the inverter know to send for example 2 amps to L1 and 5 amps to L2?

Resistor at min 05:58 - what is the Ohm = 800 ?

Hello, does it work also on Solis on-grid 4G mini single phase inverter? Our utility is split phase 240v.

Can I use 120 volt

Will this plug in 110v in your plug?

Your Amazon link for the inverter has gone down. Any chance you can link to the model you use? I am guessing its a likely a lot cheaper to order from Aliexpress or something anyways.. So throw up a patreon link so I can send you some beer money.

Hey can you send me the RU-vid video again about the limiter sensor

I just got mine install today, the meter go backwards very super slow the number stay the same when no big load. Is this normal? Am i doing it right?

The inverter is design for 1 leg. USA has two legs combined at 240v. 120v per leg. The CT is design for 1 leg. If you split the CT's and run the inveter at 240vac split phase how does it know how to distribute an unbalanced load by doing this since there is only 1 input for the CT. If your fridge on leg 1 is drawing 200 watts at 120v and your washer on leg 2 is drawing 500 watts seems the inverter will put out 700 watts. Having that said. I assume each leg from the inverter is pushing back 350w per leg meaning. The fridge is getting 150 watts more witch goes back on the grid. The fridge is 150 watts short. As again seems to me you will be back feeding the grid with 150w. Can the inverter manipulate each leg vs each legs power draw. If not this idea is no good for USA split phase system. Seems the joining of the two CT's is adding up the watts for a 240v application. Again the concern is how it dustrbutes per leg. Thoughts?

If L1 is requesting 100w and L2 Requesting 500w, does the Inverter will know which one needs what?

How does the inverter know which leg the power is coming from

Prise koto

Your explanation is CONFUSING, How can your inverter supply ANYTHING at night with NO sun? Do you have batteries on it? You don't mention having batteries at all.

how is the operation of the 110v equipment? your inverter is 220v, in that case you put two sensors the grid will inject current into the network when you have 110v equipment? in my resistance I have 110v and 220v equipment. I used Google Translator
