I have watched all your KZbin regarding this set up and your final set up before moving up to Solark. I completely understand your excellent demonstrations. It is the next one where I get confused. Here is why:

[@peterlindstrom8865]

Well explained from someone who is born in a 3 phase 240V country 😉

[@motoprophet3981]

Great series on this limiter! I appreciate you taking time do do it. Thank you very much!

[@JesudomEnergyGroup]

Thanks ,it’s very helpful for one of customers in USA.

[@beyondfossil]

I was thinking that limiter/throttle feature could

[@NewsBroadcasting]

cool video, we have same unit it stopped working after 2 years , we check the DC fuses they are ok,. anyway to fix it? do we have to desolder all teh MOSFETs to check them ?

[@jimthvac100]

I also considered this same problem and came up with the solution of using two 100a/25ma CT's in series then would not need to worry about a resistor.

[@jodymorgan9869]

I think the hall effect sensor only reads the voltage and axes and islanding device I don't believe it controls the wattage coming back into the system, I believe that is controlled by a internal pressure device compensating. I like your resistor idea, I would try a smoothing capacitor or it's called a surge capacitor with a diode to keep from back feeding

[@RJ-cc1fz]

Very good explanation. Correction though.. the resistor is only used to make the inverters supply slightly more of the power the loads use. It will work fine without the resistor but the grid will feed roughly 100w more than it would with a resistor used.. but when using multiple inverters (in my situation) the resistor needed to be removed from the wiring to prevent backfeeding.

With split phase and 1 CT sensor, put both through the 1 sensor, but one (red or black) longer and run through sensor in reverse direction.

[@earthenergyhex]

Thanks!

[@dwey2557]

Okay because I plan to get one of the same 2KW you have but I'm going to have to connect to sensor in series like you

[@rockstomper8390]

Hello thank you for the videos. Good stuff! OK... So lets say you have the two CTs connected to the panel feeders and your pulling 5 amps (120vx600w) on L1 and zero amps on L2. I'm thinking you will still be backfeeding the grid with 300 watts on L2 cause your output will still be a balanced output of 2.5amps L1 and 2.5 amps on L2?? Again thanks for the awesome vids. I will hit the like button right now.

I do not have a spare dryer plug. What are your thoughts on either running the AC cable directly into the breaker box, or splicing it in a junction box with some 10/2 Romex wire? When it gets to the breaker, should the ground wire from the AC cable go to the ground bar in the panel? I did not get the Marsrock branded one as you have, but the Eco-worthy and they said attach it to N. I am unsure if that is correct. Also, the AC cable they provided is only 18AWG and might get hot. Would replacing it with 16AWG be acceptable (10-13A) or did you use something else e.g. 12AWG AC cable? Thanks again for all your videos so far. They are excellent.

[@popeyeswetcactus]

In the us, there is a ground wire. Where does this go. I dont see this on the 2000G2

[@infernoal2994]

So I have a question, with 2 ct clamps in series how does the inverter know to send for example 3 amps to L1 and 5 amps to L2?

[@peterk.4266]

Hello there, how are your inverters holding up? I just bought a 2000k version, do they last?

[@redstorm6767]

Let's say I already have a grid tie solar system and the electric company has decided to shift time of use rates so that they charge more for electricity in the late afternoon. I want to use this type of setup to offset my consumption from the grid during that time, and then charge my battery bank back up during the night when rates are cheaper. My current solaredge system completely shuts down when the grid goes down. Do you know if this inverter will trick the solar inverter to stay up during an outage?

[@ischramm]

hello everything is fine? What happens if one of the phases goes off (L2 for example)?

[@dwey2557]

Hello is the 2KW grid tie inverter still working for you?
