this is resolved, the tesla still does not like working as a slave system, its working as well as it can be currently but when doing time of use it just dumps until empty even if its just selling back to the grid and not using the power for the house as desired. It will be replaced with...

Ill be installing my second system, the original system didnt have any issues with vents as it was completely over a living room and bedroom. but adding 19kw (hopefully, im running out of space) to my existing 7.4kw system.

Srp does not have a limit, just limits how much they pay for any excess production

for 18kw of panels you only need 1 solark 15k (19200w max input pv per spec sheet), batteries are where I am thinking ill be limited with one solark but will be going likely with the eg4 or ruixu 30kw rack in addition to my tesla batter from the original system.

Thanks for all the help, system is up and running, peak production I have seen is in the 17-19kw production (I have east and west facing panels so we will see what summer holds) first bill after getting the system completely active and running properly was negative was only active for 3 weeks of...

Thanks for that, mine will be 100% flat mount, do you think your conclusion of 7cf per panel is necessary for that?

I didnt just add a solark. I also added 30kw of ruixu batteries and 19.2kw additional pannels. Originally I was going to stay all micro inverters but it would have required me to do a lot more changes to the original system than I wanted to. Unfortunately that choice has come with other consequences

Thanks for that feedback, very good to hear

I would be interested in a referral if the person you used is still doing diagram work.

The second example is likely what will be done. I was talking to someone locally about exactly that. Just trying to make sure it doesn’t void the warranty through the original install. Still considering a second battery option as well

dont believe the enphase/tesla gateway system has that sort of capabilities and I would lose most of the features of the solark by doing so even if it would be possible.

7.4kw on the enphase system, it has to be ac coupled only way it can go into the solark is through the load or gen inputs. generator is what is recommended by solark as it can monitor volume of input from that where it can not from the load input.

either I'm not doing something right or its not possible to de-rate my panel at all... I guess my only option(assuming my calculation is not wrong) is to go to a 400a main panel which I am not sure is something I really want to undertake to pay for a 400a power service that I do not really need...

finally got my solark 15k system up and running. my previous enphase system with tesla battery is running through the AC coupled side and its REALLY not happy to be there. the tesla gateway 2 thinks its offgrid (confirmed with Solark this is a known issue and no fix available) and those solar...

are those subpannel setups able to be backfeed systems? ideally im going to have to go through the DER process with SRP eventually though I probably will get the system up and running offgrid first as I need/want the benefits asap to help with my summer bills

weight of the panels is sub 50 lbs each 41x69. we dont get much in the way of adverse weather but we do get monsoons that can give some fairly strong winds occasionallly. would use 4x4x0.25 wall tubing, 24" concrete footings 10" diameter is what I was considering.

I am just using your suggestion about the previously mentioned subpanel. I don't really have any thing specific as of yet. unfortunately the brilliant installers of the original system clustered nearly everything right up against my existing main panel which will make everything much more...

first of likely many questions with this project of adding to my existing system. I currently have 20 rec370 panels on iq7+ inverters (30.25a) and a 200a solar ready main panel with a 70a breaker on the solar. I am going to add 31 455w panels on iq7A inverters (44.95a) all will go to the same...

Also I just noticed the main panel has a max 100a on the solar bus, so even if I derated to 125 this would not matter as I could not get the necessary 115a on that busbar correct? so a second panel of some sort is going to be necessary.

Likely the route that I will have to take. only had to do 3/0 due to distance from solark to main panel understandable, this is the grid line from solark to main panel. This is our long term solution most likely per my electrician. wish they had a 3/0 to 2/0 he doesnt like that it steps down...

I am trying to figure this exact thing out currently, my enphase 7.4kw system is ac coupled with a single powerwall 2, just got the system up and running and currently what the ac coupled wants to do is push the tesla storage to charge my ruixu 30kw batteries. I added 19.24kw on the solark in...

no, and it is not liking being ac coupled the tesla battery thinks the grid is down and as such disables the solar panels connected to it.... its been frustrating at best. either going to hook it up to the main pannel and run two separate systems or sell the tesla battery and just put my enphase...

I believe its a 100a solar bus. Its less cost effective to change the existing enphase system and go to a different inverter setup I did the breakdown. Less than 3k for the iq7a inverters I needed vs ~16k for two 12k solarks that would be needed for the 21.5kw of panels

following Ill be doing something similar to your setup thanks for asking this question!

I am looking to finalize the last 10 panels that are to be added to my system. was considering building a T post style structure to support the remaining 10 panels. Was considering 4x4 steel uprights and an I-beam square box up top to mount the rails to. has anyone built something similar I am...

Thank you for your patience with me as I figure all of this out and all your insight its been very helpful. I will do a manual test on the loads on the house tomorrow night. I have referenced the diagrams from previous in the post, though its still a little greek to me as I expand my knowledge...

system already has a tesla battery.

the tesla battery is already in with the original system, unless someone wants to buy it not really worth the time/effort to remove it and change it at this point unfortunately. also its a tesla powerwall 2 not a powerwall plus. no inverter in mine

great question, that I do not have an answer for but I know the person that physically sourced every single part for the Powerwall while working for tesla I can ask him.

assuming I am willing to spend the extra cost and not use enphase on the new portion and go to a aio inverter. would you go with solark or eg4 or something else?
