I am changing my battery storage from the tesla powerwall 2 that came with my system and adding to the ruixu battery storage I installed with the solark assuming I can figure this out. SRP has a DER storage meter which per the DER rep at SRP only sees if the system is charging or discharging...

the panels will be angled. slightly for run off on an individual bases and slightly angled away from the house. I think im going to do a metal subroof under it for full shade and to hide wiring. we get monsoons that can have pretty high gusts in the 60s+ but not continuous high winds. Ill attach...

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

Wall is non structural. basically a block fence that divides the properties but it would not be incorporated into the structure. may go with 4 posts and do the foundation connected between them like 48"x12x24d. I already have an auger drill that I used for my pergola foundations but that was 12...

Thanks for that feedback, I really want to avoid doing 4 posts if possible just for the spacing in the area as under it I want to build an outdoor kitchen area underneath it, its going to go in this area next to the pool equipment along the wall towards the house. an extra post would make that...

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 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...

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...

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...

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.

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.

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

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...

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...

the tesla system is not liking to be ac coupled through my solark so gauging interest in parting with this. Im open to discussions on shipping I have pallets available to pack for shipping if necessary. shipping will be the responsibility of purchaser to arrange pickup. Located in Phoenix AZ...

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...

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 was incorrect that a breaker was available with a 3/0 post. up to 100a breakers only have a 2/0 max post. any suggestions on fixing this issue. its going into a simens solar ready panel that came with a 70A solar breaker and will accept up to 100A breaker. I do not need more than then 70A but...

Has anyone used this vendor or have any reviews? their pricing seems almost too good to be true.

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.

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.

Thanks for that feedback, very good to hear

I read though some code p3103.1 that now allows for installation over plumbing vents as long as there is enough spacing between the top of the vent and the panel and now the vents can be cut to 2" above the roof line. I will likely reroute these to go out the top of the panels so I dont have...

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

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...

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.

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...

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

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...

Thanks for that insight. is there a calculator or way to monitor total load to see if its possible to derate my main to 125a?

if your last statement means if I want to go offgrid? I think I would be ok for an outage without much issue with just the solark pv system. if it was longterm SHTF situation I would just reroute the enphase system directly through the solark so all of it could be utilized since at that point...

pretty certain that I am going to go with the solark 15k inverter and not touch the existing system other than to be able to charge the battery with the additional panels. Assuming I de-rate the main breaker to 150a would I be able to max out the solark 15k with the 19000w input (would be about...

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