18kPV is on the CEC list with CSIP approval & is available on the SCE list as of today !!! Thanks Sig Solar team.

@SignatureSolarJames I have one question, when might the 18kpv get CSIP approval. I'm in LA county with SCE & they apparently require that approval for grid tie.

I believe that is the inverter rated power, technically 11.933kW

oops there it is on the top right of each list

Tigo or other brand of disconnect device. Tigo dual is a decent value TS4-A-2F under $50

I was hoping that SCE would have it listed as well, but, alas, still not listed ... :unsure:

Wacky idea, find some way to load the panel voltage down when it gets above 150v. Some kind of temperature sensitive power resistor.

That is interesting. I am on the CEC web page but do not see the spreadsheet with all the columns. Where would I find that?

This 10k rule seems fishy to me. For CA roof mount it depends on rafter vs truss and spacing as well as many other details. See CA Solar Permitting Guidebook as an intro. For gazebo, I would guess it will require a structural engineering approval, but only way to know for sure is to contact...

It says not schedule 80. I'm not sure how strict the fire inspector will be, but it would be nice to get something that is actual schedule 80 in the event that they can tell.

I believe that off grid does not connect to grid so you would not need to go through utility approval process However, one must also consider fire dept and AHJ approval if getting permitted. And if there is a fire, will insurance cover it? Home sale may also be a concern worth considering

I didn't see any that specified schedule 80. Let me know if you see any that are

those look interesting. I also saw these Red Head anchors at Lowes & HD that seem similar & include the threaded part & nut

I believe this is what we have been waiting for.

Cool. I'll check them out

Wow that sounds scary. Thanks for the warning

all seem to be thinner than schedule 80. I guess I'll google some local welders. Should be interesting ...

Technically the 18kpv12l has a built in dc disconnect that is controlled by the RSD switch on the side or a remote switch so technically adding an external dc disconnect is not needed, but older requirements may not recognize this as an allowed solution. For example The CA solar guidebook single...

Hmm, I don't see any EG4 batteries listed or am I missing something? Perhaps we waiting for a CEC website update?

Well, I was looking for the PowerPro or any EG4 batteries on the CEC list. All I see on the PowerPro link is a 1973 cert for LL batteries? Shouldn't I be seeing EG4 on the list below where the red line is? Or are we still awaiting a CEC website update? They should have done an update today.

9540A testing is for the battery alone. Many batteries have 9540A. 9540 is inverter + battery tested together. You likely need 9540 to get permitted. 9540A alone is probably not enough. EG4 is unlikely to test batteries other than their own unless there is some special agreement. If Ruixu is...

Others may know more than me, but the first question is how is the 18kpv wired up? If you are you using a backfeed breaker in your main panel the 18kpv will turn off the grid connection when power goes down so any loads in your main panel will also go off. The battery can still run any loads on...

18kpv PCS issue is a risk in CA. Although I am SCE, I'll be interested to see if you can get approval as there are some odd info requests on the SCE application.

that is correct

Hi All. Was wondering if anyone has gotten approval from SCE to grid tie the 18kPV in CA / LA county? I'm considering buying the 18kPV + PowerPro battery, but I don't want to spend all that money and up with a system that cannot be grid tied as I will more than likely need to backfeed to power...

Some in CA are having approval issue as 18kpv apparently does not have PCS certification. Details in this thread. SS has suggested a potential work around but it is unclear if it would be approved by PG&E or the other large electric companies in CA

If you need to have a 9540 certified system, the Riuxuwould be problematic.

Maybe you are confusing rail mounting with panel mounting. Only the rail mounting hardware needs to be spaced at 4', not the panels. Panel spacing is whatever will fit on the rails with the panel mounting hardware. Rail to rail spacing is dictated by the panel height or width if the panels are...

@SignatureSolarJames Any word on that CSIP approval?

Probably not. If you download the CEC spreadsheet and search PCS you will find many inverters with PCS shown in the description column. The 18kpv doesn't show PCS in its description cell unfortunately.
