Thanks for such great advice folks! The electrical contractor I used for my meter/main upgrade referred me to one of his NEC graduates (contractor teaches NEC at local community college) and making contact with him was very beneficial. Turns out he now works for a large solar company but takes...

I suppose there would be problems for a homeowner if trying to hire a consultant to help plan/engineer/permitting a DIY system or help with choosing and installing DIY equipment. We are specifically focused only on code compliance related questions and navigating NFPA/CEC/NEC/IBC/AHJ code. I'm...

I was planning on using the TS4-A-F (RSS) and not the TS4-A-O MLPE as it seemed that recent modules do so well themselves with shading anyway. I recall coming across a YT video of someone comparing two side by side modules with and without a TS4-A-O and the one without the Tigo produced more...

Ahh, so even if it is on CEC list and passes AHJ plan/permit SCE could still prevent it with/during their Interconnection application or review process? Hmm, well for this first install stage on detached garage alone I wouldn't want or be doing an Interconnection agreement with SCE unless I will...

The garage loads are non-critical. I wouldn't even care about charging the battery via AC/grid. Whatever PV makes I could use and/or store. When we get to the point next year of installing PV on the house and connecting critical house loads to the inverter(s) then doing Interconnection would...

We are interested in hiring a solar consultant that is knowledgeable about building a code compliant system in the Los Angeles area. Specifically we are interested in maybe a Google Meet/Zoom call of up to 1 hour or so to discuss what we wish to do at our residence and how to maintain code...

Is that a good thing or a bad thing? :) We are not interested in locating a solar installer/installation. We are interested in DIY, I thought that was the purpose of this forum, no? Solar installers in our area are only interested in selling and installing their equipment, all microinverter...

Thanks! That's great advice. I intended to use a planning/permitting service when I get to that point but I just assumed that all they do is take your list of equipment and specifics about the project and prepare the engineering plans and/or permit and that's it, regardless if it will pass...

Thanks! TS4-A-F or TS4-A-S was the plan, but one of my code related questions was whether a RSS was even required for a detached/unoccupied structure. We will use them regardless but was curious if no setbacks are required why would RSS be, who would be up there? Yea, I've found 9540 a whole...
