    Pls help! Solar system dead for 2 months and nobody will help

    Greetings,

    We are desperately hoping someone here can point us to a solution to the solar quagmire we find ourselves in. The story will be a familiar one, and I will truncate it as much as possible. And, for the record, we live in the northern part of Santa Barbara County, in California, USA.


    A few yrs ago, “Company A" put in our solar panels. Then, about a year ago, we got solar batteries and a new Solaredge inverter from "Company B."

    Two months ago, our system completely crashed, and is still dead. The inverter has a persistently flashing red light. When we contacted Company B, their terse response was that they had spoken to Solaredge and that they confirmed that the "issue is on the solar side, specifically on the panels leading to the inverter." So I take that to mean they regard this not as a problem with the inverter that Company B installed when they installed our batteries, but rather is Company A’s responsibility.

    So we contacted Company A, and apart from informing us that they are booked up until April, they refused explicitly in two separate communications to investigate the situation any further on our behalf. In fact their exact words were as follows:

    "I have looked at the site and it appears that there is a ground fault. This fault can be anywhere within the system. To detect a more precise location of the fault, a special setup within the inverter has to be used. I don't want to touch the inverter from [Company B] because they can put any future fault on me. My recommendations: Ask them to find out where the issue is exactly.”

    So we are stuck between two companies who emphatically refuse to take responsibility for or investigate the situation and help us resolve it. By the way, we also contacted Solaredge directly and their response was basically the useless "contact your installer." We were hoping they might exercise a little influence on our behalf, but unfortunately they chose not to do so. There has been only a tiny amount of additional communication regarding this matter because what we have started to get when we contact the installers is “that is not my department, but I will forward your query to someone who will contact you,” but of course they never do.

    So what do we do now? We plan to file a complaint with CALSSA, but we wonder if CALSSA might basically be a “do nothing” solar power industry public relations agency that is more geared towards advancing industry interests as opposed to consumer interests (though, yes, you’d think the best way to improve an industry’s customer service reputation would be to make sure disgruntled customers like us don’t share their horrible solar experience to absolutely everyone who will listen, whether they want to or not).

    My questions: Are there any other solar power consumer interest agencies (i.e., conspicuously aimed at advancing consumer interests and resolving consumer complaints) that we should also file our complaint with? We have spoken to a lawyer about our situation, but for now tend to regard legal action as a “last resort” kind of option, and are so far reluctant to pull the trigger on that. Our lawyer is, however, willing to send a “request for information/action” letter on his law firm’s letterhead, as several people have told us that the mere whiff of attorney can produce a response in these solar power situations. Are there any class action suits against installers we should be aware of? As I said, we live between Santa Barbara and San Luis Obispo in Southern/Central California, USA, so if anyone in this forum happens to know of any technicians, activists, agencies, or lawyers (with experience in this arena) in our vicinity who can help us (they will certainly be aware of Company B's reputation, by the way), thank you SO MUCH for letting us know about them!


    It is a horrible testament to the appalling customer service practices of the solar installation industry that after spending thousands of dollars trying to do the right thing for the environment, we are still “grid people,” and a very cautionary tale.

    For me, the problem has been truncated too much.

    What was the first system? equipment model numbers, schematics, etc. When was it installed?

    Exactly what is the second system? And besides installing equipment, did the installer do anything else? What was the project they sold you?

      Hire Company C to find the fault or other problem and have it fixed. Now you are back on line and know whose product is at fault. Next take your claim to court backed up by the written notices from Company A and Company B.

      If it truly is a ground fault, any good electrician should be able to track it down post haste. Don't wait around for those yahoos....take the bull by the horns......

            Get both companies to be there at appointed time. Company A investigate the array and lines up to the inverter and liase with company B with all inverter related settings etc. That way, neither can point fingers because each is handling their own area.

            Ground faults are commonly before the inverter connection either due to damaged or degrading wiring or possibly panel failure.

                OP here.

                Thanks all! Yes, getting both companies here at same time, getting them to liase with one another, or at least communicate with one another would be great, but they absolutely won't do that. We have made that exact suggestion. We are 45 mins north of one installer, and 45 mins south of the other, so I suppose that is partly why they don't want to send any technician out. That may be reprehensible enough, but the fact that refuse to even contact one another is just appalling! We are looking for a good "Company C" installer to come to our rescue, but since we have already done a rock-bottom horrible job picking the first two installer, if anyone knows any reputable installers in my area (northern part of Santa Barbara County, California, USA) feel free to recommend! Just filed a complaint with CALSSA (California Solar & Storage Association), so we'll see if that gets any action, but we are not optimistic. I assume they will give us the same response Solaredge did: "You should contact your installer."

                  Yeah that's what we call hit and run companies. Tried writing in direct to SolarEdge? Explain how installing their system somehow caused your system to be untouchable.

                    Yup, tried contacting Solaredge right at the start. Told them the whole story and their response was something along the lines of "Contact the installer." And, yes, we had just told them that we had repeatedly contacted the installer and the installer was non-responsive. I was hoping Solaredge might intercede on our behalf becuz they must have some kind of relationship with the turds who install their product, but I think what we got was auto-reply boilerplate.

                      Like stated earlier find a qualified electrician to isolate and find your ground fault doesn't have to be a "solar" guy.
                      Just like any problem you need to divide and conquer as they say.
                      A good electrician should be able to assist in finding your problem.

                      How many panels?
                      How many strings?
                      Panels on roof?
                      Asccessible?

                      Sounds like you don't have micros so it's either a panel or your wiring is damaged. Or your "Company B" is wrong and it's on them.

                      If I didn't live in San Diego I would come over and help you but it's a bit far.

                      Turn your entire system off, everything.
                      Next go and unplug every solar panel you have.
                      Keep the 2 pole breakers off that tie into your solar panels too.
                      Reenergize your inverters and see if the GF is cleared.

                      If it's now clear you know it's in either your distribution wiring or a panel.
                      Now turn your 2 pole breakers back on. If no issues start plugging in your solar panels one string at a time and see when the fault comes back.

                      Might be something obvious like a raccoon chewed on a portion I don't know.

                      Be proactive not reactive.
                      Alot of smart guys on this site. Just give them the info we asked for and we can walk you through it.
                      Was a Union Electrician and contractor so it's not rocket science, thank goodness.

                        People can make suggestions, but we have to know what we are dealing with. Troubleshooting is a process. My experience is that most 1st level tech support is not very useful. Technicians from two different companies are not going to look at a system problem to get to root cause, but to determine their equipment is not at fault.

                        I'll re ask my original question to the OP.

                        1) What was the first system? equipment model numbers, schematics, etc. When was it installed? Was it functioning? How long was it functioning?

                        2) Exactly what is the second system? And besides installing equipment, did the installer do anything else? What was the project they sold you?

                        Was system #1 stable, for how long, then what changes were made to system #1 that made it into system #2. Were there any events causing system #2 failures? Exactly what is the fault of system #2? I think arc fault is too broad a category. A SE fault code would be way better?

                          Have you checked the ground fault fuse in the inverter?. I had to replace one in a SMA inverter due to damage to DC wire also have replaced GF fuses in Schneider CC's. After checking the system I believe problem was caused by disconnecting batteries while still having solar input.

                            OP here again.

                            I can provide some of the info oregon_phil requested.

                            The initial system, installed about May 2018, consisted of 25 panels, LG NeonR,LG350Q1C-A5. It is an easily accessible ground mount. That was done by "Company A."

                            When I say "2nd system," what I mean is that "Company B" added two LG Resu batteries to the existing panel system, and swapped out the original Solaredge inverter for a new one, the full parts # of which is SE7600H-USSNBBL14. The batteries and new inverter were installed in early 2022, maybe January.

                            Our system stopped working completely on Nov 13, 2022. One thing I didn't mention before is that some time a month or before the full crash, I happened to be checking the app, and noticed that the system was not producing, though it was plenty sunny out. I happened to notice the outage only minutes after it had occurred. We contacted Company B right away, and they gave us the usual "We'll pass this along to our service technicians and get back to you right away" but of course they never do get back to us. However, about three hrs later, the problem resolved itself. We wondered if maybe they reset something remotely without telling us, but the more likely scenario is that they did nothing (they never followed up), and the system somehow "fixed" itself. No idea how the system "fixed itself" as if by magic, but that scenario, however unlikely, is far more likely than one where Company B would have done anything to help.

                            And thanks all for suggestions on how to troubleshoot this myself, but let me assure y'all: There is no way someone with my skill set should go anywhere near the electrical components of this system! I actually do have pretty good range of home repair skills, and can do some "in house" electrical work, but anything involving power originating from the panels and coming into my house is terra incognita for me! Plus, I am always afraid that I will do something wrong and void a warranty.

                            I glanced at the underside of the panels a while ago to see if I saw any chewed wires, but at the time I did not see anything obvious. But I will check again with more diligence. I do live in a rural area with a massive amount of wildlife.

                              Ok that is much clearer now. Four years had elapsed with no issues on the panels and the wiring so its not Company A's incompetence or fault anymore on the system. The panels may have long product warranties but the wiring and system install may only have normal 12 month warranty. Normally the installers have to register the modules and units with their system UI from solaredge and the moment you switched out, company A no longer has control nor responsibility. How can they? The entire responsibility of the system transferred to you and when company B installed the battery and new inverter, it was their responsibility to ensure everything is up and running properly. Whatever happened before the inverter swap is no longer relevant. It is now up to B to resolve the issue and any fixes to the system before the inverters would be billable to you.

                              Yes you shouldnt touch the system if you do not know what you are doing. DC wiring from arrays are very dangerous especially with big arrays. Only a certified solar installer should handle it. The most u can do is ensure the cables are properly plugged in and snug (with rubber gloves). Do not touch any metal parts because you already know something is being grounded.

                              If both companies are so hard to deal with, find another company to troubleshoot.

                              IMHO, from the symptoms you have described, I think a wire may have been knicked and caused arcing which shorted out the system on high output day.
