  • It (was) alive!

    Around noon yesterday, my POCO installed the REC meter and gave me approval to use my solar array. I got almost half a day of production out of it before my SolarEdge SE5000H-US inverter faulted with error code 18xBC. SolarEdge support initially thought a firmware update would fix it, but they finally concluded that the inverter needed replaced. SolarEdge is going to "expedite" a replacement.

    The SE5000H-US reports a DC voltage of 430, sits there for a few seconds, then spits out that error and declares that the DC voltage is unsafe. The inverter would then reboot. It was stuck in that loop until we turned it off.

    Hopefully Monday I can post that it is alive.

    Maybe that was the first one off the assembly line?

    Posts like this help me feel better about the fact the 7600H-US wasn't available in time for my system. Good luck (and thanks for sharing your experience)!

      Sorry you're having trouble. Hopefully it's just the out-of-the-box mortality failure and the replacement gets you smooth sailing. Firmware-update-before-all-else (like old Windows support days of reboot your computer) is SolarEdge's goto protocol for probably everything, at least that's what it seems from folks sharing their stories. Eh, probably for good reason.

      Your installwr is involved, right? Keep us updated.

        My installer told me they have a SE5000H-US "at the shop", that they can probably swap me for. Then, they just have to hope the new unit from SolarEdge shows up before they are due to install the "on hand" inverter at the other customer's site. They have not installed my consumption meter yet, and were planning on doing that on Monday. They might be able to come out tomorrow and swap the inverter, but the meter will have to wait until Monday.

        Over all, I have been pretty happy with my installer. They did drill more holes in my roof than I liked, but they proved to me that my trusses where not a uniform distance from each other, and that was causing the misses.

        I have not paid my installer the 2nd half of what I owe them yet. They wont be getting that until this setup is stable for at least a couple of days!

          How did this turn out? I am getting the same error on my SolarEdge HD Wave 10k. SolarEdge is remoted into it now as I write this.

            The replacement inverter has been problem free for over a year now. I did have one of my optimizers go bad, back at the beginning of the summer, buy my installer came out immediately and replaced it. Overall I am very pleased with this setup.

              just got my PV installed this week, good thing I decided to go with Enphase IQ7X instead of SE. Your post really assured me that I made a right decision

                When I had one of my optimizers fail, I asked my installer how many they had replaced for customers, and they told me I was the first since they started installing them 2 years before. I asked them how many Enphase micro-inverters they had had to replace, and they said they typically replace about one per week. YMMV.

                  Did u ask them which Enphase model? Cause pre-IQ series enphase was bad, but with the new iQ series, i heard it's much better

                    My 8 month old SE3800H-US failed with error code 18xBC ("HW ERROR") three days ago. The day before it was fine, the next day no production. I got assigned a case number from my installer and are waiting to be contacted within 24h (that was 40h ago). I did not find any description online regarding this error code. Does anybody know more about it?
