  • HD Wave inverter failure

    Looks like one of my inverters is failing. It was reporting a 18xBF HW error over and over. The cycle was: begin producing (clicks), 1 to 2 seconds later it would stop and report the error, then do a 30 second wakeup and start the cycle over.

    I powered it completely down on AC and DC side for a few minutes, but that didn't help. However, I noticed it didn't error out as long as the clouds had the output down to about 400w or less. As soon as it tried to go over 500w it would trip off again.

    A Google search showed nothing for this error code. Anyone else seen this? My other inverter seems to be working fine.

    Solaredge gets an early call from me tomorrow, woooo!

    Hi NukeEngineer,

    Sorry to hear that. I checked the install manual -- which I'm sure you did as well -- of course that specific error code is not listed.

    There were several other 18x related error codes which all seemed to be power transient / ground / isolation related.

    I suggest starting to call as soon as possible in the morning when they open (time zone adjusted) to get ahead of the line. You might also try a web chat / web submission while waiting on hold.

    Best,
    Jonathan

      I agree with the above. Call them up and ask if they can provide an answer as to what the error code means. It sounds like it could be a bad connection somewhere. If there is a bad connection, it wouldn't necessarily sense the high resistance until the power got over 500W.

        Called at 9:00:07am and immediately got through. They are doing some tests remotely, but so far it hasn't made a difference. I see a new inverter in my future.

          Check your AC voltage. Might be getting up high enough to cause it to trip off. Common problem. Might have a wiring/voltage drop issue compounded by high grid voltage

            Other inverter is running just fine. SolarEdge checked that, and a few other things, this morning. They want me to look for moisture in the AC connections as well as testing for AC isolation. Will do when I get home late today.

                  If SolarEdge knows what it is, they didn't tell me. My guess is, they don't.

                      Got new inverter in, they next day air'ed it! Got it installed just before Florence came through, but it was still overcast day. At least saw it hit 2500w output, so I know that was the issue (failed inverter would trip off at 500-800w output).

                        Nice! Incredible turn around. Surprised SE shipped the inverter direct to an end user. Assume you return the defective on in the same box?

                          Yea, probably because I was a self-installer. The box said it came with a UPS return label, but I didn't see it inside, so it's probably in the packing list on outside of box. It looks to be brand new (not refurb of someone else's failed inverter), and has the newer HD Wave sticker/logo on the front. I was hoping it had the newer OLED display as well (saw that on someone else's communication board swap recently), but it didn't.

                          I'll end up keeping the DC switch cover from my old inverter since it has my stickers on it, but I can't keep the old inverter's front cover since that has serial numbers on it. So, I'll be losing my big red "RAPID SHUTDOWN" sticker.

                          It said you have 30 days to return the old inverter, but I'll get it back out to them on Monday.

                            And now my other inverter is doing the same thing... Maybe a bad production run.

                              are the serial numbers close?

                              There is a common element between the two inverters..... The installer..
