    “the quick connect AC plug may present a risk of overheating and burns in cases where it has been installed not in accordance with the manufacturer’s instructions.”

    I suspect you could apply that logic to a lot of electrical equipment that handles higher loads… Why is Sig being singled out…? Is it a bad design of plug?

      There is a Heatable video on YouTube that explains it quite well.

      I watched the video heatable did, caused by some installers using standard twin and earth but theyve took responsibility and redesigned the connector block so it’s more secure. Not sigs fault but it’s positive theyve took ownership

      there’s a notice which was issued in Australia by Sig in October 25, but apart from that it’s very, very quiet out there.

      There have been a number of attempts to get clarity, including this post, but the silence was deafening

      Ahh ok, didn’t know that, just took the notice wording as fact.

      Lets hope their forward thinking is highlighted, rather than a formal notice and the negative connotations that might bring to the brand…?

    Its great that Sig are pushing this roll out of replacement inverters. I think its a bit misleading for the messages been sent out that its an installation issue. If it was an installation issue they would be getting engineers to check the installation and change cable types. Changing the plug types on the replacement inverters points to an issue with the plugs. I do support the fact that Sig have gone to great lengths to roll the replacements out in very quick time though.

    I had not seen it, but I am glad it’s now officially recognised as an issue rather than something that is happening behind the scenes

    Yes they are active in replacing the inverters ours should be with us next week and have 21 to change. Great service from Sigenergy they could wait for failures or blame the installer for wrong cable types or sizes but they ain’t.

    Do they actively contact owners , or do we need to try and establish ourselves, if we have this product version?

      I’ll assume we are not affected, unless our installers make contact. Much appreciated.

      they are contacting the installers of 8, 10 and 12kw inverters and asking for the installers to make arrangements to replace within 14 days.

      All of these inverters are being actively monitored.

    I’ve spoken to my upcoming installer and they confirmed they’ve already corrected all of their 8,10 and 12kw installs. Installers should have already contacted customers or should be very soon

    Yes this has been happening for some time to have the inverters replaced, no different to car manufacturers having recalls, great to see a solar company facing into an issue they have found and spending the money to have it rectified. To me that shows a company that wants to be around for a long time!!!

    This would apply to anything electrical, solar, workshop tools, tumble dryer… anything that uses high power
