Inverter with no serial number

Is there help with an inverter that has lost its serial number? This was in the hands of Giv Ltd at the time of administration.

You could try your installer, they may have the requisite permissions to set the serial number, or it could well be a givenergy support feature

IVoltz Unfortunately, whilst GivEnergy remains in business we cannot help you to set or change a serial number. GivEnergy's stance is that installers are not allowed to change serial numbers. You need to ask GivEnergy for assistance, sorry.

Only once GivEnergy is dissolved as a business can we assist you freely without risk of legal action being taken against us.

It should be noted that an inverter can be controlled locally by third party tools regardless of the serial number.

My issue with AIO (Need someone who's tech savvy ) - using the local app I can connect to my inverter but my serial number is not recognized. I've scrubbed the IP and No. from the image for security. But you can see I get XXXXXXX for the serial number even though you can also see that the AIO is regestered to the App and its the correct Serial Number its looking for. I need technical help on this I think, Ideally someone who has seen this fault before and fixed it. I've now followed a few web site tutorials and not got an answer. I've tried updating firmware and the dongle - this has worked i.e. I can update and get to settings ! I can see the Inverter on my network and connect. I can update my wifi settings via a web browser - They are correct as per tutorials I have found - and as I can connect with the App locally and find my inverter this also seems to be correct. I've even connected my laptop to the AIO system via USB and Wifi to change dongle settings and looked for the MSM file on the system to check this txt file is set correctly. This corresponds to my Dongle Serial Number and and my external serial numbers on the Inverter is correct and aligned. But I cant use my system and get an error see - images

tumblefatboy Have you tried going to the GivEnergy Portal to see if it is recognised there? https://givenergy.cloud/dashboard
