Rob Gard Posted July 1, 2020 Share Posted July 1, 2020 I hope someone can offer some help as any technical assistance from Imeon in Cape Town is non-existent. My invertor connects and disconnects from the grid every few minutes for no apparent reason. It doesn't seem to be overheating and both fans are working fine. It will all be functional, and then the 'AC Grid' logo flashes and connectivity to the house from Eskom is lost. Supply either comes from the panels or batteries at this stage, and then a few minutes later it reconnects again. Any suggestions, or info as to who can do invertor repairs in Cape Town will be appreciated. Quote Link to comment Share on other sites More sharing options...
francois Posted July 1, 2020 Share Posted July 1, 2020 (edited) Hi my Infini 3kw did this when I had it installed. The issue was that the grid frequency on some occasions went above what the limit was on the inverter. For instance the limit on the inverter was 50.3 and the grid would go to 50.4 or 50.5. I had to increase the grid frequency limit setting on the inverter until it no longer disconnected from the grid. Not sure if this is helpful. Can you access any logs on your Inverter?

Rob Gard Posted July 14, 2020 Author Share Posted July 14, 2020 Thanks Francois. Apologies for only replying to you now. Any idea where I can set the grid frequency on the inverter? I have Imeon Manager Ver 2.2.2, but haven't seen this function anywhere. Quote Link to comment Share on other sites More sharing options...
francois Posted July 14, 2020 Share Posted July 14, 2020 Hi Rob I am not sure, but does your inverter display any error messages on the display when it loses AC connection? There is a whole table of error messages in the Imeon Manual: If there is a specific error code on the display it will help to narrow down where the problem might be.

Rob Gard Posted July 16, 2020 Author Share Posted July 16, 2020 Hi Francois, No, there is no error displayed, and even when I log the data it doesn't come up with any error message. It only shows that it's not receiving any power from the grid. Quote Link to comment Share on other sites More sharing options...
francois Posted July 16, 2020 Share Posted July 16, 2020 Do you perhaps have a prepaid meter? Your inverter is not maybe setup to feedback to the grid? It can cause a prepaid meter to trip. Not really sure what else you can look at, sorry. Quote Link to comment Share on other sites More sharing options...
