Good Day All So finally got the time and the motivation to try an upgrade on my Axpert. So the reflash tool runs and opens the port but after that it fails on connect error. Does anyone have a bit of advise on how to proceed?

Thank you very much for all the quick and satisfying replies. I will try as Coulomb suggested. And get back with the results for these inverters. To answer the questions...

Good Day All I have Exact same model as shown. Bought it a year and a bit ago and it still works. Have had some issues like the Error 90 and some burnt components. @Brian J Did you achieve or receive any info by emailing them? @weber Do you guys know if the firmware works on these. After the Error 90 I received a new CC board from them and installed it. This passed weekend I also installed a pylontech 3.4Kw Battery. I also set the relevant settings on the Inverter as suggested by Weber in one of his posts. But to the point, I get fast switch overs as soon as the sun gets low and have to manually change Preferred Output Source (Setting 1) back to utility to avoid the flickering of lights. I suspect that it has to do with how the inverter measures SOC of the battery as the Pylontech never drops below the first LED on the SoC Status. The load is about 1.1kw All the time. and I have 12 * 275Watt Solar panels on the Roof. It currently has v 72.40 installed on it. Any suggestions? Will other firmware possibly improve my problem?
