February 26, 20251 yr I fully agree, don't change it unless something broken. My system was installed a number of years ago. Have never updated firmware. MdF Edited February 26, 20251 yr by MdF
February 26, 20251 yr I have no need to upgrade nor do I plan on upgrading for the hell of it. I'm just curious to know about any new features (if any) or info that might become available in newer releases. I guess I'm more surprised by the number of upgrade requests that are posted daily. Some of the installers/experts don't know how to configure time of use or other "basic" settings, yet the first thing they request is a fw upgrade.
March 16, 20251 yr Here is a overview about all firmware files: https://github.com/Mights001/DeyeFirmware
April 30, 20251 yr Just added my invertor 6kw hybrid 3phase:HMI: 1001-C049MAIN: 2006-1147-1807ARC: VerD207
August 8, 2025Aug 8 I just got a Deye 5kw and managed to add it on Deye Cloud. It shows my account as Super Admin yet I am unable to select Firmware Update. How can I get my account upgraded?
September 26, 2025Sep 26 I came across information somewhere that Deye is working on reducing the inverter's own consumption when the load is powered only by the grid. That is, UPS mode.Has anyone noticed this in the new firmware?
