Growatt SPF 5000 ES firmware


Recommended Posts

Hi All, need your assistance. I have the above unite purchased in Jan 2023 which has the serial number starting with JNK, which has firmware version:

067 01 1.04

068 01 1.04

My issue is the fan run at full speed 24/7. Reading trough various post, i came across one that states the firmware should be upgraded for this issue to version:

067 F4 A27

068 F4 A27


Need your assistance with either the required files for this version or the site where I can download them including the upgrading process.


Thanking you in advance.
