First of all, Merry Chistmas to all of you!
I have been waiting for the firmware upgrade for my inverter for a very long time. Thanks to your upload, I was finally able to use it. My inverter is a ISolar SMV III 5KW. It is basically a clone of the Axpert VM III 5000-48. My previous firmware was
U1 41.15
U2 02.40
After the upgrade, this is the new version:
U1 41.16
U2 02.61
The issues with the fan speed are resolved. Thank you very much!
