February 25, 20251 yr Hello guys I want to ask how can copy firmware version from one inverter to another for same model VMIV TWIN6KW? Because I need old version back ?
February 25, 20251 yr It's not possible unless you have a 128-bit password. What firmware do you need? I have a fair collection.
February 27, 20251 yr On 2025/02/26 at 1:59 AM, H.khalif said: U22220 That's display firmware version 22.20. It's the same display firmware as used in Axpert Max II models. It's available from this very forum: Just ignore the main/DSP firmware version 56.06, which is for a Max II 10kW model.
