jarjarbeens got a reaction from aamilev in Remote Panel Axpert 5kW VMIII (Probably Bricked)Hello all,
Good news. Finally succeded to re-flash my remote panel and make it work again!!!
These are the steps that I followed.
1 - Connect all (PC to Inverter via RS232 to USB cable) with no power supply given to the Inverter (No battery and No AC IN).
2 - Have RemotePanel_Reflash_MCU SW prepared on PC. (Correct COM port selected)
3 - Provide power supply to inverter (AC In) and immediately (only few seconds after) click on "Update MCU" button in RemotePanel_Reflash_MCU SW.
After steps 3 I started seeing that flash started. More or less after 10 minutes the flash was completed and LCD remote panel was working again.
Thank you guys for the support given. Probably this thread will be useable for someone that will experience same issue in the future.
