I have a 24 inverter (provided by inverex) model name: Axpert VM 3Kva Plus . it comes with USB port only. I tried to flash new firmware to it but it failed. so I opened it up and found that there is USB to SERIAL board inside inverter I just took it out and replace it with simple com board from another inverter and now I can flash it with out any problem. The reason that some inverters dosent flashes through USB port is the USB to SERIAL board that is restricted to 2400 baud rate so the inverter can communicate to pc monitoring software but cannot be flashed via USB port because flashing is done with 9600 baud rate. so if anyone want to flash inverter firmware and don't have com port on inverter you just have to replace the USB board the with com board from any other inverter and flash the inverter with out any problem. USB to serial board of my inverter is attached

Thanks alot

Thank you very much for reply. Pease let me clear if we flash wrong firmware to the inverter is there any chance of frying(hardware damage) the inverter.

Hi all I have few questions about axpert inverter Is there any way to read and backup the existing firmware from inverter before flashing new firmware. so in case if the new firmware is not compatible, we may restore the previous one. if we flash wrong firmware (main firmware) then what will happen. does it bricks(hard brick) the inverter or we can reflash it using com port again or have goto customer care. what if we don't have com port on inverter. Is firmware flashing possible using usb port. Regards
