Previous post was incomplete, i am making new one with more details.
This is my first solar system installation and I guess i bricked my inverter i dont know if it is my fault i am pretty sure that i followed all the instructions carefully
At Powland site i found that for "batteryless firmware".

I made the update succesfully but after that the inverter is dead.
The display is off,buttons are not doing something, neither the on/off switch.
The inverter seems off,no ac output any more
The wifi rs485 is powered,3 leds from 4 are on (power,net,com) but the 1 (srv) is off and at the app, the inverter is not online
The pc finds the connection with the otg cable but i cant do anything.
I have know the inverter stand alone not connected to anything only in otg cable and this is what ia have

This is not real,no PV connected to get power from

I am quite sure that the fault is the firmware was faulty or not installed ok.So i tried to contact EASUN or the reseller with no success.I can see that many other in the forum enjoy the no support of them
Is there any way to flash a working firmware?Do i need extra hardware and software to do that.. maybe a rs485 usb cable to re flash the inverter

I went step by step according the pdf"If the machine works normally, do not upgrade this firmware. The current firmware is only upgraded when there is no battery."
