I got this firmware directly from Andy at EASUN. The reason was that the USB interface on my inverters does not work correctly. The inverters have the following firmware Main 05401 Slave 04022. A new inverter has the following firmware Main 05600 Slave 08025. With the newer inverter everything works as it should be. The USB interface works correctly and the data can be retrieved with the solar display tool. The older firmware has an error that is represented by the fact that the USB interface after one to 3 hours simply "falls asleep"! The device is then no longer displayed and the Raspi says that he can not open the port. The port is then also no longer displayed with lsusb.  If I then press and hold the left button on the inverter touch display, the inverter shows a warning "No File" and then the interface works again for an indefinite time. The firmware which is included in INFINIVIV5.6KReflash5600 should fix this problem. Unfortunately it did not work. I do not dare to test it again with another inverter because the first one is already defective.
