Did you buy the spare parts from Easun ? If so how and where ? Thanks

I have 3 IGrid these are hybrid. They can be off-grid as well as on-grid and they can feed into the grid. Optionally via a parameter. Are from this year. However, I still have the problem that I can not upload the firmware for the main CPU. About the rs232 can only update the display firmware.

All of my serial starts with SN96132…….

This is Display Firmware for IGrid SV IV V80.26. In Directory Remote panel-3573-220926 pw12345678

Hi, try 12345678 lg Michael

It came with the good firmware from the factory.

I use the original RS232 cable that came with the inverter. Flashing the display firmware works fine with the cable and my USB converter. Only the installation of the DSP does not work. If I try the OTG interface error 03 comes. I have only the dsp.hex in the root on the Sick. Formatted with Fat32. I would like to bring my other two inverters up to date.

Thanks for the information. What type of USB stick works for you ?

How can you flash this ? About OTG with the Micro USB interface has not worked for me. If I try it via the serial port (RJ45) connector with RS232 to USB adapter always comes only an error message no connection. So only the flashing of the display firmware works.

Is the firmware I got from Easun main firmware or or display ? I assume that this is for the mainboard. If you generate the .hex file by executing the batch file, a dsp.hex is generated, which actually speaks for a mainboard version. If so how can you flash this. About OTG has not worked for me anyway.

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.

Hello, Yes that's right. I mean warning 32, but the result was that the inverter no longer works. I tried to install the firmware via the OTG interface. The display showed only the warning 32 and I could also activate the update function. The display shows UPG, but the update does not start. Either the message bad file appears, or nothing happens. The display firmware can be updated very well via the serial interface. I also have a STM32 adapter with which I can read and write directly on the display board. However, this does not work on the mainboard.

Hello, I have 3 inverters from EASUN. One has the same firmware as in the photos in the article. The other two have older firmware. With the two older versions, I have the problem that the data retrieval via the USB interface no longer works after some time. It is as if it "goes to sleep". The interface is then no longer active and is no longer recognised. The inverter with version 280.25 and 156.00 works perfectly. Is this function in the communication board or in the main CPU? So can I fix this by flashing 80.25? Thank you for your help. I got the file in the attachment from EASUN. This is supposed to be the main firmware 156.00. An attempt to flash via USB failed and ended with error 32. INFINIVIV5.6KReflash5600.rar

Thank you for the answer. But the problem is the missing com port. Neither Soalrpower nor Watchpower work without it. Actually, a USB to serial adapter should be recognised. Instead, an HID input device is recognised.

Hello Watchpower does not work with my inverter. When I connect the inverter to the PC (Win10) via Micro USP, it does not appear as a COM port but is recognised as a USB input device. But Watchpower expects a COM port. Is there a special driver or how else does it work? LG Michael
