Hello all... first post.
This evening, I reluctantly tried to update the firmware on one of my EG4 6500EX inverters starting with the display.
DSP FW version: 79.02 and Panel MCU version: 61.02
After many, many attempts to update with adjusting baud rate (slowing it down from 9600, 4800, 2400), FIFO speed, changing COM ports, etc.
the update will start but randomly stop at various percentages. This screenshot shows 28%.
Sometimes, it's 6%, sometimes, 12%, sometimes in the mid-20s, and one that was 34%.
The inverter is down now with an error code 32: Communication failure between inverter and remote display panel.
After browsing the site and the Internet, I have not found a resolution for this; nor another post that mentions this problem.
It could be the USB-RS232 DB9 adapter I'm using; but if it starts the update, I'm not sure how.
Any help or suggestions are appreciated. I sent a message to Signature Solar for support but will have to wait until next week for a response.
Thanks very much!
