Updating the Firmware for EG4 6500 Inverters

With the release of the latest firmware from EG4 (79.61), it's supposed to resolve some flickering light issues when you have PV power coming in to the inverters.

When I looked, there really wasn't much inverter update documentation, so I'm going off what I found in order to update the inverters. Never done it before, so let's see how it goes together!

With this specific update, you have to run 2 programs to update the firmware.

Hopefully it helps someone out. Ended up having to re-flash inverter one 3 different times because the screen recording software wasn't working well on the Windows 8 computer...gotta love technology...!
