My inverters was with following specs:
U1 71 50
U2 01 12
U3 00 21
U4 00 00
You must have had PV off, or it was at night, for U4 to be 00.00.
After MCU update
U1 71 50
U2 02 00
U3 88 88
U4 01 10
After FW update
U1 71 80
U2 02 00
U3 00 21 (exept one left to 88 88)
That's back to what it was. It seems that 88.88 is the new display / Bluetooth firmware.
[ Edit: sigh. It seems that 88.88 is an invalid version number; I failed to notice that the U2 version changed from 01.12 to 02.00. Thanks Weber. ]
U4 01 10
So if you look that earlier post WatchPower screen shot, you can notice U1 is main CPU and U4 is secondary CPU.
My understanding is:
U1 is the firmware for the main DSP, as always
U2 is the firmware for the removable display
U3 is the firmware for some sort of co-processor or slave, which may handle Bluetooth to phones. That didn't seem to get changed with this pair of update files.
U4 is the firmware for the Solar Charge Controller. WatchPower is still calling that the "secondary" firmware, from back when there were only two.
[ Edit: Thanks to Weber, I have swapped the descriptions for U2 and U3 from what I originally had above. ]
