Why is customer service so hard for so many Chinese (including Taiwanese) companies?
Yes indeed!

I have 12+ 4048MS out there. One system is 12kW and another 24kW. The freezing is a massive nuisance as it transfers the entire load to the batteries during the freeze - this is some 180A to 240A - not funny when you have 6 of these inverters on a single 3-phase estate.

Thank goodness I have a 600Ah battery bank on this system.

But that's not the point - is it? I have sent MPP charts, details, times, circumstances and well - they just haven't replied. These inverters will destroy my reputation

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. ]

[edit] I remove links because of (and if I read right, there is at least two hardware versions. I do not know what version mine is. My inverters have label with 11/2018.
...
[/edit]
My guess is that your machine, from November 2018, is one of the oldest [ edit: actually, the first seem to be from August 2018], and this seems to be the very latest firmware (the latest we've heard of before this is 71.70). So I'd guess it would be safe to try.

I can probably dig out the URL from my browser history, if any users are desperate to try out this new firmware, and have a similarly aged machine. PM me with a photo of your machine's barcode sticker if interested.

Ok =)

Ofcourse I have also those files, so PM me also could work...

After update, I can read all inverters through one.
@Suorama,
can you give a few details on how you updated?
  • Did you use the serial port or the USB port?
  • Did you have to press any buttons to get the inverter into update mode?
  • Was there anything else tricky?
Other users are getting comms errors attempting the update.

No, there wasn't any tricky.

I must use serial. I do not have real serial port with my computer, so I use USB to serial adapter. That adapter is good one and works like real serial port.
That why I must use serial was, because that update program, what came with 7z pac, works only with serial.
When I update MCU I just start program "Remote Panel_Reflashtool.exe" in the computer and in the program I first select right serial port and then I push "Update MCU" to start update. Then that panel go to black and it took ~9min to erase and write per inverter (or maybe that was 6min).
When I update FW I just start program "AxpertKINGReflash.exe" in the computer and in program I first select right serial port and then I push "Update" button to start update. Then whole system "goes down" aka stop feeding my home and not charge or take any power from anywhere. Then panel shows to me:
UPDATE
YES?
I'm not sure if I must push the button next to YES word, so I push it.
Anyways, there wasn't any problems. That phase took also appr. 10 min per inverter.

I do all MCU updates first and then FW updates. (I have three inverters and 3phase system)

edit:
And ofcourse, first of all, I un(7)zip both packets to they own folders and start programs from those folders. With MCU I left all other setting as is (Baudrate 19200), only Serial was that what I choose.

7-Zip is a free program for zipping and unzipping archives; it is free to download. I have it installed, so I don't know if Windows knows what to do with a .7z file if it's not installed. It is known that WinRAR won't extract these files properly. WinZip will do it, but the free version expires in 30 days. (Thanks, Jaco.)

Those needing more details, like which cables and USB to serial adapters to use, may find the PIP-5048MS firmware upload instructions helpful, but of course they won't apply perfectly to the PIP-5048MK.

Jaco,

Any luck with the 71.70 firmware?
Sadly no

Im only 71.70 and experienced a pv freeze today.

I'm not sure what you guys mean with that PV freeze. What I noticed, my system seems to drop down PV when major change happen. Example if my load exeed my PV power and inverter change its working method to utility. But if there is example 1kW solar energy and load bite 5kW and my weak battery give only few minutes that missing 4kW then inverter change to utility. I can see then that PV power goes down, but there is still informed that 112V of panel voltage and after second that 4kW power change to 3kW and after few seconds I can see when PV power start rise back ro 1000W.
But PV power rise momentarily higher than that 1000W. I think that why I can see sometimes over two times higher power from my PV than it really is.
I can also see reasonable voltage at mornings and evenings from PV but system inform 0W from PV (4048MS shows usually ~160W those moments with same panels). Same time I can see how load is ~100W and battery is not drained but charge sone times a bit.
So, next complain what I do to the MPPSolar support might be that behavior.
