Good work on that clone post coulomb.

I have 8 X 16mm (2 for positive and 2 for negative on each inverter and only 1.5 meters long)

The voltage is fine until I boil the kettle (around 50a) and I get around 4/5v drop across the pack. Probably says more about the batteries. They were sold as deep cycle but have since found there dual purpose so probably not great choice for solar.

It may have been the control board I read about. Is that the one that holds the firmware CPUs etc?
The control board (plugs into the main board on one side) does contain the main digital signals processor (DSP), which contains the firmware, and a lot of other stuff including the EEPROM where settings are stored, and various op-amps and buffers. I doubt you'll be able to obtain a genuine control board, and even if you could, it might have slightly different pinouts, and might not even fit mechanically.
I'll see if I can find a serial number online and go direct.

Might be worth it just for testing purposes etc

Thanks again coulomb

Hello All,

Today I've tried to update the firmware but I get always in the ReflashTool "Can not open serial port" I have tried different USB to RS232 Adapter and different COM ports.

FTDI driver version 2.12.28.0
Prolific PL-2303TA chip and driver version 3.2.0.0 and 3.6.81.357
OS: Windows 10 Pro 64Bit

The Connection to Watch Power via USB to RS232 works without any problems either with the FTDI or Prolific.

Did somebody updated the firmware using one of the mentioned USB to RS232 adapter with Windows 10 Pro 64Bit ?

Thanks and have a nice day,

Stefan

Have you made sure watch power is definitely closed and the com port is open.

For what it's worth, mine (which has done many firmware updates) is a PL2303 RA and the driver is 3.8.12.0. Windows 10 home, 64 bit.
It looks like your Prolific driver could do with updating. I found Win_Driver_Prolific_3_2_0_0.exe in my downloads folder; that sounds like the same executable that you found.
The Connection to Watch Power via USB to RS232 works without any problems either with the FTDI or Prolific.
That's good sign, though I note that firmware updating happens at 9600 bps, but WatchPower and all other commands operate at 2400 bps. It's very unlikely to make a difference.

As already mentioned by jdavies1994, make sure you exit WatchPower via the tray executable, not the File/Exit menu:

Hi All,

I have tried now 4 different Laptop with different Windows 10 version and german and english OS version and still not possible to update the Firmware.
WatchPower communication via USB to Serial works without any issus on all OS.
When I try to update the Firmware I can see the LED on the USB to Serial adapter is flashing 3-4x but then it stops and create the already mention messages, ReflashTool "Can not open serial port"
WatchPower was deinstalled and I disabled on 2 Laptops which used "IPMI Serial over LAN (SOL) which used COM1" in the BIOS / UEFI and deleted all installed unused driver version.

I guess it's the Inverter Type or maybe it's a Clone, can somebody let me know if this PCB is used in other Inverters and if the Firmware update works on them.

Just tried it now with Windows XP, it's the same... so I guess now there are just two options.
1. Both USB to Serial adapter are not usable with the update software even when WatchPower works.
2. Firmware update is not possible with the Steca PLI 5000-48

Hello everyone,
i'm bored with a clone that cannot be upgraded, ...and i've just received 2 others units that cannot be upgraded too, even if the seller sells them for Voltronic models (it will be easy to return them).

Sorry if this is not the right thread but do you think that this one is a REAL voltronic, the seller claim to be an officiel MPPS Solar distributor but ... i don't trust anyone anymore :D

PIP-5048MS 1.0PF 64v, as far as i've read the topic, is eligible to the super/giga firmware ? ;)
Thanks for any info.

I bought mine from maximum solar on Ebay on January 2015. Still works. It is genuine, not a clone.

It certainly looks genuine to me, and I hope you don't mind but I've used your sticker as an example of a presumed genuine model with a custom sticker, in the Do I Own a Clone? post. [ Edit: your serial communications board looks identical to the 2017 model in this post. ]
The Current installed Firmware is 72.10
Are you totally sure it's 72.10, not perhaps 74.10? I say this because there doesn't seem to be any indication on the label that this is a 64 V model. If it was a non-64 V model (max 58.4 V charging), then I'd expect exactly this behaviour not being able to update, but I'd also expect to to come with main firmware version 74.XX. (But I note that this page presumably describing the same model as yours, lists the maximum battery voltage as 66 V).

The other thing is that you need to update to patched firmware version 72.20e (or factory firmware version 72.20), not 72.70c (which sounds like it would be compatible and more recent, but is neither), or 73.00e (sounds more recent, but isn't). Again, attempting to update to either of these two will probably result in firmware update failures exactly like the kind you are seeing.

That seems to be the French version of the MPP Solar Ebay page, and the seller's name (maximum_solar) is the same one I bought my genuine machine from over three years ago. MPP Solar are definitely a genuine reseller; being based in Taiwan, they seem to have good contact with the manufacturer (Voltronic Power does its R&D in Taiwan but manufactures in China).

So your machine should definitely be able to be updated. Please check all the usual problems.

It's eligible for patched firmware version 72.20e and later. Note that the firmware is merely patched; 99.9% of the code is factory original, so I don't think you should expect "giga firmware" improvements.

Hi Coulomb,

The Steca PLI 5000-48 was sold with Firmware 72.10 and everywhere it's mentioned it's 48V, however the max value for the Batterie listed in Menue 13 is 64V.
To make a looong story short,... I have successfully updated 72.10 ---> 72.20e

The next one who will update a Steca PLI 5000-48 will now find this information :-)

The Hardware and Software I have used:

Inverter: Steca PLI 5000-48
Inverter Firmware: 72.10 --> updated to 72.20e
Value Menu 13: max 64V
PC: Lenovo T430
OS: Windows 10 Pro 64 bit
OS Version: 10.0.17763 Build 17763
USB to Serial adapter: Chipset PL-2303 XA/HXA
Driver version: 3.2.0.0

Many many thanks for your time and help to find at the end the solution, great work I appreciate it.

Best Regards, Stefan

Sorry, the only solution is to talk to your supplier, to see if s/he will replace your clone with a genuine model. Some suppliers seem to be genuinely caught off guard by the clones, themselves believing the products to be genuine. A few other clone owners have had success with this. Good luck.

Hi everyone,
I've been following this thread for a while and only today actually joined the forum.

I'm based in Joburg South Africa and own a (rather unusual I guess) Axpert 4000va / 4000W Pf 1 Voltronics (looks authentic) running 54.10 firmware sold to me by Full Circle Solar that recently blew up (leading me to this forum). Fortunately I was able to repair it and in the process upgrade it, physically, by populating the 4 empty mosfets (Q19,Q24,Q38,Q40) that were not present while replacing the blown ones that were actually there. I figured at worst they would help share the load if nothing else. I also had to replace the IGBT's Q27,Q28,Q29,Q30 and as well as Q31 and D13 and the capacitors mentioned on this forum. Anyway it is thankfully working again.

My questions are as follows:

1. I've noticed since re-commissioning the inverter that U2 (SCC firmware version which is 4.12) in the LCD menu only shows up if the solar panels are actually producing power, it is absent and does not report if I scroll through the menu in the evenings. Is this normal, I never took note before?

2. Does anyone here have any experience with these units as I would desperately like to use your patched firmware and believe the hardware should be up to the task if I could load 5Kva firmware on to it. Any suggestions?

3. Is there any way to download the current firmware on the unit for re loading should none of the patched firmware work?

Many thanks in advance for any assistance,
Luke.

Yes. That's perfectly normal.

I assume this is an Axpert MKS 4K. I have no experience of them. There is a small chance that 72.70 or 73.00 based firmware might work. More likely it will brick your inverter, given that your existing firmware (54.10) is not something we've ever seen on an MKS 5K.
3. Is there any way to download the current firmware on the unit for re loading should none of the patched firmware work?
No. There's no way for mere mortals to extract the firmware. You need special equipment and knowledge, and even then it may not be possible. Sorry.

Thanks for the detailed reply Weber.

It is indeed a MKS 4K-48 as you assumed. I guess I'll just have to live with the buggy, limited capability factory firmware for now as I can't afford to replace the unit should I brick it by experimenting with your patched firmware with no way to reload the original version if I don't come right, very jealous of you lucky guys that have the use of the patched firmware and all the wonderful features that come with it.
Maybe one day when I have more money to throw at it I'll give it a bash (brick or not) and let you know what happens.

Regards.

Hello everybody,

First of all Thank You for this thread and your work on firmware.

I have 2x Axpert MKS-4k it is MPP PIP-4048MS, one of them was in basement where was fire last year, I did clean UP, everything looks OK. Afected by high oxidation is only alumina parts like heatsinks. Tin, coat, plastic parts looks OK. Mainboard of inverter works OK. Inverter worked in first few minutes of fire, but without SCC, it was in night!, fans circulates smoke through inverter...

I have problem with SCC (I think I have newer version of SCC). It detects PV voltage, Power UP mainboard through CN2 (2-pin cable from SCC to Main), but no comunication over CN4 (4-pin cable). It looks that comunication from Main-CPU to SCC-CPU going through optocouplers U6, U7, U4 (they works OK), but no answer from SCC-CPU U5 to Main-CPU. Over LCD or USB/Serial no SCC visible, no SCC firmware version, no SCC_Voltage, no PV_Voltage. Do not consume any current (somethink like 7 mA/110 V is there, it looks like voltage deviders)

Do you have some suggestion? Do you have more parts of Schema? Before I'll remove most of water proof coat, I want to try everything possible. What type of CPU is U5?

Relays RY1 and RY2 should switch on before SCC-CPU comunicate or ofter? is BAT+ - BAT- voltage necesary for testing out of inverter? Could I try to comunicate with SCC-CPU from computer?

What is Pin placement on CN1? (ICSP??)

I have no idea what should be wrong, maybe some conductive soot between some wires which are not coated. There is only few uncoated wires... Coating looks really good.

Thank you for any suggestion.

You seem to have gone about as far as you can go. The processor is some type of Freescale 8-bit HCS08 microcontroller, but you'll need the bootstrap loader in there in order to be able to load the main firmware. I don't know of anyone with the know-how to do that.
Relays RY1 and RY2 should switch on before SCC-CPU comunicate or ofter?
No, I'd expect those to stay off till the handshaking is complete, and it's ready to actually charge the battery.
is BAT+ - BAT- voltage necesary for testing out of inverter?
For the inverter, yes. For the Solar Charge Controller, it will probably at least do something without a battery attached, like answer the commands from the main DSP.
Could I try to comunicate with SCC-CPU from computer?
You could try if you're really keen. You'd have to duplicate our sniffing hardware in this post; for that you'll need some way to activate a phototransistor from the RS-232 port, and connect a phototransistor to the RS232 input. We used Industrial (i.e. plastic) Fibre Optic connectors; you could maybe use something else, but make sure it's isolated. You could attempt to replicate the dialogue that we captured in that post. You'll have to figure out what the graphics characters are for the CRC characters. It's the same CRC as used for commands; see the index for details. It seems a lot of work.

I think your best bet is to try and purchase a replacement SCC board from your supplier. Spare boards might even be available from Ebay. Sorry, I can't find a link now, and don't recall where I saw spare boards.

Hi, every one =)
Greets from Finland.

I have two PIP-4048MS units at parallel at the moment. Those are worked nicely since 27.4.2017. There is FW 73.00 if I remember right.
My new plans was to upgrade my system to 3-phase version. After that I can feed my whole house thru solar system.
Well, I cannot find anymore that same version, so I decide to buy totally new ones. Maybe I make a mistake...
I contact directly to MPP Solar and ask if they have that old one at least one left, well no.
Then I ask if they can recommend some to me and they say that PIP-5048MK is newest and would be longer on the market, so if I need one (or more) more later, it is better chance to get those...

Well, I try search if someone have experiences with that new MK series, but there is only two messages with 5048MK key words...
So, maybe I must start telling experiences after I got those. Maybe that happen next week.

Of course, if someone have these, it would be nice to hear how all going =).

There is at least manual link of that MK series http://www.mppsolar.com/manual/PIP-MK%2 ... 181106.pdf

Welcome to the forum.

Paralleling old and new machines is quite tricky. The only success that I know of is 72.70 on the old, and 74.10 (or later) on the new. That means you can't run patched firmware, and you can't have the 64 V option.
Well, I cannot find anymore that same version, so I decide to buy totally new ones.
That seems a bit drastic. But if you do, I'd suggest getting 64 V models, if you want the option of running patched firmware.
Maybe I make a mistake...

I'm sure that there are plenty of 5048 models out there. Perhaps search for the Axpert MKS 5K-48 (not the MKS II), which is a more common name for the same thing.
