It came from jakiper support last night by emailEdit: also just to confirm, that firmware came from voltronic?
Edit: I'm not sure whom they refer as OEM voltronic or someone else.

At least for the panel I don't think up/downgrade matters since it erases whatever is on there first. I think there's definitely a possibility that it won't let you downgrade the main unit firmware. That was kind of my thought as well with how it didn't change at all. But I think that main unit firmware won't matter much for the communication issues. I think that's primarily handled in the LCD box/firmware.Update: @fanchazstic, I wonder if downgrade isn't possible here? Is main unit latest f\w available? So you can upgrade your main f/w then LCD
I was updating the MCU firmware not DSP. The instructions PDF states to click the Update MCU button. I actually tried clicking the Update DSP button one time but it gave an error about the hex not being found.@fanchazstic Could you confirm you were updating DSP with the 112.19 firmware? I have carefully re-read chat with jakiper and now a bit confused - they said it's MCU f/w.

I haven’t made much progress but that is because I had to travel for work. Will try to circle back to this soon. I did get a phone number for them if you would like that@fanchazstic @Scotts954 please send me your order numbers by PM as soon as possible so I can express-ship something to you.
@PlaneBatteries I know who you are so I've got stuff going in the mail today.
When you three get the part, test it and let me know if there is any changes.
I also have the firmware files for the inverter successfully running in my shop that we can try, if the new part doesn't work.
I just tried this and no change.To those who have SOK battery and their Inverter Protocol doesn't show the current one in the software, I suggest doing this one:
In PBMS Tools 2.5 folder, go to:
Config/XML/..
Rename InverterList.xml to InverterList.bak (for backup, or you could just copy paste for backup purposes)
Then,
Rename InverterList_default.xml to InverterList.xml
Then restart PBMS Tools 2.5.
Then re-do the video tutorial on how to change Inverter Protocol to Pylon RS485.
Disclaimer: DO AT YOUR OWN RISK. (though I believe there is no fireworks in this suggestion)
Didn't work for my jakipers pro eitherI just tried this and no change.
Glad you fixed your inverter as well as the communication issue!!! Now I'll definitely give it a try too. Actually I was itching to do so anywaysI can now report that I have working communication between the batteries and the inverter.
Awesome let me know what happens! Just keep in mind if the flash fails you may have to give it some airflow. Good luck!Glad you fixed your inverter as well as the communication issue!!! Now I'll definitely give it a try too. Actually I was itching to do so anyways
Congratulation!!!
I was finally able for flash both of my units. Faced similar (same?) issues as @fanchazstic. Long story short - most likely you won't kill your inverter in any case. All you need is a good airflow to the heat spot on the PCB. I took mine apart (even removed the display it's not needed while flashing) and used an air compressor to cool it down during whole process, about 11 minutes. That also fixed the issue with my jakiper batteries so no surprises here.Awesome let me know what happens! Just keep in mind if the flash fails you may have to give it some airflow. Good luck!
The one thing that I am a bit confused by is why does a firmware update on this inverter require this much work? I imagine that for 95% of owners this is going to be too risky or technical.
Is it because there is no firmware loading option in the pc software or inverter firmware?
I am just wondering if regular customers need to wait on a loader or how do they get there’s updated?
Respectfully, there's no way for us to verify any of that...
I really don't know how you would expect us to fix this, given what happened.
Let me see if I can translate it based on my time working with Chinese companies.I explained to MPP Solar support in an email the whole situation and their response was, well, I'll let you read it.
Translation, we got some Firmware but the managers do not care about the issue so we are not allowed to spend any of our time testing it. Plus we cannot get our hands on a Rack mount battery.Respectfully, there's no way for us to verify any of that...
We sell Inverters, is your Inverter Inverting? If so why are you bothering us about battery monitoring.I really don't know how you would expect us to fix this, given what happened.
This reminds me of the late 90s and Early 2000s when they had not yet come up with flashing circuitry that first loaded the whole Firmware file into non volatile memory then did a checksum and header test before actually overwriting the original firmware. In the old days if something glitched during an update the unit was bricked. I remember sometimes getting lucky and finding a JTAG port and being able to get the unit going again through that.Unfortunately I can't find a facepalm emote....
So yeah don't expect any kind of support from MPP Solar on these issues. Don't flash that firmware if you aren't comfortable with the risk. They will absolutely leave you out to dry. They didn't even acknowledge the issues. *facepalm* *facepalm* *facepalm*
