June 27, 20241 yr Author Don't worry man, you're good! You can't really return to the exact stock firmware that came with the device, as it is (not possible) to extract it or make a backup of it. However, you can reflash the very same firmware version and it should be all good and no differences. As a general rule, you can always reflash whatever firmware version you like, as long as it is exactly for your device's model. There are no version restrictions when it comes to reflashing a firmware. You can use the search feature in this forum to find other MCU firmware versions. There are a lot of options if anything would go wrong for you, and I guess you'll find the exact version or a very close one at least. Just always make sure you know what you're searching for!

Thank you brother Attach an image to a file 25.12 But there are two buttons to scroll which one to press update mcu or update dsp

You can "go backwards" in firmware revision, as long as the inverter isn't "bricked". Even if it appears to be bricked (unresponsive), it's usually possible to recover. I don't believe that you will have want or need to go back to 25.08, but at least it's a known quantity that you can go back to if needed.

As far as I know, you should never press the bottom button. It looks like they wanted to merge the DSP and MCU reflash tools into one, but they never finished it.

June 27, 20241 yr Author Exactly, you're right on track! I Wish you good luck with this. I understand that it's very confusing at the beginning, but once you do it the first time it becomes an easy task.

June 28, 20241 yr Hi all, I talked to @mhd_murad and he had a problem with MCU firmware 25.12 in saving settings. He can change and save the settings by only using WatchPower, but directly from the display it won't save the changes, so he rolled back to 25.08 Edited June 28, 20241 yr by AMalakani

He can change and save the settings by only using WatchPower, but directly from the display it won't save the changes, so he rolled back to 25.08 Oh, this is not good news Because sometimes we have to change the settings of WashPower for ease of use Especially factory reset Not available on this model And also when entering the public network I adjust the battery charge value to operate AC2 without waiting for the battery voltage to rise, and it is faster through the application than entering the settings from the device To note, I encounter this problem sometimes in version 25.08 and I have to do a factory reset and redefine the Wi-Fi . Has he tried it?

I'm afraid it has become some sort of incompatibility between MCU and DSP firmware, although I think no one can confirm it. Would he like to try and reflash his DSP firmware too? So he reflashes both DSP and MCU to their latest versions. @Coulomb any thoughts?

June 28, 20241 yr Author That's exactly what I expected in my previous post. I hope everything should be fine now.
June 29, 20241 yr On 2024/06/26 at 5:24 AM, Coulomb said: Just that operating at higher temperatures will cause some components like electrolytic capacitors to age faster. Out of the factory, they aren't particularly long life to start with. But if you have to operate it in a living area, then the quietness is important. this is voltronic support reply for temperature @Tarek Yag @Coulomb @AMalakani Dear Mohamad We changed the firmware to reduce the fan speed but internal ventilation and hardware don’t do any change, For surely,the temperature will be higher than before. We had tested it even we reduce the fan speed,the internal components can afford the higher temperature

I'll stick to the 60.89 and I'm going to update the MCU at evening to 25.12

Edit: So the incompatibility seems to be between 60.95 (with the quieter fans) and 25.12, but not 25.08? Maybe reflashing to 25.08 didn't fix the problem anyway, as it was in 60.95?

Quieter fans are introduced in several recent VM III firmware versions as testers mentioned in this thread. @mhd_murad would you please confirm which DSP firmware you had the incompatibility with?

Quieter fans are introduced in several recent VM III firmware I also tested this version (60.95) and it runs nearly perfectly. My DisplayFW is : 25.05 Much quieter fans at low loads and the heatsink temperature has never been above 45°C. At higher loads (>1500W) the temperature drops again because the fan(s) then run faster. The inverter hangs in my basement at around 19°C. Another positive thing about the software version is the fact that the MPP-Tracker no longer gets stuck at low voltage. So far I've had to use a version modified by @Coulomb so that the voltage doesn't get stuck below 100V. Thank you for this Software-Version. Edit:typo Edited July 1, 20241 yr by pintopf
July 1, 20241 yr Author @pintopf Great news! Thanks for your feedback. Any plans to upgrade your display firmware?
July 1, 20241 yr Is there a change log for the firmware versions? Are there Improvements? I control my inverter with an ESP32, which get the data from the VMIII over serial connection and build up a communication via WiFi (MQTT-Protocol) to my home-automatisation with NodeRed. Since I don't miss any functions, I conquered my curiosity and didn't install any new firmware yet. 😉
July 1, 20241 yr Author I've never heard of a firmware change log for Voltronic inverters, though Coulomb is always interested in making version comparisons when needed. Since there are no change logs, improvements are not documented, hence not guaranteed! I salute you for conquering your curiosity! 😂
