July 17, 20206 yr Hello all. Can you advise what your firmware version is, if you have an Axpert King 3K. My current version is 51.50 with a display version of 1.10 I am looking to see if anyone has a newer version and if by any chance, there is a download link for the updated version

My one unit is a Sept 2018 (Full Circle Solar) and the other is a Dec 2018 (Mustek) both the the same firmware as mentioned above. Keep in mind that these are both 3K unit and not the 5K which I believe has a different firmware (sadly). Any insight with regards to updating would be greatly appreciated

I have a theory that the remote display firmware is common between the 3 kW and 5 kW models, though that might not have been the case before say remote display firmware version 02.00. There is code in the display firmware checking for 48 V or 24 V, and adjusting battery voltage related settings options as appropriate. But it also skips all the BMS code if it detects 24 V (3 kW). But as you say, the main DSP firmware is different. Since you're not able to use any of the BMS related features, the main DSP is the important one.

I would be amazing if both units could use the same firmware and simply detect the hardware.. Oh Well. 2 questions... when mention the BMS features, what features are you referring to? I also have a 5K model and have not noticed any difference between their feature sets (besides Pylon support which I put down to old firmware) The reason for me wanting to upgrade firmware, is I just connected the 2 units in parallel and run ICC Monitoring Software but the software does not work with the Parallel cluster. They (ICC) seem to think it is due to the old firmware as on the 5K models there was apparently an update for this.

They way that recent versions of King firmware can talk directly to Pylontech BMS and supposedly do everything automatically: that is now available for several other battery BMSs. The firmware to handle all that is in the remote display firmware (U2), not the main DSP firmware (U1). 8 hours ago, Jay-Dee said: ICC Monitoring Software but the software does not work with the Parallel cluster.

Let me quickly check the revision log... oh, wait... there is no revision log! 😠

Fortunately, I have a Victron BMS 700 for that, so not an issue / deal breaker for me 2 hours ago, Coulomb said: Yes, from memory this was fixed about 71.86. Let me quickly check the revision log... oh, wait... there is no revision log! 😠 So sad but true 😭... The 71.86 is on the 5K units... no one at this point can tell me about firmware for the 3K ones... Tomorrow, I am going to get hold of both manufacturers and ask them if either can provide me with an updated firmware or at least confirm what the most updated version is. Failing that, I will get hold of MPP Solar in the US and try them they rebrand the same model... Hopefully some buttering up will convince them to send me a link / copy Out of interest... Should I fail with the new firmware... 2 questions, if you know 1) with the units setup in parallel... if you make settings changes to the primary unit, do they automatically mirror to the slave? i.e. if I change the inverter mode, SBU parameters etc. 2) If not, with the above... Do you know of any alternatives to ICC Solar that I could try to monitor the cluster? My main concern is if I don't get the cluster monitoring working and the units don't "talk" to each other as per point 1... I am running the Solar based on my BMS which is connected to ICC and Inverter 1.... Some funky #$%^ will happen if one is running off PV and the other is charging Sorry in advance if the concern is premature but I never thought about this until it did not work 😬

I think you have a legitimate reason to request a firmware update. Quote 1) with the units setup in parallel... if you make settings changes to the primary unit, do they automatically mirror to the slave? i.e. if I change the inverter mode, SBU parameters etc. Most settings automatically transfer, but some such as maximum charge current (total for this inverter, and utility charging for this inverter) are separate. You might have more PV on one inverter than the other, for example. The master's firmware automatically adds up the maximum charge current for all the machines (slaves plus itself). Quote 2) If not, with the above... Do you know of any alternatives to ICC Solar that I could try to monitor the cluster? I don't think monitoring software can make up for the firmware problem. My feeling, totally unchecked, is that the problem involves all or mostly the reporting of results, not exchanging of vital data. Quote My main concern is if I don't get the cluster monitoring working and the units don't "talk" to each other as per point 1... I am running the Solar based on my BMS which is connected to ICC and Inverter 1.... Some funky #$%^ will happen if one is running off PV and the other is charging I don't think that this is likely, but that's mainly a guess.
