July 28, 20232 yr Good Day Folks. Where can one get firmware for the RCT Axpert VM2 Premium Inverters? Is there any folks on here that recently bought and updated and wouldn't mind advising? Thanks
July 28, 20232 yr As a point of interest, what version does it come with? This seems to be a very recent model. Edit: It seems to be equivalent to the MPPSolar PIP-GEW series (3024 and 5048). Edited July 28, 20232 yr by Coulomb
September 17, 20232 yr Author Hi @Coulomb. sorry for the late reply attached is the CPU version Edited September 17, 20232 yr by Jacques1982
September 17, 20232 yr attached is the CPU version The 43.xx firmwares are a jumble, some VM II older, some VM II newer/premium, some VM III, even a small Max (3.6 kW dual MPPT). I have not seen anything that would match your model, sorry.

The one above may be for the "premium" (refresh?) VM II model. Both 43.05 firmwares are only for 1200 W 12 V or 2500 W 24 V models. The older 43.05 supports both the QGMN command (returning 029, for VM II non-export), and QMN command (returning VMIII-2500 or VMIII-1200). The newer one above only has the QMN command, also returning VMIII-nnnn. It looks like they are trying to unify the VM2, VM3, and VM4 firmwares, at least to a degree. @Bassemubid, thanks for sharing the firmware update.
