November 2, 2025Nov 2 Good morning. I updated the firmware on my VM IV TWIN 6k inverter, but after the update, I got Error 32 and it stopped working. I've attached screenshots of the pre-update version (U1, 60.10) and the removable screen (U2, 39.17). I need the main firmware update. Thank you.
December 8, 2025Dec 8 Hopefully you are well sorted by now. If not, suitable firmwares are available here:https://powerforum.co.za/topic/29708-collection-of-dsp-axpert-firmware-for-vm-iii-twin-and-vm-iv-twin/The new VM IIIs and VM IVs somehow use the same firmware.
