VP5K_VM5K_MAIN_Reflash 20.13 20.14.zip 20.14

This is main (U1) firmware for the Axpert VM II, and probably also the PWM versions thereof (probably called an Axpert VP II or just Axpert VP 3K-24 or similar). This file contains both version 20.13 (2018) and 20.14 (November 2022). It supports 5 kVA, 3 kVA and 1.5 kVA models, all PF0.8 or PF1 (selected by resistors at start-up), except that the 1.5 kVA model is PF0.8 only (1200 W). I can't recall where I found this firmware. Do not use with any other model.

Use at your own risk.
