Need firmware Axpert VP2000-24 PWM inverter


Recommended Posts

Hello! I have an Axpert VP2000-24 PWM inverter (MPP clones PIP-2024HSE, AXIOMA ISPWM 2000-24, etc.). After a lightning hit the roof of the house, a bunch of transistors were knocked out, but the worst thing was that the processor firmware was damaged. I had firmware 08.33. I have already researched many forums on the Internet, but did not find a similar firmware. I tried to upload firmware 15.61 and others from AXPERT HS and KS - they do not fit. Proc starts normally and after 5 seconds it turns off. At the same time, it incorrectly shows the battery voltage (12V instead of 24V). Service in my country also could not help me with my problem. Maybe someone already faced such a problem? Share your experience, please.
