MPPT Firmware Downgrade

Hello, is it possible to downgrade MPPT firmware to the previously installed version if the new one is suspected of causing issues and a process of elimination is to be used to diagnose the fault?

I’m sure the MPPT’s are a way one pony though, shows an error on attempts to install legacy firmware…..

cheers

Hello, i can only see the one listed below in the pic, which is what I already have installed. It's the A063 version. Not sure where to get the legacy one from. 1667295918010.png
