So i have an older mppt running firmware 1.07 victronconnect won't see it, (ve.direct mk3 to usb cable) but via serial connect i get a response:
Checksum manf Victron Energy prod MPPT 12..24V/15A ser# HQ1302XWRZ9 ver# 1.07
How can i update it there must be away to directly upload via serial or hell maybe even via rom reader directly on the chip. these device's used to be updated via older software what that is i have no clue but without access i can't configure it so its rather important i can update it or atleast configure,
