HI i have two victron 250/100 tr mppt's. i recently did a firmware update to version 1,47 and one of the mppts are ramping the solar wattage up and back down again but when you test on the fuses the voltage and amperage stays constant.
is there a way to roll back a software to one version prior and reload the new version? because the MPPT was working fine before the upgrade.
your help is much appreciated
