We did installation of 8-10 years ago and recently we replaced old lead acid batteries with lithium batteries however the older processors (1958 on a Quattro we did on this past Friday) cannot update to ESS. I had to use Virtual switch to disconnect form grid based on Voltage and disable the charger to prevent grid from charging the battery during grid connection.
My question is, does Victron plan on making an update available to older processors to allow ESS to be installed as this will become a bigger issue as more people need to replace their batteries with Lithium alternatives.
