I have a Quattro 5000 in ESS, CCGX with 2 100/30 mppt controllers and a bmv managing a 24v lithium system.
I’ve read the dvcc documentation several times and am still confused :)
Should I or should I not use DVCC and does it actually buy me anything (in my config)?
My batteries have their own BMS, and their parameters are working fine on the Quattro.
I read a note in the docs that says not having dvcc enabled can cause issues with reduced PV output, with near-full batteries and the “keep batteries charged” ESS profile
Reading the docs, dvcc enabled in a “normal battery” (non-intelligent) configuration defers battery managment profile to the inverter
And if enabled, the SVS (shared voltage sense) can be turned on (which sounds like a good thing).
I am not using a charge control limit
Is there any point to my having dvcc on? (Noting above mentioned issue with ‘keep batteries full’)
Do I gain any benefit from the way I have it configured?
Is there any harm in keeping it enabled (the dvcc text on screen on the gx sounds kinda ominous and foreboding :) )
As always, thanks for any help or advice
