Using ESS/DVCC over 2 years, I am still missing a simple feature, controlling charging of MP2 and MPTT independently.
During most time of the year, the MPPT has enough power to charge the battery by its own (I do not need the AC couppled PV for charging), but it is not possible do configure a CCL which only controls the charge power of the MPPT, MP2 is always charging in addition, or the MPPTs are rampted down an the MP2 is charging only.
One workaround is, do set the CCL to 0A and enable feed in of DC surplus within ESS, but in that case the MPPTs does not stick to the CVL (because it can go 0,4V over the CVL). In combination with a feed in limit, that is also not a good solution.
So I am still missing a possibility to either configure a CCL for MP2 and MPTT seperatly or/and a CVL which controls the MPPT without any +0,4V feed in ( like the workaround but a the MPPT keeps within the limit of the configured CVL ).
Hey Victron, can you do that?
