In my boat I have a Venus GX, an MPPT 75/15, a Multiplus 1600/70/16, a BMV 712 hooked up to a 600Ah Winston LFP bank controlled by a REC BMS (not the Victron compatible version). To the MPPT I have connected 2x100 W solar panels.
I would like to be able to limit/stop charging by solar when I leave the boat for longer periods, (as I prefer to keep the batteries at a SOC below 70%), and have thus turned on DVCC, Limit Charging and set Max charging current to 0 A. The MPPT reports that it is Networked, Slave and ESS mode, but nevertheless produces 1A of current (BMS Controlled is turned off). If I increase the charge limit it works correctly (1A also yields, 1A, 2A yields to 2A, and so on, up to what the PVs produce). The fact that I can't stop charging completely (i.e. 0A) is a bit annoying, as it would be nice to have full control (which I don't have now). The Multiplus is, BTW, turned off (via the Venus), and is usually not hooked up to shore power. Any views, or intended fixes in a future firmware version?
