Currently I'm designing a new setup for my sailing yacht, switching from VRLA to Victron Smart LiFePO4.
System will look like this: 4x100Ah Victron Smart LiFePO4, Multiplus 12/3000, VE.Bus BMS, BMV, Cerbo GX and BP 12/220. See also attached system proposal.
There seem to be several options to control my charger(s) (SmartSolar 150/35 and SmartSolar 75/15 max. 600Wp PV and probably 2x Orion TR 12/30 in parallel, which will replace a Sterling alternator to battery charger, to save batteries in the event of low or high voltage / temperature. Since I want to keep the VE.Direct ports free to connect to the Cerbo, the option of using the VE.Direct non-inverting cable is not available.
Another option could be in using a smart battery protect and let the VE.Bus BMS do the job by "cutting" the line. And there are Cyrix with different options. Not sure if they are able to shut off the chargers in the event of LV or HV. And I'm probably not up to date with what Victron Connect or VE.Smart Network can do. Devs are very active and there are so many changes within the last couple of months.
So I'm asking for recommendations. Which way is the best to control my MPPT's and the Orion's?
