I have a small RV so very limited space. I have a Xantrex 3000 XC Pro Inverter/Charger because I don't have enough space for a Victron Inverter. I also have solar and a Victron 50 amp MPPT controller (also Victron Venus and BMV).
I am considering 2-3 Victron 200 ah batteries because they are also quite small. And a Smart BMS 12/200.
I would be connecting the alternator to the alternator terminal (I can get rid of my DC-DC charger). The solar and load I can connect to the System managed bolt.
That leaves the Xantrex. Inrush current on startup is MUCH less than Victron Inverter but still way more than the BMS 12/200 will handle, so I am proposing to wire the Xantrex directly to the batteries and then use the BMS charge/load disable terminals so it can signal the Xantrex when to disconnect loads or charger if needed,
Is that a viable solution? Has anyone done this? It bothers me a little because if the Xantrex and Victron miss-communicate a cutoff situation I could fry $6,000 of batteries.
But it should work fine I believe.
