smallbms ATC output

Hi, looks like need to add a 'Small bms' to safely charge my two new 100ah Victron LFP batteries. Can I connect the bms output, ATC, to the 'remote' of both my victron MPPT 100/30 solar controller, AND my Victron Orion 24/12 DC/DC controller (24dc alternator)?....cheers

Um, did a bit more research, question still stands but I will need to get a 'V.E.direct inverting cable' for the MPPT controller

@Mike Gillming Depending on the type of Orion (isolated/non isolated) would require a specific "cable" for the Orion.

Got an inverter/inverter/charger?

Thanks mate, Upon further reading, yes the Orion is a 'Tr', so according to the Appendix, "all Tr's" will can be controlled by a single conductor to the remote. And my MPPT requires a special cable. I suppose the real query is controlling two different devices. I've seen were three MPPT's were all linked, so I'll give it a try...thanks again for responding...cheers

Were you successful connecting your single smallBMS ATC to two chargers? I need to connect mine to three: 1) SmarSolar MPPT-50 (via VE.Direct non inverting remote cable) 2) Orion-TR Smart 12/12-30 Isolated DC/DC charger, and 3) a non-Victron AC/DC converter (via Smart Battery Protect). I hope to do so via a 4-pole distribution block, but I've read I might need a SolidSwithch 104 which "boosts" the ATC to handle multiple chargers (among other things).
