We have a Calex 3000 bidirectional 48-12 converter, max 3000w. Great idea, but it does need a 48v on high side and 12v on low side before it turns on, so it doesn't take the place of a 12v system - you still need to generate 12v somehow! I'm using a small victron Orion to kickstart the voltage.
Hey Matt, thanks for all that. As always on this group, it's nice to hear the opinions of folks who know what they're doing. Nice website by the way! We do have a rather large LifeP04 house bank that's only a year old - 900 amp hours. I had intended to use a Victron MPPT or a DC to DC converter to charge that from the 48v bank and direct all charging sources to the 48v bank. I hadn't thought of a bi-directional DC converter - I'll have to look into that. My next question is, with multiple charge sources - 2 (maybe 3) solar banks with separate MPPT's as well as the generator, what's the best way to control multiple sources charging the batteries at the same time?
