My motorhome has 400 amp hours of AGM batteries for the house batteries, fed by 400 watts of solar. I also have a standalone 12 volt air conditioning system that uses two 300 amp hour batteries, fed by 600 watts of solar. There are times it would be really nice to move some of the power from the lithium battery bank to the AGM’s. Is there a DC to DC charger that I could connect between the two battery banks that will do what I want? If so, any recommendations on which one that would be?
A little more information— I really don’t want to replace my AGM batteries with lithium, and I have no need for an inverter, so I don’t believe I’m in the market for a MultiPlus.
Look at Victron’s Orion line of products. The Orion XS 12/12-50 or the Orion XS 1400 would be good options. If you haven’t already, I would suggest you contact your closest Victron installer or distributor for more detailed guidance.
Thanks so much! This is the exact guidance I was looking for. After looking at the specs, I really think the XS 12/12-50 is going to work well.
