I am happy I went with 48v. I'm currently using the Victron IP22 to charge a small 75AH AGM battery for the 12v side. It works well, and the efficiency isn't terrible, but its definitely not ideal. The 48v made everything else so much easier to work with, from wire sizes, tools, etc. Hell I wouldn't be against going higher to 60 or 72v if the equipment was available.
