-AC Units that can operate directly on DC current off of your house batteries give some efficiency gains as you don't need to run them through an inverter, but they are very expensive.
+AC Units that can operate directly on DC current off of your house batteries give some efficiency gains as you don't need to run them through an inverter, but they are very expensive. Higher voltage systems allow you to use much thinner cables for power, which can be a significant cost savings over longer runs.
 **All-in-one roof units** offer a much simpler installation and are usually around $2,500; Dometic has their [[https://www.dometic.com/en-us/outdoor/rv-and-van/rv-air-conditioners/dometic-rtx-2000-262673|RTX 2000]] unit as a good start for most vans. The relative ease of install comes at the expense of taking up quite a bit of roof space (and consequently reducing your available space for solar panels). They're heavy as well, and generally you'll need to reinforce the roof to hold the weight.
