“I upgraded from V2 of the DC-DC charger to V2.2 because of the higher solar input voltage of 32V. I haven't tested V2.2 during a trip yet. I only connected it to make sure it was working properly. If it works the same way as V2, which I previously used, then it's a great piece of equipment. Just plug it in and forget about it. With the V2.2 and its 32V solar input, my larger fold-out panel won't cause it to trip like the V2 model.”
