    Well...it's a lot for batteries and solar, but it sure ain't much for a small generator (or decent alternator) and you could probably get by with running one full (usually 40 minute) cycle per day if...

    Agree with Vortec.

    On average, most people see maybe 10%-15% increase in watts harvested by using MPPT. Using MPPT for battery charging (different than feeding a grid-tie setup) the most benefit...

    Yes MPPT is better, but the general consensus among solar engineers is that MPPT is generally not worth the extra cost for a solar rig of less than 200w size.

    It'll work just fine. The only possible problem is the output limit - it can charge at up to 30a for up to 30 minutes, then drops back to a max of 20a after that. Depending on the size of your aux...

    If you didn't have a battery connected to load down the panels when you tested them, then 12v ain't nearly enough.

    A proper "12v nominal" solar setup should be capable of putting out at least 15v...
