Glad to see Dual Pro on that list. A Dual Pro Sportsman Edition is the one that's been keeping my sump pump batteries happy for the last 5 years or so. They claim that series is "Fully Waterproof". I can't vouch for that since the whole purpose for mine is keeping water _out_ of my basement.
It's 90% of MPP for two 100W panels, on a PWM controller. I used my UT210E clamp-on to adjust them for the maximum current, though some misalignment didn't hurt much.
The high current, heavy cable parts are close to the load, which is the fridge and computer desk. The indoor layout makes sense for a closely watched experimental manual backup system but wouldn't for an automatic daily cycling one. Once I have a better idea of what I need and have space for I may move the batteries and a larger inverter into an outdoor enclosure, or change to AGMs or Lithium.
At this point I hopefully know enough to be able to snap up good deals I may happen onto, like these Home Depot panels.
