Can vouch for the above grade construction of these products. If you're thinking of venturing into this value space, this is an excellent opportunity.

This looks like a great deal for doing a few in parallel to run a house through solar. Anyone have any links for how a setup like that would work.?

It's about equal if you need it shipped ($300 extra for the 314AH version brings it to $1800). For the larger one (300lbs), local pickup from Walnut CA gets you the nice $1500 price. With the large one you'll save on not having to use external cables between 3 smaller rack mount units. I wonder how it holds up to the semi-DIY Yixiang 16kWh options. https://www.mobile-solarpower.com...fepo4.html

It won't let me do that... Strange.. That would save 18 bucks but it would still be right at 600 bucks final cost.

The $18.73 "shipping protection" wasn't mandatory for me. It came as a "pop-up" as I was checking out & had an option for "no thanks".
