Bought this to keep batteries on my sailboat topped up for the automatic bilge pump. I have to travel and leave my boat alone for a month at a time. Seems well made, good design.
Manufacturer sells this as a charger/maintainer for batteries. Measured voltage output in direct sunlight is too high to connect directly to a battery - as much as 19VDC, requires a controller/transformer to charge properly. Not a big deal, as a controller is not expensive, but didn't think I would need one when I bought the solar panel.
