I bought 2 solar trailers at an auction and decided to give a review on them. One I paid 5500 for it and the other one I paid 7500 for it. The solar trailers are really well put together with 2 volt lead acid batteries, and is a 48 volt system with the 2 volt batteries placed together in series. The trailers each have 10 solar panels equipped with a charge controller, combiner box, two 6000 watt inverters, ac panel box, outlets and 50 amp plugs on the side for plugging in a welder, rv, or your home. Here are a few links to some good solar equipment that I would recommend.
