So we are looking at an electric power station and solar charging in the $2-3K range. The Jackery 1500 came up on our list, but I don't know about the solar charging and the connections it uses. We'd probably want a 50 foot extension between the solar panels and the unit. Does such a beast exist? It sounds like there is only about a 10 foot cable between the solar panels and the unit itself. Is there an available extension? And if not, is there another unit in its class that does have the ability to extend to 50 feet? I'm pretty ignorant about electric power stations and solar connections. Thanks!
