I wanted to make my little workshop / shed off grid so bought this kit on a Black Friday deal so got 20% off original price. Does it work, yes - pretty damn well. I've actually added another panel and battery to the set up as well. I use it for charging all my tool battery's, bench grinder, running my rabbits airflow / fan system in the summer, internal shed lights and also an external flood light for the garden (Not all at once). Granted I'm an electrician but for those who aren't it is really easy to set up, basically plug and play. You will have to cut some cables to length but basic tools are all that's needed. Only thing I would say to watch out for is that if you intend to by a kit like this and maybe extend it, plan it out as you will need to buy new male/female connectors to accommodate extra panels etc
