I have
these which is a 400 watt kit w/ everything you need all in the box. Fwiw if you order from them they'll accept a "best offer" of 5-10% less. They've been fine so far. The one caveat w/ hooking up solar panels to a charge controller is to follow the instructions and do it in the order they tell you. If you do it in the wrong order you'll fry the controller. I learned this the hard way 20 yrs ago and have come across plenty of people who made the same mistake.
