There are many other controllers, you just need to get a sense for the limitations and make sure you are working within them. Controllers are not that hard to hook up, two connections simply go to the battery, plus and minus. Then the other two go to your panel. I like to put a switch at the panel output, leave it off while you are hooking up the panel side wiring of the controller, then when you are sure everything is connected properly, and you have some kind of battery power indicatioon at the controller, throw on the panel switch and see if it is charging. Remember that a panel is a power source, and connecting it to the controller while it is in the sun is like hooking up a car headlight while the lights are turned on. Another option is to wrap the panel in a blanket and put it in the shade while you are connecting it up. Your panel has a max amp rating, Imax, which will likely be around 5 or 6 amps at that voltage and wattage. Number 4 romex will work for that, as well as medium duty AC extension cord wire, if your run is less than 30 feet or so. Take care Steven, Rudydoo
It depends on the power you need. There should be a controller between the battery and the solar pv panels.
What are you going to power with your 260w solar panels? Tools? They generally use more than 260w. The panels will generate electricity. The problem is that your tools likely don't use DC. And if you're asking here, it's not likely that you have the background to hook everything up correctly. You'd need both batteries and a pretty good sized inverter.
