Some comments about this we saw on the web:
* /u/RounderKatt on /r/BurningMan I have a 100w renology panel and this charge controller. They fed into a 100AH deep cycle battery from costco and kept my swamp cooler, cell phone charger, and LED lighting running all week last year.You need to use a deep cycle or marine battery as they are designed to be run down lower and more often. As for wire, the panel has a short cable so I bought an extension and wired that directly to the controller. I believe I used 12 gauge solid core wire for the connection from the controller to the battery. all ,my stuff connects straight to the battery, however I want to add a terminal bank to make it easier.
——* /u/bemerritt on /r/BurningMan at first i used this controller ad it worked very well for me:
but i wanted to upgrade to an mppt controller instead of pwm (plenty of articles out there explaining the difference, but basically mppt can give you ~30% more charge wit hteh same setup). I also was using agm batteries and wanted that setting on my controller. so i ended up with this:
