So I followed every instruction available to connect my classic 150. The instruction manual was worse than some that came with bad purchases that came on the slow boat from china... But I talked to the "experts" at the hotline, looked at the videos, and posted for additional info... When I hooked it up to a 4 deep cycle batteries in parallel (12 volt) the display was a few words on top and a word or two on the bottom and then garbled dots and dashes across most of the display. I tried several factory resets. I think this is going to have to go back to amazon. very disappointed with product, manual, customer service and videos. Anyone have advice on a better product? Maybe from china would be better. I've put thousands of dollars into my project and need a charge controller that works.
