I would pull them out and make sure your cables are the right polarity, and that you have the right connectors and adapters for whatever you plan to power.
Would this be a good system to keep the starter battery charged on my riding mower? I keep it stored in a lean to shed and wild like to mount a panel on the wall and have it feed a trickle charger to keep the mower ready to start.
best video ive seen today, wow. love the price, was looking for a couple panels for my garage roof to use with my dr. prepare battery and 700watt renogy inverter. does the charge controller that comes with it show the incoming wattage?
Ive seen reviews that this panel only outputs about 50W, not the advertized 100W and that they are impossible to get in touch with for warranty service. Any thoughts on those two issues?
