Hey ya'll, my replacement Samlex arrived today. I read the manual carefully but what it suggests is what I had already done before when my first one failed on me. I have a 100 watt fuse on the positive cable, as suggested, and the charge controller only spikes to 16v. The Samlex can fail at 16.5 volts. I know this company won't keep sending me inverters so I want to make sure this one is well protected. What can I do?
