Review on 100A Inline Circuit Breaker Reset Fuse, Manual Reset Fuse Holder for Car Audio, Stereo Switch and Solar Inverter System - 2 Pack, 12V-24V DC by Fredrick Edwards

Not suitable for solar. It adds line resistance and heats up. Because of this, performance fluctuates and drops. I've had a set of these that I've been using for about a year and when the sun comes out and my panels are putting out 400 watts the output drops every 30 seconds and then back down to 400 watts. I blamed my charge controller. I blamed my wiring. I even vinyl my panels. Then last week one of those switches started tripping and I replaced it with a double pole circuit breaker for about the same price. Problem solved! Check out my performance chart before and after replacing the breaker. I get an extra kilowatt hour per day without shutting down.
