Solar DC Isolator Switch 1000V/32A PV DC Battery Disconnect Switch for use in Inverters, Combiner Boxes and Battery Energy Storage Systems

I've been using this switch daily for about 2 months now. Volts are between 460 and 540, and amps from 2-8. I've not heard any sounds of arcing, or seen anything that would make me think the switch wasn't positively connecting or disconnecting the power. The switch "feel" has stayed consistent throughout.Since I am only switching two poles, I'm using this with the included jumpers installed at the bottom. My DC+ and DC- feed wires come into the two outside screws at the top and the load wires connect to the two center screws at the top. This allows all 4 poles of the switch to be used for switching my two wires. DC likes to arc when it's switched, and by using 4 poles instead of two you effectively double the switch gap to kill the arc when connecting and disconnecting.I would have liked the handle to be longer on this switch, but it does work as it is. Everything else is great.
