The product works well
This product works great. Please ensure you are using ferrules to crimp the end of the copper stranded wires before making the connection, or crip tight with a copper tube end, this will in most case prevent overheating and allow for better flow current. Also if you are using a inverter with built in charge controller is best to use a non polorized switch. This breaker is performs best in my opinion where the battery , inverter and solar controller are seperate devices.

Set it in line and forget it.
I have 3, 6 string solar panels run through to inverter. great for maintenance shut off, or when I occasionally need to feed batteries from a gas generator. Good product.
