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.

Perfect replacement
Easy to install and a perfect replacement for my solar combiner box. I would recommend the use of ferrules on the wires if you are using stranded wire to get a good permanent connection.
