## Customer Reviews

### ⭐⭐⭐⭐⭐ works great highly recommend
*by R***D on May 4, 2025*

works great looks nice and the quality is amazing seems very durable and its a great value for your money glade i bought it

### ⭐⭐⭐⭐⭐ Perfect replacement
*by J***T on June 3, 2025*

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.

### ⭐⭐⭐⭐⭐ The product works well
*by P***L on April 6, 2025*

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.
