MC4 Solar Connector - Price is per MC4 pair simply select the quantity as the number of MC4 pairs you want.

These are the standard connectors used on most solar panels.

TUV certified, brand new, water /weather proof rubber seal that can ensure excellent electrical contact for life time service.
The metal pin is made from high quality machined copper and sealed tip (compare to the cheap sheet metal pin) that can ensure excellent electrical contact for life time service.
Build in press tabs for easy disconnect, no tool is needed. 25A max load.
Wires should be crimped or soldered into the pins and care should be taken to get the correct pin into the correct connector. Once the pin is pushed into the connector it is difficult to remove without the correct tooling.
