These MC4 T-Branch connectors are for use with two or more solar panels where you want to connect them in parallel to keep the same voltage and increase the charging amps. If you want to connect three panels together then consider using our Triple branch connectors to save money.
The connectors are high quality ISO rated against water penetration and have double sealing rings to ensure they will stay waterproof for the life of your system. It is not necessary to have a tool to disconnect these connectors but it does help.
We offer an unlimited guarantee on our MC4 branch connectors. If you have any problem we will replace without quibble.
