If you are installing some solar panels with a MC4 connector, I definitely recommend having this key set around. These are a plastic set of keys that will allow to disconnect the male/female connection once connected. These MC4 connections lock in place to make sure they did not accidentally get disconnected.
If you are like me (human) and make mistakes such as connecting something before it is ready to be connected…you will want to have these around.
Some solar kits probably come with these but I bought everything separately. You can check out out our solar install video here.
