Which do I have, MC3 or MC4 Solar Expansion Panel?

Do I have the MC3 or MC4 connectors on my existing RV Solar kit?

A lot of times it is really easy to determine, you just need to have access to the connectors on the existing system. Once you have the connectors visible, you should be able to see the side of the connector for the MC3 or MC4.

An MC4 connector on the end of the solar power cable has locking tabs on the side. These tabs will keep the connector from slipping off. We can get you a set of adapters to allow you to use newer MC4 solar expansion kits on your existing RV. Give Outside Supply a call for more information.
