    I would use NSI Polaris connectors then.

    You can use a split bolt connector, see picture. Any connector must be rated CU/AL or for both copper and aluminum.

    Aluminum and copper wire cannot touch each other. Notice in the picture there is a wedge, one wire on one side of the wedge, and the other wire on the other side of the wedge, so the wedge is between the wires.

    After wrench tightening the connector, it needs to be wrapped with rubber tape and electrical tape.

    A better method for a DIY'er would be an pre-insulated connector.
