The proper wire from the solar panels to the controller and the controller to the batteries is important to minimize voltage drop and thus obtain maximum performance from your solar panel. Our wire is made for the marine environment and will provide optimal power throughput with minimal voltage drop. We will install MC4 connectors on the wire so no special tools will be required for installation.
