A WireBox is a plastic cover that attaches to the bottom of the MPPT controller. It covers the electrical terminals and wire ends, providing an extra level of safety by preventing accidental contact with live wires and making the installation look cleaner. They are available in sizes (S, M, L, XL) to match specific controller models. The wirebox becomes more and more necessary as the panel voltage gets higher because an electric shock from a solar panel is every bit as uncomfortable as an electric shock from any other source.
