The 80W Solar Panel is designed to be used in conjunction with the MB iSeries Energizer and MBS Energizer range. The product includes a solar regulator for maximum solar efficiency, a multi-purpose mounting system and all connections required to plug directly into the Energizer and a 12V deep cycle battery. No assembly is required. Once the solar panel is mounted the only additional work required is to connect the supplied leadsets to the Energizer and battery.
