The enclosure comprises a container having side walls, a bottom wall, an open top, and a dividing wall that divides the inside of the container into first and second compartments, both of which are accessible from the open top. The first compartment is capable of housing at least one 12v battery. The second compartment is capable of housing at least one electrical component other than a battery. The dividing wall has an aperature capable of permitting a wire or other electrical connector to extend therethrough to connect the battery to the electrical component. The enclosure further comprises a lid capable of fitting over and enclosing the open top of the container to provide a water-tight seal therewith. An electrical connection is provided for electrically-connecting electrical components within the container to a renewable energy generator outside the container.
