PVS BLOCK
BAE Secura PVS solar batteries need only low maintenance and are used to store electric energy in medium and large solar photovoltaic installations.
Due to the robuts tubular plate design BAE PVS batteries are excellent suited for highest requirements regarding cycling ability and long life-time.
