Koyama NPS Series Solar Batteries are specifically designed with revolutionary long life heavy duty plate gel technology for solar power storage.Solar batteries are traditionally hard working batteries and are usually cycled on a daily basis as part of primary power source of electricity where no grid power is available


Solar batteries are an intricate component for off-grid electrical systems such as solar, wind, and mini hydroelectric systems.

All these systems produce DC electrical which must be stored so that it may be used at a later time. In order to do this at the present time we use deep cycle batteries.

Deep cycle batteries are used because they have the ability to be recycled many times. This means that they can go from being charged to being discharged to 50% numerous times without damaging the batteries unlike that of other batteries such as cranking batteries which are used to start vehicles.
