Solar batteries for professional applications such as hospitals, SAC huts, telecommunications etc.
OPzS 2 volt batteries are built for professional use and due to tube technology and armor plates a lifespan up to 20 years and can, in extreme cases up to 15,000 times to be unloaded and reloaded. This extremely robust built-in batteries are suitable for medium and large solar systems with a voltage of 24 or 48V and a capacity 285-4770 Ah. The block batteries are connected in a corresponding rack so that we arrive at the desired tension. The batteries require very little maintenance and have a large reserve of water so that the water resp rarely refilled. controlled muss.Das housing is made of transparent high-quality SAN (styrene-acrylonitrile) plastic. Thanks labyrinth plugs aerosols are actively retained. The dimensions corresponding to DIN 40736-1 and the batteries are thus compatible with other manufacturers and can therefore replace several other brands. On request, we also offer maintenance-free GEL supply variant (OPzV), this option is more expensive.
