Compared to batteries, the Pentadyne VSS+dc has higher reliability, vastly lower cost of ownership, near-zero maintenance, 99.998% uptime availability, much longer useful life, accurate state-of-charge monitoring, no runtime degradation over thousands of deep cycles, no health & safety hazards, insensitivity to temperature fluctuations and environmentally responsible.

The VSS+dc are primarily used to replace lead-acid batteries used in continuous power quality systems. The VSS+dc can also be integrated with adjustable/variable speed drives for protection against voltage sags and brief power disturbances.

Pentadyne focuses primarily on power quality applications and on emerging applications such as energy recycling.
