Engineered by Könner & Söhnen (Dimax GmbH, Germany)

The KS 48VS-DC is a high-efficiency DC generator designed specifically for battery-based energy systems, solar installations, off-grid homes, telecom sites, and backup infrastructures. Delivering up to 60 A of stable 50–55 V direct current, it charges 48V battery banks significantly faster and more efficiently than conventional AC generators, with no need for external rectifiers or complex conversion equipment.

Compact, powerful, and engineered with German precision, the KS 48VS-DC is an ideal component for modern hybrid systems and long-duration backup applications. For users seeking even greater fuel flexibility, the DC generator line also includes the dual-fuel KS 48VGS-DC, capable of operating on both gasoline and LPG.

Advanced DC Technology for High-Efficiency Charging

• Direct battery connection
  Provides pure, efficient DC output - ideal for solar-hybrid systems, telecom rooms, server facilities, and off-grid battery storage.

• Fast charging performance
  Comparable to 7–8 kW AC generators when used for battery charging—significantly reducing runtime and fuel consumption.

• Smart integration options
  The external “dry contact” terminal enables automatic start/stop and compatibility with hybrid controllers and modern power systems.

• Multi-mode start system
  Automatic  and  external start options adapt to any configuration.

Designed for Modern Energy Networks

• Safe low-voltage operation (48 VDC)
  Eliminates the risks associated with 230 V AC systems.

• Auto mode
  The generator activates only when required, monitoring battery levels and ensuring uninterrupted power supply.
