6 kW Generator

6VSG Single Phase, Natural Gas|LPG

The generator made for renewable energy, including solar power or other remote applications. The KOHLER 6VSG battery-charging generator efficiently charges battery banks when renewable energy sources can't keep up with demand. If your battery charge drops below a pre-set level, the 6VSG charges it automatically.

  • High-quality power. The 6VSG provides consistent power to charge battery banks used with renewable energy, telecom and other remote applications.
  • Economical. The 6VSG is fueled by clean, affordable natural gas or liquid propane (LPG).
  • Remote control. Add the Programmable Interface Module and OnCue® Generator Management System to communicate with the 6VSG remotely.
  • Automatic. The generator senses when the battery bank is running low and turns on automatically to keep up with demand.


Designed specifically for efficient charging of battery banks for renewable energy, telecom and other remote applications; provides consistent direct-current output to maintain battery banks directly without inefficient conversions from alternating current

Can be used for industrial battery bus support to reduce the size of battery banks

Generator can maintain batteries directly without an expensive converter or monitoring equipment

Longer engine life and reduced fuel consumption when compared to fixed speed; variable engine speed (2300-2900 RPM) reduces maintenance requirements and fuel consumption and extends the life of the engine
