Kohler 6VSG 6 kW Generator
PRODUCT ](https://manuals.plus/wp-content/uploads/2022/08 /Kohler-6VSG-6-kW-Generator-PRODUCT.png)The Kohlerr Advantage

High-Quality DC Power
- 6 kW DC generator designed specifically for renewable
  energy applications and other remote applications
- Provides consistent DC 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
Quiet and Economical
- Variable speed helps to keep noise low and reduce fuel consumption as compared to fixed-speed AC generators
- The generator can maintain batteries directly without the need for an expensive converter or monitoring equipment
Flexible
- Generator senses when the battery bank is running low and automatically turns on to maintain batteries when renewable energy sources cannot keep up with demand
- Generator can also be set up to turn on when the renewable system’s inverter sends a signal
- Compatible with positive or negative grounded systems
- 24, 36, and 48 volt configurations
Reliable
- 18-month/1000-hour warranty for off-grid applications
- 5-year/2000-hour warranty for on-grid applications
