APPLICATIONS
CASE HISTORY
ENERGY recommends
These generating sets are suitable for powering any type of equipment, provided it remains within the generator’s power output limits. If the generating set is used to power electronic devices (TVs, computers, inverter welders, etc.), we recommend the optional automatic voltage regulator (AVR). Although the soundproof enclosure is suitable for outdoor use, for any permanent installations, we recommend installing a canopy if the generating set is not placed in a dedicated room. The 3,000 RPM models are suitable for intermittent use. Improper use of the generating set can cause the engine to overheat and lead to wear on various components. Any damage caused by improper use of the generating set will not be covered by the warranty.

Energy’s professional generating sets offer reliable solutions for every power need, from residential to industrial settings.
The professional generating sets in Energy’s ACTIVE line are ideal for preventing power outages and ensuring a continuous power supply, and are perfect for construction sites and hobby projects. With gasoline or diesel engines and air cooling, they deliver optimal performance and durability in demanding conditions. Discover how these generating sets can provide a constant and reliable power supply, wherever you need it.
