Guardian Elite 48 kW Standby Generators MODEL QT04842

GUARDIAN is now doing to the commercial market what it has already done to the residential market... making standby power reliable, yet affordable. Protect your revenue stream by investing in a GUARDIAN Elite Commercial Series automatic standby generator. Our GUARDIAN Elite Commercial generators are ideal for a broad range of enterprises, including restaurants, convenience stores, supermarkets, banks, fitness centers, hotels, and retail outlets.

All Elite Commercial models are available in both single and three-phase configurations. They run on either natural gas or LPV, feature automotive style, liquid-cooled engines and GUARDIAN's exclusive Whisper-Test feature. Our 22, 27, 36 and 48 kW premium models come standard with higher displacement, low speed engines and aluminum enclosures. Aluminum enclosures are optional on the 60 kW and larger models.

Whisper Quiet Operation
GUARDIAN's exclusive Whisper-Test low speed exercise feature makes our GUARDIAN Elite products the quietest liquid-cooled generators on the market. Whisper-Test reduces noise by 50% during the generator's weekly self-test cycle allowing for near silent operation that satisfies all known sound ordinances.

Optional Transfer Switches

The transfer switch monitors utility power and signals the generator to start when utility power is interrupted. When utility power returns, the transfer switch returns the electrical load from the generator back to the utility. This ensures your most important electrical loads are powered, within seconds, even when you’re away. Unlike other brands, GUARDIAN includes an automatic transfer switch as standard equipment with all air-cooled models.

These transfer switches are also available for liquid-cooled models or as an alternative to be purchased separately.
