What is Standby Generator Set and How to Choose a Generator Set?

A standby generator set is a backup power system that automatically starts and takes over the supply of power to a building or facility in the event of a power outage or interruption.


It consists of a generator that uses an internal combustion engine to produce electricity and an automatic transfer switch (ATS) that monitors the utility power supply and switches the electrical load to the generator set when a power failure is detected.


Standby generator sets are commonly used in a variety of environments, such as residences, commercial buildings, hospitals, data centers, and industrial facilities. In these environments, where an uninterrupted supply of power is critical, generator sets provide the necessary standby solution to ensure power continuity in the event of an emergency or when the main power source is unavailable.


How to choose the right equipment

Choosing a standby generator set requires careful consideration of various factors. The following is a guide prepared by AGG to help you choose the right product for your needs:

Calculate Power Requirements: Calculate the total power usage of appliances and equipment to be powered to determine the generator set's wattage capacity.

Fuel Type: Common generator set fuels include diesel, natural gas, propane, and gasoline, and the user selects the fuel type based on availability, cost, and preference.

Size and Portability: Consider the available space for the generator set and whether you need it to be portable or fixed installation.

Noise Level: Generator sets can produce a considerable amount of noise. If excessive noise is not an option, you need to choose a generator set that offers low noise levels or includes a soundproof enclosure.

Transfer Switch: Make sure the generator set is equipped with an automatic transfer switch. This device automatically switches power from the utility grid to the generator set in the event of a power outage, ensuring a safe and seamless transition, and avoiding damage caused by power outages.

Quality and Service: Finding a reliable and experienced generator set or power solution provider ensures excellent product quality, comprehensive support and service.

Budget: Consider the initial cost of the generator set and the long-term operating costs (fuel, maintenance, etc.) to determine your budget range for the purchase of the generator set.

Professional Installation: Proper generator set installation is critical for safety and optimal performance, and it is recommended that you seek professional assistance or choose a generator set or power solution provider that offers installation services.

Regulatory Compliance: Familiarize yourself with the permits required or regulations to be met for generator set installations in your area to ensure that the installed generator set meets all necessary codes and standards.


Remember, when in doubt, consult with a professional or team that specializes in power generation systems to help you make an informed, efficient decision.
