Understanding Generator Set Ratings

It may become complex to understand the information shared along with your generator, which is why it’s helpful to go deeper into the ratings provided. By reviewing the set ratings of your generator, you can get a bird’s eye view of the performance delivered. You can also read through the extensive documentation provided, along with key safety tips that you should follow when running the generator.

It’s also important to find the right generator that works best within your specified needs. A high-power, high-output generator can work well for local businesses, as well as international enterprises. Key suppliers of bespoke generator machines such as those manufactured by Welland Power in the UK, often develop customized solutions for schools, manufacturing hubs, and warehouses for use in the US, Europe, Asia, and other countries worldwide.

What is the need for rating?

The basic purpose of a generator set rating is to determine the fit of the application with the machine. It’s important to understand the key benefits offered by the generator so that you can supply seamless power to the system. You can also review the cost, reliability, and equity of the brand when comparing multiple options against their set ratings.

There are also multiple ratings in the marketplace, making it a decision that requires diverse inputs. You can also focus on key factors such as load optimization, hours run, and isolated/parallel foundation. These can help you narrow down your options as you select the right one for your application.

The Emergency Standby Power rating (ESP)

The emergency standby power rating, or ESP, is a market standard rating that focuses on the maximum amount of power produced by the generator. Quality generator machines, such as Perkins, may be ranked higher in the ESP rating, owing to the superior output provided. ESP is a critical factor that comes into play during emergency outages requiring immediate supply of power.

ESP is also used extensively in various industrial applications which require a consistent supply of output. ESP rated generators must be able to provide power for the entire duration of the outage, with maintenance intervals as suggested by the manufacturer.

ISO standard ratings

ISO is an international standard rating given to the generator. It provides key insights into the quality of the overall make and takes into consideration major performance indicators, along with on-site applications that can be accomplished with the generator.

There are critical factors such as prime power, running time, and continuous power that add to the overall rating provided. ISO rating gives buyers clarity during the buying process. It also provides key details about the manufacturer’s equity in the space.

Continuous Power (COP)

Generators with higher continuous power (COP) ratings are more favorable to leverage for long-term applications. This is because they provide a more consistent charge, as the output is optimized for maximum utilization. A baseload power station may also be developed, as more consistent charge is provided by the generators.

There may be certain manufacturers that have their own version of COP, but most comply with a comparable rating that can be analyzed by industry buyers. They can also provide more information about the maintenance needed, and the output of the overall generator.

Load factor

The load factor is one of the most important set ratings to understand, as they provide key information about the utilization of the generator. By optimizing for the load factor, buyers can align their needs better to the power delivered by the machine.

The starting power requirements can be matched with the running time charge to get more information about the usage of the generator. Maximum run time can also be analyzed to get a better understanding of the performance of the generator. Manufacturers may list these details in conjunction with their own set of ratings.
