Is a 700kVA diesel generator right for my site?

That depends on the critical load and how it behaves in operation. Assess running demand, starting currents, future capacity and the consequences of failure. A site survey helps establish whether a 700kVA diesel generator is appropriate.

What is the difference between standby and prime power?

Standby power supports the site when the mains supply fails. Prime power describes a generator used as a regular power source over extended periods and changing loads. The duty must match the application.

How is fuel consumption calculated for a 700kVA generator?

Fuel consumption varies by generator model, engine, loading and operating conditions. Use the technical specifications for the proposed unit and assess the expected duty, rather than relying on a generic hourly figure.

What should be included in a 700kVA generator installation?

The scope depends on the site. It can include mechanical and electrical works, a control panel, fuel tank, exhaust arrangements, commissioning and the equipment needed to integrate the generator with the existing power system.

Why is load bank testing important?

A load bank applies a controlled resistive load. Testing helps verify generator performance and can identify developing faults before a real outage. The test regime should reflect the site risk and compliance requirements.

Can Solent Power support sites outside Southern England?

Solent Power provides servicing and rapid response across Southern England. It can support large projects and multi-site contracts throughout the UK. The appropriate support arrangement should be agreed for the project or maintenance contract.

700 kVA Generators

Investing in a 700 kVA diesel generator gives you access to reliable standby and prime power. Whether you want to safe-proof your commercial business or streamline industrial power needs, these generators are powerful enough to handle large loads.

Silent Power is one of the UK’s most popular generator distributors, giving our customers access to fantastic prices and reputable manufacturers. Take a look at our generators, and please feel free to contact our friendly sales team for more information.

Why choose a 700 kVA diesel generator?

Diesel generators come in a variety of sizes, with 700 kVA models being at the higher end of the scale. Renowned for their reliability and durability, these generators are designed for large-scale operations or powerful equipment.

Here’s why you might want to choose a 700 kVA generator.

Power output

These generators can power large operations or environments with high power consumption rates. While you can find a more affordable smaller generating set, it might not be able to handle busy periods or emergencies. Opting for a 700 kVA model gives you peace of mind.

Durability

Diesel generators are reliable and can operate for long periods, making them powerful backup energy sources for businesses. The models we stock also use industry-grade materials, ensuring they maintain performance even in extreme weather conditions.

Fuel efficiency

Modern diesel generators have advanced features that enhance their efficiency. Diesel is a naturally efficient fuel type, so running these generators is less expensive than using traditional gasoline. Choosing a model with a load management system will prevent the fuel tank from draining constantly.

Versatility

Most people use 700 kVA generators for standby power, as they’re large models that aren’t really portable. In some cases, these generators can also be ideal for outdoor events, including musical concerts and festivals. They perform best as permanent fixtures in businesses and homes.

Investing in a diesel generator with Solent Power means you’re always getting quality

At Solent Power, we take pride in ensuring that every generator we sell is tested for quality. Our extensive quality control process ensures that you receive the best possible model for your budget.

We stock generators from the UK’s most reputable manufacturers, including CAT, Pramac, and Cummins. Each comes with an excellent engine and control panel and is manufactured in accordance with strict guidelines.

Whether you need a new diesel generator or are investing in one for the first time, please discuss your needs with our expert sales team. We also offer a generator installation service and ongoing maintenance.

700kVA Diesel Generators (560kW) – common questions

FAQ

What is the fuel consumption of 700 KVA generators per hour?

The average fuel consumption of a 700 kVA generator can be anywhere from 120 to 160 litres hourly, depending on your chosen model and its energy efficiency. The load you’re using and the condition of your generator will also define fuel consumption levels.

That’s why it’s vital to consider whether buying used generators is a good idea. Yes, they’re more affordable, but you should always check for previous maintenance logs, including whether the generator was prototype-tested.

What is the maximum load for a 700 kVA generator?

A 700 kVA generator can support a maximum load of 700 kVA (560 kW, assuming a power factor of 0.8). Simply put, your 700 kVA generator will supply up to 560,000 Watts, but this depends on your chosen model.

Most specialists recommend running the generating set at 80% to prevent issues, including overloading and overheating.

Where can I use a 700 kVA diesel generator?

The best thing about 700 kVA generators is their versatility. While they’re powerful enough for a range of settings, it’s best to use these generators for the following applications:

Industrial: Whether it’s heavy machinery, factory production lines or other high-consumption equipment, 700 kVA diesel generators are equipped to deliver consistent and uninterrupted power in industrial settings.
Commercial buildings: Hospitals, large office blocks and shopping centres rely on a consistent electricity supply. Power outages can result in lost profits and frustrated customers. If a hospital doesn’t have access to backup power, people’s lives could be in danger.
Data centres: Data centres handle large amounts of personal information and rely on a consistent electricity supply. Outages could cause extensive security breaches.
