25kVA Generators – common questions

FAQ

What is the fuel consumption of a 25 kVA generator per hour?

The fuel consumption of a 25 kVA diesel generator depends on its load percentage and efficiency. Running the generator at 100% capacity can consume 5-6 litres an hour, while a 75% load will consume up to 4.5 litres.

If a generator runs at 50% capacity, it will burn between 2.5 and 3 litres an hour.

However, these figures depend on the generator’s make, model and fuel type. Your manual will detail accurate fuel consumption levels.

What is the maximum load for a 25 kVA generator?

The maximum load of a diesel generator is calculated based on its power factor. While a 25 kVA generator can technically handle a maximum load of 25 kW, running it at full capacity could damage the components.

Instead, you should adhere to the power factor of 0.8, which means the maximum load will be 20 kW.

Where can I use a 25 kVA diesel generator?

Investing in a 25 kVA diesel generator is an excellent way to give your home or small business reliable standby power.

These generators aren’t meant for large-scale operations, but they can ensure vital appliances and equipment remain operational during a power cut while also providing reliable electricity for off-grid operations.
