Generator efficiency calculator

How to use the calculator

1. Enter the Input Power (kW) - the electrical power input to your generator.
2. Enter the Output Power (kW) - the electrical power your generator is actually producing.
3. Click the "Calculate" button to determine the efficiency.
4. The calculator will display the efficiency percentage and show the formula used.

Understanding Generator Efficiency

Generator efficiency is a measure of how well a generator converts input power (fuel energy) to output power (electrical energy). It is expressed as a percentage.

A higher efficiency means the generator wastes less energy, resulting in better fuel economy and performance. Typical generator efficiencies range from 20% to 95%, depending on the type, size, and quality of the generator.

Practical Tips

• For accurate measurements, use a clamp meter or power meter to measure both input and output power.
• Efficiency tends to decrease as the load on the generator decreases.
• Regular maintenance can help improve generator efficiency.
