Complete Diesel Generator Buying Guide

Buying a diesel generator is a significant investment that requires careful consideration. In this article, we review the most important purchasing tips.

1. Determine Required Power

The first and most important step is accurately calculating your power consumption. List all equipment that will run on the generator and note each one's power. Remember that motor loads (pumps, compressors) have high starting currents.

2. Choose Engine Brand

Reputable brands in the Iranian market include Perkins, Cummins, Volvo Penta, Caterpillar and MTU. Each has its own advantages and disadvantages.

3. Application Type

Will the generator be used for standby (emergency) or prime (continuous) power? This is crucial for capacity and type selection.

4. Environmental Conditions

Altitude, temperature and humidity affect generator performance. At altitudes above 1000m, derating applies.

5. Warranty and After-Sales Service

Minimum 2-year written warranty and access to genuine spare parts are among the most important purchasing factors.
