Buying Guide: Standby Diesel Generator Purchases
Power needs and site requirements drive the best standby diesel choice. Start with these considerations to compare models and accessories:
- Power output and load profile: Determine peak wattage and continuous load. For food trucks or small business trailers, 5-40 kW units cover most needs, but plan for startup surges from compressors, pumps, and refrigeration.
- Fuel capacity and runtime: Larger fuel tanks extend runtimes. Consider fuel availability, refueling logistics, and the environmental impact of diesel fuel on your operations.
- Emission standards: Tier IV and other emissions ratings influence permissible installations, especially in urban or compliant areas.
- Portability vs. stationary install: Open-frame or portable units are easier to move, while dedicated standby generators may require professional installation and transfer switches.
- Maintenance and service: Kits, filters, and parts compatibility affect long-term reliability. Identify local service centers and readily available parts.
- Noise and retreat requirements: Some markets require noise limits or enclosure options. Assess decibel ratings and sound attenuation features.
- Accessories and expandability: Additional fuel tanks, remote start options, and transfer switches can enhance reliability and ease of use.
- Safety considerations: Proper ventilation, exhaust routing, and compliance with electrical codes are essential for safe operation.
