Buying Guide
Key considerations when selecting a 50 kVA generator:
- Power requirements: Estimate total startup and running watts for essential circuits to avoid overload.
- Fuel type and availability: Dual-fuel options offer flexibility during shortages; consider propane availability for longer outages.
- Portability vs. fixed installation: Choose portable units for RVs or campsites; fixed standby units for homes or facilities with dedicated transfer equipment.
- Noise and emission controls: Look for quiet-mode, CO detection, and CARB/EPA compliance for residential or outdoor use.
- Outlets and compatibility: Ensure outlets match your devices, RV requirements (NEMA 14-50R), and transfer switch compatibility.
- Maintenance and serviceability: Favor models with clear data displays, easy maintenance access, and remote monitoring if needed.
