Buying Guide
What matters most when selecting a 22 kW standby generator?
- Power needs: Confirm you can run essential loads (hvac, water heater, refrigeration, lighting) during an outage. Aim for a generator with enough continuous wattage and acceptable surge capacity.
- Transfer switch: A 200 A outdoor-rated, service-entrance switch simplifies installation and protects your system. Decide if you want a standalone switch or one bundled with the generator.
- Connectivity: Remote monitoring helps you stay informed. Cellular connectivity provides updates even when Wi-Fi is down; Wi-Fi offers convenient local monitoring.
- Fuel type and efficiency: Natural gas and propane are common; consider consumption, efficiency features, and fuel availability at your home. Some models offer optimized fuel control to reduce ongoing costs.
- Noise and footprint: Look for features like quiet operation, mufflers, and physical size constraints for your installation space.
- Warranty and service: A longer warranty typically means lower risk over time. Verify what is covered and the availability of local service providers.
