Buying Guide
- Power demand: Calculate your essential load (refrigeration, heating/cooling, sump pumps, lights, and devices) to choose wattage. Higher-wattage units cover more loads but require more space and a larger fuel supply.
- Fuel type and availability: Decide between natural gas, propane, or diesel, and consider fuel accessibility in outages and at your property.
- Standby vs portable: Standby generators offer automatic transfer and seamless restoration; portable models provide flexibility and lower upfront cost but require manual setup.
- Remote monitoring: Cellular or Wi‑Fi monitoring helps with real-time status and maintenance alerts, but may require ongoing subscription for full features.
- Installation requirements: Standby systems need a licensed installer, transfer switch, and proper clearance. Portable units need safe outdoor placement and power connection planning.
- Noise and footprint: Consider noise ratings and space available on your property. Some models emphasize quiet operation and compact design.
- Maintenance needs: Engine type, oil changes, and routine checks affect long-term reliability. Choose brands with proven service networks.
FAQ
- What is an automatic transfer switch? It detects power loss and automatically reroutes loads to the generator, restoring power without manual intervention.
- Do all generators support remote monitoring? Many modern standby units offer cellular or Wi‑Fi monitoring, but some portable models may not.
- Is a bigger generator always better? Not necessarily. Ensure the unit meets your essential load needs without excessive surplus capacity.
- Can I install a standby generator myself? Standby systems should be installed by a licensed professional to meet safety codes and electrical standards.
- What maintenance do these systems require? Regular oil changes, spark plug checks, and periodic testing are common; check the manufacturer’s guidelines.
- How long can a generator run during an outage? Runtime depends on fuel supply and load. Ensure adequate fuel storage or a continuous fuel source for the expected outage duration.
