Buying Guide
What to compare when choosing an inverter generator for home backup
- Power needs: Assess your essential circuits and total load. Choose a model with enough peak wattage and running watts to cover critical appliances.
- Fuel flexibility: Tri-fuel or dual-fuel options provide resilience when one fuel is scarce. Consider gas stations, propane supply, and natural gas availability.
- Safety features: CO sensors, low-oil shutdown, and low THD ensure safer operation near living spaces and electronics.
- Noise level: Quieter models (often around 60–65 dB) minimize disruption in residential areas.
- Transfer switch compatibility: If connecting to a home panel, ensure the generator supports transfer switches or is parallel-capable for added capacity.
- Run time: Look at fuel tank size and ECO mode effectiveness to estimate how long you can run essentials without refueling.
- Portability vs. capacity: Heavier units may offer more power but are harder to move; balance needs with storage and setup requirements.
Practical questions buyers ask

- Q: Can I run a whole-house load with a portable inverter? A: Yes, with a transfer switch and appropriate wattage, but verify that the generator’s running watts meet your loads.
- Q: Is low THD important for electronics? A: Yes. Low THD reduces the risk of damage to sensitive devices like computers and TVs.
- Q: How loud are inverter generators? A: Many models operate around 60–65 dB at a convenient distance; always check the rated noise level for your space.
- Q: Should I buy a generator with remote start? A: Remote start adds convenience during outages, especially when you want to power up before reaching the unit.
- Q: How much fuel does a typical backup generator use? A: Fuel consumption depends on load; ECO or economy mode helps optimize efficiency.
