Best Inverter Generators for Home Backup Buying Guide
Understanding Wattage Requirements
Before purchasing, calculate the total wattage of the appliances you intend to power. Running watts represent the continuous power needed, while starting watts are the higher surge required to kick-start motors in appliances like refrigerators or air conditioners.
Ensure your chosen generator's running wattage exceeds the sum of your essential appliances. Using a generator that is consistently pushed to its maximum capacity can reduce its lifespan and fuel efficiency.
The Importance of Clean Power
Inverter generators are distinct because they convert AC power to DC and back to a clean AC wave. This process results in low Total Harmonic Distortion (THD), which is critical for protecting sensitive microprocessors found in modern TVs, computers, and medical equipment.
Traditional generators often produce 'dirty' power that can cause flickering lights or damage to delicate electronic components. For home backup, choosing an inverter model is a safer investment for your household technology.
Fuel Types and Storage
Gasoline is the most common fuel, but it has a limited shelf life and requires stabilization. Dual-fuel or tri-fuel generators offer a significant advantage by allowing the use of propane, which stores indefinitely and is often easier to procure during extended emergencies.
Consider your storage capabilities when choosing a fuel type. Propane tanks are safer to store long-term, while gasoline requires careful management and rotation to ensure it remains usable.
Noise Levels and Neighborhood Considerations
Inverter generators are engineered to be significantly quieter than open-frame or traditional models. This is particularly important if you live in a dense neighborhood where noise ordinances might apply during an outage.
Look for models with an ECO mode, which adjusts engine speed based on the electrical load. This not only reduces noise but also significantly improves fuel efficiency during light-load periods.
Safety and Maintenance
Modern generators include essential safety features like CO-sensors that automatically shut down the engine if dangerous carbon monoxide levels are detected. Always operate your generator outdoors in a well-ventilated area, away from windows and doors.
Routine maintenance, such as checking oil levels and using a fuel shut-off valve to drain the carburetor, will prevent common starting issues. Proper care ensures your generator is ready the moment you need it.
Frequently Asked Questions
Can I use an inverter generator for my entire home?
Most portable inverter generators are designed for 'essential' backup, meaning they power specific circuits or appliances rather than an entire house. For whole-home power, you would need a much larger standby system.
What is the benefit of a tri-fuel generator?
A tri-fuel generator provides maximum flexibility by allowing you to switch between gasoline, propane, and natural gas. This ensures you can keep the generator running even if one fuel source becomes unavailable.
How often should I run my generator for maintenance?
It is recommended to run your generator at least once a month for 15-30 minutes under a light load. This keeps the engine lubricated and ensures the fuel system remains clear.
Are inverter generators safe for my computer?
Yes, inverter generators produce clean power with low THD, making them safe for sensitive electronics like computers, smartphones, and smart home devices.
What does 'parallel ready' mean?
Parallel ready means the generator has ports that allow you to connect a second, identical unit using a parallel kit. This effectively doubles your power output when you need to run more appliances.
