Best inverter generators

How to choose

Size: 2,000 W for camping, 4,000 W+ for an RV or the house

A 2,000 W-class inverter runs a fridge, lights and electronics. RVs with a 13,500 BTU roof AC need about 3,000 running watts, or two small inverters in parallel. Large 7,000 to 9,000 W inverters can back up a home with clean power.

Look at the noise figure

Manufacturers usually publish dB(A) at 23 feet (7 meters) and a quarter load. Under 60 dB(A) is conversation level; small inverters reach the low 50s.

Parallel capability

Two parallel-capable inverters linked with a kit double the available power while each unit stays light enough to carry. See parallel generators explained.

Mistakes to avoid

• Assuming every inverter has 240 V: most small ones are 120 V only, which rules out a 240 V well pump.
• Comparing noise figures measured at different distances or loads.

Frequently asked questions

What is an inverter generator?

A generator whose output goes through electronics that turn it into clean AC power with low harmonic distortion. The engine speed follows the load, which saves fuel and lowers noise.

Are inverter generators better than regular generators?

They are quieter, more fuel-efficient and safer for electronics. Regular open-frame generators cost less per watt and offer more 240 V outlets for home backup.

Can an inverter generator power a house?

A large inverter (7,000 W and up) with a 240 V outlet can back up a house through a transfer switch or interlock kit. Smaller inverters are best for a few circuits through extension cords.
