Frequently Asked Questions
Q: What can a 9000 watt inverter generator power?
A: It can run major home appliances like refrigerators, air conditioners, sump pumps, and multiple lights or electronics simultaneously. Check each appliance’s wattage to ensure total load doesn’t exceed the generator’s capacity.
Q: How loud is a 9000 watt inverter generator?
A: Noise levels range from 50 to 70 decibels, similar to a normal conversation or vacuum cleaner. Inverter models are quieter than conventional ones, but always check specs for dBA ratings.
