SEO FAQs
Can a 5000 watt inverter generator run a whole house?
While it cannot power a 4000-sq-ft home with central A/C, it can easily handle critical loads. A 5000-watt unit can run a refrigerator, several lights, a sump pump, and a window A/C unit or furnace blower simultaneously.
What is the advantage of an inverter generator over a standard one?
Inverter generators throttle their engine speed based on the load, making them significantly quieter and more fuel-efficient. More importantly, they produce “clean” power with low Total Harmonic Distortion (THD), which is required for sensitive electronics like laptops and TVs.
Is dual-fuel worth the extra money?
Yes, especially for emergency preparedness. Propane doesn’t degrade over time like gasoline does, and it’s often easier to find during a natural disaster when gas station pumps are down due to power outages.
How loud is 52 dBA on a generator?
52 dBA is roughly the sound level of a refrigerator humming or a normal conversation between two people. It is quiet enough to use in a campground without disturbing others or to keep in your driveway during a neighborhood power outage.
Does a 5000 watt generator need a transfer switch?
If you want to power hardwired appliances like your furnace or well pump safely, a transfer switch is highly recommended. For plug-in items like lamps and fridges, you can simply use heavy-duty extension cords.
