Purchase Ideas

1. Brands and Reputation

When it comes to finding the best whole house electric generator, the reputation and history of the brand play a crucial role.

2. Power Output and Capacity

Power output and capacity are significant factors to consider when purchasing a whole house electric generator. Your generator should have enough capacity to power your entire home, which means it should have a wattage rating that meets or exceeds your household's needs. To calculate your power requirements, add up the wattage of all essential appliances you plan to run simultaneously and choose a generator with a higher output than that total.

3. Fuel Type and Efficiency

Whole house electric generators can run on various fuel types, such as gasoline, diesel, propane, or natural gas. Each fuel type has its pros and cons, and your choice should depend on factors like availability, cost, and storage requirements. Gasoline is the most common fuel type, but propane and natural gas offer longer shelf life and cleaner emissions. Diesel generators are known for their fuel efficiency and durability.

4. Noise Levels

Nobody wants a noisy generator, especially when it's running for extended periods. Look for generators with low decibel (dB) ratings, as they produce less noise. Some models come with advanced technology and sound-dampening features, ensuring your generator operates quietly and doesn't disturb your neighbors or household members.

5. Warranty and Customer Support

Lastly, a comprehensive warranty and reliable customer support are essential when investing in a whole house electric generator. Top brands often provide warranties covering a few years or even a limited lifetime warranty, ensuring your investment is protected. Customer support should be easily accessible, offering assistance and guidance when needed.
