How to Choose Generators

Understand Wattage Needs

Wattage is a key factor when choosing a generator. Look for generators with at least 5000 running watts for commercial tasks. This ensures enough power for tools and equipment.

Consider Fuel Type

Generators can run on gasoline, propane, or both. Dual fuel options provide flexibility. Gasoline offers more power, while propane can give longer run times. Choose based on how you plan to use it.

Look for Portability Features

If you need to move the generator often, check for weight and design. Generators around 100 pounds or less are easier to transport. Look for built-in handles or wheels for added convenience.

Check Run Time

Run time tells you how long the generator can operate. Aim for at least 8 hours at half load. This is important for long workdays without frequent refueling.

Safety Features Matter

Look for generators with safety features like low oil shutdown and CO sensors. These features protect both you and the equipment from damage during operation.

Frequently asked questions

What is the best generator for commercial use?

The best generator for commercial use is the Westinghouse 12500 Watt Dual Fuel Generator. It offers high wattage and dual fuel options for flexibility.

How much power do I need for commercial equipment?

For most commercial equipment, a generator should provide at least 5000 running watts. This supports tools without issues.

Are dual fuel generators worth it?

Yes, dual fuel generators provide flexibility. You can choose between gasoline for power or propane for longer runtimes.

How long can I run a generator continuously?

Most generators can run between 8 to 14 hours on a full tank. It depends on the load and fuel type.

What safety features should a commercial generator have?

Look for low oil shutdown, CO sensors, and overload protection. These features help prevent accidents and damage.

What to look for

Power Output

The power output of a generator is important for commercial use. Generators with higher wattage ratings can handle more demanding tools. Look for options with at least 5000 running watts. This is a good benchmark for typical commercial tasks.

Fuel Efficiency

Fuel efficiency affects operating costs. Generators that offer longer run times on a tank of fuel will save you money. Aim for models that can run for at least 8 hours at load. This reduces the frequency of refueling, which is important in commercial settings.

Noise Levels

Noise levels can impact work environments, especially in residential areas. Check the decibel rating of a generator. Aim for models under 70 dBA for quieter operation. This is a common noise level for outdoor generators.

Portability Features

Portability is key when moving generators to job sites. Look for wheels, handles, and lightweight designs. Generators should ideally weigh 100 pounds or less for easier transport. This makes setup faster and more convenient.

Safety Certifications

Safety certifications indicate reliability and compliance with safety standards. Look for generators labeled as EPA compliant. This ensures they meet environmental regulations and reduce harmful emissions.
