Firman Generator ~ Choose the Right Size and Model for Your Needs

Reviewed by [reviewed_by]

There are many reasons for a homeowner to consider a Firman generator. It’s one of those purchases that can be an investment in your family’s safety and comfort when damaging weather leaves you without power for days on end.

In addition, Firman generators can also provide dependable power on construction job sites, for home renovation projects, when dry-camping, or if all RV power hookups are taken at your campsite.

The beauty of Firman generators is that they offer a wide range of generator sizes and types, including portable generators, inverter-type generators, dual fuel, and Firman tri-fuel generator models. Each of these types of generators will feature state-of-art power technology and smart control features.

Which Firman Generator Is Right for You?

The main decision for new generator buyers is to know which size generator will fit your current and future needs in wattage power. Also, consider how you plan to use the Firman generator. Here are 5 questions to ask that will help you narrow in on the right Firman generator for your specific situation:

Will available fuel sources be of concern?

If so, then choose a Firman generator that has flexible fuel options like the Firman Tri-fuel Generator T07571 7500W/9400W that runs on gasoline, propane, or natural gas and a larger fuel tank of 8 gallons capacity to keep power running longer.

A dual fuel option to consider is Firman H07552. It runs on gas or propane. Best dual fuel generators

Do you require a generator that is very mobile and easy to maneuver?

If yes, then consider the Firman 3000W portable generator that only weighs 90 pounds. It features a compact size of only 23.2″L x 17.8″W x 17.9″H and comes equipped with rear rolling wheels. Best portable generators

Are you concerned about generator safety and family-proofing against accidents?

Of course! Then select a Firman Whisper series generator that has a low oil shutdown and a noise rating of 58dB @ 1/4 load. That’s equivalent to the sound of an air conditioning unit running 100 feet away.

Do you want a generator for emergency use during a power outage?

If yes, then review the section on how to select the right generator size with the right wattage output to meet your needs. Consider a Firman T08071 that boasts 10000/8000 watts of power at 50A 120/240V.

Are you looking for a budget-priced Firman generator to start new work projects or home improvements?

Then consider a robust, small-to-medium wattage generator. A smaller generator like a 5000/4000 watt, Firman P04001 Performance Series generator, will suffice if you’re only using one or two tools at a time.

Conventional Generator vs Inverter Generator

Before learning more about the wide range of Firman generators that are available, it might be important to know why inverter generators are so popular in the power-producing industry. Inverter generators provide clean power that is free of power spikes that can fry sensitive electronic equipment or power dips that can cause data and computing systems to fail or reboot.

Like inverter generators, conventional generators also have a fuel-powered engine. But, because these engines feature electromechanical functions between the alternator and the engine’s rotating parts – any fluctuation in the power being generated will result in what is known as harmonic distortion.

Power conversions will always present some level of harmonic distortion that is typically caused by varying, nonlinear loads. This harmonic distortion can have detrimental effects on electrical equipment such as blown fuses, fried computer boards, reduced motor life, and appliances running hot.

An inverter generator solves the problem of dirty electricity from generators because the initial AC is converted into direct or DC current which is then sent through a microprocessor that converts the DC current back into a clean, AC sine wave without spikes or dips.

One of the main reasons why inverter generators are so quiet is because the motor’s RPM is held steady and without excessive revving or idling, which is not the case with older electromechanical generators. Learn more about inverter generator vs generator.
