Buyer’s Guide
A buying guide helps you make a well-informed decision. It lists down all the features you must consider before buying a generator. Let’s look at various features you must look for in a Firman generator.
Output and Power Needs
The most important thing to consider before buying a generator is power needs. Once you know what size generator you need, selecting the unit becomes easier. To get an idea about your power needs, list down all the appliances you will be powering on your generator. The next step is to mention the starting and running watts of each appliance. Consider the example below.
| Appliances | Starting Wattage | Running Wattage |
| Refrigerator | 1200 | 600 |
| AC | 1800 | 1200 |
| TV | 400 | 400 |
| Lights | 400 | 400 |
| 1/2 HP Well Pump | 2000 | 900 |
| 1/2 HP Sump Pump | 2000 | 900 |
| Security System | 800 | 800 |
| Total | 8600 | 5200 |
In the example above, you need 8600 watts for starting all the appliances and 5200 watts to keep them running at one time. The difference in the starting and running wattage is due to the motorized appliances. You can adjust this difference by starting heavy appliances one by one and turning off the unwanted ones. A generator with 5500 running watts will be ideal for the above example. A smaller generator has its perks; it is cheap, easy to maintain, and has a low running cost.
Type of Generator (Inverter vs. Conventional Generator)
If your power needs are less, let’s say below 3000 watts, a Firman inverter is best for you. For people with higher power needs, conventional generators are better. Inverters are lightweight, smaller, fuel-efficient, and produce stable electricity. They are best for running sensitive appliances like medical equipment, chargers, and computers. You can also use them to power RVs, use them during camping, and running some appliances during a power outage. An inverter can also be used at worksites if you need less power.
Conventional generators provide more power than inverters, are heavier, and have a high operational cost. They are best for people who need power above 3000 watts. You can use Firman generators to power medium to large RVs, campsites, worksites, and homes during emergencies. Conventional generators are noisy compared to inverters.
Type of Fuel
The third most important thing which affects usability is the type of fuel. With Firman, you have the option of going with a single fuel or a dual fuel. Firman offers gasoline generators in the single fuel category and propane/gas in the dual fuel generators. Gasoline has its advantages over propane, but it has some drawbacks as well. While it is easily available throughout the year, its availability comes into question during natural disasters, emergencies, and infrastructural problems. Gas has a short shelf life, and therefore it can’t be stored for emergencies. Propane, on the other hand, has a shelf life of 8-10 years. It burns cleaner than gas and is cheaper. However, it has a low energy rating as compared to gas. Propane is also safe to work with as there is no risk of spillage and fire.
Fuel Tank Capacity and Runtime
If you are planning to run your generator on gasoline, you must check the fuel capacity. Firman offers impressive gas tank sizes. If your generator has a big gas tank, it will provide more runtime than a generator with a small tank. For propane, the run time depends on the cylinder’s size and the load on the generator. To increase the runtime on both fuels, keep the load at or below 50% of the generator’s total rated output.
If you run your generator frequently for longer spells, a large gas tank will be helpful. For occasional users, a small gas tank will be fine.
Control Panel
Firman generators come with an advanced and yet easy-to-operate control panel. You will get all the options like on/off buttons, odometer, warning lights, choke, and power outlets. A control panel does not interfere with the working mechanism of the generator but helps make it user-friendly.
Outlets
Make sure that the unit you are buying has all the power outlets you want. Inverters come with USB outlets and AC/DC outlets to run appliances directly. If you plan to run your appliances directly on a conventional generator, ensure that it has enough outlets. If you are going to connect the generator to your home, then outlets won’t matter much. Safety tip: never connect a generator to your home without a transfer switch.
Portability
All the Firman generators are highly portable. The inverters are lightweight and easy to carry around. Conventional generators come with heavy-duty wheels which facilitate movement. A couple of models don’t feature wheels. So, if you are buying those models, you will have to invest in a wheel kit.
Starting Mechanism
Firman offers remote starting and electric starting in some models. It is up to you to select the starting mode. Firman’s remote start model has one of the highest ranges in the market. It comes with a 55 feet range.
Paralleling Capabilities
If you are buying a Firman inverter, make sure that it is parallel capable. The inverter on our list is parallel capable. You can connect two same models together and double the power output. It helps in running heavy machines which can’t be run on a single inverter.
Safety Features
Regardless of the brand, a generator must offer all the safety features in it. Firman generators come loaded with surge voltage protection, overload protection, and other safety features such as covered outlets and low oil shutdown.
Noise Level
Firman inverters are quiet compared to conventional generators, which have a noise rating of around 70-75 DB. If you aren’t comfortable with a high running sound, go for an inverter. For conventional generators, you may need to upgrade the exhaust system with the help of high-quality mufflers.
Warranty
All Firman units come with a warranty of 3 years. All parts and repairs are covered under the warranty agreement. We suggest you must go through the terms and conditions before starting your generator for the first time.
Price
Price is one of the selling points for Firman generators. Firman is providing high-quality generators at an affordable price. It is an excellent buy for people with a tight budget.
