Buying Guide For Firman Generator

Yes, Firman generators are good products that come in high quality. However, there are too many variations, so we would like to help you narrow down your options. In order to do that, you have to learn to customize your selection based on some basic aspects of these machines. Let’s look at some of the specifics here.

Type of Generators

There are two basic types to differentiate between. They are – conventional and inverter. Which one you need will depend on where you want to use it and what kind of load you expect it to take.

Inverter generators are smaller in size than conventional ones. Therefore, if you want a portable device, then this one will probably be the better option for you.

Also, inverters are more stable in function. Due to their relatively smaller sizes, they cannot take as much pressure as a conventional generator can. To summarize, it could be said that inverters are better when you need to use it on the road, for example, in campsites and temporary workstations.

Whereas conventional ones are better for construction sites, big office or apartment buildings, and such other permanent establishments.


This is one of the main areas you need to look at when buying a generator. The decision for the type of generator is actually going to come after this. So, you have to figure out powerful the generator needs to be in order to support all the different appliances that will be running on it.

You can do this easily, but some calculations will be required. First of all, you will have to get a measure of the power requirements of each of the appliances that you expect to run on it. Use the voltage and the amp readings to calculate the power in watts. The combined wattage of all the devices will determine what power your generator should be able to put out.

To be on the safe side, get a generator with a higher power capacity than is your actual requirement. 

Fuel Tank Capacity

If you want to run your generator for long periods of time at a stretch, you need to get a machine that has a large fuel tank. Refilling is a hassle, and if you get a machine with a small tank for a heavy-duty job, then you will have to do it several times. It will just be an unnecessary inconvenience for you. 

The fuel capacity will be mentioned in the features of the machine, along with the run time. Look at the run time to decide whether the particular generator will be adequate for your necessity.

Safety Measures

The generator you get must be able to produce clean energy. This is to say that any toxic substances released in gaseous forms will be harmful to both the environment and the living beings around the area. Check for some particular safety adjustments like a low-oil shut-off system and an automatic shut-off system.

Low-oil shut off is necessary to stop the machine when the oil tank is almost empty. It will save the engine from getting jammed and burning out due to a lack of lubrication.  The automatic shut-off will ensure that the machine turns off by itself if too many appliances are connected to it at a time.
