Things to Consider
We know that it can be overwhelming to choose one generator when there are so many options available. We assure you that all the suggested Firman models have been individually vetted because we want you to be happy with your purchase. However, we acknowledge that you might need some help narrowing down the choices. You must remember that you have to take into consideration the purpose for which you’ll be using the generator. Once you’ve answered that question, half your job is done. Then, you just have to go through our buying guide, which will help you to evaluate all your options, so you can make an informed choice.
Firman generators: What is special about them?
The Firman generators have exclusive proprietary technologies that go into their making, which set them apart from the other models on the market. You will be surprised at how many features, including the remote start, like some other best remote start generators feature, you get with these generators without having to empty your bank account. The company focuses on making generators so powerful that they can satisfy the customers. The Firman generators also come with bigger fuel tanks which allow them to run for longer stretches of time. You will no longer have to worry about re-fuelling every two hours. Firman is confident in its products, which is why all their generators come with warranty.
Generator type: inverter or conventional?
If you are confused as to whether you should go for an inverter generator or a conventional generator, then you should make your final choice based on your budget constraints. However, you should remember that inverter generators tend to be smaller and lighter as compared to traditional models. Hence, inverters tend to be more portable than standard generators.
Moreover, inverters are quieter and make less sound as compared to traditional generators. They cut down on power fluctuations so that you get a steady supply of power at all times.
How much power do you need?
If you want the perfect generator, then you must first understand how much power output you will be needing. As long as a generator is able to provide you with as much power as you need for your job, it is a viable option. In order to figure out the power output you will need, you have to sum up the power in watts that is required by all the appliances you will be running at the same time. You can use the voltage and the amps to calculate the amount of power they will need. Having a higher margin is a better idea than having insufficient output.
How long do you need to run your generator?
The generator you choose will also depend on how long you are planning to use it for. If you want a model that will run for a long stretch of time without having to get refilled, then you need to choose one that has a high fuel tank capacity. The run-time of a generator is directly proportional to its fuel tank capacity. It can be a hassle if your generator stops working in the middle of work, so you should invest in a model that can run for at least 8 hours at a time. This will give you enough time to use the generator and then refuel it.
In case you want to use multiple devices with the help of the generator, it is ideal to have multiple outlets. This will help in spreading the load and allow you to make the most of the available wattage. The feature is helpful when you are traveling or camping, and you need to power everything at once.
Nothing is more important than your well-being and safety. You should feel safe when using the generator that you have bought with your hard-earned money. Make sure that the model you buy is able to provide you with clean energy. This will protect you from voltage surges and give you a steady flow of current.
You should also look for a low-oil shut off safety feature in your generator. It means that the generator will stop working when the level of lubricating oil in the machine drops too low. This will protect the engine from excessive wear and tear. Some generators come with an automatic shutoff feature which helps in overload prevention. If your generator is unable to support all the machines that you have plugged in, then it will cut off the power supply in order to prevent mishaps.
Tips and tricks
The following tips will allow you to stay on top of the generator game.
You should not operate your generator indoors if it emits carbon monoxide. This can lead to carbon monoxide poisoning
Ideally, your portable generator should always be dry. Exposure to water can cause a complete breakdown.
Take some effort to understand the importance of the two capacity ratings. Do not confuse the rated/continuous rating with the starting/maximum rating.
You should never try to refuel your generator while it is still hot. Once it cools down, refuel it slowly so that there is no spillage.
Never back-feed a portable generator.
Make sure that you check the filter once a week. You should change the oil every 100 hours to ensure that the machine runs properly.
Do not be scared to be stock up on high-quality fuel because you never know when you might need it.
Firman generator prices
Firman generators are as good as high-tiered generators, but they are priced reasonably. You get access to some excellent features for a small investment. Firman believes in letting their generators speak for themselves and do not spend a ton on marketing. This allows them to keep their prices low.
For example, you can get an inverter generator for around $500 – check out the W01781 model. A mid-range conventional generator, like our top pick P03603, will cost you the roughly same. A larger and more powerful dual-fuel H08051 model is a bit pricier at almost $900, which is, however,
When you are investing in a piece of machinery like a generator, you would expect it to have a decent warranty period so that the company can step up and help you in case something goes wrong. Firman, as a company, stands up for the quality of its products and gives you a warranty on the generators that it manufactures. If you buy a Firman generator, you will get 3 years of limited warranty if you use it for residential purposes. On the other hand, if you are planning to use the Firman generator for commercial reasons, then the warranty will last for 90 days.
Firman inverter generators are definitely quieter than conventional generators. This is because the Firman inverter generators are designed in such a way that they can produce AC current without making noise. The design of the machine contributes significantly to the reduction in the sound. The Firman inverter generator ensures minimal movement inside the model, and it runs at a constant speed. The company makes mechanical provisions to minimize the noise.
Firman makes sure that all their generators come with mufflers to ensure that they do not produce too much sound when operating. The muffler blocks the sounds so that the user cannot hear it.
It is important that you use a generator that is safe and certified. If you want an eco-friendly generator that does not degrade the environment, then you should go for a model that has been approved by the CARB or the California Air Resources Board. CARB is all about environmental protection and targets air pollution as one of the biggest enemies of the modern world. You should get a generator that abides by CARB’s rules and regulations. All the Firman generators mentioned on our list are certified by CARB, which means that they’ve been deemed safe to use.
