Things to Consider When Choosing a Firman Generator in Nigeria

1. Power Needs

Before you buy a Firman generator, you need to consider how much power you will need to power up the appliances you need. You can know exactly how much power you need by identifying the wattage of your essential appliances. Then add them together to determine the minimum starting and running watts required.

How To Know Your Power Needs

Calculating Your Power Needs

Let’s say your essential appliances and their wattages are as follows:

      1. Refrigerator:
        • Starting Watts: 1200W
        • Running Watts: 200W
      2. Air Conditioner:
        • Starting Watts: 2200W
        • Running Watts: 1500W
      3. Television:
        • Starting Watts: 300W
        • Running Watts: 300W
      4. Laptop:
        • Starting Watts: 100W
        • Running Watts: 100W
      5. Light Bulbs (4 bulbs, 60W each):
        • Starting Watts: 240W
        • Running Watts: 240W

To find the minimum starting watts required, add the starting watts of all the appliances:

1200W (Refrigerator) + 2200W (Air Conditioner) + 300W (Television) + 100W (Laptop) + 240W (Light Bulbs) = 4040W

To find the minimum running watts required, add the running watts of all the appliances:

200W (Refrigerator) + 1500W (Air Conditioner) + 300W (Television) + 100W (Laptop) + 240W (Light Bulbs) = 2340W

So, you will need a generator that can handle at least 4040 starting watts and 2340 running watts to power these essential appliances.

Determining The Appropriate kVA rating

To determine the appropriate kVA (kilo-volt-amperes) rating for a generator that can handle the power requirements, you can use the following steps:

  1. Calculate the Total Wattage:
    • Starting Watts: 4040W
    • Running Watts: 2340W
  2. Convert Watts to kVA: The formula to convert watts to kVA is:

The power factor for most household appliances is typically around 0.8.

Using the highest value (starting watts) for safety and future-proofing:

A generator with at least 5.5 kVA capacity would be suitable to handle the starting and running power requirements of your appliances.

2. Budget

There are lots of Firman generators to choose from depending on your power needs and budget. But at the end of the day, your budget will likely determine what Firman generator you end up with. 

If you’re on a low budget and have a high power need, you’ll likely have to save up some more, borrow, or make a loan. If you can’t do any of that, then you’ll have to settle down with the least of the best generators on this list; the Sumec Firman SPG4000E2 3.5KVA.

3. Starting Mechanism

The starting mechanism is also an important aspect to look at especially if you’re looking for ease of use and budget. If you’re looking for ease of use, look for a Firman generator with an electric start, like a key or switch. But keep in mind that they are usually the expensive ones in the bunch.

On the other hand, if you’re on a budget, look into getting a Firman generator with a recoil start, where you’ll have to pull a cord to start the generator. These types are usually less expensive than their electric start counterpart but they are not the best when it comes to ease of use.

4. Noise Level

It’s soothing to hear a generator run without trying to damage everyone’s eardrum. Sumec Firman owns a range of generators with quiet operation as their forte. But they all come at a hefty price. 

If price isn’t your concern, then you might need to consider the Sumec Firman ECO4990ES 6.5KVA Key Start 100% Copper Generator and the Sumec Firman Twin Cylinder TGG12000E2 12KVA Generator on this list.

5. Warranty

Warranty length and coverage can be important for some people. I mean, you don’t want to wake up to the reality that your brand-new generator just stopped working after one month of use. Now you can’t do anything other than find a mechanic to fix it and you cover the costs.

Sumec Firman is offering a 3-year warranty on all new generators purchased from them. This warranty also covers all defects the generator might have in the space of the warranty coverage period. 


There is a perfect Fireman generator for you. All you have to do is draft out what you want from your generator. This will be your buying guide to choosing the right Firman generator for your home or business.
