Westinghouse WGen3600v

Westinghouse WGen3600v

I just want to clarify that the Westinghouse WGen3600v is an out-of-the-box device that has huge power potential. It is a number higher than the rest of the products presented due to the fact that its starting power is already 4650 watts, together with the usual constant of 3600 watts.

In addition, the charge of this device will be enough for more than 13.5 hours of work if you fill a full tank, and its capacity, by the way, is 4 gallons, which is quite a lot. Despite such a steep potential along with the price, the offer seems more than great. The only drawback is, perhaps, the low level of portability. The device is really terribly heavy, so you need to calculate in advance where you will put it and how you will use it.

Difference between inverter and conventional generators

Inverter generators

The principle of operation of an inverter generator is very simple. Obviously, your generator motor produces and supplies you with high voltage multiphase AC power. Next, after generating AC, your inverter generator converts the power to DC. Later, the built-in inverter in your generator converts DC to AC again.

As such, it is important to understand that your inverter is built with a microprocessor that is designed to perform this conversion. Likewise, inverters are specially designed to provide smooth, stable, clean, and constant power. In addition, certain models of inverter generators can produce power that matches the power that utilities provide to your home.

Conventional generators

A conventional portable generator is a liquid-fueled engine with an alternator that has electrical power. When choosing, it is also important to consider that engine speed and associated electrical power are key characteristics of a conventional portable generator.

The main disadvantage of most portable generators is that the unit cannot maintain a stable 3600 rpm. This means that voltage and hertz also fluctuate and rarely stabilize. Harmonic distortion is a very important aspect of a generator, which is why this type of device does not generate pure electricity.

There is also a relationship between the size of the fuel tank and the quality and duration of the operation. Now imagine what size the generator will be for, say, 9000 watts. Compared to inverter generators, these will be much less portable.

Buyers Guide

What are the key differences between a 3000 watt inverter generator and a conventional generator

Each user needs to independently decide which type of generator is best for him and I will help you with that. In fact, I described some of the differences above, so I propose to talk about the rest now.

Power consumption and fuel efficiency

Remember that conventional portable generators can produce more power than inverter generators. First of all, this is due to the size of the fuel tank, which is always 1-2 gallons larger.

In turn, inverter generators using final alternating current are more energy efficient. In addition, the inverter usually adjusts itself to the load and calculates the required amount of energy.

Thus, the higher fuel efficiency of inverter generators allows the use of smaller fuel tanks which will not be a disadvantage.

Unlike inverter generators, conventional generators are not as economical. This is precisely the reason for their large size and heavyweight. Based on this, the so-called difference in power appears. For example, the average power of inverter generators is between 1200 and 4000 watts, while conventional portable generators can reach over 10,000 watts.

Portability issues

As you have already noticed, every review has a mention of portability, as it often becomes a decisive factor when choosing a generator.

Inverter generators are generally more portable than conventional generators. Conventional fuel-fired generators, while producing more power, have a large fuel tank and a larger engine. Based on this, 2 problems arise: the availability of space for placement and noise.

Undoubtedly, large generators often have wheels and carry handles, but this is often not enough since many portable generators still weigh over 100 pounds.

In turn, inverter generators are smaller due to the small fuel tank. Moreover, they do not need a large motor because they provide less power output. Because of this, the weight indicator drops by 50 percent compared to conventional generators.

Ecological aspect

We live in the 21st century, where the problem of environmental pollution is very acute. Thus, the choice of a generator between the 2 types also has a moral aspect.

In some countries, there are different restrictions on the emission of greenhouse gases into the atmosphere, so study this aspect before buying. In most cases, a portable generator must meet at least the EPA requirements. There are also CARB requirements that work in a number of other countries.

It is clear that inverter generators already emit less greenhouse gas emissions than conventional electric generators. It is easier to find an inverter generator that meets environmental requirements than it is to find a conventional portable generator that does.

Noise problems

Noise issues are really important depending on where you intend to use the generator. I just want to remind you that conventional portable generators are notorious for their noise. And unfortunately, this cannot be fixed in any way, so when choosing, remember that you need to put it away from people, parties, etc.

Speaking of inverter generators, the technology introduced allows them to run quieter. Inverter generators operate at a stable speed of 3600 RPM, which eliminates most of the noise.

By the way, in the instructions and in the case of the device, the noise level is often indicated. Most manufacturers indicate the decibel output of the alternator at half or fourth load, so keep that in mind.

Many inverter generators produce noise from 50 to 60 decibels, however, check the exact values ​​when purchasing. Compared to conventional generators, this is very good, as they produce over 65 decibels.

What can you run on a 3000-watt generator?

When choosing a generator, you must first understand what consumption sources will be connected to the station.

And after determining the consumers are connected to the generator, the power of all intended devices must be integrated simultaneously. Thus, the power of each gadget is better looked at in the technical passenger passport or at the device power ticket.
For example, here is a standard, average set of electricity consumers that a 3000 W generator can handle:

  • Refrigerator – 100-750 W;
  • Computer – 400-750 W;
  • Electric kettle – 1000-2000 W;
  • Lighting – 20-250 W;
  • Water pump – 500-900 W;
  • Air conditioner – 1000-3000 W.

Generator maintenance tips

Here are some recommendations for generator maintenance, following which you can be sure that the generator will start when you need it.

Change of engine oil

Like any other engine, the generator engine requires timely maintenance, one of the main points of a timely oil change. I recommend changing the running cycle a little and replacing it after 10 and 20 hours of generator operation, and then once a year or every 100 hours. If the generator is operated under severe conditions, the oil change interval should be reduced to 50-70 hours.

Sparks and filters

Without a good spark and sufficient airflow, the generator will intermittently or stop starting altogether. Replace plug and air filter every 200 hours of use, or once at the beginning of each season. A new spark plug paired with a clean air filter will maintain the correct air/fuel mixture, helping the generator engine run more efficiently, which will significantly extend the life of your generator.

Store the generator with an empty tank

If you do not plan to use your generator for more than a month, be sure to drain the fuel from the tank, then start the engine and wait until it stops. If there is still a little fuel left in the tank, you can unscrew the sump on the faucet and drain the remains.
