What is a inverter generator - Everything to know

What is an inverter generator?

An inverter generator is a type of portable power generator that turns the direct current (DC) electricity from its battery pack to alternating current (AC) electricity.

Inverter generators are designed to provide a constant, high-quality power supply for sensitive electronics. Instead of using a gasoline engine as a source of power, these generators employ an inverter circuit to convert the direct current (DC) stored in batteries into alternating current (AC). Inverter technology allows for quiet, clean, and highly efficient portable power.

How do inverter generators work?

Inverter generators use a 1-phase induction motor as their power source. The AC current that is delivered by the generator is created when the engine’s crankshaft passes magnets, inducing an alternating magnetic field that causes electrons to flow in a manner similar to those from a transformer.

The alternating current is then rectified to direct current by the inverter, which turns the AC into DC for battery charging. The inverter technology used in these generators is based on the PWM (Pulse Width Modulation) methodology, which means that it produces power as a single-phase supply with high fidelity.

The process of converting the direct current stored in batteries into alternating current through an inverter circuit and inverter generator is similar to power converters and power inverters.

For example, you can use a power converter for your vehicle battery to run AC appliances with the car engine turned off. Similarly, an inverter generator is a great way to power sensitive electronics at home or outdoors without resorting to gas-powered generators.
Inverter generators make their eco-friendly technology possible by reducing their power consumption.

Inverter generators can also save you money. They produce a much lower level of carbon emissions than traditional gasoline generator models while bolstering fuel efficiency levels and making it easy to refuel at any time. Inverter generators are also a practical option for construction

What size inverter generator do you need?

Generally, Inverter generators come in a range of sizes, from 1 kW to 2.5 kW or higher. The wattage you need will depend on the appliances and electronics that you want to power simultaneously. If your generator isn’t large enough, it’ll have trouble powering larger items at once without cutting out.

If you plan on powering multiple items at once, you should choose a generator that offers wattage equal to or higher than the sum of all items. For instance, if you have a 1 kW air conditioner and a 1 kW space heater, you’ll need a 2 kW inverter generator.

When deciding on an inverter generator it is important to research each model so you can find the wattage, features, and price that fits your needs.

Note: It’s an average discussion by researching thousands of inverter generators. Well, there is an inverter generator called Briggs & Stratton which provides 6000 watts. Another generator named Generac iq3500 provides 3500 watts.
