What is a Power Inverter?

Many appliances require alternating current to operate. The wall outlets in your home or office provide single-phase AC power (voltage level depends on your geographic location) that can be used to connect the devices you want.

However, a battery cannot supply alternating current. It can only supply direct current (direct current) which cannot be used to power common household appliances such as a refrigerator or television. In short, an inverter is simply a device that converts direct current into alternating current. Therefore, in the absence of a reliable AC supply, the inverter can be connected to a battery and used to operate devices that would otherwise be unusable.

From a technical standpoint, an inverter converts the DC waveform of a battery into a sinusoidal AC source that can power home appliances. Usually it is connected to a 12V battery (or several 12V batteries connected in parallel to increase its rated power) from which it draws power.

The 12V DC power supply is converted to a 120V AC power supply. The inverters can also be powered by 6 V, 24 V and 48 V batteries. You can now connect any appliance such as microwave, television, blender, coffee maker and even power tools to the inverter and get started. Since the battery is basically a storage device, it needs to be charged periodically after the inverter is used up.

Where can you use a Power Inverter?

In terms of usage, an inverter is an extremely flexible device and can be used to power a variety of home appliances from laser printers, entertainment units, lab equipment and your kitchen supplies to heavy machinery such as washers and dryers.

The inverter gives you access to portable power when and where you need it. Its versatility allows it to be used in many different ways: it can be used as an emergency power supply in your home, it can be used on camping trips and it can also be used in mobile vehicles such as RVs, food trucks, and boats. Later in this article, let’s look at the many different ways you can use an inverter.

Using a Power Inverter as Emergency Backup at home

Inverters are a great way to restore power to your home in an emergency. During power outages (especially in winter, when the heating system is not allowed to fail), the inverter can be used to operate essential appliances such as the refrigerator and heating or air conditioning systems.

Most people prefer to connect inverters to their car battery by placing the inverter close to the car and away from bad weather. For such applications, a 1750 watt inverter is most suitable. It is recommended to use ring terminals to connect the inverter to the battery instead of jumper cables to avoid loose cables.

Some commercially available inverters can also be connected to the car battery through the cigarette lighter port on your dashboard.

Although the inverter will work even when the car is not running, it is recommended that you leave the car on while the inverter is in use. This ensures that the battery does not discharge during prolonged use. Households without vehicles can purchase 12V rechargeable batteries to use during power outages.

The most reliable solution would be to have a battery bank for emergency backup, but such a solution would be quite expensive. When using batteries, it is essential to charge them regularly. Otherwise, the battery will go into deep discharge mode, which will kill the battery life.

An inverter has a power of watts. The manufacturer specifies two different ratings for the inverter: the continuous power determines how much power it can handle over a long period of time, and the peak power determines how much overload the inverter can withstand for a fraction of a second. A 1500-1750W inverter is suitable to run household appliances such as refrigerators and microwaves for three to four hours, as long as the battery lasts. (The power of the inverter must match the total load you want to use.

However, the inverter itself does not produce power, but converts battery power into a form suitable for AC appliances. Therefore, if the batteries that power it are exhausted, the inverter will not be able to operate any machine.

Using a Power Inverter for Camping

Maybe you want a quiet weekend without power, but you still want access to power to charge your phone, laptop, camera and coffee maker.

An inverter can help you to have such a portable power source. Since the energy requirement during a camping trip is not very high (unless you plan to take a fridge, air conditioning and washing machine into the woods), you can get by with a relatively cheap inverter.

Electronic loads, such as chargers for laptops and mobile phones, often have very light power requirements. A custom sine wave inverter rated at about 1000 watts would be helpful for your purpose. It’s best to carry a few batteries to power the inverter, although it can use your car’s batteries (this may not be the best option if your camping trip goes relatively wrong and you risk running out of it. to get gasoline).

Valve Regulated Lead / Lithium Ion (VRLA) batteries are the safest options to use. These batteries can also be charged

Using a Power Inverter inside a Mobile Vehicle

Maybe you want to hit the road in an RV, go sailing on your yacht, or maybe run your business from a food truck. In all these cases, an inverter can be used to turn on necessary appliances, such as refrigerators, lighting, coffee makers and microwaves.

Using an inverter in combination with a battery bank is more environmentally friendly than having a diesel generator on your vehicle. Also, especially if you are driving a food truck, putting diesel generators in the truck is a health violation. This is because many regulatory authorities consider a generator leak to be dangerous.

A 1750 watt inverter seems sufficient for use in a mobile vehicle. However, the rating of the inverter should be determined according to the power of the devices to be used. If you want a light inverter, you can opt for a modified sine wave inverter instead of a pure sine wave inverter. An inverter in combination with a battery bank is a robust and reliable power supply solution.

There are many reasons to use an inverter. It is versatile, portable and can be easily transported to remote locations. The inverter makes less noise than a diesel generator (no neighbors complain!), is environmentally friendly and makes life very easy.

It is a mature technology and is available in various configurations and classifications. The wide range of options makes it very easy to find something tailored for your desired operation. However, keep in mind that the power of the inverter must match the load you want to use.

Reliable battery configuration is required to power the inverter when traditional AC power is not available. If the batteries are empty, the inverter cannot supply the loads independently.
