What Size Inverter Do I Need to Run a TV?


People would always buy and use the inverters to offer electricity for their homes. For example, some would use it to charge their air-conditioners, TV or a refrigiretor. Some may want to know what size inverter do I need to run a TV? Here, in this post, I would like to tell you about the questions for you to know more. 

First, you would require 250 to 300 watt of sine wave Hybrid Inverter to run the TV. Use the short distance wires to connect the inverter to the TV. The thin wire reduces the traction, which results in less energy loss. The more voltage would make the inverter supply energy efficiently.

Can You Run a TV off an Inverter?

The answer is yes. It is possible to run the TV off an inverter. Check the inverter’s output capacity as most of the inverters have limited output wattage. If the inverter can serve the required watt, then it will support the TV. You will be able to run the TV without any trouble. 

Such as, if the TV runs on 250 watts of power, it has inverters with 300-watt capacity.

You can start to consider the extra 20% watt for the power loss during the transmission of the energy.

The 300 watts of continuous output will keep the energy stable, and there will be no power loss and disconnection while watching the TV. 

Will a 300-watt Inverter Run a TV?

In fact, there is a wide range of inverters can be connected to household electronic devices. Inverters under 300 watts would be capable of powering the various types of electronics. Connect it to the vehicle battery through the DC and plug them on the dashboard of the vehicle.

At the same time, it is also easy for you to find the device that looks like jumper cables for connecting it directly to the battery.  On the flip side, almost all the modern inverters come with one or more standard switches to power regular household electronics such as laptops, TV, video game, or DVD player. Of course, you can also choose to run the kitchen appliances on the inverter comfortably. 

Connect the toaster, blender, etc., to the inverter and use it regularly without needing the regular power outlet.

Before you connect the TV to the inverter, check the watt requires to run the device. Always consider the 20% to 30% extra watt to power the device.

It will be useful to keep the extra watt on the power supply to compensate for the fluctuation in the energy. 

On the condition that you are going to connect multiple devices to the single inverters, check the watt of each piece of equipment and calculate the total watt, it would require to power the device.

One thing you need to remeber, do not use multiple devices if the inverter’s capacity is utilized above 80 to 90 percent of the total capacity of the inverter.

There has to be sufficient energy output to power the multiple devices, and else it will make it difficult for the inverter to run smoothly.

What Inverter Do I Need to Run a TV?

In fact, every electronic comes with a watt indicator showing how much electricity the inverter draws when connected to the power grid per hour. Generally, the energy uses is mention in the watt on the equipment.

You need to spend some time in checking the specification of the device to know the exact watt the device would require to run. 

Just take a note that the watt on the paper. The next step is the find how much watt your inverter draws from the output cable. Note that as well on the piece of paper.

Once you have to both calculations, calculate the watts required to run the equipment. The inverters must have 30% extra power than the total amount of equipment from the inverter.

The additional wattage ensures that the devices connected to the inverter would get sufficient power without any fluctuation in the output. 

Remember that there will be a voltage drop when you connect the electronic device. The 12v system would drop the 0.5v. So the inverter can only power the device that requires 11.5V power.

The equipment should be powered with a minimum voltage of 12V. Else, it will not run. So check your TV voltage requirement.

Always have 20% extra voltage if you want to run the device on the inverter. 

A 32 inch LCD tv consumes around 125 watts of energy. It would require an inverter that provides around 250 to 300 watts of energy to power the device.

The large the TV size, the more energy it will consume. You have to be very precise about the voltage your TV requires. 

How to Know the Exact Voltage the TV Draws?

You must need to know the precise voltage of the TV draws, right? The simplest way is to check the instructions so that you can understand totally the voltage the TV draws. You had better connect the right inverter to the TV. At the same time, it will solve the problem of the power inefficiency by connecting the inverter. 

On the flip side, you had better choose to use the cable, and it will charge enough power to the TV. 
When the energy is transported through the wires, the energy is lost in terms of heat. Thin wires will reduce energy loss as there will be less friction and more supply of energy.

How Do I Calculate What Size Inverter I Need?

Many people would feel confused when they buy the right inverter for their homes. If you want to know what size inverter you need, then you should know how much output it will produce to your settings. 

In general, regular inverters are calculated according to the wattage it draws. At the same time, the inverters will convert the power from the DC to the AC power before it is stored in the battery. Of course, there is some energy will be lost in the procession of conversion.

Furthermore, some voltage is consumed by the inverter to run the core process. The less power inverter consumes, the more efficient the system will become. Now, you must know what size inverter you need based on the power consumption. 


You have clearly understood the measurement procedure of the energy supply from the inverter and the depletion rate. Some inverters are very efficient in drawing energy. You do not have to consider loss. At the same time, you should know that keep the energy left to solve the fluctuation of the energy offer.
