- The type of TV (LED, LCD, plasma, etc.)
- The number of hours you plan to use your TV
- The efficiency of your inverter
- The capacity of your battery bank (if applicable)
Calculating Your TV’s Power Requirements
The first step in selecting the right inverter size is to calculate your TV’s power requirements. You can find the power rating of your TV on the manufacturer’s label or in the user manual. Typically, the power rating is expressed in watts (W).
For example, let’s say your TV has a power rating of 200W. However, this is not the only factor to consider. You also need to take into account the TV’s startup power requirements, which can be significantly higher than its running power requirements.
A general rule of thumb is to multiply the TV’s running power requirements by 2-3 to account for startup power requirements. In this case, the total power requirement would be:
200W (running power) x 2 (startup power) = 400W
Considering Efficiency and Overhead
In addition to your TV’s power requirements, you also need to consider the efficiency of your inverter and any overhead power requirements. Inverter efficiency refers to the percentage of DC power that is converted to AC power. A high-efficiency inverter can minimize energy losses and reduce the overall power requirements.
Overhead power requirements refer to any additional power requirements, such as those for your TV’s built-in DVD player or gaming console. To account for these requirements, you can add 10-20% to your total power calculation.
Using our previous example, the total power requirement would be:
400W (TV power) x 1.1 (10% overhead) = 440W
Inverter Types and Their Suitability for Running TVs
There are several types of inverters available, each with its own strengths and weaknesses. When it comes to running TVs, you’ll want to consider the following inverter types:
- Modified Sine Wave (MSW) Inverters: These inverters are suitable for running simple TVs with minimal power requirements. However, they may not be suitable for more complex TVs with built-in DVD players or gaming consoles.
- Pure Sine Wave (PSW) Inverters: These inverters are ideal for running high-definition TVs and other sensitive electronics. They provide a clean and stable AC power output, minimizing the risk of damage or interference.
- Quasi-Sine Wave (QSW) Inverters: These inverters offer a compromise between MSW and PSW inverters. They provide a more stable AC power output than MSW inverters but are less expensive than PSW inverters.
Choosing the Right Inverter Size
Now that you’ve calculated your TV’s power requirements and considered the efficiency and overhead, it’s time to choose the right inverter size. A general rule of thumb is to select an inverter that is 1.5-2 times the total power requirement.
Using our previous example, the recommended inverter size would be:
440W (total power requirement) x 1.5 (safety factor) = 660W
In this case, a 660W or 700W inverter would be suitable for running your TV.
Additional Considerations
When selecting an inverter, you should also consider the following factors:
- Surge Capacity: Look for an inverter with a high surge capacity to handle startup power requirements and any unexpected power spikes.
- Efficiency: Choose an inverter with high efficiency to minimize energy losses and reduce your overall power requirements.
- Noise Level: If you plan to use your inverter in a residential area, look for one with a low noise level to minimize disturbance.
- Certifications and Compliance: Ensure that your inverter meets relevant safety and regulatory standards, such as UL or CE certification.
Conclusion
Choosing the right inverter size to run your TV requires careful consideration of several factors, including your TV’s power requirements, inverter efficiency, and overhead power requirements. By following the guidelines outlined in this article, you can select an inverter that provides reliable and efficient power to your TV, ensuring seamless entertainment without any interruptions.
Remember to always consult with a professional if you’re unsure about selecting the right inverter size or have specific requirements that need to be addressed.

Note: The table above provides a general guideline for selecting an inverter size based on TV power requirements, efficiency, and overhead. However, the actual inverter size required may vary depending on specific circumstances.
What is an inverter and how does it work?
An inverter is an electronic device that converts DC (direct current) power from a battery or solar panel into AC (alternating current) power, which is what most household appliances, including TVs, use. The inverter works by using a combination of electrical circuits and software to convert the DC power into a stable AC output.
The inverter’s output is designed to mimic the AC power provided by the grid, allowing you to run your TV and other appliances safely and efficiently. When choosing an inverter, it’s essential to consider the power requirements of your TV and other devices you plan to run, as well as the capacity of your battery or solar panel system.
How do I determine the right inverter size for my TV?
To determine the right inverter size for your TV, you need to calculate the total power required to run your TV and any other devices you plan to connect to the inverter. Check the TV’s power rating, usually listed in watts (W), and add the power ratings of any other devices you plan to run simultaneously. Consider the TV’s startup power surge, which can be higher than its running power.
Once you have the total power requirement, choose an inverter with a capacity that exceeds this value. A general rule of thumb is to oversize the inverter by 10-20% to account for any unexpected power surges or spikes. Additionally, consider the inverter’s efficiency rating, which can affect its overall performance and ability to handle the power requirements of your TV and other devices.
