What Determines Accurate Sizes of Inverters for You?

You will find size ratings of inverters ranging from 50 watts up to 50,000 watts in the market. Units under 11, 000 are primarily used for households and photovoltaic cells (PV). Sizes of inverters depend on things like watts, watt-hours, amps, and ampere-hours. Here is a brief description of these factors:

1. Watts: It refers to the amount of power used by a device. It is defined as 1 joule per second.

2. Watts-hours (kilowatt-hour) kWh: It is simply the watts times that a device is used for. For example, a light using 100 watts for 9 hours will be regarded as 900 watts-hours. 1000 watts-hour is equal to 1 watt for 1000 hours.

3. Amperes (amp): A unit that measures electric current at that moment. It is a determinant of the size of the wire towards the Direct Current (DC) side of the inverter. Amperes are known to generate heat in the wires. Ampere is defined as 1 Coulomb per second.

4. Ampere-hours (AH): It is the measurement of the capacity of the battery. It determines the time for which you can run the battery. Ampere x time = ampere-hours

What Size Inverter to Run a TV?

Generally, televisions are power-efficient, and they use less than 150 watts of power. Plasma is usually over 40 inches and requires an inverter of about 300 to 400 watts. Things to know include surge and time period to determine which inverter is ideal for your house.

1. Surge Rating

A surge rating is specified at how many watts for how many seconds. It simply tells the time for which the inverter will handle an overload of those particular watts. The surge rating or capacity ranges from 20% to 300%. In terms of time, an inverter with a 3 to 15-second surge rating is sufficient to cover 99% of household appliances.

2. Rules

An inverter with low surge ratings has high-speed electronic switching which is ideal for residential uses. An inverter with high surge ratings has low-speed electronic switching and is ideal for transformer-based switchers with low frequency.

Since televisions are not high-power consumers, you do not have to worry much about spending high amounts on expensive inverters. 100 watts to 200 watts inverters will do just fine but if you are still confused it will be better if you determine the exact power used by the TV.

3. The Amount of Power that your TV Uses can be Determined by the Following Factors:

  • Display Technology (LCD, LED or Plasma, etc.)
  • Model
  • Size (inches)
  • The easiest way to know the power usage of your TV is as follows:
  • From the specification sticker on the TV
  • From the energy guide label provided with your TV
  • With an electronic monitoring device

4. Continuous and Peak Hours Performance

Still, confused what size inverter to run a TV? Most inverters have two ratings, namely Continuous and Peak ratings. Continuous rating inverters provide power continuously and for extended periods. A peak load inverter provides power in short-term spikes. Peak load ratings of at least 20% are preferred. For example, an inverter rated and labeled as 900/600 has a continuous rating of 600. After this, let’s see-is it safe to run LED TV on inverter.

How Long Will TV Run on Inverter?

Two factors determining the time for which a TV can run on an inverter are:

  • Power usage of TV
  • Usable Capacity of the Inverter

Also, the time limit of an inverter for running a TV can be determined easily by understanding Peukart’s Law. If you want to get an accurate estimate of how long your deep-cycle inverter can power the TV, remember-

  • The higher power your draw
  • The lower the capacity gets

Peukart’s formula to calculate the time of battery:

Battery time = 20 ((AH / (Amps drawn * 20)) ^k)

Here, 20 (both) = Hours (battery was rated)

AH = Rated Amp hours of the battery

Amps drawn = (watts of TV / 12-volts / 0.85 inverter efficiency factor)

k = Peukart’s constant → 1.1 for AGM (Deep-cycle battery) and 1.2 for Flooded batteries

To understand what size inverter to run a TV better, here is an Example:

Find the time period of a 100 Ampere Deep-cycle (AGM) battery for a TV of 150 watts or fewer

(Watts= amperes*volts)

150-watt TV / 12-volts = 12.5 amperes

Peukart’s constant = 1.1

125 amperes or 0.85 efficiency of the inverter = 14.7 amperes needed from the battery

Therefore, battery time = 20 (((100 AH / (14.7 * 20)) ^1.1))

= 6.1 hours for a 100 AGM battery to get discharged completely.

Note: The table provides estimated hours. The hours provided may vary depending on the type of inverter and from location to location.

How to Calculate What Size Inverter Do I Need to Run A TV?

You already know the easiest way to know the power usage of the TV. However, to know the size of the inverter you can use the following formula and the Energy Guide Label. The yellow and black label at the back of your television tells you the estimated power consumed in kilowatt-hours per year.

Usually, the yellow patch tells you that if the TV is on for 5 hours per day it will consume about 94.3 kilowatt-hours or 94300 watts-hours of energy in 1 year.


Power usage (watts) = Yearly energy consumption (watts-hour) / (Run time hours (daily) * 365)

With the above-mentioned units, you can calculate.

Power usage (watts) = 94300 watts-hour / (5*365)

= 94300 watts-hour / 1825 hours

= 51.67 watts

Roundabout, the TV will approximately consume 52 watts of power from the inverter to run. This is how long will tv run on inverter.

What Size Inverter Will Run A TV With a Deep-Cycle Battery?
