Battery Equivalents and Replacements

Can I Run A TV Using A Power Generator?

Although even the smallest power generators are generally strong enough to power home TVs, even the largest ones, many people nonetheless ask if they can run their TVs using power generators. And they ask for a good reason.

When powering TVs using power generators, the output power of generators is not an issue. However, a waveform of the output voltage can cause various issues to modern TVs, laptops, tablets, audio devices, telecommunication devices, and similar devices.

Not All Generators Are Created Equal

There are two basic types of power generators, inverter power generators, and non-inverter power generators.

Non-inverter power generators have very simple control electronics which help smooth out the output voltage waveform, but it can't do much since the basic waveform is determined by the motion/rotation of the power generator - for example, if the engine changes the speed, so does the output voltage change the frequency.

Such non-inverter power generators feature Total Harmonic Distortions (THD) up to, or even more than 20%, which is too much for sensitive electronics.

Inverter power generators have more complex control electronics and their output voltage form and frequency don't depend on the engine speed. Such units feature very low THD levels, mostly below 3%, with some units featuring THD levels below 1% when not loaded more than 25-30% or similar.

So, if You want to power your TV directly from the power generator, consider buying an inverter power generator. Also, if it is going to be used in a residential area, consider getting a quiet unit - fully enclosed inverter power generators often have very low noise levels, sometimes even below 50dB @25% load, when measured from a distance of 21-23 feet.

The following comparison chart lists some of the best inverter power generators with very low THD levels and very low noise levels:

Power Generators vs. Solar Generators

While power generators burn fuel to create electric energy and thus must be operated outdoors, solar generators create AC power from the energy being stored in onboard batteries.

jackery 500

While the energy stored in the onboard battery is far from the energy stored in the fossil fuel, solar generators can operate indoors safely.

Also, many solar generators support "pass-through" charging - the solar generator can be recharged using, for example, solar panels and can provide AC and/or DC power to the external load, TV, for example.

Note: output voltage of most portable solar generators is pure sine waveform, with very low THD levels, making solar generators safe for powering TVs and other sensitive electronics.

Since smaller to medium TVs generally require less than 100 Watts, a medium-sized solar generator can power such TV for hours, making them preferred energy sources over power generators in many situations...
