Yes, regular generators can damage electronics if you don’t lower the THD levels of the generated power.

However, certain generator types like inverter generators and standby generators will typically not damage electronics thanks to their built-in technologies for lowering THD levels.

If you already have a regular generator and want to power sensitive electronics anyway you will need your own inverter, suitable voltage regulators, or a power conditioner to clean up the electricity.

Is a generator safe for electronics?

No, a regular generator is typically not safe for electronics by itself. Non-inverter generators produce high THD power that can damage your electronics.

However, there are inverter generators that have an inverter built-in to lower the THD levels of the generated power. This type of generator is typically safe for electronics as long as you follow all the safety guidelines.

Standby generators are typically safe for electronics too because they often have surge protection built in.

So some but not all portable generators are safe for electronics. Standby machines tend to be prepared for powering sensitive electronics.

Can a generator ruin your appliances?

Yes, a regular generator can ruin appliances that have electronics if you don’t lower the THD levels of the generated power yourself.

On the other hand, inverter generators and standby generators will typically not ruin your appliances if you follow all the generator safety guidelines.

There are also some appliances that don’t use electronics. Even a non-inverter generator should not ruin these.

Will a generator hurt your TV?

Yes, a regular portable generator without an inverter will hurt your TV due to the high THD levels of the produced power.

That being said, inverter generators and standby generators can typically run your TV safely if you follow all the other important guidelines too.

Can a generator damage a PC?

Yes, a regular generator can damage a PC if you don’t lower the THD levels yourself. The high THD power can damage the electronics inside of the PC.

However, there are inverter generators and standby generators that typically don’t hurt your PC because they produce low THD power.

How to make a generator safe for electronics

The main ways to make a generator safe for electronics are:

  • Use a separate inverter
  • Use a suitable voltage regulator
  • Use a power conditioner

Because adding an inverter to a generator is hard, many people prefer to get a good inverter generator or standby generator to power their sensitive electronics instead.

How to protect a TV when using a generator

To protect a TV when using a generator you need to make sure the generated power gets cleaned up by devices like an inverter, certain voltage regulators, and power conditioners.

Using an inverter generator or standby generator that produces low THD electricity by itself is another way to protect your TV. These generators for electronics are typically more convenient.
