What is AVR in diesel generator?

What is a Generator Automatic Voltage Regulator? An automatic voltage regulator (AVR) is a solid state electronic device for automatically maintaining generator output terminal voltage at a set value. It will try and do this as the generator load or operating temperature changes.

How do I know what AVR to use?

CHOOSING THE RIGHT AVR Multiply the total wattage of the appliance/s by three (3). Result will be the basis of which AVR to choose. When using the 110V socket, the total computed wattage of the appliance/s plugged in the AVR should not exceed 50% of the capacity of the AVR.

What is AVR function in generator?

An automatic voltage regulator (AVR) is a device used in generators with the purpose of automatically regulating voltage, which means that it will turn fluctuating voltage levels into constant voltage levels.

Can a generator run without AVR?

An Automatic Voltage Regulator or AVR, controls and maintains the voltage of the alternator in your diesel generator. Without an AVR or another system to perform the same function, the voltage would not be constant at steady state and wouldn’t recover to the correct level under load.

What do I plug in AVR?

If your appliance has electronic components inside that are especially sensitive to voltage surges, then we recommend you plug the appliance into an AVR. Example appliances that require an AVR would include: Computer systems, refrigerators, Aircon, Flat screen TV, Audio/Video equipment.

What size AVR do I need?

Determine the total wattage of your refrigerator For example, if your refrigerator has a rated input of 205W, a defrosting input of 150W, plus a 10W lamp, you should add them all together then multiply by 3. AVRs range from 500W all the way up to 5,000W.

Is AVR a must?

AVR is going to be pretty important if the voltage supply in your area isn’t stable. But unlike the surge protector which can only protect against voltage surges, the AVR is capable of compensating voltage dips as well, while also protecting your devices against voltage surges, albeit to a more limited degree.

Is it okay not to use AVR?

Almost forgot about something important, AVR with servo motor is loud but only if the voltage is instable. This means, if you are disturbed by the AVR loudness, the voltage is unstable. I would really suggest getting an UPS. Even if everything is stable, black out is still not good.

Is it bad to leave AVR on?

As long as there is sufficient ventilation around the AVR (ie. not overheating), leave it on if you prefer.
