Can I Use A Stabilizer With A Generator? - (2023)

Stabilizers are power-saving products that protect your other electronics. However, concerns arise over when to use a stabilizer, especially if your power supply comes from different sources, like a generator. To clarify the issue, we have asked experts, and here is what they have to say.

You can use a stabilizer with a generator. However, using a stabilizer can increase the electric power drawn from your generator and damage a low volt-ampere generator. Besides, if your generator is functioning properly, you do not need to use a stabilizer.

Stabilizers and generators are major home electronics. In some occasions, you might need one and not the other. Yet sometimes they do work together. Stay put and keep reading to learn more about how stabilizers work with generators.

Can I Use a Stabilizer With a Generator?

Stabilizers were made because of voltage fluctuations and power surges. They can help to secure and stabilize the electric voltage going into your electronics from your power supply so that when the power fluctuates, it doesn't affect your electronics.

This voltage fluctuation can come from shortcomings in your power supply or a sudden change of electric weight on your power system.

On the other hand, generators are appliances that convert mechanical energy to electrical energy, which can be used for electrical appliances in the event of a power shortage. Depending on the type you get, many generators support high-voltage electrical equipment.

Generators hardly have sudden power fluctuation problems. A good generator has a steady output, although if you have challenges with the generator, it might be one of these issues: low fuel quantity, low fuel quality, or incorrect fuel.

You can check out some DIY generator repairs if you have such an issue. There is a need for generator repairs if power fluctuation shows up. Instead of using a stabilizer, it is better to carry out intense repairs or buy a new generator.

Using stabilizers with generators is needless. It will not cause damage to high kilovolt-ampere (kVA) generators, but if your generator gives you a stable power supply, then stabilizing isn't necessary.

Remember that stabilizers consume high voltage, so if you are using a low kVA generator or an older model, it is advised you not use a stabilizer alongside. Using it alongside your low kVA or old generator can cause damage to your generator, which will not be good.

How Many Watts Does a Stabilizer Consume?

A stabilizer will likely consume more voltage than if you plugged your appliances without it. But its voltage consumption depends on the competence of the stabilizer. That is why you should check out a stabilizer purchase guide before you purchase it.

A regular stabilizer should take 2-5% of the full load. This means that if you have a 1kVA stabilizer, about 40 to 50 watts will be lost. This would show on your utility bills if you let the stabilizer run all the time.

To reduce your bills while using a stabilizer, consider shutting it off while you are not using it. With that, it will cost you less. It wouldn't be good leaving the house with your appliances on.

Can I Use Inverter With Stabilizer?

Can I Use A Stabilizer With A Generator? - (5)

The work of an inverter is to change direct current (DC) to alternate current (AC), AC is the only form of current your electronics can use. Inverters are usually connected to charged batteries or directly to a solar panel.

If you have low voltage coming from your mains, then you can connect a stabilizer to your inverter. Sometimes they come with built-in stabilizers -in this case, you will not need one, or you can get a stabilizer for them.

If you get an external one, make sure the connection takes these routes: from the mains to the stabilizer and then to the inverter. This is the best arrangement; it will help your inverter charge faster and increase your inverter output, especially if you buy a stabilizer with at least twice the wattage of your inverter.

If your regular stabilizer cannot fit well for your inverter, do not consider connecting the stabilizer to the inverter, it is better to connect your electronics directly without a stabilizer. Sometimes a stabilizer is needless if the voltage from your inverter is stable.

If you fall short of this arrangement and connect the stabilizer to the inverter, you may wear out your inverter faster because it will add electrical load to the inverter.

Stabilizers come in different types, sizes, and for different uses. You should check out the best inverter stabilizers before you use or purchase one for it.

How Do You Regulate The Voltage of a Stabilizer?

Can I Use A Stabilizer With A Generator? - (8)

Having a generator during an emergency blackout is always relieving, but the challenge this can have is in the regulation of the voltage. Low voltage may not be able to carry all the electrical load and cause battery undercharge, while a high voltage may damage appliances, cause burnouts, or overcharge the battery.

The AVR is responsible for the regulation of the voltage of your generator. If you need to regulate the voltage of a generator to the fitted measurement, here are the steps to take:

  • First, you can look for the voltage dial. It is by the sides of your generator and adjusts the voltage. If your generator doesn't have that, continue with these steps.
  • Adjust the choke of your generator; by doing that, you increase or decrease the RPM (rotation per minute).
  • By simply listening, you'll know when you've increased or decreased it.
  • When increasing the RPM, you increase the voltage output. By reducing the RPM, you reduce the voltage output.

Always remember to check your user manual for guides and to know the sustainability of your equipment.

Do Surge Protectors Help With Generator?

Can I Use A Stabilizer With A Generator? - (9)

A power surge is a device that helps to protect your appliances against sudden electrical spikes which can cause damage to your appliances. They also act as an extension socket where you can plug multiple appliances at the same time.

It serves as an intermediary between your power supply and your appliances. They work by directing the extra energy to the ground wire whenever there is a power spike. Power spikes can burn equipment. They usually last for milliseconds, but can cause major damage to your appliances.

Power surges are majorly caused by electric companies during grid switching, but not always. Lightning and switching on or off large house equipment may also cause power surges.

Your generator can give out power spikes, especially when it is faulty, so it is important to install a power surge in your home, which can be used alongside your generator.

Having a power surge will save your appliance damage and save you cost on the repair. It is easy to maintain.

Install only the best power surges to save money on circuit repair.

Does Using Stabilizer Increase Electric Bills?

Stabilizers, as the name implies, help to give your appliance a standard voltage and will protect your appliance whenever there are voltage fluctuations. To do this, stabilizers take 2-5% of the full load. This is very negligible, but if you keep them running for the whole day, it will queue up on your bills.

The trick is not to install a stabilizer for the whole apartment, use them for specific appliances. Whenever you are not using the appliance, switch off the stabilizer.

How Do I Choose a Stabilizer

You should take careful considerations when choosing a stabilizer; not only are they expensive, but an unsuitable one may cause further damage. You should consider the frequency of electric fluctuations in your area and the voltage ratings of your appliances.

To get the best type of stabilizers, these are some things you should know.

Type of Indicator

Indicators are display lights that can show you power fluctuation; new models come with LED lights.

Overload Protection

You should always look for good overload protection; it will turn off stabilizer output in case circuit overload occurs.

Type of Mounting

Mounting is a very important issue. If you do not have a proper place to keep ground stabilizers, you should consider one that is mounted on the wall to avoid water or any other liquids from touching it.

Other things you may want to consider can include the warranty and if it is digitized. Newer or latest models of stabilizers are produced to suit all situations. It is good to check for the best that suits your budget

Bottom Line
