If your inverter generator isn't producing power, it can be frustrating and even a safety hazard. This is often due to a faulty inverter board, which can be caused by overheating or a manufacturing defect.

The inverter board is a crucial component of an inverter generator, responsible for converting DC power to AC power. It's a small but vital part that can be easily damaged if not handled properly.

A loose or corroded connection can also prevent your inverter generator from producing power. This can happen if the terminals or wires are not securely attached or if moisture has accumulated on the connections.

In some cases, a faulty fuel filter can restrict the flow of fuel to the engine, causing the generator to not produce power.

Troubleshooting Steps

Let's get to the bottom of why your inverter generator isn't producing power. The first step is to check the basics - is the generator properly connected to the electrical panel and outlets? Make sure the generator is turned on and the circuit breaker hasn't tripped.

A faulty circuit breaker or a blown fuse can prevent power from flowing. Check your generator's circuit breaker or fuse box to see if any of the breakers are tripped or if a fuse has blown. If so, reset the breaker or replace the fuse.

Low oil levels can also cause a generator to shut down or not produce power. Check the oil level and add more if necessary. It's a good idea to check the oil level regularly to prevent this issue.

A clogged air filter can reduce airflow and cause the generator to overheat, shutting down or not producing power. Check and clean the air filter regularly to ensure good airflow.

The major reasons for not producing power, as mentioned earlier, could be the result of a faulty alternator or a malfunctioning control panel. If you've checked the basics and the generator is still not producing power, it may be worth consulting a professional to diagnose and repair the issue.

Common Issues

If your inverter generator is running but not producing power, it's likely due to a few common issues. One major reason is that the generator is not getting enough fuel, so make sure the tank is filled and the fuel line is not clogged.

The generator's circuit breaker might have tripped, causing a power outage. Check the breaker and reset it if necessary.

Your inverter generator might be overheating, which can prevent it from producing power. This can be caused by a clogged air filter or a malfunctioning cooling system.

The issue might also be due to a faulty or loose connection in the electrical system. Check the connections and wiring for any signs of damage or wear.

A malfunctioning governor or speed control can also prevent the generator from producing power. This is often due to a faulty sensor or a problem with the governor's mechanism.

Before calling for professional help, try to diagnose the problem yourself and look for ways to fix it.

Power Output Problems

Power Output Problems can be a real headache, especially when you need electricity from your inverter generator.

One common issue is that the generator runs, but doesn't produce any electric power. This can be really frustrating, especially if you need to power essential devices.

If the generator runs but no power output from it, it's likely due to a problem with the generator's working and operation.

You might be worried if you're unfamiliar with how generators work, but don't panic! Every generator owner will face this problem at least once.

A problem with the outlets can also prevent you from accessing the generator's power. Outlets are the main point of access to the generator's power, so if they're faulty, you won't have any power at them.

Even simple parts like outlets can go bad, causing the generator to run but not produce power. This can be due to damaged wiring, bad contacts, or a damaged outlet.

To fix the issue, you'll need to delve into the generator's inner workings to understand why it's not producing electricity.

Electrical connections are often overlooked but can be a major culprit when it comes to an inverter generator not producing power.

If your generator is running but not producing power, it might be due to poor electrical connections. This can be as simple as dust and debris clogging the ports.

Make sure to thoroughly remove any particles, debris, or clogs from all ports and verify that all connections are securely tightened.

12 Volt Method

The 12 Volt Method is a great way to troubleshoot generator issues. Locate the voltage regulator for your generator, it's usually a key component in the electrical system.

To start, unplug the two wires that connect to the generator brushes, one is typically red and the other is black or white. Make sure to unplug the brush wires from the automatic voltage regulator to avoid damaging it.

Connect the black or white wire to the generator ground battery terminal, this will help you test the system. Plug in a light, turn on the generator breaker or switch, and start the motor to see if the system is functioning correctly.

For three seconds, connect the battery +12 volts (red cable) to the red wire on the terminals you removed. This will give the system a temporary boost.

Remove your wires and replace the plug, then check if the generator is producing power again. If these instructions don't help, the next step is to replace the Automatic Voltage Regulator as it may be damaged.

Preventive Maintenance

Preventive maintenance is essential to avoid generator issues. Consistently maintaining your generator will prevent most problems, such as it stopping power production.

Regular maintenance can be done by yourself or a professional service. It's crucial to do it consistently and thoroughly on a regular basis to ensure the best running capabilities.

The Pleavin Power team offers personalized maintenance services to generator owners across the UK. Their team of experts will provide a completely tailored approach to each client.

Consistent maintenance will negate most of the issues you're likely to encounter with your generator. This includes problems like it stopping power production.

Having a reliable and sustained power source for months or years to come is crucial. Regular maintenance will ensure your generator runs smoothly and efficiently.

#2 Poor Connections

Poor connections can be a major culprit behind a generator's lack of power output. This is often due to dust and debris clogging the ports, especially if the generator has been stored in a garage or shed.

If you haven't used your generator recently, it's likely that dust and debris have accumulated in the ports. This can be easily fixed by thoroughly removing any particles or clogs.

Improper connections can also cause a generator to run but not produce power. This is especially true if you've left the generator in a garage or shed where dust and debris are a problem.

To resolve insufficient connections, you should thoroughly remove any particles, debris, or clogs from all ports and verify that all connections are securely tightened. This simple fix can often resolve the issue and get your generator up and running.

Circuit Breaker and Outlets

A circuit breaker tripping is a common issue with inverter generators, and it's usually a safety feature designed to protect the system from damage.

The circuit breaker in your generator is there to break the circuit if it detects overcurrent, which can happen if you overload the circuit with too many devices.

Regular circuit breakers trip only in the event of overcurrent, while GFCI breakers trip upon detecting a ground fault, in addition to overcurrent conditions.

If the circuit breaker is damaged or has a problem, the circuit won't get electricity, regardless of the type of breaker.

A tripped circuit breaker means the generator won't produce electricity, even if it's running.

One of the reasons a circuit breaker trips is if you overload the circuit with too many devices and appliances.

In the case of GFCI breakers, if they detect a ground fault, they'll trip immediately to save you from electric shocks.

Outlets are another common issue with inverter generators, and if there's a problem with them, you won't have any power at the outlets.

The outlets in your generator are the main point of access to its power, and if they're damaged or have bad contacts, you won't be able to access the generator's power.

Here's a quick checklist to help you troubleshoot circuit breaker and outlet issues:

  • Circuit breaker tripped? Check if you've overloaded the circuit or if there's a ground fault.
  • Outlet not working? Check the contacts and wiring for damage.
  • Replace the circuit breaker if it's damaged or faulty.
  • Repair or replace the outlet if it's damaged or has bad contacts.
