Portable Generator Load Bank Tester

If you’re concerned about the performance of your generator, a portable generator load bank tester is a smart solution. It helps verify that your generator is capable of running at full rated kilowatt output capability.

When your generator runs at higher kW loads, it increases the temperature and pressure within the engine, which removes unburned fuel and soot build-up. This results in increased engine performance and a longer service life.


A portable generator load bank tester is a tool that allows you to check the performance of a generator. It simulates a generator’s output by generating artificial loads using a configurable bank of resistive elements.

Load banks are a necessary part of testing power equipment like generators and Uninterruptible Power Supplies (UPS). They allow you to test the capabilities of these devices by putting them under varying load conditions.

They also help prevent wet stacking in diesel generators, which occurs when unburned fuel condenses with soot to create deposits in the exhaust system.

Lastly, these tests help ensure that your generator can provide the right amount of electricity when needed. It also reduces long-term costs and environmental pollution.

A load bank generator test can be used to check the performance of any type of generator, including natural gas and diesel units. It can be used to check the generator’s engine, alternator, batteries and inverter circuits.


Load bank testing is an important step in ensuring your generator can perform properly when it’s needed during an emergency. It ensures that the genset will be able to run at full rated capacity when the power goes out and can handle the load for the time it takes to restore the power to your facility or operation.

Using a load bank tester can help you avoid problems and issues that could be expensive to fix later on, like wet stacking and carbon deposits in the engine parts. It also helps to verify the genset’s cooling systems will work correctly when it’s under a lot of stress.

There are several types of load banks that can be used to test different generators and power sources. Some of these are permanent on-site or mobile to suit your needs.


A portable generator load bank tester is an easy to install device that can help you test your generator’s capacity at full kilowatt output (kW). It can also be used as a diagnostic tool for sales, showing potential customers how much power the generator will provide.

Load testing is essential to ensure your generator will be able to work when you need it. Performing regular load bank tests is the most accurate way to find out whether your generator will perform as designed.

This type of testing is generally required for emergency generators and systems that supply power to live-preserving equipment. This includes hospitals and healthcare facilities that use emergency power supplies to ventilators, monitors, and other machinery that keeps patients healthy during an outage of utility service.

Load bank testing should be carried out yearly or every three years, depending on your facility’s building load. This is a critical part of the safety and compliance process in accordance with the National Fire Protection Association standards, NFPA 110 and life-safety regulations.


Generators are used for backup power and rely on planned maintenance to keep them running at peak performance. These systems need to be inspected regularly for wear, rust and other issues that can cause them to fail when you need them most.

Portable generator load bank testers are a key part of this maintenance process. They are installed at your facility or job site to provide a stress test on your equipment that will verify its ability to perform during a power outage.

Load bank testing consists of placing the generator under artificial load to see if it can produce the maximum rated power. This allows you to have peace of mind that your generator can produce the power it needs when it is needed most.
