Load Bank Test


In fact, a “Load Bank Test” is an integral part of a well-engineered preventive generator maintenance program and is part of the annual inspection to verify the UPS and generator capacity to support the power wattage load necessary without the hydro connection power supply. This is the optimal way to validate the performance of the “Emergency Generator System” in place as well as the functioning of the battery system to run the UPS System.

GenXpert specialists are on-site to test the load banks necessary and to avoid future damages or breakdowns. One of the key reasons the test is so critical and vital is that the Load Bank Test can vary the current conditions of the UPS batteries as well as battery sets to show whether any of the cells are holding on charge or reach the top of their lifespan duration and whether they are about to fail the system altogether.

This important preventive maintenance point will help you predict the replacements parts before they can cause serious damage to this critical application.

  • A Load Bank Test is often done after a week of installing a new commercial or industrial generator in operation,
  • A load Bank Test is most often used as a mandatory measure to assure that the full system has been tested and is in perfect conditions to support its purpose in the most critical time and place.
  • The inspection will be able to measure if the engine can provide the power required
  • It will definitely show the alternator capacity to provide and produce the required voltage stability necessary for the good function of the system
  • The assessment will be able to show the efficiency of all controls on the present system and how it will perform under different simulated conditions
  • The final report will be able to show the stability of the frequency it emits, the pressure of oil and fuel
  • Finally, the verification report will show the overall performance of the complete Load Bank System and all the recording of results from each test.
  • Some of the other benefits of the Load Bank Test are the removal of deposits from the pistons, and by removing engine castings, and exhaust that can show deterioration or weaknesses. You will also be able to predict the work and repairs that will need to be addressed in the future.


Load Bank Testing requires very specific equipment in order to fully test the capacity of a comprehensive generator system such as the load test equipment independent of the hydropower in place, must be able to produce the same level or higher of the wattage capacity required by the present system to run without electrical power. The load banks are available for both, AC and DC systems. It really all depends on the nature of the requirements. The best way to explain this is that DC systems are used to test batteries while an AC systems load block is used to test an entire UPS system. 

  1. Minimum load bank capacity of 100Kw
  2. Quality rated cables to facilitate effective charge transfer

The GenXpert portable load banks system is made up of heating elements and fans which are responsible for cooling the system. It will then help dissipate the reduce the noise during the testing process.

When carrying out the test, precise measurements are taken during discharge where the battery and system performances are determined and noted. GenXpert load bank test identifies the problems and list the immediate actions to take.

Load Bank Testing Equipment


 Types of clientele for which we do work for

  • Municipal Water Works Departments for their generators and pumping stations
  • Commercial and industrial buildings with “Fire Extinguishers” equipped with Generators
  • Nursing Homes, Retirement Homes and Group Homes with sprinkler systems linked to a generator source
  • Any organization commercial or industrial generators in place


Now that you know the importance of your generator equipment should be maintained, tested, and inspected regularly, Load Bank Testing should be carried out wisely and with the highest level of caution. This is why we are adamant about hiring experienced, skilled, professionals that have the proper equipment in place to do these crucial inspections and evaluations.

This type of testing represents a high risk for the specialist performing the test and the equipment in place that the analysis will be performed on.
