Common Mistakes When Setting Up Parallel Generators — What Are They?

Inadequate Load Management

Setting up parallel generators requires careful management of the load to ensure that the total output matches the combined capacity of the generators. Failing to do so can cause overloading, which may lead to reduced efficiency, overheating, and damage to the generators. As a general rule, the load should not exceed 80% of the combined capacity of the generators to avoid overloading. For example, if two 20kW generators are running in parallel, the load should not exceed 16kW (20kW x 0.8) to ensure safe operation.

Incorrect Wiring

Incorrect wiring is another common mistake when setting up parallel generators. The wiring should be designed to handle the combined output of the generators and should be sized according to the manufacturer’s recommendations. Failing to follow proper wiring procedures can lead to electrical shock, equipment damage, and reduced efficiency. It is essential to use high-quality wiring and connectors that are designed for the application.

Mismatched Voltages and Frequencies

Mismatched voltages and frequencies are another common issue when setting up parallel generators. The generators should be matched in terms of voltage and frequency to ensure that they operate efficiently and safely. Failing to match the voltages and frequencies can lead to reduced efficiency, overheating, and equipment damage. It is essential to verify that the generators are matched in terms of voltage and frequency before connecting them in parallel.
