Can Different Types Of Generators Work Together In Parallel?

Generator Compatibility and Safety Requirements

To work together in parallel, generators must have identical voltage, frequency, and phase configurations. Typically, this means matching generators with the same AC or DC output, and ensuring they are designed for parallel operation. Inverter-based generators, such as those with a sine wave output, are often more suitable for parallel operation due to their ability to synchronize with other inverters.

Installing a Parallel Kit

A parallel kit is required to connect multiple generators together safely and efficiently. This kit usually includes a control panel, load-sharing cables, and other necessary components. The control panel typically includes a voltage regulator, which enables generators to share the load and prevent overloading. A parallel kit can be purchased as a standalone unit or as part of a generator package. For example, the Generac PWRiQ2000 parallel kit allows two generators to operate in parallel with a maximum output of 4,000 watts.

Load Sharing and Monitoring

Load sharing between generators is typically achieved through a voltage regulator or a load-sharing controller. This allows each generator to share the load proportionally, ensuring that no single generator is overloaded. Monitoring the generators’ performance is also crucial, especially when operating in parallel. This can be achieved through a digital display on the control panel, which shows the output power, voltage, and frequency of each generator. Some parallel kits also include software for monitoring and control, such as the Generac PWRiQ2000’s smartphone app.
