Is It Possible To Combine Gas And Propane Generators In Parallel?

Choosing the Right Parallel Kit

To combine a gas and propane generator in parallel, you’ll need a generator parallel kit specifically designed for this application. These kits usually include a control panel, cables, and relays that allow you to synchronize the two generators. When selecting a parallel kit, ensure it’s compatible with both gas and propane generators, and check the voltage rating to ensure it matches the output of your generators. A popular choice for parallel kits is the Generac Parallel Kit, which supports up to 50 kW of combined power.

Synchronizing the Generators

Synchronizing your gas and propane generators in parallel requires careful attention to voltage, frequency, and phase. Start by setting the output of both generators to the same frequency (typically 50 or 60 Hz). Next, adjust the voltage of both generators to match within 1% of each other. Finally, use a phase meter to ensure the waveforms are in phase, then connect the generators in parallel using the parallel kit’s cables. Be cautious when working with high-voltage systems, and consider consulting a qualified electrician if you’re unsure.

Safety Precautions

When operating a gas and propane generator combination in parallel, safety is paramount. Ensure the generators are properly grounded, and follow the manufacturer’s guidelines for parallel operation. Regularly inspect the cables, connections, and control panel for signs of wear or damage. Additionally, consider installing a differential protector to prevent damage to the generators or the parallel kit in the event of a fault.
