How to Choose the Right Generator Parallel Kit

Confirm Generator Compatibility

This is the most critical step. Parallel kits are not universally compatible. Most are designed for specific brands and models, often requiring two identical generators. For example, the Journeyman-Pro Inverter Generator Parallel Kit works exclusively with matching Honda EU-series models. Using an incompatible kit can cause low voltage, damage your generators, or harm connected equipment. Always double-check the manufacturer’s compatibility list before purchasing.

Determine Your Required Output

Parallel kits are rated for different amperages, which dictates the total power you can draw. A 30-amp kit is common for linking two 2000-watt class inverters, suitable for most RV appliances and power tools. For heavier loads, like running two RV air conditioners, a 50-amp kit like the Champion Power Equipment 50-Amp ParaLINK Parallel is necessary. Match the kit’s rating to your combined generator output and the demands of your equipment.

Evaluate Build Quality and Features

Look for durable construction that can handle outdoor use. Features like a braided nylon sleeve, copper wiring, and right-angle plugs for a low-profile connection add to longevity and safety. Some kits, such as the Generac 7118 Parallel Kit for GP2200i and GP2500i, include a storage compartment for cables. Others offer multiple outlet types, providing flexibility for different plugs. Consider where and how often you will use the kit to decide which features are worth the investment. For more essential gear, visit our main Generator Accessories hub.

Understand the Connection Type

There are two main types: simple parallel cables and complete connection kits. Cables, like the Generator Parallel Cables for Honda EU1000i, directly link two generators, and you plug your devices into one generator’s outlets. A full parallel kit has its own dedicated outlet panel, allowing you to draw the combined power from a central point. Kits are often more convenient and organized, especially for permanent RV setups or frequent job site use. Learn more about the generators they connect in our Inverter Generators category.

Frequently Asked Questions

Can I parallel two different generator models or brands?

Generally, no. Most parallel kits require two identical inverter generator models from the same brand. Connecting mismatched generators can lead to improper load sharing, voltage irregularities, and potential damage to the units or your connected electronics. Always use a kit specified for your exact generator models.

What can I power with two generators connected in parallel?

Parallel operation effectively doubles your available power. This allows you to run larger RV air conditioners, more power tools on a job site, or additional appliances during a home outage. A 50-amp parallel kit can often supply enough power to start and run two 15,000 BTU RV air conditioners simultaneously, which is a common upgrade for campers.

Do I need a special parallel kit for a 240-volt output?

Yes, standard 120V parallel kits will not produce 240V power. You need a specific 240V parallel kit designed for generators that support that feature, like the WEN 50-Amp 12000-Watt 240V Parallel Connection Kit. These are less common and are only compatible with select inverter generator models built for 240V parallel operation. For more on different generator types, see our Portable Generators resource.

How do I maintain and store my parallel kit?

Keep the cables clean and dry, and store them in a provided pouch or case to prevent damage to the plugs and wiring. Before each use, inspect the cables for any cuts, frays, or damage to the insulation. Ensure the plug prongs are straight and clean for a secure connection. Proper care ensures reliable performance and safety for many seasons.
