Are Generator Parallel Kits Universal?

Generators are a significant power source in multiple situations ranging from recreational activities to emergencies. However, the need to amplify this power supply has led to the invention of parallel kits. With these kits, it is possible to link two generators and effectively double the power output.

But the question arises, Are these parallel kits universal? Can you use one kit with any generator?

No, generator parallel kits are not universal. The kit should match the make and model of the generator for proper functioning and safety. Different brands of generators may have other electrical and mechanical characteristics that require specific parallel kits.

Generators and Parallel Kits

A generator is a device that converts mechanical energy into electrical energy, providing power when mains electricity is unavailable. Depending on their size and capacity, generators can supply power to anything from a single appliance to an entire home or facility.

A parallel kit, on the other hand, is an accessory that allows you to connect two similar or identical generators to increase power output. The kit combines the power from both generators into a single, stable stream. This concept may lead some people to believe that any generator can be connected with any other using a universal parallel kit.

Reasons Why Parallel Kits are Not Universal

Different brands and models of generators often have other electrical and mechanical properties. For instance, they may operate at different voltages, or their outlets might have different shapes and sizes. These variances necessitate specific parallel kits designed to match each generator’s characteristics.

For instance, a Honda generator’s parallel kit may not work with a Generac generator, even with similar power ratings. The outlets might not fit, or the electrical characteristics might be incompatible, leading to generator failure or damage.

Risks of Using a Non-compatible Parallel Kit

Using a parallel kit incompatible with your generator can result in various issues. At best, it simply won’t work. At worst, it can cause damage to your generator, pose a risk of electrical fires, or even harm the connected devices due to unstable power output. Ensuring compatibility is, therefore, not just a matter of convenience but also of safety.

How to Choose the Right Parallel Kit for Your Generator

Choosing the suitable parallel kit for your generator involves considering several factors. First, check the make and model of your generator. Most manufacturers provide specific parallel kits designed to work with their generators.

If you’re unsure which kit to choose, consult the generator’s user manual or contact the manufacturer’s customer support for guidance. Many manufacturers and retailers also provide resources, such as compatibility charts or online tools, to help you find a suitable kit.

FAQ on Are Generator Parallel Kits Universal?

Can you parallel non-inverter generators?

No, typically, you cannot parallel non-inverter generators. The primary reason is that non-inverter generators often don’t synchronize their power output efficiently, leading to power fluctuations and possible damage to the generators and the appliances they’re powering.

On the other hand, inverter generators are designed with built-in technology that allows them to produce a steady and clean flow of AC power at a consistent frequency. This technology also enables them to automatically synchronize their power output when connected in parallel, making it safe to increase total power output in this manner.

Can you parallel two different wattage generators?

It is not recommended to parallel two generators of different wattage ratings. The main reason is that generators of various capacities may not synchronize their outputs well, which could cause damage to the generators or connected devices.

When you parallel two generators, they need to be able to share the load equally. If one generator is more powerful, it could take on a higher gear, causing it to overheat or fail. This imbalance could also cause fluctuations in the power supply, which could harm sensitive electronics.

Inverter generators are often designed with parallel capabilities. Still, even then, using two identical models for the best and safest results is usually recommended. Always refer to the manufacturers’ guidelines when considering paralleling generators.

Can you parallel 3 generators?

Yes, it’s possible to parallel three generators. However, this generally applies to inverter generators and depends on the specific models and the parallel kit used.

Many inverter generators have parallel capabilities and can be linked using a special parallel kit that matches the brand and model of the generators. These kits typically allow for the paralleling of two generators. Still, some models and kits can link three or more generators together.

However, it’s essential to ensure that all generators are of the same model and have the same ratings for proper functioning and safety. Linking generators of different models or wattages can lead to problems, such as power imbalances or potential damage to the generators.

Always refer to the manufacturer’s instructions or consult a professional before attempting to parallel three generators. Proper synchronization and load balancing are critical; professional advice can help ensure you achieve this safely and effectively.

Can you parallel two different brand generators?

In general, it is not recommended to parallel two different brand generators. The main reason is that other brands can have different operating characteristics, voltage regulation, and protective systems.

Manufacturers design their generator parallel kits to work specifically with their own models. These kits are designed to match the electrical and mechanical characteristics of the generators, ensuring they work together seamlessly. Using two different brands could lead to synchronization issues, resulting in power fluctuations, system instability, or even damage to the generators or the devices connected.

Some advanced, aftermarket parallel kits claim to allow for paralleling generators of different brands or models. However, it is crucial to approach this cautiously, as the risk for potential issues is higher. It’s best to consult with a professional and follow the manufacturer’s recommendations.

Can you parallel a Honda 1000 and 2000 generator?

You cannot parallel a Honda EU1000i generator with a Honda EU2000i generator. Honda recommends paralleling two of the same or similar models for optimal performance and safety. While the technology in both generators may seem similar, the difference in power output and certain technical specifications between the EU1000i and the EU2000i models may need fixing.

This is due to how paralleling works; it requires both generators to share the load equally, and a mismatch in power output could lead to complications. Always follow the manufacturer’s guidelines when considering paralleling generators. If you’re unsure, it’s best to contact Honda or a professional for advice.


While the idea of a universal generator parallel kit might seem appealing, it’s clear that similar kits are not universal. Using the correct parallel kit is crucial to ensure efficient operation and safety.

Always check compatibility before purchasing and follow the manufacturer’s instructions to provide a successful and safe power amplification setup.

In the world of generators, the one-size-fits-all approach is not applicable, making careful selection and adherence to guidelines paramount.
