Parallel Generators for Double the Power

For homeowners and professionals who require additional power flexibility, running generators in parallel provides an ideal solution. This method enables you to link two units together, achieving nearly double the power output without investing in a single, larger, and heavier machine. It's a smart workaround that lets you power larger loads, like RV air conditioners, with smaller, more portable units.

This guide walks you through the safe connection of two portable inverter generators for maximum results, along with essential compatibility and charging tips.

Why Run Generators in Parallel?

Today's demands for mobile power often exceed what a traditional portable generator was designed for. Running two inverter generators in parallel provides numerous benefits, making your power setup more flexible and efficient:

• Increased Power: You can significantly increase the available power to run larger appliances and systems, such as an RV's A/C unit.
• Lightweight and Portable: Transporting two smaller, lighter units is often easier than managing one massive generator.
• Extended Runtime: Running multiple generators in parallel often extends overall runtime.
• Fuel Efficiency: Inverter generators are already fuel-efficient, and many energy-efficient models vary throttle power during usage.
• Quiet Operation: Inverter technology ensures quiet operation, even when units are combined.

Understanding Compatibility and Safety

Before connecting any units, it's essential to ensure both safety and compatibility.

Generator Safety

Operating a generator improperly can be dangerous. Safety should always come first:

• Carbon Monoxide Danger: Generator exhaust contains odorless, invisible carbon monoxide. Never use a generator inside a home or garage, even if doors or windows are open.
• Outdoor Use Only: Generators should only be used outside, positioned far away from all windows, doors, and vents.
• Consult the Manual: Always refer to your generator owner's manual for safe and proper operation guidelines.

Compatibility Is Key

For safe and effective paralleling, your units must be compatible.

• Matching Units: The general rule is to only pair matching generators with the same amperage and voltage.
• Companion Units: Some brands, like Honda, require you to pair a standard unit with a specific companion model. Companion versions of these generators are designed specifically for parallel operation and feature a built-in 30-amp receptacle.
• Consult the Manual: Whether you can parallel two different inverter generators depends on the brand. Your owner's manual will state explicitly which generators a parallel kit can successfully connect.

Important: Avoid homemade workarounds to connect two generators that aren't designed to work together. Always follow the manufacturer's guidelines for safe operation.

How to Parallel Generators

The process of paralleling generators varies by brand, but generally requires two compatible inverter generators and parallel cables.

Can You Parallel Two Different Inverter Generators?

Whether you can parallel two different inverter generators depends on the brand. Generators designed for paralleling are perfectly safe as long as you follow the manufacturer's instructions, use the proper cables, and confirm that the units are compatible according to the manufacturer's specifications.

For some models, there may be no exclusive companion unit, but you can still parallel most inverter generators using parallel cables with a 30-amp outlet. These cables connect two of the same generators when a companion unit is not available. Be sure to only pair matching generators with the same amperage and voltage. Your owner's manual will specify which generators a parallel kit can successfully connect.

Avoid attempting homemade solutions to connect generators that aren't designed to work together. Always follow your owner's manual and manufacturer recommendations for safe operation.

Two Is Better Than One

Parallel generators let you enjoy all the benefits of inverter technology without worrying about limited power capacity. With the right setup, you'll have enough clean, reliable power to fuel your life—whether you're on the road, at a job site, or preparing for the next outage.
