A power outage isn’t just an inconvenience—it can shut down an entire operation, halt critical work, or put safety at risk. Whether you're managing a job site, running an event, or keeping essential services online, a reliable standby power source is non-negotiable. That’s where tow-behind standby generators shine. Built for mobility, durability, and performance, they provide on-demand electricity wherever it’s needed. But not all models are created equal.
Before making an investment, it’s crucial to understand key tow-behind generator features, how to go about choosing standby generators that fit your needs, and how to evaluate generator power output.
Let’s dive in.
The Must-Have Tow-Behind Generator Features
Shopping for a standby generator? Don’t just focus on wattage—functionality matters just as much. Here’s what to look for when assessing your options:
Portability That Goes the Distance
The whole point of a tow-behind generator is mobility, but that doesn’t mean every model is easy to transport. A proper unit should come equipped with a durable trailer frame, a secure hitch system, and robust tires designed for long hauls. If you’re planning to take it on the road frequently, check if the unit meets DOT (Department of Transportation) regulations—this ensures it’s safe for highway transport.
Fuel Type & Efficiency: What’s Under the Hood?
Tow-behind generators typically run on diesel, gasoline, or propane. Diesel models tend to dominate the industry because they’re fuel-efficient and built for longevity. However, gasoline units can be more accessible, while propane offers cleaner emissions and longer shelf life. Think about availability and operating costs before deciding.
Beyond fuel type, consider the tank size and runtime. Some generators can run for 24+ hours on a full tank, while others require frequent refueling. If you need long-term power, opt for a model with an extended fuel capacity.
Built Tough for Any Environment
If your generator can’t handle the elements, it’s not worth your money. Look for weather-resistant enclosures, corrosion-resistant coatings, and durable casings that can withstand harsh conditions. If noise levels matter (say, for residential backup power or events), a sound-attenuated enclosure is a game-changer, keeping operations quieter without compromising performance.
Smart Monitoring & Control Systems
A modern tow-behind generator isn’t just a hunk of metal and wires—it’s a precision machine. Many newer models feature digital control panels that allow you to track performance, fuel levels, and maintenance schedules in real-time. Even better? Some units come with remote monitoring capabilities, letting you check on generator status from anywhere via a smartphone or computer.
Choosing Standby Generators That Fit Your Needs
Finding the right generator isn’t just about buying the biggest or most expensive option—it’s about selecting the one that aligns with your specific power demands.
Power Needs: How Much is Enough?
Start by calculating the wattage of all essential equipment you’ll be running. Will it need to handle heavy machinery? HVAC systems? Sensitive electronics? Understanding total load requirements is key to choosing standby generators that won’t leave you short on power when it matters most.
Also, think about peak vs. continuous power. Some equipment, like pumps and compressors, requires a surge of power when starting up. Make sure your generator can handle those spikes without overloading.
Single-Phase or Three-Phase Power?
If you’re running a standard household or small business setup, a single-phase generator will likely do the job. But for industrial applications, large-scale construction projects, or data centers, a three-phase generator is the way to go. It provides a more stable power flow for high-demand systems.
Regulatory Compliance & Safety
Before making a final decision, ensure the generator meets safety and emissions regulations in your area. Many industries have strict compliance guidelines, and failing to adhere to them could result in hefty fines—or worse, an unreliable power source when you need it most.
Generator Power Output: Getting It Right
Understanding generator power output isn’t just about reading the kW label on the unit—it’s about knowing how that power translates into real-world use.
kW vs. kVA: What’s the Difference?
Generators are often rated in kilowatts (kW) and kilovolt-amperes (kVA). While kW represents actual usable power, kVA includes power lost in the conversion process. Most systems operate at a 0.8 power factor, meaning a 100 kVA generator delivers roughly 80 kW of real power. Understanding this distinction ensures you’re not underestimating your power needs.
Load Capacity & Run Time
Standby generators aren’t meant to run indefinitely, but the length of time they can operate depends on factors like fuel efficiency and load management. If you plan to use one for extended outages, ensure it has an adequate fuel tank, a reliable cooling system, and automatic shutdown features to prevent overheating.
Pairing Power with Visibility: Tow-Behind Generators + Light Towers
When power and visibility are both critical, pairing a tow-behind generator with portable light towers is a smart move. This combo is especially valuable on construction sites, at emergency response locations, and for nighttime events where reliable lighting is just as important as electrical power.
Why Light Towers and Tow-Behind Generators Work Well Together
Tow-behind generators offer the flexibility and output needed to power one or more light towers simultaneously. Here’s why this pairing makes sense:
On-site flexibility – Easily position both units exactly where power and lighting are needed
Plug-and-play compatibility – Most light towers connect directly to generator outlets
Shared mobility – Both systems are designed for transport, making setup and breakdown efficient
Centralized power – One high-capacity generator can run multiple towers, reducing clutter and cabling
Ideal for Challenging Environments
Whether it’s a late-night road repair job or an emergency staging area, this power-lighting combo delivers:
Enhanced safety through better visibility for workers and passersby
Increased productivity by enabling crews to work around the clock
Rapid deployment in disaster zones or remote areas with no existing infrastructure
If your job site or event requires both electricity and illumination, integrating portable light towers into your tow-behind generator setup ensures you're ready for anything—day or night.
Find the Right Generator Before You Need It
Power failures happen when you least expect them. That’s why choosing the right standby generator isn’t a decision to rush—it’s an investment in reliability, efficiency, and operational peace of mind.

FAQs
What size tow-behind generator do I need?
The size depends on the total wattage of the equipment you plan to run. A professional load assessment can help determine the right capacity.
Which fuel type is best for a tow-behind generator?
Diesel is the most common due to its efficiency and durability, but gasoline and propane are also viable options depending on your specific needs.
Can a tow-behind generator run an entire facility?
It depends on the facility’s total power requirements. Large industrial generators can handle entire buildings, but smaller units are best for targeted backup power.
How often should a standby generator be serviced?
Routine maintenance is essential, with checks typically required every 200-500 hours of operation. Regular oil changes, filter replacements, and inspections help ensure reliability.
Do I need an automatic transfer switch (ATS)?
If you want seamless power transfer during outages without manual intervention, an ATS is a must. It automatically switches power sources when the grid fails.
Can I use a tow-behind generator for residential backup power?
Yes, but ensure the generator meets local noise and emissions regulations. Proper installation by an electrician is also recommended for safe operation.
