Buying Guide for Construction Generators
Power Output and Load Management
Calculate the total wattage required for all essential equipment that must run simultaneously. Include high-starting-wattage tools like air compressors and concrete mixers. A generator’s rated and surge capacity must exceed this total to prevent overloads.
Advanced models feature load-shedding technology, which prioritizes critical circuits during high demand. This intelligent management protects the generator and ensures vital systems remain online, a key feature for complex construction sites.
Durability and Environmental Protection
Construction environments are harsh. Look for generators with fully welded, corrosion-resistant enclosures. A 100% corrosion-proof design is essential for coastal sites or areas with extreme weather, protecting the internal components from dust, moisture, and salt spray.
Rugged construction and quality materials directly correlate with a unit’s lifespan and reduced downtime. Investing in a durable model from a reputable brand like Kohler pays dividends in long-term reliability. For the most heavy-duty applications, our review of the best Kohler industrial generators offers further insight.
Fuel Type and Runtime
Consider the most practical and available fuel source for your location. While gasoline is common, propane or natural gas models offer longer fuel stability and cleaner burns. Standby units that connect to a permanent fuel line provide uninterrupted power for extended outages.
Evaluate the generator’s fuel consumption at various load levels. Efficient engines not only lower operational costs but also allow for longer runtimes between refueling, which is crucial for overnight security or continuous pour operations.
Transfer Switch and Installation
A professional-grade automatic transfer switch is non-negotiable for standby power. It safely isolates the site from the utility grid and seamlessly switches to generator power. Ensure the switch’s amperage rating matches your site’s main service panel.
Always have installation performed by a certified electrician familiar with commercial and construction site codes. Proper installation ensures safety, compliance, and optimal performance. This is a key step for any commercial generator setup.
Final Thoughts
Securing reliable power is a foundational step for any successful construction project. For comprehensive whole-site protection, the Kohler 20RESCL-200SELS 20 offers robust power with a premium corrosion-proof enclosure. Remember, the longevity of any investment depends on proper care; the KOHLER Generators Maintenance Kit is a simple way to ensure your equipment delivers peak performance season after season, safeguarding your operational continuity.
Frequently Asked Questions
What size Kohler generator do I need for a construction site?
Size depends on your total connected load. List all motors, tools, and lighting, noting their starting and running watts. Choose a generator whose rated wattage exceeds the total running watts and whose surge capacity covers the highest starting wattage. Consulting with an electrician or a Kohler dealer is recommended for accurate sizing.
How often should I perform maintenance on a construction site generator?
Follow the manufacturer’s schedule strictly, typically found in the owner’s manual. For units in constant or heavy use, check oil levels daily and change oil and filters more frequently than standard recommendations. Regular maintenance, as outlined for all products in our brands section, is the most effective way to prevent unexpected failures.
Can a home standby generator be used on a construction site?
While the technology is similar, construction site generators are built for tougher environments. They often feature more robust enclosures, higher-duty-cycle engines, and connections designed for temporary power distribution. Using a residential model in a harsh construction setting may void the warranty and lead to premature failure.
Are there quiet Kohler generators suitable for noise-sensitive sites?
Yes. Many modern Kohler generators incorporate sound-dampening technology and quiet-test modes that run at lower RPMs during self-checks. Always check the decibel rating at specified distances. Proper placement and optional sound-attenuating enclosures can further reduce operational noise to meet local ordinances.
