Generator and Light Tower Sourcing Guide for Power Solution Distributors

Matching Power Rating and Fuel Type to the Application

Generators are bought by power output, so sizing is the first decision. Diesel generators offer high power and durability for industrial and continuous duty; Gas Generators are quieter and cleaner for standby and residential; light towers provide mobile illumination for construction and events.

Guide buyers to the right kVA/kW rating using a sizing calculation — undersizing causes overload failures, while oversizing wastes fuel and money.

Duty Cycle, Runtime and the Specs That Decide Reliability

For continuous or standby use, buyers care about duty cycle (prime vs. standby), fuel tank runtime, and noise level (dB). A prime-rated generator runs continuously; a standby-rated unit only handles occasional outages.

• Prime vs. standby power rating
• Fuel tank capacity and runtime hours
• Noise level (dB) for residential/urban use
• Automatic transfer switch (ATS) compatibility

Water-Cooled vs. Air-Cooled and Build Quality

Water-cooled generators handle larger outputs and continuous duty with better temperature control; air-cooled units are simpler and cheaper for smaller standby needs. Build quality shows in the alternator, engine brand and enclosure — a weatherproof, corrosion-resistant enclosure extends outdoor lifespan.

Specify the engine and alternator brand in your order, since these are the two components that determine long-term reliability.

Certification, Compliance and Export Requirements

Generators face strict emissions and safety regulation. Require CE (EU), EPA/CARB (US emissions), and confirm voltage/frequency matches your market (50Hz vs 60Hz, 230V vs 120V). Diesel engines also need emissions documentation for many markets.

Tip: Confirm local grid frequency and voltage for every destination — a 50Hz generator sold into a 60Hz market is a costly mistake.

MOQ, Lead Time and the Rental/Project Opportunity

Generator MOQs vary by size — small portable units may start at dozens, while large industrial sets are built to order with 30–45 day lead times. Light Towers and generators are core rental-fleet and construction-project purchases.

Offer spare parts and service kits alongside units — they are high-margin and cement the relationship with rental and project buyers who need uptime.

Frequently Asked Questions

Diesel or gas generator — which should I stock?

Diesel offers higher power and durability for industrial and continuous duty. Gas is quieter and cleaner for standby and residential. Stock both to cover the full application range.

What is the difference between prime and standby rating?

Prime-rated generators run continuously as the primary power source, while standby-rated units only handle occasional outages. Always match the rating to the buyer's duty cycle.

What certifications do generators need?

Require CE for the EU, EPA/CARB for US emissions, and confirm voltage/frequency matches your market (50Hz vs 60Hz). Diesel engines also need emissions documentation.
