Generators

For a construction site with multiple tools operating simultaneously including circular saws (1500W), compressors (2000W), drills (800W), and lighting (500W), choose a 6000 to 8000W generator offering a 25% safety margin to prevent overload.

Recommended specifications:

• Power output: 6000–8000W for 3–5 tools running simultaneously

• Type: Standard gasoline for optimal cost-performance ratio

• Runtime: 10–16 hours with a 20–30 liter tank

• Mobility: Pneumatic wheels and ergonomic handles

Models with electric start simplify cold morning startups. Multiple 120V and 240V outlets allow simultaneous connection of various equipment. Brushless alternators require minimal maintenance.

Équipement Industriel Polar recommends DeWalt and Generac models for reliability in daily professional use.

Yes, inverter generators are strongly recommended for sensitive electronic equipment including computers, phones, audio systems, and electronic controllers.

Total harmonic distortion (THD) under 3% versus 5–10% for standard generators protects delicate components from surges and fluctuations that can damage circuits.

Critical inverter advantages:

• THD <3% protecting electronics versus 5–10% standard units

• Ultra-stable voltage ±1% versus ±5% standard units

• Protected applications: Computers, phones, medical systems, UPS units

• Bonus: 30–40% lower fuel consumption and quieter operation at 50–60 dB versus 65–75 dB

For robust tools such as saws, drills, and compressors that tolerate fluctuations, standard generators are sufficient, saving 30 to 50% of the cost.

For mobile offices, medical equipment, or modern homes with electronics, inverter models are essential to avoid costly damage. Televisions, WiFi routers, and security systems also require inverter-level stability.

Équipement Industriel Polar recommends evaluating the equipment to be powered for proper selection.

The runtime of a 5000W generator varies from 8 to 16 hours depending on applied load and tank capacity. At 50% load (2500W), typical runtime is 12 to 16 hours with a 20 to 25 liter tank.

Factors affecting runtime:

• 25% load: 14–18 hours excellent efficiency

• 50% load: 10–14 hours recommended optimal use

• 75% load: 8–12 hours higher consumption

• 100% load: 6–10 hours maximum consumption

Inverter models with Eco-Throttle technology adjust engine speed according to load, extending runtime by 30 to 40%. A 15 liter tank provides 6 to 10 hours, while a 25 liter tank offers 10 to 16 hours.

Ambient temperature also affects performance: engines operating at -20°C consume 10 to 15% more fuel. Plan refueling based on actual runtime at 60–75% load for continuous productivity.

Change engine oil every 50 to 100 hours of use or annually, whichever comes first. Replace air filters every 100 to 200 hours depending on dusty environments.

Clean or replace spark plugs every 200 hours to maintain reliable starting and optimal combustion.

Professional maintenance schedule:

• After first 20 hours: Critical initial oil change

• Every 50–100 hours: Regular oil change

• Every 100–200 hours: Replace air filter

• Every 200 hours: Check/replace spark plugs

• Annually or before storage: Fuel stabilization and tank draining

Use synthetic 10W-30 oils suitable for temperatures ranging from -30°C to +30°C. Fuel stabilizers are essential during winter storage of 3 to 6 months to prevent oxidation. Electric start batteries require quarterly recharging.

Inspect oil level, filter condition, and bolt tightness monthly. Typical lifespan ranges from 5,000 to 20,000 hours depending on maintenance rigor.

Portable generators are covered by a manufacturer warranty of 1 to 3 years depending on the brand, covering manufacturing and material defects.

Honda offers 3 years for residential use or 2 years for commercial use, DeWalt provides a 3-year parts and labor warranty, and Generac offers 2 to 5 years depending on the model.

Warranties exclude normal wear, consumables, and damage caused by improper maintenance.

Typical warranty coverage:

• Engines and alternators: 2–3 years for manufacturing defects

• Frame and components: 1–3 years depending on brand

• Exclusions: Oil, filters, spark plugs, damage due to negligence

• Équipement Industriel Polar policy: 30-day return on unused product

For warranty claims, keep proof of purchase and maintenance records demonstrating proper servicing. Documented oil changes and use of genuine parts are required. Damage caused by overload, contaminated fuel, or improper storage is excluded.
