FAQs
How do I determine what size generator I need for my home or business?
Start by listing every appliance, tool, or system you need to power during an outage. Note each item’s running wattage and any additional starting (surge) wattage required. Add the highest surge wattage to the total running wattage to get a rough figure. Divide by 1,000 to convert watts to kilowatts (kW). Choose a generator with at least 10–20 % more capacity than your calculated load to avoid over-taxing the unit and to allow for future expansion.
What’s the difference between standby, portable, and inverter generators?
• Standby generators are permanently installed, start automatically during an outage, and run on natural gas or propane. They power an entire building or selected circuits and require professional installation. • Portable generators are movable units powered by gasoline, diesel, or propane. They must be manually started and connected, and are best for limited, temporary power needs. • Inverter generators produce cleaner, more stable electricity, making them ideal for sensitive electronics. They’re quieter and more fuel-efficient than standard portables but usually have lower output.
How often should I perform maintenance on my generator?
Follow the manufacturer’s schedule, but a good rule of thumb is every 6 months or 100 operating hours. Typical tasks include oil and filter changes, spark-plug inspections, air-filter cleaning or replacement, battery tests, and fuel-system checks. Standby generators usually run a weekly self-test, but they still require an annual professional service to ensure reliability.
What fuel options are available and how do they compare?
• Natural gas: Unlimited supply via utility lines, clean burning, lowest maintenance, but depends on municipal gas service. • Propane (LPG): Long shelf life and cleaner emissions than gasoline or diesel. Requires on-site tank and produces slightly less power per BTU. • Diesel: Highest energy density and better efficiency under heavy loads. Easier cold starts than gasoline but louder and emits more particulates. • Gasoline: Widely available and inexpensive units, but fuel degrades in 3–6 months and is less safe to store in large quantities.
How long can a generator safely run without interruption?
Runtime depends on the generator type, load, and fuel source. Portable gasoline units usually run 8–12 hours per tank. Diesel portables can reach 24 hours with a large fuel tank. Standby generators connected to natural gas can run indefinitely if properly serviced, but most manufacturers recommend shutting down for inspection after 200–300 continuous hours to prevent undue wear.
Do generators meet local noise and emissions regulations?
Modern generators are designed to comply with increasingly strict standards. Inverter units and many standby systems feature sound-attenuated enclosures, keeping noise as low as 50–65 dB (A) at 7 m (comparable to normal conversation). Emissions regulations vary by region (EPA, CARB, EU Stage V), so verify that the model you choose is certified for your jurisdiction. If additional mitigation is required, acoustic barriers, extended exhausts, or catalytic converters can be installed to meet local codes.
