What to Look for in a Standby Generator System
Power Capacity and Load Management
Your first step is calculating your home’s essential wattage needs. Start by listing critical appliances like refrigerators, furnaces, well pumps, and medical equipment. A smaller 8.5-kW unit may suffice for essential circuits, while larger homes with central air conditioning require 20kW or more. Systems like the Generac Guardian 26kW Home Generator include True Power Technology for clean, stable electricity that protects sensitive electronics.
Consider future needs and potential load shedding features. Some advanced transfer switches can prioritize circuits, temporarily turning off non-essential loads to handle the surge of starting a large air conditioner. This smart management ensures your most important systems stay online. Our guide on the best automatic home standby generators dives deeper into capacity planning.
Fuel Source and Runtime
Your fuel choice impacts convenience, cost, and runtime. Natural gas offers an unlimited supply from your utility line, eliminating refueling worries. Liquid propane (LP) is a reliable alternative where natural gas isn’t available. For maximum flexibility, some models, like the WEN 14,500-Watt Tri-Fuel Generator, can run on gasoline, propane, or natural gas with a simple dial turn.
Runtime is crucial during extended outages. A permanently installed standby generator connected to a natural gas line or a large propane tank can run for days or weeks. Verify the system’s cold-weather performance, as some feature sub-zero start capabilities for reliable operation in harsh winters. This ensures your home stays protected no matter the season.
Automatic Transfer Switch (ATS) and Installation
The automatic transfer switch is the brains of the operation. It constantly monitors utility power and signals the generator to start within seconds of an outage. Look for a switch with an amperage rating matching your home’s main electrical panel, typically 200-amp for whole-house coverage. The switch included with systems like the Kohler 20RESCL-200SELS 20 is service entrance rated for professional, integrated installation.
Professional installation by a certified electrician is non-negotiable for safety and compliance with local codes. The installation complexity can vary; some newer systems feature technology that reduces wiring needs, potentially lowering costs. Enclosure durability is also key, with options ranging from corrosion-resistant aluminum, as seen in aluminum enclosure models, to robust steel construction highlighted in our steel enclosure review.
Smart Features and Warranty
Modern generators offer remote monitoring via Wi-Fi or cellular connectivity. With the Generac Guardian 14kW Home Generator, you can check status, receive maintenance alerts, and view historical data from your smartphone. This remote oversight provides tremendous peace of mind when you are away from home. Look for units with self-diagnostic tests that run weekly to confirm readiness.
A strong warranty reflects the manufacturer’s confidence. Coverage can range from 5 years on engines to 10-year limited warranties on complete systems. Factor in the availability of local authorized dealers for professional servicing. Robust warranty support ensures your investment is protected for the long term, making it a critical component of your buying decision.
Final Thoughts

Frequently Asked Questions
How does an automatic transfer switch work with a home standby generator?
An automatic transfer switch (ATS) is permanently wired between your utility meter and your home’s main electrical panel. It continuously monitors the incoming utility power. The moment it detects an outage, it sends a signal to start the generator. Once the generator is running at proper voltage, the ATS safely disconnects your home from the grid and connects it to the generator, all within seconds. When utility power is restored, it switches back and signals the generator to shut down.
What size home standby generator do I need for my house?
Sizing depends on what you want to power. Start by creating a list of essential circuits: refrigeration, heating system, well pump, sump pump, and a few lights and outlets. The total running wattage of these items determines your minimum capacity. For whole-house coverage, you must account for larger loads like central air conditioning. A professional installer can perform a detailed load calculation. Many homeowners find a 14kW to 22kW unit sufficient, but larger homes may require 26kW or more, especially if they want to maintain total normalcy during an outage.
Can I install a home standby generator myself, or do I need a professional?
Installation must be performed by a licensed electrician and often requires a certified plumber for gas line connections. The process involves high-voltage electrical work, connection to your home’s fuel supply, and compliance with strict national and local building codes (NEC, NFPA). Improper installation can be extremely dangerous, risk fire, void the manufacturer’s warranty, and invalidate your home insurance. Always use a qualified professional to ensure the system is safe, reliable, and legally compliant. For temporary power needs with easier setup, you might consider a portable generator as an alternative.
What is the typical maintenance required for a standby generator?
Modern standby generators are designed for low maintenance but are not maintenance-free. The most critical task is regular exercise: the system should automatically run a self-test for 5-20 minutes weekly to ensure all components are functional. You or a technician should check the oil level and change the oil and filter according to the manufacturer’s schedule, typically after the first 25-50 hours of operation and annually thereafter. The air filter and spark plug also need periodic inspection and replacement. An annual professional inspection is highly recommended to verify all systems, including the battery and transfer switch, are in optimal condition.
