Buying Guide: Key Factors To Consider
What size generator do you need? Choose based on essential loads (refrigeration, heating/cooling, lights, and communications) and any high-draw appliances you must keep running. For larger homes with HVAC systems, aim for 20 kW or more, and ensure the transfer switch matches your panel capacity.
What transfer switch and wiring are required? A properly sized transfer switch (16, 24, 48 or 200 Amp) determines how many circuits you can automatically switch. Ensure installation by a licensed electrician and alignment with local codes.
What fuel type works best? Gas and propane offer clean, reliable fuel; dual-fuel options provide backup if one fuel source is unavailable. Consider fuel availability and storage when choosing a model.
How important is remote monitoring? WiFi or cellular connectivity lets you track performance and receive alerts. If you travel or manage multiple properties, remote monitoring adds significant convenience and safety.
What about noise and footprint? Some units operate at lower RPMs to reduce noise. Review sound ratings and enclosure design, especially for installation near living areas or bedrooms.
What installation and warranty considerations exist? Look for units with robust warranties and support networks. Confirm that your electrical system and home’s panel support the transfer switch and generator capacity.
FAQ
- What is the difference between a standby generator and a portable generator? Standby generators are permanently installed with automatic transfer switches and full-house capability, while portable units require manual setup and are generally best for limited or temporary power needs.
- Do all standby generators require natural gas or propane? No. Some run on natural gas or propane, others require liquid fuel like gasoline, and some offer dual-fuel options for flexibility.
- Is cellular monitoring necessary? It’s not mandatory but adds convenience for remote status checks, maintenance alerts, and issue resolution, especially for long outages or multi-property setups.
- What maintenance is typical for standby generators? Regular oil changes, filter checks, battery maintenance, and periodic exercising tests are common. Follow the manufacturer’s maintenance schedule and have professional service as needed.
- Can I install a standby generator myself? Installing a standby system requires electrical, gas, and local permits. Work with a licensed professional to ensure safety and code compliance.
- What if I have a small home or apartment? A portable generator or a smaller, inverter-style standby system can cover essential loads. For full comfort and reliability, consider a higher-capacity standby unit if possible.
