Buying Guide for Automatic Transfer Switches and ATS-Ready Portable Generators
When selecting an ATS or an ATS-ready portable generator, consider the following key factors to ensure a suitable and reliable power backup solution:
Power Capacity and Fuel Type
- Wattage Needs: Assess total wattage of devices or circuits to be powered during an outage. Choose a generator with enough starting and running watts to handle peak load.
- Fuel Flexibility: Tri-fuel (gasoline, propane, natural gas) or dual fuel generators increase versatility. Consider fuel availability and storage preferences.
ATS Compatibility and Safety Features
- Built-in or External ATS: Some generators have integrated ATS-ready outlets making connection easier. An ATS automatically transfers power to avoid manual delays.
- Safety Sensors: Look for built-in CO detectors and automatic shutoff features to protect against carbon monoxide poisoning.
Noise Levels and Portability
- Noise Output: Generators with inverter technology often produce noise levels under 65 dB, suitable for residential areas and camping.
- Mobility: Consider weight, handle design, and wheels for ease of transportation.
Remote and Ease of Use Features
- Remote Start: Enables convenient generator activation without exposure to harsh weather.
- Digital Displays: Real-time information on load, voltage, runtime, and fuel levels aid in monitoring performance.
- ECO Mode: Automatically optimizes engine speed to conserve fuel and reduce noise under light load.
Runtime and Fuel Efficiency
- Tank Size and Consumption: Larger fuel tanks and efficient engines extend runtime, reducing refueling frequency during emergencies.
- Energy Efficiency: Advanced generator technologies can lower fuel use and emissions for long-term savings and environmental benefits.
By thoroughly evaluating these aspects, you can select an ATS-linked portable generator that fits your specific backup power needs, offers safety and convenience, and ensures seamless power supply during critical outages.
