Buying Guide for Generators to Power Medical Equipment
Reliable power output: Ensure the generator provides continuous running watts above the requirement of your medical devices. Consider peak wattage for startup surges, especially for equipment like oxygen concentrators or CPAP machines.
Clean and stable power: Opt for inverter generators or models with low Total Harmonic Distortion (THD) to prevent damage to sensitive electronics used in medical equipment.
Noise level: Low noise (<65 dBA) is recommended to maintain a peaceful environment, especially critical for home medical use.
Runtime and fuel type: Longer runtime reduces refuel frequency during outages. Dual fuel (gas and propane) generators offer flexibility in fuel choices, helpful during extended emergencies.
Safety features: Carbon monoxide sensors and auto shutoff prevent poisoning risks – a crucial feature for indoor or nearby operation.
Portability and weight: For mobile use or limited space, consider lighter units that still provide adequate power.
Remote start and control: Wireless remotes enhance convenience and allow operation from a safe distance, especially useful for immobile patients or quick startups.
Compatibility with transfer switch: Models ready for transfer switches allow easy integration with home electrical systems, ensuring seamless power transfer to critical circuits.
Parallel capability: Some inverter generators can connect in parallel to increase output, allowing you to scale power based on device needs.
