Considerations for using home standby generators to power medical equipment

This article explains the differences between life-saving and non-life-saving medical equipment and how that impacts the choice of backup power. Generac residential home standby and portable generators can provide reliable power for many devices but are not designed to support equipment where a patient’s life depends on continuous operation. Customers who rely on critical medical devices should explore larger generator solutions or alternative backup options.

Disclaimer: Generac residential home standby and portable generators are not intended to power life-saving medical equipment. Customers who rely on such devices should consult with a licensed installer about alternative backup systems.

Considerations for using home standby generators to power medical equipment

While residential air-cooled home standby and portable generators provide reliable backup power during outages, they are not designed or intended to support life-saving medical equipment. Generac manufactures larger liquid-cooled and industrial generators for this purpose, but these products are typically used in large-scale facilities such as hospitals.

Qualifying the medical device

When evaluating medical equipment, such as nebulizers, CPAP, or dialysis machines, consider the following:

If the device is essential to life, a residential home standby or portable generator should not be used.
Does the device require low THD (total harmonic distortion) to operate successfully? Some Generac portable generators produce clean power while others do not. See What is Total Harmonic Distortion (THD)? and Which Generac portable generators have TruePower™ technology?
Note: Residential home standby generators produce clean power (THD < 5%). See Are Generac Home Standby Generators Safe to Power Sensitive Electronics?
The power needs of the medical device (in watts) and whether the generator can meet those demands. Be sure to account for starting watts in addition to running watts.
If the medical device must run continuously without interruption. In these cases, an uninterruptible power supply (UPS) may be required.

Examples of life-saving and non-life-saving medical equipment

Medical equipment categories

Life-saving equipment	Non-life-saving equipment
Ventilators (mechanical breathing support) Oxygen concentrators Dialysis machines Infusion pumps for critical medications Heart-lung bypass machines Defibrillators / ICD charging stations Medical suction machines	Nebulizers CPAP or BiPAP machines for sleep apnea Blood pressure monitors Blood glucose meters Powered mobility aids (wheelchairs, scooters) Heating pads and TENS units Adjustable hospital beds

Important: While some devices are generally classified as non-life-saving, their importance can vary by patient condition. For example, a CPAP may be life-critical for someone with severe sleep apnea.
