CyberPower - Intelligent LCD Series 850VA Battery Back-Up System - Black

UPS operation with a generator is dependent on how well a generator will maintain the frequency (slew rate). If the power draw is changing rapidly and the generator output frequency is not stable enough for the UPS to sync with it, the UPS will go into battery mode and eventually shut down. Most newer generators do a better job of holding frequency stable, allowing the use of standard UPS. Older generators tend to be not as reliable. There is not a way to know whether the UPS will work or not without actually testing it. For fail safe operation, a UPS with a generator mode should be selected, but they are usually more expensive.

CyberPower System doesn’t recommend standard UPS for medical equipment. Its recommended you speak with the manufacturer of the bi pap to find out the size of a UPS you need and if its OK to use a standard UPS vs. using a UPS designed for patient vicinity areas.

Hello, We generally would not recommend use with a generator unless it is an inverter generator. If the generator is able to output a stable frequency, there should not be any issues with compatibility. Thank you for submitting your question!

Hello Steve, This unit is only available in black. Thank you for submitting your question!

Yes it can be used. We recommend keeping the wattage below 80% of the max load. Thank you for submitting your question!
