“I've read that this UPS, if the "sensitivity" is set to LOW, it will tolerate the "dirty power" that comes from a portable generator. How bad does the generator harmonic distortion have to get before the UPS complains or switches to battery mode?”

Thank you for your interest in our products. If you set the BN1500M2 to low sensitivity the UPS would support 78-142 volts without going to battery. It would also support 60 Hz ± 3 Hz without going to battery, given the voltage is within spec too.
Sorry, there was a problem. Please try again later.
