This happens a lot. Your input power lines fluctuate a lot from time to time. You get lags and sags and spikes on the power line. The UPS is just telling you this. Nothing you can do about that. Your UPS is operating normally. You don't really want to put the UPS into bypass during one of these fluctuations do you?

Remove the front panel plastic cover where the batteries are located, then plug the two connectors together, restart the UPS, and it should be fine.

Alarm error #191 comes from a battery test, where batteries are put under load for 25 seconds. (If the alarm is unexpected, you might have enabled the periodic 30-day battery test.)

#191 is test failure for battery internal resistance. So, need to locate and replace the bad battery, then run the battery test manually. If batteries are good, make sure no battery connector is corroded or loose.

You can check the battery fuse or the charging fuse. If it's more then that it's going to be a very costly fix.
