Once power is restored and stable, the unit will revert to on-line power and begin to rechange its' internal battery. It will drain its' internal battery pretty quickly if external power does not return fairly quickly (3 to 10 minutes or so, depending on your load draw).
Sorry, there was a problem. Please try again later.It reverts back to commercial power with a short time delay to allow for fluctuations in the incoming power. I have a whole house generator and as soon as it comes up and stabilizes this unit will switch back to it.
Sorry, there was a problem. Please try again later.The UPS will revert back to line mode from battery mode whenever wall power returns and meets the UPS's requirements for input power. You do not have to do anything to trigger this, it does so automatically if the outage does not completely drain the battery. Thank you for your question Lala!
