UPS offline or online

when we charge AC180 with grid (silent mode) and with PV (about 250w) simultaneously, at the moment when there is no energy in the grid, does the inverter continue working without disconnection or does the UPS intervene for 20ms? Is UPS offline or online? Thank you

Once the grid is disconnected, the AC180 switches to battery power within 20ms.
It is offline UPS mode.

@aristotel yea as @BLUETTI said above, these units (as do 99% of so-gens on the market with an UPS/EPS option) feature an “offline UPS” in them.


One of our good friends Jeff Hagen did a solid video going into detail on all this and the different modes within some of the units. Check out his channel “WaveFormScience” over on youtube when you get a chance!
