If at any time during the battery discharge the input power becomes available again, contactors K1 and K5 close
and the rectifier begins to supply DC current to the converter and inverter. At this point, the unit returns to
Online mode. Depending on the total load and the duration of the battery discharge, battery current limit alarms
may be seen for a short time due to the current required to recharge the battery.
