4.1 AC Detector for MultiPlus and Quattro (included in VE.Bus BMS delivery). Not needed for MultiPlus-II models.
The purpose of the AC Detector is to restart the MultiPlus or Quattro when AC supply becomes available, in case it has been
switched off by the BMS due to low cell voltage (so that it can recharge the battery).
Note 1: The AC Detector is not needed in case of an inverter.
Note 2: In systems consisting of several units configured for parallel, three phase or split phase operation, The AC Detector should be wired in the
master or leader unit only.
Note 3: The VE.Bus BMS assistant or the Self-consumption Hub-2 v2 assistant must be loaded in all units.
