I still cannot understand, why Victron switch off the AC Output, if the Batterie has problem, but still the Grid is available?
My full house is connected to an 3-Phase system and the full house run over the 3 Multiplus. If the DC Bus has some Problem, the full House will switch off because of the Voltage Ripple or Voltage minimum. This can happen at the beginning of an system to see how it works with the batteries!
So maybe BMS will switch off the DC Voltage!
BUT if there is an AC Input available, why the Multiplus cannot switch to the AC-Mode and just switch to the passthrough mode?
So house is off in this situation and grid is available make no sense for me!
