I'm setting up a Multiplus Compact 12/1200/50 with a Smart LiFePo4 12.8V-160Ah.
Added a VE.BUS BMS Mains detector + VE.BUS MS (10R-05 4003) + digital multi control.
System comes right out of the box; should have been factory pre-programmed to work together.
When switching on with no 230VAC input and no load (no matter inverter or charge), the multiplus leds shows the charger-led on and hte alarm-led blinking. the digital multi control only shows the digits for amps (e.g. 16). When plugging in the 230VAC input, the digital multi control lights up the 'mains'.
I cannot find back the status of 'charge led on + alarm led blinking' in any of the manuals or the Victor led app. I prefer not to let the system be in that state without knowing what it means.
I measured the voltage of the battery and it is fixed 12.80V, no matter in with or without 230VAC input or state 'on/off/charger only'
