We have been supplied a MultiPlus 12/3000/120-50 and 2 x Lithium SuperPack 12,8V 100Ah, the system is all connected up (it's been set to the closest battery settings as marked on the side of the battery as the manual doesn't suggest anything specifically for LiFePO4 batteries), however the MultiPlus when connected to external 230v supply will not charge the batteries (just shows Mains On light) and the Invertor side does nothing other than flash low battery warning. The system also has a Victron Solar PV MPPT set LiFePO4 batteries and that seems to provide charge to the batteries. Can anyone advise what the issue may be with the MultiPlus?
Many Thanks
