so because the multiplus II kept thinking 48v was max SOC I ordered a shunt so I could manually tell it what its max voltage is
device auto updated without me even allowing it to do a update telling me I could not use the phone until update complete
but then the smart shunts not reading voltage correctly
voltage at the time was 51v . the negative voltage was when i disconnected the ve direct plug and reconnected
have tried on the main battery bank that has MPPT chargers and grid tied inverters connected to it , was reading over 600V
then tried a backup battery bank that is disconnected from other devices and still have 600V readings ???
I thought victrons meant to be quality hardware why is every part of this build being faced with issues ??
all that is connected is Red wire going to positive of battery and the Negative is connected to the shunt side opposite all the cables Grey/AUX is untouched , this is the water proof version with integrated cables
