Smart battery connect shows low battery voltage

Hi so I have a smart battery protect installed between my bank and an inverter. The back shows almost full charge, however as soon as I turn the inverter on the batter protect shows the battery at 9.5 volts.


I can't seem to connect to the battery protect via Bluetooth unless it's throwing up am error warning so I can't check whether it's a fault with the inverter drawing too much or a fault with the SBP.


I have the positive on the bank going to the SBP in and the SPB out going to the inverter positive and then the negative from the inverter going back to the bank. The ground is connected to a ground spike.


Any help much appreciated!
