How to adjust Quattro to not turn off when my battery bank drops below 50%

I have a 12 volt system with LiPO4 batteries and a quattro 12 volt, 5000va, 220 amp invertor on my boat. The invertor shuts off and a low battery red light illuminates when the battery SOC gets below 50%. This coincides with a voltage of around 12.65v. My battery bank should be able to go a lot lower than that - probably safely down to 20% SOC and perhaps10.5volts?? How do I fix this?

You need to set the “DC input low shut-down”, restart and pre-alarm in the Quattro, as well as the low SOC shutdown if that is enabled.

If the unit is standalone you need a Mk3 to USB dongle or if you have a GX device you can do this via the internet. Use either of the options below, detailed instructions in the links.

  1. A smartphone using the VictronConnect app with a Mk3 USB interface between the phone and the Quattro.
  2. A PC/laptop using the VE Configure program with a Mk3 USB interface between the PC/laptop and the Quattro. I am not sure if VictronConnect on a PC/laptop can work like this or not, I believe it should but I have not used this method.
  3. A PC/laptop using the VE Configure program through a GX device if you have one connected to the Quattro and the internet. This is VE Remote Configure.
