How can I set the DC Input low shutdown lower than the default?

I have the Quarto 48v/5000 inverter with Tesla batteries configured at 48 volts. My Inverter shut off when I hit 37 volts, I believe. How can I set the DC Input low shut-down lower than 37.20 volts?20 volts?

@robmoors this is unfortunately not possible; this is one of the several reasons why Tesla batteries are non-supported, because their voltages are not common, ie a "48v" nominal Tesla battery bank runs much lower voltages than a common 48v nominal battery bank. In this case, a 20v shutdown would be rather low even for a 24v Quattro, let alone your 48v Quattro.
