I should mention im looking for a low voltage cut off of 37 volts

im currently using a sungold power 48v 10k inverter to power my house via solar and I have 12 24v tesla modules in a 2s 6p configuration for 48v, my issue is i cannot use about 35% of the battery bank as the inverter cutoff voltage is 40v is there a way to change this or maybe assemble a diy ...
