Sigineer Power carries a few Tesla Battery Inverters with voltage settings tailored for Tesla Model S and Model X battery modules.

Currently, for some models, the battery type selector position of “9” is customized with a special battery algorithm to work with Tesla Model S and Model X lithium-ion battery modules.

For our APC6048D, HP12048D, HP15048D 48Vdc models, that is

Low Battery Cut Off: 36Vdc
Low Battery Voltage Alarm/ Charger Activation: 37Vdc
Low Battery Cut Off Recovery: 47Vdc.
High Battery Voltage Alarm/ Charger Cut Off: 50.5Vdc
High Battery Cut Off: 51Vdc

For our APC6024D and APC6024DT 24Vdc model, that is

Low Battery Cut Off: 18Vdc
Low Battery Voltage Alarm/ Charger Activation: 18.5Vdc
Low Battery Cut Off Recovery: 23.5Vdc.
High Battery Voltage Alarm/ Charger Cut Off: 25.25Vdc
High Battery Cut Off: 25.5Vdc

For Sigineer Power’s HPS6048D and HPS12048D solar inverter chargers, the powerful CPU allows users to set up their own spec for Tesla modules and other lithium batteries.

The recommended spec is:

Low Battery Cut Off: 40Vdc (40-48Vdc resettable)
Solar/Battery  to Utility(DC to AC) transfer voltage:  44V ( 44-51.2Vdc resettable)
Utility to Solar/Battery(AC to DC) transfer voltage:  50V( 48-58Vdc resettable)
CV/Fload voltage : 50V (48-58.4V resettable)

Warning: The output of these units will be de-rated by about 10% when the battery voltage drops below the nominal cut off of 20V, 40V, and 80V.
