150 percent current: 50E7
Minimum voltage band: 2000
// Output voltage in hexadecimal
Maximum voltage band: 2100
Battery 200 volts: 0198
// Battery voltage in hexadecimal
Battery bad: 0240
Battery shutdown: 0268
AC line A-B scale factor: 31030
// AC input line voltage scale factors in decimal
AC line B-C scale factor: 31030
