(Appendix) Holding Registers for Modbus Queries
These registers can be addressed as either holding registers [for example,
4x0002] or input registers [for example, 3x0002])

4x0002
Battery Status
0: Battery OK
1: Battery Low
2: Battery
Depleted
Has effect only during power failure (battery
discharge), "Battery low" usually comes
minutes before the UPS batteries are depleted
and it switches off

Battery Charge
0: Floating
1: Charging
2: Resting
3: Discharging
Most common situation is "floating" as a
constant state, however this depends on the
UPS topology
