Amps. However, for lower C-Rate discharge current of C/10 Amps and lower, the battery
will be almost completely discharged when the alarm is sounded. Hence, if the C-Rate
discharge current is lower than C/5 Amps, the battery may have completely discharged
by the time the Low DC Input Alarm is sounded.
7.12 LOW DC INPUT VOLTAGE SHUT-DOWN IN INVERTERS
disconnect the battery to prevent further draining of the battery. If the load is not dis-
connected at this stage, the batteries will be drained further to a lower voltage and to a
completely discharged condition that is harmful for the battery and for the inverter.
Inverters are normally provided with a protection to shut down the output of the inverter
