Troubleshooting
F47 DC Under
Voltage
(Immediate)
Automatic Immediate battery
under voltage fault.
Check battery condition (short or open
cells) and ensure correct voltage.
Battery state charge or capacity is so
low that the DC voltage collapses
when inverter load is applied.
Inverter load is so large that the DC
voltage collapses when inverter load is
applied.
F48 DC Under
Voltage
(Fault)
Automatic Voltage at the DC
input terminals is
below the Low
Battery Cut Out
(LBCO) setting for 10
seconds.
Check for the correct battery voltage at
the inverter's DC input terminals.
Check for external DC loads on the
batteries.
Check condition of batteries and
recharge if necessary.
Reduce the Low Battery Cut Out
(LBCO) setting.
Battery bank capacity may be
inadequate for the loads in the system.
