Solution
The input
battery under-
voltage warning
(E05) and/or
shutdown alarm
(E01) occurs
in advance
even when the
battery voltage
seems to be
OK. (Cont.)
Make sure to measure
the battery voltage
just before the
E01 battery under-
voltage shutdown in
Battery (Inverter)
mode occurs, and
compare it with the
corresponding voltage
threshold in the
speci
fi
cations table
(allow +/- 5% of
tolerance).
Just after the E01 occurs,
the battery voltage rapidly
increases since the battery
is not under a load condition
after the inverter shutdown.
This is normal in all the
battery banks and can
confuse the user thinking the
under-voltage shutdown that
triggers the E02 alarm occurs
in advance at higher voltage
thresholds than the ones
speci
fi
ed.
The E05 warning and
E01 shutdown alarm
occurs well in advance
due to the SdH
setting.
If you want to extend the run
time of the battery bank as
much as possible without the
need to keep enough battery
state of charge for engine
cranking purposes, make
sure to set the under-voltage
shutdown threshold to a low
values setting (SdL = factory
default setting) other than the
SdH.
