4.0 Troubleshooting
Problem
The input Make sure to measure
battery under- the battery voltage
voltage warning just before the
(E05) and/or E01 battery under-
shutdown alarm voltage shutdown in
(E01) occurs Battery (Inverter)
in advance mode occurs, and
even when the compare it with the
battery voltage corresponding voltage
seems to be threshold in the
OK. (Cont.) specifi cations table
(allow +/- 5% of
tolerance).
The E05 warning and
E01 shutdown alarm
occurs well in advance
due to the SdH
setting.

Possible Cause/
Condition
Solution
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
specifi ed.
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.
