Poor battery connection.
The absorption voltage has been set to
an incorrect level (too low).
The float voltage has been set to an
incorrect level (too low).
The available charging time is too short
to fully charge the battery.
The absorption time is too short. For
adaptive charging this can be caused
by an extremely high charging current
with respect to battery capacity, so that
bulk time is insufficient.

Check this table for appropriate
measures in regard to this alarm
state.
Ensure that the AC input is between
185 VAC and 265 VAC, and that the
frequency is within the range set
(default setting 45-65Hz).
Remove overload or short circuit on
AC-out-1 or AC-out-2, and reset
fuse/breaker.
Replace the battery fuse.
Turn the settings WeakAC and
dynamic current limiter on.
Check your batteries.
NOTE:
You can reset the error mode by
switching off and back on the
MultiPlus.
The standard MultiPlus factory setting
of the "Bulk protection" mode is
switched on. The "Bulk protection"
mode can be switched off with help of
VEConfigure only.
Set the charging current to a level
between 0.1 and 0.2 times the battery
capacity.
Check the battery connections.
Set the absorption voltage to the
correct level.
Set the float voltage to the correct
level.
Select a longer charging time or
higher charging current.
Reduce the charging current or select
the 'fixed' charging characteristics.
Set the absorption voltage to the
correct level.
Set the float voltage to the correct
level.
Replace the battery.
Improve ventilation, install batteries
in a cooler environment, reduce the
charging current, and connect the
temperature sensor.
─
Install the battery in a cooler
environment
─
Reduce the charging current
─
Check whether one of the
battery cells has an internal
short circuit
Disconnect the temperature sensor
plug in the MultiPlus. If charging
functions correctly after
approximately 1 minute, the
temperature sensor should be
replaced.
