Multi will not switch over
to generator or mains
operation.

initiated when switched
on.

The charger does not
operate.
The charger does not
operate. 'Bulk Protection'
shown.
The battery is not
completely charged.
Cause
MultiPlus-II GX in inverter mode
Circuit breaker or fuse in the AC-in input is
open as a result of overload.
The battery voltage is excessively high or
too low. No voltage on DC connection.
The battery voltage is low.
The converter switches off because the
battery voltage is too low.
The converter load is higher than the
nominal load.
The converter is switched off due to
excessively high load.
The environmental temperature is high, or
the load is too high.
Low battery voltage and excessively high
load.
Ripple voltage on the DC connection
exceeds 1,5Vrms.
The inverter is switched off due to an
excessively high ripple voltage on the
input.
The AC input voltage or frequency is not
within the range set.
Circuit breaker or fuse in the AC-in input is
open as a result of overload.
The battery fuse has blown.
The distortion or the AC input voltage is
too large (generally generator supply).
MultiPlus-II GX is in 'Bulk protection' mode
thus, the maximum bulk charging time of
10 hours is exceeded. Such a long
charging time could indicate a system
error (e.g. a battery cell short-circuit).
Charging current excessively high,
causing premature absorption phase.
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
Solution
Remove overload or short circuit on AC-
out-1 or AC-out-2, and reset fuse/breaker.
Ensure that the battery voltage is within
the correct range.
Charge the battery or check the battery
connections.
Charge the battery or check the battery
connections.
Reduce the load.
Reduce the load.
Install the converter in cool and well-
ventilated environment, or reduce the load.
Charge the batteries, disconnect or reduce
the load, or install higher capacity batteries.
Fit shorter and/or thicker battery cables.
Check the battery cables and battery
connections. Check whether battery
capacity is sufficiently high, and increase
this if necessary.
Install batteries with a larger capacity. Fit
shorter and/or thicker battery cables, and
reset the inverter (switch off, and then on
again).
Ensure that the AC input is between
185VAC and 265VAC, and that the
frequency is within the range set (default
setting 45-65 Hz).
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-II GX. The standard
MultiPlus-II GX 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.
