7. Error Indications
With the procedures below, most errors can be quickly identified. If an error cannot be resolved, please refer to your Victron
Energy supplier.
We recommend to use the toolkit app to link LED alarm codes to a description of the problem/alarm, see

MultiPlus-II 12V/24V/48V 3kVA 120V
Cause
MultiPlus-II 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 1,5 Vrms.
The inverter is switched off due to
an excessively high ripple voltage
on the input.
The inverter is switched off due to
alarm activation by the lighted LED.
The flashing LED indicates that the
inverter was about to switch off due
to the related alarm.
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).
Solution
Remove overload or short circuit on AC-out-1 or AC-
out2, 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).
Check this table for appropriate measures in regard
to this alarm state.
Ensure that the AC input is between 97 VAC and
140 VAC, 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.
