13. 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.
13.1 General error indications
Problem
Cause
Solution
No output voltage on
AC-out-2.
MultiPlus-II GX in inverter mode
Multi will not switch over
to generator or mains
operation.
Circuit breaker or fuse in the AC-in input is
open as a result of overload.
Remove overload or short circuit on AC-
out-1 or AC-out-2, and reset fuse/breaker.
Inverter operation not
initiated when switched
on.
The battery voltage is excessively high or
too low. No voltage on DC connection.
Ensure that the battery voltage is within
the correct range.
'Low battery' The battery voltage is low.
Charge the battery or check the battery
connections.
'Low battery' (Shutdown)
The converter switches off because the
battery voltage is too low.
Charge the battery or check the battery
connections.
'Overload'
The converter load is higher than the
nominal load.
Reduce the load.
'Overload' (Shutdown)
The converter is switched off due to
excessively high load.
Reduce the load.
'Over Temperature'
The environmental temperature is high, or
the load is too high.
Install the converter in cool and well-
ventilated environment, or reduce the load.
'Low Bat V Overload'
(Shutdown)
Low battery voltage and excessively high
load.
Charge the batteries, disconnect or reduce
the load, or install higher capacity batteries.
Fit shorter and/or thicker battery cables.
'High DC Ripple'
Ripple voltage on the DC connection
exceeds 1,5Vrms.
Check the battery cables and battery
connections. Check whether battery
capacity is sufficiently high, and increase
this if necessary.
'DC Ripple Shutdown'
The inverter is switched off due to an
excessively high ripple voltage on the
input.
Install batteries with a larger capacity. Fit
shorter and/or thicker battery cables, and
reset the inverter (switch off, and then on
again).
The charger does not
operate.
The AC input voltage or frequency is not
within the range set.
Ensure that the AC input is between
185VAC and 265VAC, and that the
frequency is within the range set (default
setting 45-65 Hz).
Circuit breaker or fuse in the AC-in input is
open as a result of overload.
Remove overload or short circuit on AC-
out-1 or AC-out-2, and reset fuse/breaker.
The battery fuse has blown. Replace the battery fuse.
The distortion or the AC input voltage is
too large (generally generator supply).
Turn the settings WeakAC and dynamic
current limiter on.
The charger does not
operate. 'Bulk Protection'
shown.
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).
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.
The battery is not
completely charged.
Charging current excessively high,
causing premature absorption phase.
Set the charging current to a level between
0.1 and 0.2 times the battery capacity.
Poor battery connection. Check the battery connections.
The absorption voltage has been set to an
incorrect level (too low).
Set the absorption voltage to the correct
level.
The float voltage has been set to an
incorrect level (too low).
Set the float voltage to the correct level.
The available charging time is too short to
fully charge the battery.
Select a longer charging time or higher
charging current.
