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.
7.1 General error indications
Problem Cause Solution
No output voltage on
AC-out-2.
Quattro in inverter mode
Defective fuse F3 (see appendix A).
Remove overload or short circuit on AC-out-2 and
replace fuse F3 (16A).
Multi will not switch over to
generator or mains operation.
Thermal circuit breaker (TCB) in the
AC-in-1 or AC-in-2 input is open as a
result of overload.
Remove overload or short circuit on AC-out-1 or AC-
out-2, and press TCB for recovery (see appendix A,
position N and O)
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” LED flashes. The battery voltage is low. Charge the battery or check the battery connections.
“Low battery” LED lights. The converter switches off because the
battery voltage is too low.
Charge the battery or check the battery connections.
“Overload” LED flashes. The converter load is higher than the
nominal load.
Reduce the load.
“Overload” LED lights. The converter is switched off due to
excessively high load.
Reduce the load.
“Temperature” LED flashes or
lights.
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 battery” and “overload”
LEDs flash intermittently.
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.
“Low battery” and “overload”
LEDs flash simultaneously.
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.
“Low battery” and “overload”
LEDs light.
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).
One alarm LED lights and the
second flashes.
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.
Check this table for appropriate measures in regard
to this alarm state.
The AC input voltage or frequency is not
within the range set.
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).
Thermal circuit breaker (TCB) in the
AC-in-1 or AC-in-2 input is open.
Press TCB for recovery (see appendix A, position N
and O).
The battery fuse has blown. Replace the battery fuse.
The charger does not operate.
The distortion or the AC input voltage is too
large (generally generator supply).
Turn the settings WeakAC and dynamic current limiter
on.
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.
The battery is not completely
charged.
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.
Reduce the charging current or select the ‘fixed’
charging characteristics.
