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
No output voltage on
AC-out-2.
MultiPlus will not switch
over to generator or
mains operation.
Inverter operation not
initiated when switched
on.
"Low battery" LED
flashes.
"Low battery" LED lights.
"Overload" LED flashes.
"Overload" LED lights.
"Temperature" LED
flashes or lights.
"Low battery" and
"overload" LEDs flash
intermittently.
"Low battery" and
"overload" LEDs flash
simultaneously.
"Low battery" and
"overload" LEDs light.
Cause
MultiPlus in inverter mode
Defective fuse F3 (see
appendix A).
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.
Solution
Remove overload or short
circuit on AC-out-2 and
replace fuse F3 (16A).
Remove overload or short
circuit on AC-out, 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).
