6. Maintenance
The MultiPlus does not require specific maintenance. It will suffice to check all connections once a year. Avoid moisture and
oil/soot/vapours, and keep the device clean.
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. MultiPlus 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” 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).
