Error Indications - Victron energy MultiPlus 12/3000/120 Manuel

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.

22
Cause
MultiPlus 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 1,5Vrms.
The inverter is switched off due
to an excessively high ripple
voltage on the input.
Solution
Remove overload or short
circuit on AC-out-1 or AC-out-
2, 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).
