7. Trouble Shooting Table

Proceed as follows for quick detection of common faults.
DC loads must be disconnected from the batteries and the AC loads must be disconnected from the inverter before the inverter
and/or battery charger is tested.
Consult your Victron Energy dealer if the fault cannot be resolved.

MultiPlus 2kVA 120V
Cause
The battery voltage is too high or too
low
Processor in no function-mode
Pre-alarm alt. 1. The DC input voltage
is low
Pre-alarm alt. 2. The ambient
temperature is too high
Pre-alarm alt. 3. The load on the
inverter is higher than the nominal load
Pre-alarm alt. 4. Voltage ripple on the
DC input exceeds 1.25Vrms
Pre-alarm alt. 5. Low battery voltage
and excessive load
The inverter did cut out following a pre-
alarm
The AC input voltage or frequency is
out of range
Incorrect charging current
A defective battery connection
The absorption voltage has been set to
an incorrect value
The float voltage has been set to an
incorrect value
The internal DC fuse is defective
The absorption voltage has been set to
an incorrect value
The float voltage has been set to an
incorrect value
A defective battery
The battery is too small
The battery is too hot
Alt. 1: Battery overtemperature (>
50°C)
Solution
Ensure that the battery voltage is within the
correct value.
Disconnect mains voltage. Switch front switch
off, wait 4 seconds.
Switch front switch on.
Charge the battery or check the battery
connections.
Place the inverter in a cool and well-ventilated
room, or reduce the load.
Reduce the load.
Check the battery cables and terminals.
Check the battery capacity; increase if
necessary.
Charge the batteries, reduce the load or install
batteries with a higher capacity. Use shorter
and/or thicker battery cables.
Check the table for the appropriate course of
action.
Ensure that the input voltage is between
185Vac and 265Vac, and that the frequency
matches the setting.
Set the charging current at between 0.1 and
0.2x battery capacity.
Check the battery terminals.
Adjust the absorption voltage to the correct
value.
Adjust the float voltage to the correct value.
Inverter is damaged.
Adjust the absorption voltage to the correct
value.
Adjust the float voltage to the correct value.
Replace the battery.
Reduce the charging current or use a battery
with a higher capacity.
Connect a temperature sensor.
• Allow battery to cool down
• Place battery in a cool environment
• Check for shorted cells
