7. ERROR INDICATIONS
Important note:
When the battery is completely discharged (battery voltage less than 10V / 20V or 40V), the Quattro will start charging
only when AC power is connected to AC-in-1.
For the Quattro to start charging when AC power is connected to AC-in-2, battery voltage must exceed 10V / 20V or
40V.
7.1 General 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.

Poor battery connection.
The absorption voltage has been set to an incorrect
level (too low).
The float voltage has been set to an incorrect level
(too low).
The available charging time is too short to fully charge
the battery.
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.
The battery is overcharged. The absorption voltage is set to an incorrect level
(too high).
The float voltage is set to an incorrect level (too
high).
Poor battery condition.
a long charging time could indicate a system error
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).
Check this table for appropriate measures in regard
to this alarm state.
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).
Remove overload or short circuit on AC-out-1 or AC-
out-2, and reset fuse/breaker.
Replace the battery fuse.
Turn the settings WeakAC and dynamic current limiter
on.
Check your batteries.
NOTE: You can reset the error mode by switching off and
back on the MultiPlus.
The standard MultiPlus factory setting of the "Bulk
protection" mode is switched on. The "Bulk protection"
mode can be switched off with help of VEConfigure only.
Set the charging current to a level between 0.1 and 0.2
times the battery capacity.
Check the battery connections.
Set the absorption voltage to the correct level.
Set the float voltage to the correct level.
Select a longer charging time or higher charging
current.
Reduce the charging current or select the 'fixed'
charging characteristics.
Set the absorption voltage to the correct level.
Set the float voltage to the correct level.
Replace the battery.
