3. Features
3.1. System connectivity
The control panel integrates with the inverter/charger system, consisting of a single or multiple Inverter/chargers configured as a
in stand-alone, parallel, and 2- or 3-phase system.
3.2. Power mode switch
The switch can be used to turn the inverter/charger system on, off or to charger-only mode.
3.3. LEDs
Eight LEDs replicate the inverter/charger LEDs.
Note that if the panel is connected to an inverter/charger model with only three LEDs, the full eight LED indications will be shown.
The LEDs auto-adjust to a lower brightness in low-light conditions.
3.4. Display
The 7-segment display primarily shows the AC input current and, if applicable, displays the AC input source or VE.Bus error
codes.
3.5. AC input control
The control panel's knob adjusts the AC input current limit. This is useful for mobile setups that connect to various AC sources
with different circuit breaker current ratings.
The adjustment range is synchronised with the inverter/charger system range. For instance, when connected to an inverter/
charger with 16A feed-through capacity, the AC input range remains within 16A. If linked to five of these units in parallel, it is
scaled up to 80A.
If an AC input range below the feed-through capacity of the inverter/charger is required, a custom upper threshold can be
configured. Refer to the Upper AC input limit 1 to 4 [7] chapter.
If needed, a fixed AC current can be specified in the inverter/charger settings, which then cannot be modified by the remote
panel. Refer to the Current limit overruled by remote [7] chapter.
3.6. Multiple AC inputs
The control panel automatically adapts to systems that have multiple AC inputs, as is the case with a Quattro or an extended
VE.Bus systems.
When switching between the different AC inputs, the display alternates between showing the AC current limit value and the input
name (AC2, AC3, etc.). For AC1, only the current limit will be shown.
The display remembers the last used AC current limit value for each input.
3.7. Generator support with external transfer switch
For a system with a MultiPlus together with an external transfer switch, the control panel can be configured to allow the AC
current to be changed while the system is connected to the grid but has a fixed AC current limit when connected to a generator.
The panel sends the current limit to the inverter/charger system as set via the knob. If the screw terminals on the panel's back are
short-circuited, a preset current limit is sent instead, and "GEN" is displayed.
To enable this, connect the screw connector terminals to an externally controlled switch, typically the auxiliary relay of an external
transfer switch. For setup, refer to the Generator current limit [7] chapter.
This feature is not relevant to a standard Quattro setup, which does not need an external transfer switch, and a fixed generator
AC input limit can be configured in the Quattro.
Digital Multi Control
Page 3 Features

4. System types
This chapter describes the different inverter/charger system types that the control panel can connect to.
4.1. MultiPlus system with 1 AC source
Setup is easy, simply connect the control panel to the VE.Bus system (refer to the Inverter/charger connection [5] chapter),
and it will automatically adapt to the system. No adjustments are required unless you want to restrict the operator's maximum AC
current setting. For this refer to the Upper AC input limit 1 to 4 [7] chapter.
4.2. Quattro system with 2 AC sources
If your system contains one or more Quattros, setup is easy. Simply connect the control panel to the VE.Bus system (refer to the
Inverter/charger connection [5] chapter), and it will automatically adapt to the system.
You probably will not need to adjust any settings in the control panel. In a Quattro setup, the AC1 input takes precedence over the
AC2 input. By default, the AC2 input current limit can be overridden by the remote panel, while the AC1 input current limit remains
fixed (this can be altered in the Quattro settings).
A common setup involves connecting a generator to the AC1 input and grid power to the AC2 input. While the generator runs, the
control panel shows "AC1," and the know can not alter the AC1 input current limit. Once the generator stops and shore power is
active, the panel toggles between "AC2" and the AC current value. Turning the knob will alter the AC2 input current limit.
To cap the maximum settable current, adjust the "Upper shore limit for AC input 2" parameter. For details, see the Upper AC input
limit 1 to 4 [7] chapter, and refer to the Special display feature [7] chapter to stop the display from toggling between "AC2"
and the AC input current value.
4.3. MultiPlus system with 2 AC sources and transfer switch
When using an external transfer switch (VE Transfer Switch) with a MultiPlus inverter/charger system, the switch dictates which
AC source is utilised - either generator or grid power. However, the control panel itself is not aware of the chosen AC source.
To ascertain the transfer status, the control panel features a screw connector on its backside. Normally, the panel sends the AC
current set point from the knob to the inverter/charger system. But, by short-circuiting the screw terminals, the panel displays
"GEN" and sends a preset AC current limit to the inverter/charger system.
For connection advice refer to the External transfer switch connection [5] chapter and for configuration instructions, refer to the
Generator current limit [7] chapter.
4.4. MultiPlus system with 2 AC sources
To create a system with multiple AC inputs, you can use multiple MultiPlus units and configure them as such, using the "VE.Bus
System Configurator" software tool. While such a system is feasible, it is advisable to first explore using Quattros. From the
control panel's perspective, building a system with Quattros or MultiPlus units does not make a difference. For further guidance,
refer to the Quattro system with 2 AC sources [4] subchapter.
Digital Multi Control
Page 4 System types

5. Installation
To install the control panel, you will need the following:
• Use an RJ45 UTP cable to connect the control panel to the inverter/charger. The cable is available in a variety of lengths (30cm
to 30m) and is not included with the control panel.
• If you are utilising the generator support [3] functionality, two wires are required to connect the control panel to the transfer
switch. Use wires with a thickness between 0.25 and 1.0mm². These wires are not included with the control panel.
5.1. Mounting
Use the four screws to mount the control panel as indicated below.
For control panel dimensions and mounting hole locations, refer to the Dimensions [13] chapter.
5.2. Inverter/charger connection
Use a regular straight UTP cable with RJ45 connectors to connect the control panel to the inverter/charger or the inverter/charger
system. If there are multiple units, connect the control panel to any unit with an available unused RJ45 port.
Note: In the case of a pre-VE.Bus multiple unit system, connect the control panel to the master unit.
5.3. External transfer switch connection
If an external transfer switch is used, connect its auxiliary relay to the screw connector terminals on the control panel's backside.
When the auxiliary relay is open, the AC current limit can be adjusted by the control panel knob. If the auxiliary relay is closed,
the control panel sends a preset generator AC current limit to the inverter/charger system. The auxiliary relay is controlled by the
external transfer switch.

6. Configuration
6.1. Setup menu
Configuration procedure:
• To enter the configuration mode, press the button on the back of the control panel for about 4 seconds until the bottom LED in
the right column starts blinking, indicating that the first parameter can be changed.
• To change the value of a parameter, turn the knob until the displayed value is as required.
• Press the configuration button to advance to the next parameter.
• Pressing the configuration button, after the last parameter is selected, will exit configuration mode and activate all parameters.
So even if only one parameter needs adjustment, you will have to go through all parameters.
• When the configuration button is pressed, or during configuration, the inverter/charger(s) will switch to "Inverter only" mode.
The lower three LEDs in the left column on the control panel indicate which parameter is being adjusted according to the table
below:
Menu item LEDs Parameter Default Range
1 Scaling factor 0 0 - 9
2 Generator current (A) 16 0 - 198
3 Upper AC current limit for AC1 input (A) 254 0 - 254
4 Upper AC current limit for AC2 input (A) 254 0 - 254
5 Upper AC current limit for AC3 input (A) 254 0 - 254
6 Upper AC current limit for AC4 input (A) 254 0 - 254
= LED is off, = LED is blinking, = LED is on
Digital Multi Control
Page 6 Configuration

6.2. Scaling factor
This parameter only applies to pre-VE.Bus systems. Leave it at its default value of 1 for VE.Bus systems.
For legacy pre-VE.Bus systems, refer to the Pre-VE.Bus scaling factor [11] chapter.
6.3. Generator current limit
This parameter only applies when an external transfer switch is used and has no impact otherwise.
The generator AC current limit can be adjusted within the range of 0 to 198A, with increments of 2A.
When configuring the generator AC current limit, be aware that not all generators can operate at full load. Particularly, smaller
3000 rpm generators from certain brands can overheat during extended full-load operation, and the maximum current should be
less than the rated maximum, while the AC current limit for 1500 rpm generators can be set higher.
• For 3000 rpm generators, set to 70% of their rated maximum.
• For 1500 rpm generators, set to 90% of their rated maximum.
6.4. Upper AC input limit 1 to 4
To prevent overly high AC input current limits, the control panel provides an upper AC input limit adjustment. For instance, when
dealing with large or multiple inverter/chargers working in parallel, the maximum feed-through current might exceed the AC supply
or circuit breaker capacity. Modifying the upper AC input current limit ensures the shore current limit remains within a specific
range.
An extended VE.Bus system can have up to four AC inputs. Yet, a basic VE.Bus MultiPlus system has one AC input. As such,
only the upper limit for AC input 1 needs to be configured. The other AC input limits can be safely ignored.
6.4.1. Special display feature
Consider this scenario:
You have an inverter/charger system with two AC inputs, namely generator and shore power. You want to prioritise the generator
over shore power. You connect the generator to AC input 1 and shore power to AC input 2. You do not want the user to alter
the generator AC input limit, so in the inverter/charger settings, you disable the "overruled by remote" setting for AC input 1, and
enable it for AC input 2.
The control panel will behave as follows:
• When the generator is active, the control panel displays "AC1".
• When the generator stopped and shore power is active, the panel alternates between displaying "AC2" and the current limit for
AC2. Yet, this alternating display might not match your preferences.
To resolve this:
A simpler approach is to show just the current limit value when AC input 2 is active. This is enough to indicate the switch to shore
power. To achieve this, set all but one of the upper AC input limit parameters to zero. In this example, the limits for AC1, AC3 and
AC4 should be set to zero. This adjustment eliminates the unwanted alternating behavior.
6.5. Current limit overruled by remote
This setting exists in the inverter/charger. When enabled, the control panel can modify the AC input current limit, and when
disabled, it can not.
In the case of a Quattro, both inputs have an "overruled by remote" setting and are independently configurable.
For details on configuring "overruled by remote," consult the inverter/charger manual.
6.6. Configuration example
Two examples are given to help you understand the setting of the parameters.
Two VE.Bus Multis 16A/230V + 4kVA gen. (3000 rpm) + external transfer switch.
Because this is a VE.Bus system, the scaling factor does not need to be set.
A 4kVA generator can supply a maximum current of 17.4A. Using a 70% safety margin, we will set the generator current to 12A.
To set the configuration, do the following:
Digital Multi Control
Page 7 Configuration

1. Press and hold the configuration button until the bottom LED in the left column starts flashing. This means you entered the
configuration mode, and you can change the scaling factor. As said, this parameter can be ignored in the case of VE.Bus
Multis.
2. Press the button to go to the next setting. The lower left LED will turn on, indicating that the generator current can be set.
3. Turn the knob until the display indicates 12.
4. Press the button to advance to the “Upper Shore limit for AC input 1” setting.
5. If you want the maximum shore current the operator can set to be lower than 32A, you can change this value.
6. Since the next 3 parameters (Upper Shore limit for AC input 2, 3 and 4) do not need to be configured, you can press the
button 4 times to step through the settings and finalise the configuration.

7. Operation
The control panel controls and monitors the inverter/charger system.
The control panel is active as soon as the inverter/charger system is switched on.
ID Description
A Charger LEDs: mains on, bulk, absorption and float.
B Light sensor, used to automatically dim the LED brightness.
C Inverter LEDs: inverter on, overload, low battery and temperature.
D Display, showing the AC input current limit, AC source or VE.Bus errors.
E AC current limiter knob, use to adjust the AC input current limit.
F On / off / charger-only switch, use to turn the inverter/charger on, off or to charger-only mode.
7.1. Turning the system on and off
Use the switch on the control panel to switch the system on, off or to charger-only operation.
7.2. Adjusting AC input current limit
Adjust the AC current limit using the control knob. The display shows the set limit, and in case of multiple AC inputs, the display
also shows the active AC input source (AC2, AC3, AC4).
When PowerAssist is enabled in the inverter/charger system, a minimum AC input current limit value applies. See the table below.
If set below this value, the inverter/charger stops charging, opens its internal transfer relay, disconnects from the AC supply and
starts inverting.
Current limits adjust in 0.5A steps under 10A, and 1A steps over 10A. For instance, an 11.1A limit rounds to 12A.
The control panel prevents setting a limit below the inverter/charger system's minimum AC current. If the AC input current limit
needs to be set to 0A (below the inverter/charger's limit), quickly turn the knob anticlockwise. The control panel display shows 0.0,
and the inverter/charger(s) will stop charging and start inverting. Turn clockwise to revert back to the minimum AC current limit.

*) The exact value depends on the inverter/charger model. Refer to the "Minimum input current limits" spreadsheet, located in the
"VE.Bus (Multies, Inverters and Quattros)" folder in the firmware section on the Victron Professional website.
7.3. LED brightness
For your comfort, the light sensor auto-adjusts LED brightness. As ambient light drops the LEDs dim to a more comfortable level
and save power.
Digital Multi Control

8. Backward compatibility with legacy pre-VE.Bus units
The control panel is backwards compatible with legacy (pre-VE.Bus) inverter/chargers running firmware versions 15xxyyy,
17xxyyy, and 18xxyyy. The transition from pre-VE.Bus to VE.Bus occurred from late 2007 to mid-2008.
For pre-VE.Bus systems, the control panel operation and setup align with the manual, except that the control panel does not
automatically adapt to the system. The default setting is for a standalone inverter/charger with a 16A transfer switch, but if a
different AC transfer current applies, the Scaling factor [7] needs to be adjusted.
8.1. System examples pre-VE.Bus
Pre-VE.Bus system with 1 AC source:
The control panel must be scaled (matched to the system) when it is used with pre-VE.Bus systems. This can be done by
changing the “scaling factor” parameter. For instructions, refer to the Scaling factor [7] chapter.
Once the scaling is accurately configured, proceed to set up any other relevant parameters. For instructions, refer to the
Configuration [6] chapter.
Pre-VE.Bus system with 2 AC sources:
For a pre-VE.Bus system with 2 AC sources, an external transfer switch (VE Transfer Switch) is essential.
The control panel must be scaled (matched to the system) when it is used with pre-VE.Bus systems. This can be done by
changing the “scaling factor” parameter. For instructions refer to the Scaling factor [7] chapter.
Once the scaling factor is configured, follow the installation process similar to using a VE.Bus system with an external transfer
switch. Refer to the MultiPlus system with 2 AC sources and transfer switch [4] chapter for instructions.
8.2. Configuration
Configuration is the same as described in this manual, with the exception that a scaling factor needs to be set up.
To set up the scaling factor, see the next paragraph, and for configuration of the remaining parameters, see the Configuration [6]
chapter
8.2.1. Pre-VE.Bus scaling factor
This parameter only applies to pre-VE.Bus systems. Leave it at its default value of 1 for VE.Bus systems.
The scaling factor aligns the control panel AC current with the system AC current and is exclusive to pre-VE.Bus inverter/
chargers.
Begin by calculating the scaling factor as directed in this chapter. Afterwards, move on to configuring the scaling factor. For
guidance on configuration, consult the Setup menu [6] chapter.
Scaling factor formula:
Scaling factor = (NrOfDevices * DeviceType) - 1
• DeviceType: 1 = 16A unit, 2 = 30A unit.
•NrOfDevices: all units, including the master unit.
Examples:
• One 16A unit: Scaling factor is: (1 * 1) – 1 = 0
•Two 30A units in parallel: Scaling factor is: (2 * 2) – 1 = 3
• Four 30A units in parallel: Scaling factor is: (4 * 2) – 1 = 7
•Six 30A units in 3-phase (2 paralleled units per phase): Scaling factor is: (2 * 2) – 1 = 3
Important:
1. When configuring a non-zero scaling factor in the control panel, do not specify the number of slaves in the VEConfigure
software. Instead, set the slave count to zero.
2. In a split-phase or 3-phase setup, the NrOfDevices reflects the number of devices per phase. So for a 3-phase system
consisting of 6 units (2 per phase), the NrOfDevices is 2.
Digital Multi Control
Page 11
Backward compatibility with legacy pre-
VE.Bus units

8.2.2. Configuration example pre-VE.Bus
Four pre-VE.Bus Multis 30A/120V + 13kVA gen. (1500 rpm) + external transfer switch.
For this configuration, the scaling factor must be calculated. The NrOfDevices is 4, the DeviceType is 2, so the scaling factor is (4
x 2) – 1 = 7.
A 13kVA generator 120V can supply a maximum current of 108.3A. Using a 90% safety margin, we will set the generator current
to 98A.
To set the configuration, do the following:
1. Press and hold the configuration button until the bottom LED in the left column starts flashing. This means you entered the
configuration mode, and you can change the scaling factor.
2. Turn on the knob until the display indicates 7.
3. Press the button to go to the next setting. The lower left LED will turn on, indicating that the generator current can be set.
4. Turn on the knob until the display indicates 98.
5. Press the button to advance to the “Upper Shore limit for AC input 1” setting.
6. You probably want the maximum shore current the operator can set to be lower than 128A, so turn the knob until the display
indicates a proper maximum shore current.
7. Since the next 3 parameters (Upper Shore limit for AC input 2, 3 and 4) do not need to be configured, you can press the
button 4 times to step through the settings and finalise the configuration.
