2. DESCRIPTION
SinusMax - Superior engineering
Developed for professional duty, this range of inverters is suitable for the widest range
of applications. The design criteria have been to produce a true sine wave inverter
with optimised efficiency but without compromise in performance. Employing hybrid
HF technology, the result is a top quality product with compact dimensions, light in
weight and capable of supplying power, problem-free, to any load.
Extra start-up power
A unique feature of the SinusMax technology is very high start-up power.
Conventional high frequency technology does not offer such extreme performance.
The inverters, however, are well suited to power up difficult loads such as
compressors, electric motors and similar appliances.
Virtually unlimited power thanks to parallel and 3-phase operation capability
Up to 6 inverters can operate in parallel to achieve higher power output. Six 24/3000
units, for example, will provide 18kVA output power. Operation in 3-phase
configuration is also possible.
To transfer the load to another AC source: the automatic transfer switch
If an automatic transfer switch is required, we recommend to using the MultiPlus or
Quattro instead. The switch is included in these products and the charger function of
the MultiPlus/Quattro can be disabled. Computers and other electronic equipment will
continue to operate without disruption because the MultiPlus/Quattro features a very
short switchover time (less than 20 milliseconds).
Programmable relay
The Inverter is equipped with a programmable relay, which by default is set as an
alarm relay. The relay can be programmed for all kinds of other applications however,
for example as a starter relay for a generating set.
Programmable with DIP switches or personal computer
The Inverter is supplied ready for use. The following features are available for
changing certain settings if desired:
─The most important settings can be changed in a very simple manner, using DIP
switches.
─All settings can be changed with a PC and free of charge software,
downloadable from our website www.victronenergy.com

3. OPERATION
3.1 On/Off Switch
When switched to "on", the product is fully functional. The inverter will come into
operation and the LED "inverter on" will light up.

4. INSTALLATION
This product may only be installed by a qualified electrical engineer.
4.1 Location
The product must be installed in a dry and well-ventilated area, as close as possible to
the batteries. There should be a clear space of at least 10cm around the appliance for
cooling.
Excessively high ambient temperature will result in the following:
•Reduced service life.
•Reduced peak capacity, or shutdown of the inverter.
Never position the appliance directly above the batteries.
The Inverter is suitable for wall mounting. For mounting purposes, a hook and two
holes are provided at the back of the casing (see appendix G). The device can be
fitted either horizontally or vertically. For optimal cooling, vertical fitting is preferred.
The interior of the product must remain accessible after installation.
Try to keep the distance between the product and the battery to a minimum in order to
minimize cable voltage losses.
For safety purposes, this product should be installed in a heat-resistant
environment. You should prevent the presence of e.g. chemicals, synthetic
components, curtains or other textiles, etc., in the immediate vicinity.

4.2 Connection of battery cables
In order to utilize the full capacity of the product, batteries with sufficient capacity and
battery cables with sufficient cross section should be used. See table.

Use a torque wrench with insulated box spanner in order to avoid shorting the
battery.
Maximum torque: 11 Nm
Avoid shorting the battery cables.
•Undo the four screws at the front of the enclosure and remove the front panel.
•Connect the battery cables: see Appendix A.
•Tighten the nuts well for minimal contact resistance.

EN Appendix
4.3 Connection of the AC cabling
This is a Safety Class I product (supplied with a protective grounding
terminal).
The neutral output of the inverter is connected to the enclusure.
This to ensure proper functioning of a GFCI (or RCCB) to be installed in the
AC output of the Inverter.
The chassis of the product must be connected to ground, or the frame (of a
vehicle) or the ground plate or hull (of a boat).
The terminal block can be found on the printed circuit board, see Appendix A. Use a
three-wire cable with a flexible core and a cross section of 2.5 or 4mm²
Procedure
The AC output cable can be connected directly to the terminal block "AC-out".
4.4 Optional Connections
A number of optional connections are possible:
4.4.1 Remote Control
The product can be remotely controlled in two ways.
- With an external switch (connection terminal H, see appendix A). Operates only if the
switch on the Inverter is set to “on”.
- With an Inverter Control panel (connected to one of the two RJ48 sockets C, see
appendix A). Operates only if the switch on the inverter is set to “on”.
Only one remote control can be connected, i.e. either a switch or a remote
control panel.
4.4.2. Programmable relay
The inverters are equipped with a multi-functional relay that by default is programmed
as an alarm relay. (VEConfigure software needed to change relay functionality).

4.4.3 Parallel Connection
The Inverter can be connected in parallel with several identical devices. To this end, a
connection is established between the devices by means of standard RJ45 UTP
cables. The system (Two or more Inverters plus optional control panel) will require
subsequent configuration (see Section 5).
In the event of connecting units in parallel, the following requirements must be met:
•A maximum of six units connected in parallel.
•Only identical devices with the same power ratings may be connected in parallel.
•Battery capacity should be sufficient.
•The DC connection cables to the devices must be of equal length and cross-
section.
•If a positive and a negative DC distribution point is used, the cross-section of the
connection between the batteries and the DC distribution point must at least
equal the sum of the required cross-sections of the connections between the
distribution point and the Inverter units.
•Place the units close to each other, but allow at least 10cm for ventilation
purposes under, above and beside the units.
•UTP cables must be connected directly from one unit to the other (and to the
remote panel). Connection/splitter boxes are not permitted.
•Only one remote control means (panel or switch) can be connected to the
system.
4.4.4 Three-phase operation
The Inverter can also be used in 3-phase wye (Y) configuration. To this end, a
connection between the devices is made by means of standard RJ45 UTP cables (the
same as for parallel operation). The system (Inverters plus an optional control panel)
will require subsequently configuration (see Section 5).
Pre-requisites: see Section 4.4.3.
Note: the Inverter is not suitable for 3-phase delta (Δ) configuration.

EN Appendix
5. CONFIGURATION
•Settings may only be changed by a qualified electrical engineer.
•Read the instructions thoroughly before implementing changes.
5.1 Standard settings: ready for use
On delivery, the Inverter is set to standard factory values. In general, these settings
are suitable fo stand-alone operation.
Standard factory settings
Inverter frequency 60Hz
Inverter voltage 120VAC
Stand-alone / parallel / 3-phase stand-alone
AES (Automatic Economy Switch) off
Programmable relay alarm function
5.2 Explanation of settings
Settings that are not self-explanatory are described briefly below. For further
information, please refer to the help files in the software configuration programs (see
Section 5.3).
Inverter frequency
Output frequency
Adjustability: 50Hz; 60Hz
Inverter voltage
Output voltage of the Inverter.
Adjustability: 95 –128V
Stand-alone / parallel operation / 2-3 phase setting
Using several devices, it is possible to:
•increase total inverter power (several devices in parallel)
•create a 3-phase system.
To this end, the devices must be mutually connected with RJ45 UTP cables.
Standard device settings, however, are such that each device operates in stand-alone
operation. Reconfiguration of the devices is therefore required.
AES (Automatic Economy Switch)
If this setting is turned ‘on’, the power consumption in no-load operation and with low
loads is decreased by approx. 20%, by slightly 'narrowing' the sinusoidal voltage.
The AES Mode can be set with a DIP switch.
Applicable in stand-alone configuration only.

Search Mode (Applicable in stand-alone configuration only)
If search mode is ‘on’, the power consumption in no-load operation is decreased by
approx. 70%. In this mode the inverter is switched off in case of no load or very low
load, and switches on every two seconds for a short period. If the output current
exceeds a set level, the inverter will continue to operate. If not, the inverter will shut
down again.
Not adjustable with DIP switches.
The Search Mode “shut down” and “remain on” load levels can be set with
VEConfigure.
The standard settings are:
Shut down: 40 Watt (linear load)
Turn on: 100 Watt (linear load)
Programmable relay
By default, the programmable relay is set as an alarm relay, i.e. the relay will de-
energise in the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the
input almost too high, battery voltage almost too low). Not adjustable with DIP
switches.
5.3 Configuration by computer
All settings can be changed by means of a computer.
The most common settings (including parallel and 3-phase operation) can be changed
by means of DIP switches (see Section 5.5).
NOTE:
This manual is intended for products with firmware xxxx400 or higher (with x
any number)
The firmware number can be found on the microprocessor, after removing the
front panel.
It is possible to update older units, as long as that same 7 digit number starts with
either 26 or 27. When it starts with 19 or 20 you have an old microprocessor and it is
not possible to update to 400 or higher.
For changing settings with the computer, the following is required:
- VEConfigure3 software. You can download the VEConfigure3 software free
of charge at www.victronenergy.com .
- A MK3-USB (VE.Bus to USB) interface.
Alternatively, the Interface MK2.2b (VE.Bus to RS232) can be used (RJ45
UTP cable needed).

EN Appendix
5.3.1 VE.Bus Quick Configure Setup
VE.Bus Quick Configure Setup is a software program with which systems with a
maximum of three Inverters (parallel or three phase operation) can be configured in a
simple manner. VEConfigure3 forms part of this program.
You can download the software free of charge at www.victronenergy.com .
5.3.2 VE.Bus System Configurator and dongle
For configuring advanced applications and/or systems with four or more Inverters,
VE.Bus System Configurator software must be used. You can download the
software at www.victronenergy.com . VEConfigure3 forms part of this program.
5.4 Configuration with DIP switches
A number of settings can be changed using DIP switches (see appendix A, position I).
Procedure:
•Turn the Inverter on, preferably unloaded.
•Set the DIP switches for:
oAES (Automatic Economy Switch)
oInverter voltage
oInverter frequency
•To store the settings after the required values have been set: press the 'Up'
button for 2 seconds (upper button to the right of the DIP switches, see
appendix A, position J).

Remarks:
- DIP switches ds8,ds7 ,ds6 ,ds2 and ds1 are not assigned and should remain off.
- The DIP switch functions are described in 'top to bottom' order. Since the uppermost
DIP switch has the highest number (8), descriptions start with the switch numbered 5.
- These settings are not relevant for slaves. They are however relevant for followers. If
you don’t want to bother about an Inverter being a master/slave/follower then the
easiest and most straight forward way is to set all settings identically on all Inverters.
5.4.1 AES (Automatic Economy Switch)
Procedure: set ds5 to the required value:
ds5
off = AES off
on = AES on
Note: The AES option is only effective if the unit is used ‘stand alone’.
5.4.2 Inverter voltage
Procedure: set ds4 to the required value:
ds4
off = 115V
on = 120V
5.4.3 Inverter frequency
Procedure: set ds3 to the required value:
ds3
off = 60Hz
on = 50Hz
5.4.4. Important note on ds2 and ds1
If the last 3 digits of the firmware is in the 100 range (so the firmware
number is xxxx1xx (with x any numer)) then ds1 & ds2 can be used to set
the inverter in stand-alone, parallel or three-phase. Please consult the
appropriate manual.

The overload and low-battery LEDs will flash to indicate acceptance of the
settings.
The DIP switches can be left in the selected positions, so that the ’other settings’ can
always be recovered.

6. MAINTENANCE
The Inverter 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.

state.

EN Appendix
7.2 VE.Bus LED indications
Inverters included in a VE.Bus system (a parallel or 3-phase arrangement) can
provide so-called VE.Bus LED indications. These LED indications can be subdivided
into two groups: OK codes and error codes.
7.2.1 VE.Bus OK codes
If the internal status of a device is in order but the device cannot yet be started
because one or more other devices in the system indicate an error status, the devices
that are in order will indicate an OK code. This facilitates error tracing in a VE.Bus
system, since devices not requiring attention are easily identified as such.
Important: OK codes will only be displayed if a device is not inverting!
•The "inverter on" LED must flash.
•A flashing "overload" LED indicates that the device can perform inverter
operation.
•A flashing "temperature" LED indicates that the device is not blocking
charge operation. (This is just a formal indication which originates from the
relationship with the Multi. This indication has no special meaning on an
Inverter)
NOTE: The "low battery" LED can function together with the OK code that indicates
that the device does not block charge.
7.2.2 VE.Bus error codes
If a VE.Bus error occurs (example: a broken UTP cable) the system will switch off and
the ‘inverter on’ LED will flash.
If such an error occurs one should switch all units off, verify all cabling and switch the
units on again.
Additional information about the errror can be retrieved from the Inverter with the
VE.BUS System Configurator or the VE.BUS Quick Configure tool.
