1Introduction
This first section of this manual is intended to assist you in installing an AQ-Lith three-phase
battery storage system. It should only be installed by persons with a qualification in the field
of electricity and installation techniques.
The second part of the manual contains an extensive step-by-step plan for both connecting
the installation and setting the various devices and parameters. Furthermore, the second part
also contains an overview of the most common problems and their solutions.
Before installing a battery storage system, always check the conditions for a grid study and
the resulting additional safety measures.
The installer must always ensure that the contents of this manual
comply with the installation concerned and with the latest local
legislation such as the AREI, etc.
This manual is for support only. Following a training course
(recognised by us) is necessary for the correct installation and
commissioning of a battery storage system.
Be sure to refer to part 2 of the manual before starting to connect
and start up an installation. You will receive part two with the
purchase of your first installation.

5Installing the battery
The Energyrack is delivered in its entirety and therefore has a weight of more than 600 kg. So
check in advance how the battery can be moved to its place. If necessary, the modules (each
48 kg) can be removed to make it easier to move the battery. The battery itself is not wired
on arrival for safety reasons.
The inverters are best placed as close to the battery as possible to minimize cable losses. Hang
the inverters in a cool place because too high temperatures reduce the maximum power of
the inverters (see datasheet at the back). The MultiPlus -II GX must be placed in a dry and well-
ventilated room (IP21) and there must be at least 10 cm of free space around the device.
The local situation has a major influence on the additional material
required (cabling, additional power box, etc.) and therefore on the
installation cost. Keep this in mind when drawing up the total price.

6Connection diagrams: data and power cables
In this chapter some diagrams are given that are necessary when connecting this battery
storage system. Be sure to check whether a network study (or the associated additional
safety measures) is necessary. These are not included in the schedule!
These diagrams serve as an overview to clearly see the size of an installation. Before you
start connecting, you should carefully read the safety instructions for the battery and the
Victron Multiplus-II-GX.
These diagrams alone are not sufficient to correctly position and
connect the installation. Follow the step-by-step installation plan
(part 2) to avoid damage to battery and inverters.
The attached diagrams are principle diagrams. The installer is
responsible for choosing the correct safety components according
to the local application(s) and current legislation. Check whether a
grid study/decoupling relay is mandatory! (verg)
Circuit breakers may be installed with a nominal current other
than that indicated on the diagrams. 25A circuit breakers are best
chosen of type D.

1Introduction
This second part of this manual is intended to assist you in installing an AQ-Lith three-phase
battery storage system. It should only be installed by persons with a qualification in the field
of electricity and installation techniques.
This manual consists of three chapters:
1) Connecting the installation
2) Starting up and setting up the installation
3) Problems and Solutions
Also make sure to check in advance that you have the latest version of this manual.
The installer must always ensure that the contents of this manual
comply with the installation concerned and with the latest local
legislation such as the AREI, etc.
This manual is for support only. Following a training course
(recognised by us) is necessary for the correct installation and
commissioning of a battery storage system.
Be sure to consult part 1 of the manual before starting to connect
and start up an installation.

2Connecting the installation
With the help of the diagrams and the step-by-step plan that you can find in this chapter,
you are able to connect all devices and meters correctly.
2.1 hanging and placing appliances
The Victron Multiplus-II (GX) units should be hung on the wall. It is important to keep a free
space of at least 15 cm on all sides of these appliances so that the ventilation of the
appliances is not impeded. Never hang the inverters directly above the battery. Make sure
that the breakers protecting the inverters are not smaller than shown on the diagrams in
part 1.
The EnergyRack should be in a dry place with a constant temperature
(20-25°C) and out of the sun. Temperatures that are too high or too low can negatively affect
battery life and performance.
Try to keep the distance between the battery and inverters to a minimum to minimize any
cable losses.
The energy meter is placed just after the digital meter. Any Yuso controller may also be
placed on the wall near the inverter.
It is also possible to provide all the machines with which the inverters can be connected to
the grid at a later date. Do not connect the inverters to the grid yet!
2.2 Connecting the devices.
The wiring diagrams for connecting the power and data cables can be found in part 1 of this
manual. The first step here is connecting the EnergyRack internally. The schedule on the next
page can be followed.
When connecting the installation, the sequence (given in the step-
by-step plan) is MANDATORY to follow. If this is not done correctly,
damage may occur to the devices.
The Multiplus GX requires an internet connection via the cable.
Check beforehand that there are no security features that block
the access of the device to the network.

2.2.1 Wiring the EnergyRack
•Connect the dedicated CAN cable from the inverter to the master module (only use
the supplied cable)
•Place the dip switches according to the drawing above
•Connect the data cables between the different modules.
•Connect the power cables as indicated above, make sure that the long connection
cables are connected 'diagonally'.
