2 Product Overview
Product Introduction
Function
The Tesseract 5K14 is a single-phase grid-connected PV string inverter
and energy storage system. It can store the DC power generated by the
PV string into the battery, or convert the DC power generated by the PV
string or the stored energy of the battery into AC power. Power is input to
the grid.
Networking Application
The Tesseract 5K14 applies to a residential rooftop grid-tied system.
Typically, a grid-tied system consists of the PV string, grid-tied inverter,
AC switch, and power distribution unit.

Supported Power Grid
Power grid types supported by the Tesseract 5K14 include TN-S, TN-C,
TN-C-S, and TT. In a TT power grid, the N-PE voltage should be lower
than 30 V.

3 Storage
The following requirements should be met when the Tesseract 5K14
needs to be stored prior to installation:
•Do not unpack the Tesseract 5K14.
•Keep the storage temperature at -40°C to +70°C and the humidity at
5%–95% RH.
•The Tesseract 5K14 should be stored in a clean and dry place, and
be protected from dust and water vapour corrosion.
•A maximum of two Tesseract 5K14s can be stacked. To avoid
personal injury or device damage, stack Tesseract 5K14s with
caution to prevent them from falling over.
•Regular inspection is required during the storage. Replace the
packing materials when necessary.
•After long-term storage, an inspection and test conducted by
qualified persons are necessary before the Tesseract 5K14 is put
into use.

4 System Installation
Pre-Installation Check
Outer Packing Materials
Before unpacking the Tesseract 5K14, check the outer packing materials
for damage, such as holes and cracks, and check the Tesseract 5K14
model. If any damage is found or the Tesseract 5K14 model is not what

Determining the Installation Position
Basic Requirements
•The Tesseract 5K14 is protected to IP54 and can be installed
indoors or outdoors.
•Do not install the Tesseract 5K14 in a place where a person can be
easy to come into contact with its enclosure and heat sinks, because
these parts are extremely hot during operation.
•Do not install the Tesseract 5K14 in areas with flammable or
explosive materials.
•Do not install the Tesseract 5K14 in a place within reach of children.
•The Tesseract 5K14 will be corroded in salt areas, and the salt
corrosion may cause fire. Do not install the Tesseract 5K14 outdoors
in salt areas. A salt area refers to the region within 500 metres from
the coast or prone to sea breeze. The regions prone to sea breeze
vary depending on weather conditions (such as typhoons and
monsoons) or terrains (such as dams and hills).
Installation Environment Requirements
•The Tesseract 5K14 must be installed in a well-ventilated
environment to ensure good heat dissipation.
•When installed under direct sunlight, performance de-rate may be
initiated due to additional temperature rise.
•Install the Tesseract 5K14 in a sheltered place or install an awning
over the Tesseract 5K14.
Mounting Structure Requirements
•The mounting structure where the Tesseract 5K14 is installed must
be fireproof.
•Do not install the Tesseract 5K14 on flammable building materials.
•Ensure that the installation surface is solid enough to bear the
weight load.
•In residential areas, do not install the Tesseract 5K14 on drywalls or
walls made of similar materials which have a weak sound insulation
performance because the noise generated by the Tesseract 5K14 is
noticeable.
Installation Angle Requirements
The Tesseract 5K14 only can be wall-mounted. The installation angle
requirements are shown in Figure 4-1.
•Install the Tesseract 5K14 vertically.
•Do not install the Tesseract 5K14 at forward-tilted, back-tilted, side-
tilted, horizontal, or upside-down positions.

Figure 4-1 Installation angle
Installing the Mounting Bracket
There are four mounting brackets, which are installed through the
mounting brackets provided with the product.
Figure 4-2 Opening position plate

Wall-Mounted Installation
Procedure
Step 1 Use the hole positioning plate to confirm the position of the hole. Use a
bubble or digital level to adjust the position of the mounting holes and
mark the position with a marker.
Figure 4-3 Determining hole positions
Step 2 Install the expansion bolts.
Avoid drilling holes in the utility pipes and/or cables attached to back of the wall.
If the length or number of M8x80 expansion bolts supplied with the Tesseract 5K14 is
not enough, prepare M8 stainless steel expansion anchor bolts.
