Q & A
What is the purpose of disabling the beep function on the inverter?
-The beep function is disabled to avoid noise disturbance and to make the rest of the video clear to hear.
What is the significance of the electrical network being the same as home?
-It signifies that the electrical network has 230 volts between neutral and phase and 400 volts between phases, ensuring no differences in the network setup.
Why is it important to set up the inverter for a back wattage system?
-It is important for a back wattage system setup because it ensures that the battery does not feed back to the grid but instead powers the house with solar energy both day and night.
What does selecting the lithium battery option in the battery mode do?
-Selecting the lithium battery option configures the inverter to communicate with the battery via cable, managing the whole charging and discharging process.
Why is it necessary to uncheck all boxes under gen charge and grid charge?
-Unchecking these boxes ensures that the battery does not charge from the generator or the grid, which is necessary for a simple system setup.
What does the 'low battery restart' percentage value indicate?
-It indicates the point at which the inverter will charge the battery to at least 50% after it has been discharged.
Why is zero export to CT enabled in the system?
-Zero export to CT is enabled to prevent any excess power from being sent to the grid, ensuring that all energy is directed to the load port based on consumption.
What is the purpose of setting the zero export power to 500 watts?
-It ensures that the inverter always draws a minimum of 500 watts from the grid, acting as a buffer to prevent unintentional momentary feeding when consumption drops.
Why is the time of use table feature enabled?
-Enabling the time of use table feature allows the inverter to manage battery discharge in systems with reverse power, not just charge it.
What does the VDE 0410 setting in the grid settings represent?
-VDE 0410 represents the network setup, which is the same as a home electrical network, ensuring the inverter is set up correctly for the local grid.
Why is asymmetric phase feeding enabled in the advanced functions?

⚙️ Introduction to DIE Inverter Setup at the D Factory
Norby Babos, the technical manager at Solar Kit, introduces the video, where he demonstrates setting up a DIE inverter at the D Factory in Ningbo. The inverter is connected to a battery on a test wall. Upon turning it on, it beeps, indicating an issue. The video explains how to disable the beep function in the basic settings. Norby also provides an overview of the electrical network, which is similar to typical home settings (230V between neutral and phase, 400V between phases). He discusses the basic setup, assuming a back wattage system where energy is not fed back into the grid, but used for powering the house through solar energy both day and night. The video also details the communication between the inverter and battery and the battery settings for optimal performance, including charging and discharging protocols.
🔋 Battery and Grid Settings Overview
This section dives deeper into the inverter’s battery settings, including the lithium battery communication protocol, charging modes, and battery thresholds for shutdown and restart during grid and off-grid situations. Norby explains how the inverter manages power, including discharge and charging levels for different conditions, like power outages. The system’s load management is also discussed, with zero export settings ensuring no excess energy is sent to the grid. He describes how features like 'selling first' and 'max export power' determine how energy is handled, depending on grid connectivity and load requirements. Peak shaving and time-of-use table settings are explained, ensuring efficient energy use without overloading the grid. Default settings, including phase configuration and grid detection, are reviewed to ensure the inverter works seamlessly in a home setup.
🔧 Advanced Features and System Configuration
Norby provides an in-depth overview of advanced settings, such as asymmetric phase feeding, which allows the inverter to manage power distribution across different phases based on demand. He explains how these settings optimize system efficiency for homes with varying consumption across the three phases. The video touches on off-grid operation using 'signal island mode' to bond neutral and ground outputs. He mentions a feature for integrating wind turbines, currently unavailable due to pending firmware updates. Lastly, Norby introduces the parallel menu, which is necessary for managing multiple inverters in a system, where devices are configured as either master or slave, with their roles assigned accordingly. The setup of external current meters is also covered.
📲 Connecting and Configuring DIE Cloud for Monitoring
This segment guides viewers through the process of connecting the inverter to the DIE Cloud for remote monitoring. Norby shows how to use the DIE Cloud app to connect the device to the local Wi-Fi network by scanning the QR code of the inverter or its antenna.

Transcripts
hi everyone I'm Norby babos the
technical manager at solar kit in
today's video we'll be setting up a die
inverter what makes this unique is that
we're here in Ningbo at the D Factory
behind me you can see a small test wall
with this hybrid inverter connected to a
battery as you saw when we turn on the
inverter it immediately starts beeping
indicating there's an issue so let's fix
this first so we can hear the rest of
the video clearly normally you can find
the settings in the top right corner in
the basic settings we need to disable
the beep function so the inverter won't
make that noise basically it's important
to know that the electrical Network here
is the same as home
so we have 230 volts between neutral and
phase and 400 volts between phases so
there won't be any differences in the
network so the basic settings that we
have to go through and set up are
assuming a back wattage system where we
have a battery we can't feed back to the
grid we have to feed back asymmetrically
and we want to power the house with
solar energy both day and night so by
default in the battery
settings we have a 5.1 prob die battery
so that's because the inverter
communicates via cable so we can select
the lithium battery option here in the
battery mode
[Music]
[Music]
we select the lithium
check back to battery settings there's a
lot of menus underneath here actually
gen charge gen signal and grid charge
grid signal which tells you from the
generator if connected to it or or from
the mains to charge the battery
by default these are we don't want to do
these because we're just putting
together a relatively simple system so
here we need to uncheck all the
boxes to make sure the battery doesn't
charge from the generator or the grid
now the next menu item here is battery
settings lithium mode is the 0 0 this
basically tells you if you're
communicating with the battery via cable
then uh which protocol the inverter uses
to to communicate with the battery the
whole charging and discharging if we set
it correctly then it will tell us here
that we have a die type battery on it
and the percentage values underneath
this is shut down low battery restart
and this is are given as Factory values
now if we come up from the bottom the
50%
is value where if battery is discharged
then the inverter will then charge it to
at least 50% and then it'll just draw it
down before it touches It Low battery is
35% that's the value which is for Main's
operation so if you have a network it
will allow the battery to discharge up
to
35% and at that 35% it will turn it off
and start charging it to at least
50% shut down the 10% is the value when
we have a power outage or we're in off
grid and we don't have AC power it'll
let you discharge up to
10% the battery and then it will start
charging ing to 50 by default we don't
have to touch that it's set up just fine
system work
[Music]
mode we have a lot of things connected
to the inverter right now but let's
assume that our load Port is not
connected and we only have a simple grid
tide system so we have zero export to CT
enabled which means it will monitor the
pad loocks on the load port to ensure
they're being used and it won't send any
Excess power to the grid if we had
selling first enabled it would send all
the energy back to the grid it wouldn't
measure anything or care whether there's
any reverse power everything would just
go directly to the grid with zero export
to load enabled no energy will be sent
to the grid instead all the energy will
uh be directed to the load Port
depending on how much consumption we
have there we have zero export to CT
enabled and since our system has reverse
power
we don't check the solar cell option
this option is for when we can feed
excess energy back into the grid this is
not relevant for us
here the next menu maxel power is the
one that gives the power when uh we can
set the maximum amount of energy that
can be sent to the Grid on the AC side
this is a 12 kilowatt inverter so a
total of 12 KW can be sent back
obviously that if it were allowed to
back feed and next to that is zero
export power that's 020 that's in Watts
this is the minimum amount the inverter
we'll always draw from the grid to
ensure there's no feed in that um
there's no feed in acting as a small
buffer or reserve on the consumption
side this can be set up to a maximum of
500 watt so we can set it so that if our
power demands on the
consumption side change rapidly we all
always draw 500 WS from the grid this
gives the inverter enough time to adjust
and compensate for the fluctuations this
way we can prevent any unintentional
momentary feeding when the consumption
suddenly drops ensuring no excess energy
is accidentally sent back to the grid by
default this is set to 20 wats and the
manufacturer doesn't recommend changing
that they design and optimize the system
around this 20 W
setting it's only worth adjusting this
if you notice that some energy is a
tionally being fed back into the
grid the grid Peak shaving feature which
we don't need to use at the moment
allows us to set a limit on the amount
of energy that uh that can be drowned
from the grid this can also be limited
in Watts for example if we want to
ensure that no more than 5 KW are are
drawn from the grid then we would enter
5,000 WS into this setting this menu
point is checked off since we've set
everything up
the next page is time of use
table now by default if the time of use
table is not
checked the inverter can only charge the
battery as long as it's connected to the
grid but it can't discharge it if we
want to enable the feature to switch it
on obviously it's to discharge the
battery in systems with reverse power
not just charge it we need to check the
time of use table this allows us to
manage battery discharge by default the
factory settings for the battery value
here are set to
80% these configuring values specify how
much the system will discharge the
energy stored in the battery while also
protecting its longevity so in this case
it will allow the battery to discharge
up to 80% so it's worth adjusting this
to the 35% that was set in the battery
settings menu so here we'll just click
on the 80% value and start decreasing it
until it reaches the allowed limit it
will automatically stop at 35%
% because that is the preset limit for
the battery we'll lower these values
down to
35% and once we've got all the
percentages down to 35 we can save the
settings by checking the Box we don't
need to check the grid charge and
Generator boxes here as they specify
whether we want to charge the battery
from the Grid or the generator during
the specified time period at the moment
this is not an option for us so we don't
need to adjust anything else we just
need to Simply check the box in the menu
below we have all the days from Monday
to Sunday selected allowing us to use
the battery every day of the week this
setup is perfectly fine as it is and
ensures that the battery is available
for use at all times next menu item is
the grid settings it has automatically
detected the vde 4105 which is the same
network setup we have at home this is
what we need to set it to we have 50 HZ
and the phase type should be either 0
120 240 or 0 24010 it depends on how the
phase rotations are connected at the
specific Transformer where the house is
located so I would suggest that we leave
it at the default factory
settings if the system indicates off
grid and doesn't start we need to switch
to the other setting after that it
should work fine we won't be able to
determine in advance how the three
phases are connected with
truffle here at the grid level we need
to set
Ln to 230 volts meaning we have 230
volts between the neutral and the phase
between phase and the phase it should be
around 400 volts and this is what needs
to be set here and uh if everything is
set correctly here we can check this off
as well in the grid settings there are
many more options further down but we
don't need to change them by
default these settings are all
automatically configured with the grid
code so there's no need to adjust
anything in the grid settings after that
in the advanced
functions there's really only one thing
that's important for us at home the
asymmetric phase feeding this setting
allows the system to feed power back
asymmetrically based on the consumption
demand across the three phases rather
than symmetrically with an equal amount
on each phase so we enable the
asymmetric phase feeding and with a
check of the box it is already activated
the signal Island mode is necessary when
operating in off- Grid mode without the
connection to the main grid
in this case it will bond the neutral
and ground at the output it is advisable
to enable this feature when in such a
setup in the advanced functions there's
also the wind turbine option currently
this feature is not included in the
latest firmware of the new inverters
because the manufacturers are still
developing a small control box that will
be connected on the DC side to allow for
the integration of wind turbines once
this control box is available the wind
turbine option will be reintroduced in
the latest firmware updates at that
point it will be possible to connect a
wind turbine directly to the invert on
the DC side using this control box for
now since the control box is still under
development we won't go into this
feature and finally we have the parallel
menu if we have multiple inverters
connected in parallel we can enable this
feature here in this menu we specify
whether each device is a master or a
slave and assign its serial number
essentially the master inverter is set
as number one and then the subsequent
slave inverters are number 2 3 4 5 and
so on these settings need to be
configured accordingly
and here is the last function the X
meter for CT this option needs to be
checked if we are using an external
current meter such as a smart meter
instead of the factory clamps included
in the package in this case we need to
check this option and specify the make
of the smart meter we are using so
that's basically all we need to set up
in the advanced functions
menu uh we don't need to worry about the
Gen Port used for now because it's
connected but not currently in use we
also don't use the smart load output for
a simple grid tide system with reverse
power we don't need to adjust these
settings at all leaving them at the
default Factory values will ensure
everything works
perfectly now in this video we can begin
using the die Cloud for managing and
monitoring which will be fully
operational and available for use
starting around May so we open the
dcloud app on the phone and from this
point on you'll be be able to see the
phone screen to get a better idea of how
everything looks and works so we open
our dcloud interface at the top left
you'll see our company name and at the
bottom right there's some information
about the company and your user account
click on the three little lines at the
top right then select Wi-Fi
configuration to connect your device to
the local network
Wi-Fi now it's best to log into the app
while already connected to the local
Wi-Fi network doing so ensures a
smoother setup process because you won't
have to enter the Wi-Fi password twice
once you're on the network scan the QR
code of the inverter or its
antenna then press confirm to verify the
number displayed under
SN it will immediately recognize that
your phone is connected to the local
Wi-Fi network you just need
to enter the password for the local
Wi-Fi
network the logger's password will be on
the bottom of the logger
itself the serial number is on top and
the password is below it you just need
to enter the code that is printed on the
dongle
itself once we connect we immediately go
back to the die Cloud app Grant it all
the necessary permissions and allow it
to access the devices the app will then
guide us through the steps to connect
the logger to
the local Wi-Fi network if this process
is
successful it will confirm the
connection indicating that our device is
now on Wi-Fi from there we can proceed
to create a site so we successfully
connected to the Wi-Fi from this point
on our device is online to create a new
site go back to the main menu click on
the three lines at the top right and
select create
plant it will then take you to the
screen where you can create a new
site it's a good idea to disconnect from
the inverter's wi-fi at this point since
it won't have much internet access
instead use your local Wi-Fi or mobile
network for a more reliable connection
for plant name we now enter D test
center it's very important to set the
correct time zone for the location if
you enter the wrong time zone this
mismatch will result in discrepancies
between the data and the actual time
accurate time settings ensure that the
monitoring do is synchronized correctly
with real-time events providing precise
and reliable
information
so this is important and
then for system
type select storage system because we
have a battery for insert capacity into
the amount of solar power on the roof in
kwp let's say it's 10 KW yes for
longitude and latitude enter the
coordinates it will fetch the necessary
details which should be accurate for our
needs we're at the die
Factory now it shows that our site has
been created but no logger is associated
with it yet so we click on ADD now and
scan the QR code of the logger we check
the SN to make sure it matches the one
on the
logger the last digit should be 884 and
if they match we confirm the system will
then add this logger to our site at this
point the site setup is complete with
the device integrated the final step is
to assign an end user to the site to do
this click on the three dots at the up
right corner of the screen select manage
access then go to authorize users here
click the plus sign and enter the email
address of the user you want to assign
this will grant them access to Monitor
and manage the
system once it finds the user we can add
them and choose their permission level
permission level only view can edit or
and manage for the end user only view is
usually sufficient for them to see the
site statistical data however if we want
to provide deeper access we can give
them full administrative rights allowing
them to manage the site from their phone
entirely this depends on individual
preferences and what access they need uh
by default only view is enough for most
users the can view option is more than
enough for users to check the
statistical data with this setup we have
successfully commissioned our inverter
created the site and added the user the
system is now fully operational this
covers the basic setup of the inverter
for a reverse power system with a
battery allowing a symmetric feeding to
only cover consumption without without
feeding energy back to the grid broadly
speaking I think we have covered all the
important
information
so if you have any questions feel free
to contact our team you can reach us by
phone and we're happy to assist with any
commissioning issues
so good luck with your die
system see you in the next video
