In this video,
we will show you how to connect the
Premium BYD Battery Box
to the KOSTAL PIKO MP plus and the KOSTAL
Smart Energy Meter.
Please note the information
relating to proper use.
Please first install the PIKO MP plus
and KOSTAL Smart Energy Meter.
You will find information relating to
this in the respective installation instructions
or in our explanatory videos.
You will also need the activation code
for the Smart Energy Meter's battery function.
You can get this code from the online
KOSTAL Solar Electric web shop.
Note: It is absolutely essential that the
Smart Energy Meter is installed at the
grid connection point
(position 2). When the battery input in
the PIKO MP plus is activated,
the installation position of the
KOSTAL Smart Energy Meter
is set permanently at the grid
connection point and cannot be changed!
During installation you will need
protective conductor cable
with cable shoo to fit, a network cable
for the communication connection between
the KOSTAL Smart Energy Meter and battery,
PV cable for the DC connection and a
pair of SUNCLIX plugs
from the inverter accessories as well as
an optional network cable
for connecting the battery to the internet.
Before getting started switch off any
components in your PV system that may
already be running.
Now check the communication connection
between the Smart Energy Meter
and the PIKO MP plus. If you have been
operating the two devices together for
some time before
and are only now retrofitting the
battery, you will need to change the
assignment of RS-485 plug "B"
on the Smart Energy Meter as shown.
Please also change the COM 2 connection to COM 1
on the PIKO MP plus. If this is a brand
new installation,
start with the new pin assignment in
connection to the Smart Energy Meter to COM 1.
Note: Deactivate the KOSTAL Smart
Energy Meter in the inverter settings if
it has been activated!
Please install the battery system as
outlined in the enclosed installation instructions.
Please note that none of the cables
between the KOSTAL Smart Energy Meter,
battery and PIKO MP plus may exceed a
length of 15 meters.
First align the base plate and position
the individual battery modules in
relation to one another.
Finish with the management module (BCU).
Screw the modules firmly to one another
and the wall.
Now guide the connection cables through
the cable glands provided on the
terminal compartment cover of the
management module.
Start by connecting the potential earth
cable of the battery
to the main earthing bus bar. Note: It is
absolutely essential that this
connection is made!
There must be no potential difference
between the PE connection of the PIKO MP plus
and the battery! Be particularly careful
to ensure that all cables are installed
and routed
in an EMC appropriate manner. Now connect
the communication cable to the KOSTAL
Smart Energy Meter at the battery's
terminal block connector.
Alternatively you can use the RJ45 socket.
Connect the other end of the cable to
the RS-485 connection "A"
(rear connection) on the Smart Energy Meter.
Note: We recommend using a network cable
category of 5e or higher.
Please ensure that the top and bottom
DIP switches are in the "on" position
and the middle switch is in the "off" position.
Connect your battery system to the
internet. When you do this,
the system transmits its operating data
to the manufacturer
so that support can be provided quickly
in the event of problems.
Available software updates can also be
downloaded.
To do this, connect the port labeled
"Ethernet" to your router or switch.
Now establish the DC connections. To
connect the PIKO MP plus
please use the pair of SUNCLIX plugs provided.
Now install the cover of the terminal
compartment and tighten the cable glands.
The system is now ready for commissioning.
First switch on the battery system by
using the fuses on the right hand side
of the housing.
The system starts the initialization process.
You now need to configure your battery
system. This can only be done using a
smartphone or tablet.
Download the "Be Connect" app from the Play
store or App store.
Connect with the battery's integrated
access point and launch the app.
This will first ask you to perform a
software update
and then guide you through the necessary
configuration process.
Please select "KOSTAL" as inverter, then
select the "HVS"
or "HVM" battery module and the number of
modules.
Select "on grid" and "single phase" and
confirm the settings.
Start by switching off the battery
system by pressing the power button
on the front for at least six seconds.
The DC connections in the PIKO MP plus
are configured as PV
inputs as standard. This means that the
DC input needs to be changed 
to battery operation.
To do this, first switch the AC supply on again.
Enter the inverter's main menu and use
the arrow keys to go to "Settings"
and then "Service".
Press the two arrow keys here at the
same time for a few seconds.
This opens the service menu. You can now
switch the DC input
to battery operation using the
menu item inputs.
The DC input is thereby switched to
battery operation.
Use the escape key to exit the menu.
Once you have confirmed the
configuration, the display shows
incorrect communication with the Smart
Energy Meter. This makes sense because the
battery functionality
first has to be configured in the 
Smart Energy Meter.
Now use the fuses on the right hand side
to switch on the battery system.
The system starts the initialization process.
Now open the KOSTAL Smart Energy
Meter's web server.
Do this by going to "Devices" in file
explorer on your PC
and accessing the Smart Energy Meter you
can see here.
First call up menu item "Modbus settings"
and deactivate both Modbus ports.
Save the settings.
Go to "Activation code" in the inverter menu
and enter the 10-digit battery code you
have been acquired.
The battery management field then
appears under "Released extra options".
In the devices area, add your PIKO MP plus
as a new device,
if this has not already been done.
Now configure the settings as follows:
Select the "PIKO MP plus" inverter type
and "RS485 B" as the interface.
The value of the PIKO MP plus is set for
"Maximum output power".
Enable battery support select "RS485 A"
as the battery's serial interface.
On request you can change the depth of discharge.
The value is present to 5%. 
"1" is used as standard
as the RS485 address.
Under "Status overview" you can now see
all the battery's values
including the charging status.
Your inverter and battery are shown in
the "Devices" menu.
Finish by moving the DC circuit switch
of your PIKO MP plus to the "on" position.
The inverter now launches on the grid
and you can use the battery.
If you want to display the yield,
consumption and battery data
in one system, the transmission of these
data to the Solar Portal
must be activated in the PIKO MP plus
and also in the KOSTAL Smart Energy Meter
Add both devices to the same plant in
the Solar Portal.
In the main menu of the PIKO MP plus, use
the arrow key to go to "Settings",
then "Network" and finally "Webportal".
Activate "Setup" to confirm data transmission. 
You can now use the "Connection test" menu
item to check communication with the Solar Portal.
In the KOSTAL Smart Energy Meter, go to
the "Inverter" menu
and the "Solar Portal" item to enable data export.
Don't forget to save the setting. Please
also note the KOSTAL explanatory videos
about how to set up the Solar Portal and
web server for our Smart Energy Meter.
