2.0 Product Description
The PowerFlow Energy Gateway is a device designed to connect the Sundial battery storage
system to the internet via the building’s broadband connection. The Energy Gateway then
performs the task of connecting the battery storage system to PowerFlow Portal, a free online
monitoring website run by PowerFlow Energy.
PowerFlow Portal provides a number of features for the monitoring and control of the Sundial
battery storage system.
Monitoring includes a live energy flow reading of the building and the live battery status
updated every 15 seconds. In addition to the live display historical data is recorded and can be
displayed by selecting time periods for day, month and year.
Battery system control setup pages are also available to set pre defined charge periods for use
with night rate and multi-rate energy tariffs available from various supply companies.
The programming page enables adjustments for seasonal changes as well as differing energy
use profiles. Further information on PowerFlow Portal can be viewed online at
www.powerflowenergy.com
The diagram below illustrates a typical system layout.

4. Mounting
4.1 Selecting a Suitable Mounting Location
The Energy Gateway is designed to be wall mounted using the two mounting holes on the back of the
device. Mounting recommendations are:
 Ensure the Energy Gateway is mounted onto a secure surface using the supplied fixings.
 Do not mount the Energy Gateway outside, observe the IP20 ingress protection rating.
 Do not expose the Energy Gateway to direct sun light, as this can cause excessive internal heating.
 It is recommended to mount the Energy Gateway close to the Sundial battery system for easy
installation and to ensure good connectivity of the RS485 data line using the supplied 2M CAT5e data
cable. If it is not possible to mount the Energy Gateway next to the Sundial System, a longer CAT5E
cable may be used up to a maximum of 30 meters.
 The Energy Gateway will require mains power and therefore should be installed next to a 230V mains
socket outlet.
 The Energy Gateway will require an internet connection. Ensure that if using the hard wired LAN con-
nection it is possible to run the CAT5e cable back to the internet router. It is possible to use a longer
CAT5e than the 2M one supplied. It is also possible to use an additional powerline adaptor if it is not
possible to run the CAT5e cable back to the internet router. If a WiFi connection is required, please
ensure the mounting position of the Energy Gateway is within range of the WiFi singnal within the
building’s WiFi router.

6. Connecting to the Internet
The Energy Gateway must be connected to the internet in order to connect the Sundial battery storage
system to PowerFlow Portal. The Energy Gateway can be connected in two ways, either by hard wired LAN
connection using the RJ45 LAN connection or by using the internal WiFi capability to connect to the
buildings WiFi service.
6.1 Setting up the WiFi connection
The Energy Gateway has an internal WiFi capability which can be setup to connect to the building’s WiFi
router. In order to connect to the Energy Gateway and setup the internal WiFi connection a second WiFi
connection is provided in the form of the included USB WiFi dongle. By plugging this into one of the USB
connections on the Energy Gateway, it is then possible to connect to the Energy Gateway via the WiFi
dongle using the WiFi connection from a laptop, PC or tablet.
1. Ensure the installation of the Energy Gateway has been completed, the WiFi dongle is plugged
into one of the USB sockets and the mains power adaptor has been switched on. The green pow-
er LED will indicate correct connection, Wait 2 minutes for the Energy Gateway to boot up.
2. Ensure that the PC being used is within WiFi range of the both the Energy Gateway and buildings
WiFi router.
3. Open the Wireless network connection window on your PC and look for new WiFi networks. The
serial number of the gateway (this can be found on the front label of the gateway) will be dis-
played in the Wireless networks connection list. Click on the serial number to connect to the Ener-
gy Gateway, the password is 0000000000 (ten zero’s) and required for connection.
4. Once connected to the Energy Gateways WiFi network, open a new internet page and in the ad-
dress bar type the following IP address: 10.10.0.1 (all other browsers are possible), press ‘Enter’

5. The following page will open: Enter the buildings wireless router name (SSID) and the password
for the buildings wireless network. Click ‘Configure Wireless’ to save the settings, a setting page
will display the connection information.
6. Exit the configuration page and switch off the Energy Gateway at the mains plug to allow the
Energy Gateway to shut down. Wait until the power status light is flashing red.
7. Turn the Energy Gateway back on at the mains plug and wait 2 minutes, allowing time for the
Energy Gateway to boot up.
8. The Energy Gateway should now be connected to the buildings router via WiFi.
9. It is possible to check the connection status by logging back into the configuration page.
10. To do this, repeat steps 2 —4 and click on the check configuration button. The checking wireless
configuration page will be displayed and the following information can be viewed:
Gateway Serial Number
Gateway MAC address
SSID of connected WiFi Network
Password of connected WiFi Network
Connection Status
11. Click the back button to exit the page, The Energy Gateway is connected to the internet.
12. Go to Section 7, Registering a new PowerFlow Portal account for next steps.

6.2: Setting up the Hard wired LAN connection
The Energy Gateway has an RJ45 LAN connection which can be used to connect to the building’s internet
router.
TIP: If it is not possible to connect the LAN cable from the Energy Gateway to the internet router because
of its location, and the Energy Gateway is out of range of the WiFi signal, it is possible to use the LAN
connection together with a Powerline Line adaptor device (sold separately) to achieve connection.
1. Ensure the installation of the Energy Gateway has been completed, the LAN cable has been con-
nected to the internet router and the mains power adaptor has been switched on. The green
power LED will indicate correct connection, Wait 2 minutes for the Energy Gateway to boot up.
2. The Energy Gateway will automatically connect to the internet.
3. The network connection status can be checked by following steps in section 6.1. Once the config-
uration page is available click on the connection status button to review the connection details.
4. Should it be required to disable the WiFi connection when using the hard wired LAN connection
follow the steps in section 6.1 to create a new WiFi connection. Once the configuration page is
available, input XXXXXX into both the SSID and password fields, this will disable the WiFi. It can
always be changed in the future by inputting the correct wireless network SSID and password.
5. Once the Energy Gateway is successfully connected to the internet Go to Section 7, registering a
new PowerFlow Portal account for next steps.

Once the Energy Gateway has been connected to the internet it will automatically connect to PowerFlow
Portal. The Energy Gateway’s serial number has been pre registered during manufacture but must be
linked to a new PowerFlow Portal account.
1. Please go to http://powerflowenergy.co.uk/portal/login.html and click on
‘Register an Account’.
2. In the registration page an email address and password must be entered. In addition enter the
Gateway serial number into the system ID number box. The location of the system ID number
(serial number) can be found on page 9. Once the account has been activated it is then possible to
login and view the system.
Register a new account
7. Registering a new PowerFlow Portal Account

Gateway serial number
into the system ID box
