System ManualSBSUL9540-SH-en-108
2 Safety
2.1 Intended Use
The SMAEnergySystem is a storage system and optimizes self-consumption of PV energy and
lowers the energy obtained from the utility grid by the following measures:
• Intermediate storage of PV energy in the battery
• Data logging at the grid-connection point with the energy meter (Modbus RTU)
• Visualization of the consumption and generation data from your system in SunnyPortal
Impairment of system communication
The use of external, unapproved components can affect the system communication.
• Only use approved components in the system.
Grid feed-in and purchased energy (from the utility grid) are only recorded with the energy meter
(Modbus RTU). The energy meter (Modbus RTU) does not replace the energy meter of the electric
utility company.
Use SMA products only in accordance with the information provided in the enclosed
documentation and with the locally applicable laws, regulations, standards and directives. Any
other application may cause personal injury or property damage.
2.2 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working.
DANGER
Danger of fatal electric shock due to non-compliance with the safety
instructions in the documents that are enclosed with each product.
This document supplements the documents that are enclosed with each product and does not
replace any locally applicable codes or standards.
• Read and observe all documents enclosed with the products.
If the AC connection of the inverter is disconnected and the battery is
switched off, there is no risk of electric arcs during installation or servicing.
If the AC circuit breakers of the inverters are switched off and secured against reconnection
and the battery or the load-break switch of the battery is turned off and secured against
reconnection, there is no danger of an electric arc during installation or servicing. Be aware
that, when using batteries from BYD, the individual battery modules do not have their own
disconnects. With BYD batteries, all modules are disconnected by means of the BCU's main
switch. The AC circuit breaker of the inverter must be installed in the distribution board.

observed.
This document supplements the documents that are enclosed with each product and does not
replace any locally applicable codes or standards.
• Read and observe the requirements in the documents enclosed with the products in
addition to the requirements stated below.
☐ The system may be installed outdoors. The system components must not be exposed to direct
solar irradiation and must be protected from rain water. When becoming too hot, the system
reduces its power output to avoid overheating.
☐ The system must not be installed in earthquake-prone areas.
☐ The system must not be installed in coastal areas where salt spray is possible.

• Switch on the AC circuit breaker.
☑ All three LEDs light up. The start-up phase begins. All three LEDs go out again after
approximately 90seconds.
☑ Depending on the available power, the green LED pulses or is continuously illuminated. The
inverter is feeding in.
6.3.2 Establishing a Connection to the User Interface of the
Battery Inverter
SSID, IP address and necessary passwords
• SSID in WLAN: SMA[serial number] (e.g. SMA0123456789)
• Standard WLAN password (usable until completion of the configuration by means of the
installation assistant or prior to the end of the first tenfeed-in hours): SMA12345
• Device-specific WLAN password (usable after initial configuration and completion of the
first tenfeed-in hours): see WPA2-PSK on the type label of the inverter or on the back of
the manual included in the delivery
• Standard IP address for a direct connection via WLAN outside of a local network:
192.168.12.3

6 Commissioning SMA Solar Technology AG
System ManualSBSUL9540-SH-en-1020
Requirements:
☐ An end device (e.g. computer, tablet PC or smartphone) must be available.
☐ The respective latest version of one of the following web browsers must be installed: Chrome,
Edge, Firefox, Internet Explorer or Safari.
☐ JavaScript must be enabled in the web browser of the end device.
☐ The SMA Grid Guard code of the Installer must be available for the changing of grid-relevant
settings after completion of the first ten feed-in hours or installation assistant (see "Application
for SMAGridGuard Code" at www.SMA-Solar.com).
Procedure:
1. If your end device has a WPS function:
• Activate the WPS function on the inverter. To do this, tap twice on the enclosure lid of the
Connection Unit.
☑ The blue LED flashes quickly for two minutes.
• Activate the WPS on your end device.
☑ The connection with your end device will be established automatically. It can take
up to 20seconds for this connection to be established.
2. If your end device does not have a WPS function:
• Search for WLAN networks with your end device.
• Select the SSID of the inverter SMA[serial number] in the list with the found WLAN
networks.
• Enter the inverter WLAN password. Within the first tenfeed-in hours and prior to
completing the configuration by means of the installation assistant, you must use the
standard WLAN password SMA12345. After the first tenfeed-in hours or after
completing the configuration by means of the installation assistant, you must use the
device-specific WLAN password (WPA2-PSK) of the inverter. You find the WLAN
password (WPA2-PSK) on the type label.
