NOTICE
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic discharge.
• Ground yourself before touching any component.
NOTICE
Damage to the enclosure seal in subfreezing conditions
If you open the product when temperatures are below freezing, the enclosure seals can be damaged. Moisture can
penetrate the product and damage it.
• Only open the product if the ambient temperature is not below -5°C.
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing, remove it prior to
opening the product (e.g. by melting the ice with warm air).
NOTICE
High costs due to inappropriate Internet tariff
Depending on use, the data volume of the product transferred via the Internet may vary in size. The data volume
depends, for example, on the number of devices in the system, the frequency of device updates, the frequency of
data transfer to Sunny Portal or the use of FTP push. High costs for the Internet connection can be the result.
• SMA Solar Technology AG recommends using an Internet flat rate.
A country data set must be set for feed-in operation
To ensure the inverter begins feed-in operation during initial commissioning, a country data set must be set (for
instance via the installation assistant on the user interface of the product, or via a communication product).
If no country data set is set, then feed-in operation will be stopped. This state is signaled by orange glow of the
inverter LED. The power LED and the battery LED are off.
The inverter will automatically start feed-in operation only after the inverter configuration is completed.

Battery Safety Information
This section contains safety information that must be observed at all times when working on or with batteries.
To prevent personal injury or property damage and to ensure long-term operation of the batteries, read this section
carefully and observe all safety information at all times.
WARNING
Danger to life due to incompatible lithium-ion battery
An incompatible lithium-ion battery can lead to a fire or an explosion. With incompatible lithium-ion batteries, it is
not ensured that battery management is intrinsically safe and will protect the battery.
• Ensure that the lithium-ion batteries are approved for use with the Sunny Island (see technical information “List
of Approved Batteries” at www.SMA-Solar.com).
• If no lithium-ion batteries approved for the inverter can be used, lead-acid batteries can be used.
• Verify that the battery complies with locally applicable standards and directives and is intrinsically safe.
