Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Only open the product if the humidity is within the thresholds and the environment is free of sand and dust.
• Do not open the product during a dust storm or precipitation.
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.
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). Observe the applicable safety regulations.
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 inverters 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.
2.3 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.
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.
