Battery Safety Information - SMA SUNNY ISLAND 4.4M Notice Résumée

SMA Solar Technology AG
Risk of burns due to short-circuit currents on the disconnected inverter
The capacitors in the DC input area of the inverter store energy. After the battery is isolated from the inverter,
battery voltage is still temporarily present at the DC terminal. A short circuit at the DC terminal of the inverter can
lead to burns and may damage the inverter.
• Wait 15 minutes before performing any work at the DC terminal or on the DC cables. This allows the
capacitors to discharge.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Mount the inverter in such a way that it cannot be touched inadvertently during operation.
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).
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.
