Risk of burns due to short-circuit currents on the disconnected Sunny Island
The capacitors at the DC terminal input area store energy. When isolating the battery from the Sunny Island, there is
still battery voltage present on the DC terminal temporarily. A short circuit on the DC terminal can lead to burns and
may damage the Sunny Island.
• Wait 15 minutes before performing any work at the terminal or on the DC cables. This allows the capacitors to
discharge.

Damage to the battery due to incorrect settings
Incorrect settings can lead to premature aging of the battery. Settings of the parameters in the menu 220# Battery
influence the charging behavior of the Sunny Island.
• Ensure that the values recommended by the battery manufacturer are set for the battery (for the battery technical
data, see the documentation of the battery manufacturer).
Destruction of devices due to electrostatic discharge (ESD)
If enclosure parts are removed, the devices (e.g., Sunny Island or PV inverter) can be damaged or destroyed if
electronic components or terminals are touched.
• Do not touch any electronic components in open devices.
• Ground yourself before touching any terminals.
