Risk of burns due to short-circuit currents on the disconnected Sunny Island
The capacitors at the DC connection input area store energy. After the battery is isolated from the Sunny Island, battery
voltage is still temporarily present at the DC terminal. A short circuit on the DC connection can lead to burns and may
damage the Sunny Island.
• Wait 15 minutes before performing any work at the DC connection or on the DC cables. This allows the capacitors
to discharge.
Risk of burns due to hot components
Some components of the Sunny Island can get very hot during operation. Touching these components can cause burns.
Heat build-up can cause burns.
• During operation, do not touch any parts other than the enclosure lid of the Sunny Island.
• When the Sunny Island is open, do not touch hot surfaces.

Destruction of the Sunny Island inverter due to electrostatic discharge (ESD)
By touching electronic components within the Sunny Island, you can damage or destroy the Sunny Island.
• Do not touch any electronic assemblies.
• Ground yourself before touching any connections.
