The AC sources must be suitable for stand-alone mode with Sunny Island (see Technical Information "PV Inverters in Off-Grid Systems" at www.SMA-Solar.com). The maximum output power of the AC sources in a stand-alone grid must be observed (see the Sunny Island inverter installation manual). -
Page 8: Safety Precautions
The list of lithium-ion batteries approved for the Sunny Island is updated constantly (see Technical Information "List of approved lithium-ion batteries" at www.SMA-Solar.com). • If no lithium-ion batteries approved for Sunny Island can be used, you should use lead-acid batteries. - Page 9 SMA Solar Technology AG 2 Safety Danger to life from electric shock due to live voltage High voltages are present in the off-grid system. When covers (e.g., an enclosure lid) are removed, live components can be touched, which can result in death or serious injury due to electric shock.
- Page 10 2 Safety SMA Solar Technology AG 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 at the DC terminal can lead to burns and may damage the Sunny Island.

A generator current control ensures that the generator always remains at the optimum operating point. The generator management allows the use of generators that have a low output power in proportion to the nominal load (see Technical Document "Sunny Island - Generator Whitepaper" at www.SMA-Solar.com) Load Control The load control enables control of the AC sources in stand-alone grids, control of a generator, and the specific disconnection of loads. -
