The AC sources in the multicluster system must be suitable for stand-alone mode with Sunny Island (for PV inverters see planning guidelines "Design of Off-Grid Systems with Sunny Island Devices" at www.SMA-Solar.com). The maximum output power of the AC sources in a stand-alone grid must be observed (see the operating manual of the Sunny Island). -
Page 8: Important Safety Instructions
Alterations to the SMA products, e.g., changes or modifications, are only permitted with the express written permission of SMA Solar Technology AG. Unauthorized alterations will void guarantee and warranty claims and in most cases terminate the operating license. SMA Solar Technology AG shall not be held liable for any damage caused by such changes. - Page 9 SMA Solar Technology AG 2 Safety DANGER Danger to life due to electric shock in case of overvoltages and unsuitable loads Overvoltages of up to 1500 V can occur in the stand-alone grid and in the battery-backup grid. If the loads are not suitable for these overvoltages or are not safe to operate, a voltage that poses a danger to life may be present on accessible parts or cables.
- Page 10 2 Safety SMA Solar Technology AG WARNING Danger to life from electric shock due to circuit breakers that cannot be tripped In off-grid systems and battery-backup systems, the Sunny Island can only trip circuit breakers up to a certain tripping characteristic. Circuit breakers with a higher operating current cannot be tripped. Under fault conditions, a voltage that poses a danger to life may be present on accessible parts for several seconds.

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. The inverter supports different firmware versions that are suitable for different systems. - Page 12 • 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.
- Page 13 SMA Solar Technology AG 2 Safety CAUTION Risk of burns due to hot battery components Improper battery connection may result in excessively high transition resistances. Excessive transition resistances give rise to localized heat build-up. • Ensure that all pole connectors are connected with the connecting torque specified by the battery manufacturer.

This means that overcharging can be reliably prevented and that the battery can be fully charged regularly. The available charge energy is used optimally at all times (see technical information "Battery Management" at www.SMA-Solar.com). Generator Management The Sunny Island can synchronize with a generator and connect directly, if necessary. -

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. -

When using lead-acid batteries, the Sunny Island carries out full and equalization charges on a regular basis (see technical information "Battery Management" at www.SMA-Solar.com). As a result, the service life of the battery is increased. During full and equalization charges, the intermediate storage of PV energy is deactivated and electricity may have to be purchased to perform the full and equalization charges. -
