SMA Solar Technology AG
Any use of the product other than that described in the Intended Use section does not qualify as appropriate.
The enclosed documentation is an integral part of this product. Keep the documentation in a convenient, dry place for
future reference and observe all instructions contained therein.
This document does not replace any regional, state, provincial, federal or national laws, regulations or standards that
apply to the installation, electrical safety and use of the product. SMA Solar Technology AG assumes no responsibility
for the compliance or non-compliance with such laws or codes in connection with the installation of the product.
The type label must remain permanently attached to the product.
Additional requirements for an off-grid system
Off-grid systems with Sunny Island are used to set up self-sufficient utility grids. The Sunny Island forms the stand-alone
grid as a voltage source. The Sunny Island regulates the balance between the energy fed in and energy used and
features a management system that manages the battery, generators and loads. AC sources (e.g. PV inverters) supply
loads and are used by the Sunny Island to recharge the battery. In order to be able to increase the availability of the
off-grid system and reduce the battery capacity, the Sunny Island can use and control a generator as an energy
source.
The locally applicable standards and directives must also be observed for off-grid systems. Loads in off-grid systems
are not protected against power failure.
Off-grid systems with Sunny Island form single-phase or three-phase AC distribution grids.
In off-grid systems, the maximum output power of the non-adjustable AC current sources (e.g. wind turbine system or
CHP plant) must not exceed the total power of all Sunny Island devices (for technical data, see the Sunny Island
operating manual).
The connected PV inverters must be suitable for use in off-grid systems. The power of the PV system must be
appropriate for the system (see planning guidelines "Design of Off-Grid Systems with Sunny Island Devices" at
www.SMA-Solar.com).
Device type SI4.4M-13 must not be used for single-phase single-cluster systems and not for three-phase multicluster
systems (see planning guidelines "Design of Off-Grid Systems with Sunny Island Devices").
Several clusters may only be interconnected if the Multicluster-Box 6 / 12 (MC-BOX-12.3-20) / 36 is used.
Additional requirements for an SMA Energy System Home
The SMA Energy System Home is a storage system and optimizes self-consumption of PV energy by the following
measures:
• Intermediate storage of excess PV energy with the Sunny Island
• Visualization of PV system data in Sunny Portal
The SMA Energy System Home does not form a battery-backup grid in the event of utility grid failure (for installation of
a battery-backup system, see the system description "SMA Energy System Home with Battery-Backup Function" at
www.SMA-Solar.com).
The SMA Energy System Home must only be used in those countries for which it is licensed or in those countries for
which it is approved by SMA Solar Technology AG and the grid operator. The grid configuration of the utility grid
must be a TN or TT system.
Grid feed-in and purchased electricity are recorded with an SMA Energy Meter only. An SMA Energy Meter does not
replace the energy meter of the electric utility company.
Single-phase clusters are not permitted. In a three-phase cluster, only device types with the same output power may be
installed. This means that the device types, such as SI6.0H-12 and SI6.0H-13, may be combined within a cluster. In
contrast, device types with different outputs (e.g. SI6.0H-13 and SI8.0H-13) may not be combined. The cluster master
must always be an SI4.4M-13 / SI6.0H-13 / SI8.0H-13. It must be equipped with the latest firmware version.
