Important Safety Notice:
The Sunny Island inverter may only be opened, installed and ser-
viced by qualified personnel. The device can still be charged with
very high hazardous voltages even when disconnected. Please
closely follow all steps as described in this document when working
on the inverter.

Sunny Island Installation & Operating Instructions

1 Introduction
By purchasing a Sunny Island you have decided to use one of the most advanced
modular battery inverters. The Sunny Island complies with the according European
harmonized standards on electromagnetic compatibility as certified in the CE decla-
ration (see appendix).
In the following you will find the installation and operating instructions of the Sunny
Island battery inverter. Don’t worry about the size of the document, it is not neces-
sary to read everything at once. This is both installer’s guide and user manual, so it
is used as reference for the commissioning and as guideline on how to use all func-
tions of the inverter optimally and how to extend your existing PV-plant. For detailed
information on system realization, functions and the integrated battery and load
management please refer to the Product Description.

1.1 About these instructions
This document contains important information for the installation and commissioning of
the Sunny Island as well as its safe operation. Please read these instructions carefully
before starting the inverter. The inverter must be installed and commissioned by quali-
fied personnel. Work must be carried out according to the local installation and safety
regulations. Please also refer to our warranty and liability terms at the end of this docu-
ment.
This version of Installation and Operating Instructions considers the new features of
Firmware BFR 1.50 / DSP 1.50 and higher. Basically, these Instructions continue to
refer to inverters with firmware BFR 1.10, however discrepancies concerning the pa-
rameters/data available can arise. Please note that changes have been made com-
pared to earlier versions (before Firmware BFR 1.10) as regards generator control
(allocation of relays), (see chapter 3.4.6).
1.2 What to do in case of transport damages?
Our products are thoroughly checked before they are shipped. Even though they are
delivered in sturdy packaging (which can be recycled) the inverters can be damaged
in transit which is usually the forwarder’s fault.
Please inspect your inverter thoroughly after it has been delivered. If any damages
can be detected on the packaging that could make you conclude the contents is
damaged or if you detect any damage please immediately notify the forwarding com-
pany.
SMA or your local supplier can help you in this matter. In any case a declaration of
transport damage must be made within six days upon receipt of the product and
must be stated in writing directly to the forwarding agent.
