2.1 Intended Use
Sunny Island
The Sunny Island is a bidirectional off-grid inverter and forms a stand-alone grid.
Figure1: Principle of an off-grid system with a Sunny Island and a Sunny Remote Control
Only use the Sunny Island in accordance with the information provided in the enclosed
documentation. Any other use may result in personal injury or property damage.
Life-threatening voltages occur in the Sunny Island.
• Never operate the Sunny Island without the enclosure lid in place.
• Only skilled persons may open the Sunny Island.
The Sunny Island uses batteries for energy storage. The rated voltage of the battery must correspond
to the DC input voltage. A fuse-switch-disconnector, e.g. a BatFuse must be installed between the
battery and the Sunny Island.

2 Safety SMA Solar Technology AG
10 SI80H-BE-BEN120810 Operating Manual
DC loads and DC sources can be integrated in the off-grid system. The Sunny Island is not suitable
for establishing a DC distribution network.
The Sunny Island is not suitable for supplying life-sustaining medical devices.
• Never use the Sunny Island in systems in which a power outage might result in personal injury.
The Sunny Island can control various components in an off-grid system via two multi-function relays,
e.g. a load-shedding contactor. The multi-function relays are not suitable for controlling components
which may place people at risk if the multi-function relays malfunction, e.g. if the battery chamber
ventilation is not sufficiently redundant.
The enclosed documentation is an integral part of this product.
• Read and adhere to the documentation.
• Keep the documentation in a convenient place at all times for future reference.
Sunny Remote Control
You can configure and control the off-grid system centrally with the Sunny Remote Control display.
The Sunny Remote Control is only suitable for indoor use.

2.3 Safety Precautions
Electric Shock
High voltages are present in the off-grid system and in the off-grid inverter. The off-grid inverter can
start automatically from standby mode. Work on electrical connections of the off-grid inverter must be
performed by a skilled person. Observe the following safety instructions before working on the
electrical connections:
• Turn off or disconnect the following components in the specified order:
– Off-grid inverter
– All loads, AC sources, external energy sources and DC sources
– Miniature circuit-breakers and switch-disconnectors for AC sources and the external energy
source in the sub-distributions
– BatFuse switch-disconnector
• Ensure that the device cannot be reconnected.
• Open the enclosure lid and ensure that no voltage is present.
• Earth and short-circuit the AC conductors.
• Cover or safeguard any adjacent live components.
Explosion
Explosive gases may escape from the battery.
• Do not allow open flames, embers, or sparks near the battery.
• Maintain and operate the battery according to the manufacturer's specifications.
• Do not throw batteries into fire.
Acid Burns and Poisoning
If handled inappropriately, electrolyte from the battery can burn the skin or eyes and/or be toxic.
• Protect the battery enclosure against destruction.
• Do not open or deform the battery.
• Whenever working on the battery, wear rubber gloves, rubber boots and goggles.
• Rinse acid splashes with clear water and consult a doctor.
• Maintain and operate the battery according to the manufacturer's specifications.
Crushing
Moving parts in the generator can crush or sever body parts. The generator can be started
automatically by the off-grid inverter.
• Only operate the generator with the safety equipment.
• Maintain and operate the generator according to the manufacturer's specifications.

Burn Hazards
Some parts of the off-grid inverter enclosure can become hot during operation.
• During operation, touch the off-grid inverter on the enclosure lid only.
Short-circuit currents in the battery can cause heat build-up and electric arcs. Observe the following
safety instructions before working on the battery.
• Remove watches, rings and other metal objects.
•Use insulated tools.
• Do not place tools or metal parts on the battery.

3 Product Description
3.1 Sunny Island 8.0H / 6.0H
The Sunny Island is a bidirectional off-grid inverter and forms a stand-alone grid.
Figure2: Design of the Sunny Island 8.0H / 6.0H
The Sunny Island supplies AC loads in the stand-alone grid from a battery or charges the battery with
the energy provided by sources on the AC side. AC sources in the stand-alone grid (e.g. PV inverters)
supply loads and are used by the off-grid inverter to recharge the battery. In order to increase the
availability of the stand-alone grid and reduce the battery capacity, the Sunny Island can use and
control external energy sources (e.g. a generator) as an energy reserve.
The Sunny Island supplies the loads with active power and reactive power. The loads may temporarily
overload the Sunny Island. If there is a short circuit in the the stand-alone grid, the Sunny Island also
briefly feeds in short-circuit currents to the stand-alone grid. As a result, the Sunny Island may trip
miniature circuit-breakers. Miniature circuit-breakers only disconnect electric circuits that are affected
by the fault.
The off-grid system must be a TN or TT system. The Sunny Island does not support IT systems.
