SMA Sunny Island battery/grid inverters
SUNNY ISLAND – The flexible System manager
The Sunny Islands offer you first class possibilities in the installation of self-sufficient energy systems. In conjunction with a battery pack the devices form a self-sufficient AC voltage grid, which meets with the highest of quality standards.
In the Sunny Island System, electricity generators and consumers are integrated in equal measure. PV and wind energy systems, diesel devices, water or CHP (Combined Heat and Power) can be coupled on the AC side just as conventional 230 Volt consumers. Thus the Sunny Islands offer you two decisive advantages: at system planning and layout you can enjoy the highest degree of flexibility, during installation the complex DC cabling is not required.
Sunny Island 6.0 / 8.0
Simple. Robust. Flexible.
More robust than its predecessors: The new Sunny Island impresses with its high protection class and wide temperature range. Moisture, dust and temperature fluctuations won’t impair its operation, even after 20 years. Thanks to OptiCool, there’s no need to compromise when it comes to overload capacity and profitability. And there’s more: OptiPower, the intelligent load and energy management system, ensures operation even in critical situations. OptiUse makes installation, commissioning and daily use easier than ever with automatic rotary field detection, an optimized quick configuration guide and intuitive operation. And the OptiBat battery management system automatically controls the most important charging and discharging procedures, which extends the service life of sensitive energy storage. Sunny Island is a truly comprehensive package for a worry-free, reliable and self-sufficient electricity supply.

Sunny Remote Control
The SMA Sunny Remote Control makes SMA off grid solar photovoltaic systems using SMA Sunny Island and SMA Sunny Backup even more flexible. The SMA Sunny Remote Control maximizes the ease of installation by moving the control unit to the outside of the inverter. With the SMA Sunny Remote Control, you can commission and monitor the SMA Sunny Island and SMA Sunny Backup conveniently without standing right in front of the inverter. The SMA Sunny Remote Control SRC-20 can be used at a distance of up to 20 meters and processes information from up to three inverters. The rotary switch allows intuitive operation. The four-line display gives you clearly arranged information on the current plant status at one glance. An SD card serves as the service interface for the inverter which adds to the simplicity of installing the SMA Sunny Remote Control SRC-20. Just one cable is needed for the electrical connection and communication. Plug it in at both ends – and there you are.

Smart Load for Sunny Island
Intelligent Dump Load for Stand-Alone Grids
Smart Load for Sunny Island
The Smart Load is an electronic control for load resistors up to 6 kW from Critical Power Supplies optimized for the operation in Island grid systems with energy sources that only have a slow control or none at all Single phase or 3 phase input IP65
Intelligent dumpload for stand-alone grids
The Smart Load forms the perfect complement to unregulated energy generators in stand-alone grids, e.g., small, directly-connected wind generators with passive stall power control. If there is an electricity surplus, the Smart Load feeds it into special loads, for example, heating cartridges in a hot water tank. The necessary arrangement is completely automatic, fast and free of retroactive effects for other loads. This continuous and quick energy consumption allows for ideal protection of system components and guarantees increased reliability.
