SMA Power SetsSolar-Set SMA Power M
The intelligent power management optimally uses the existing energy resources and ensures a maximum life time of the battery. Due to the robust design of the components these systems may also be operated even under extreme climates. Thus, a reliable power supply is guaranteed at all times and wherever it is needed. The coupling of both, the power sources and consumers on the AC side allows for the utilisation of an already existing infrastructure and simplifies an on-site installation. Furthermore, additional energy sources, such as PV, wind and hydro power, fuel cells or chp plants may be easily integrated. Since - depending on weather conditions and the season - the full potential of the renewables will not be available all the time, fuel generators or any other AC source may be connected for backup power supply. The various components at a glance!
Functional principleThe main component of the SMA Power Sets is the bi-directional stand-alone battery inverter Sunny Island. Together wit the battery bank, the Sunny Island creates an AC voltage grid into which all components - from electrical appliances to power generators - can be integrated. In order to increase the output of the AC grid, the entire system may be upgraded up to 20kW 1-phase and up to 60kW 3-phase by parallelling several Sunny Island inverters. The SMA Power Sets M includes two Sunny Island off-grid inverter connected in parallel. Thus, the total power output of the system amounts to 10kW 1-phase with a short-term peak power of max. 17kW (<1 min.). 
The Sunny Island can be easily combined with renewable energy sources like solar or wind power by means of the Sunny Boy and Windy Boy inverters via the AC grid. Their easy installation, high level of efficiency and reliability are more than convincing. Furthermore fuel generators can be connected to the system and controled by the Sunny Island in a particulary fuel-saving manner. The battery connection box with integrated DC fuse disconnector provides additional safety during installation as well as when operating the system. The performance data and the functional status of the various components may be recorded centrally by using the Sunny Webbox. Connected to the Internet, the Sunny Webbox can be accessed from all over the world. System performanceThe actual energy made available by the SMA Power Set depends on the geographic location of the installation site. In Central Europe, a constant solar power supply throughout the year is not possible, because of the poor insolation during winter months. According to the application it is recommended to reduce the consumption during these months or to use a conventional power generator to fill the gap. In Southern Europe, the seasonal variations are less distinct and, depending on the site of installation, the energy requirement may be covered entirely by solar power. For example, the SMA Power Set M is ideal for providing energy to larger remote homes in Southern Europe. With a power output of 10kW the system ensures even the operation of heavy AC consumers. The volume of usable energy that is made available by the 5.78 kWp solar generator, amounts to 6.8500 kWh a year, at an average global irradiation of 5kWh/m² per day. The battery capacity of 38.4 kWh assures a system autonomy of 2 days. We recommend the use of a diesel generator of min. 6kW in order to make up for seasonal variations and to serve as a backup power supply.

In any case, before buying this system, check carefully if your requirements are met, in particular if the power set matches the projected consumer profile. Please, also refer to our system check for further information or contact us directly. Solar Generator Mounting OptionsThere are 3 mounting options available for the solar generator included in this power set. Please do not forget to specify the desired mounting option and the type of your roofing when ordering!
