SMA Technologie AG was founded as an independent company out of Kassel's University in 1981 with the vision to develop and produce intelligent computer-based control systems for decentralized energy supply. This vision resulted in sophisticated products that are fail-safe and extremely reliable especially since an energy supply system has to guarantee long-term trouble-free operation.
Due to their know-how from 20 years of experience in the development and fabrication of system technology for photovoltaic, wind energy and combined power generation plants, the continuous product improvements and the use of absolutely new technologies has made SMA a pioneer in the field of solar technology. The close cooperation with the ISET (Institut für Solare Energieversorgungstechnik) in the field of research resulted in innovations that have set standards specifically for decentralized power supply systems.
SMA is certified to DIN ISO 9001:2000. In addition to this, SMA also has numerous product-specific certificates. Copy of this certificate can be found on the attached CD in the folder named Certifications.
The SMA Sunny Boy inverter is a worldwide market leader in the field of innovative device technology for the use of renewable energy sources. Private, commercial and institutional owners of solar power plants rely on SMA’s Sunny Boy photovoltaic inverters and their numerous possibilities of a wide range of different communication and monitoring systems. Due to the ultramodern electronics manufacturing SMA ensures quality, reliability, and up-to-date technology of the components that are being developed. SMA’s long-standing experience in the field of power electronic components and computer-based systems guarantees top quality and highly efficient inverters.
The Sunny Boy family of inverters is a technically mature device, which is currently the most advanced modular PV system technology available for connecting PV systems to the grid. SMA inverters distinguish themselves particularly by their high levels of efficiency, reliability and the ease with which they can be operated in parallel with other inverters. In addition the inverters conform to the electromagnetic tolerance regulations and the low voltage regulations of the relevant combined European norms, as confirmed in the CE conformity declaration available on the attached CD in the folder named Certifications.
All SMA inverters are all equipped with a grid guard. This is a type of disconnection device that will disconnect the inverter from the grid if there is a power failure. It ensures that all inverters comply with the German Electricity Industry Association -VDEW – regulations for the connection and parallel operation of electrical power units to the low voltage grid of the electricity supply company and with DIN VDE 0126-1-1, which forms part of these regulations.
In addition to this, the inverters are installed with ground fault monitoring and overvoltage protection devices. Also all transformer less inverters are equipped with a leakage current measuring device. All these devices will safe guard both the equipment and user from potential damages and harm respectively.
The inverter is also supplied with a specifically designed Electronic Solar Switch (ESS). This dc circuit breaker for solar inverters allows the inverter to be safely disconnected from the PV array, even in a faulty system. Without this electronic solar switch the removal of the dc plug can cause arcing, which may cause personal injury and damage to the inverter. This ingenious device is in the shape of a handle and is assembled on the underside of the inverter. After switching off the ac side, this handle is pulled out to switch off the PV array input to the inverter. Once pulled out the dc plug can be safely removed. The handle is small and can be easily carried anywhere thereby minimizing the risk that someone else will switch it on again. The user manual of this device can be found in the CD in the folder named Manuals.
Each SMA inverter has an illuminated display installed on its front cover. The display shows the most important operational information such as energy generated, performance etc and fault codes of the inverter.
SMA stress that their inverters and other products may only be installed by trained specialists. We have been trained by SMA themselves in the design and installation of PV systems. The training for RECOWATT personnel was conducted at SMA plant in Germany.
