Telit Wireless Solutions has won IPM System International as a new client. The Germany-based company specializes in the area of renewable energy, developing innovative regulation and control technology for the optimization of solar photovoltaic panels. The photovoltaic specialists’ solution portfolio is centered around the Intelligent Power Management System (IPM System). This is a Smart Grid-compatible system that can be regulated and controlled to boost the efficiency, transparency, flexibility and safety of photovoltaic systems. The solution can be used with both new and existing systems, and can therefore also be integrated retroactively and cost-effectively into solar power systems. The central solution approach is an intelligent variable switching arrangement of the individual solar modules, which differs from the series switching arrangement that is most commonly used, allowing the efficiency to be boosted by up to 21 per cent.
Photovoltaic systems are monitored and controlled via Machine-to-Machine communication. This means that the status of the PV systems can be verified at any time, or the anticipated energy yield determined. Faults or efficiency losses can also be rapidly detected through M2M communication. It also forms the basis for the setup of the smart grids of tomorrow, intelligent power networks that require the complete communications-based networking and management of equipment for generating, transferring and distributing energy. SIM cards from Telekom Deutschland and radio modules from Telit are being used for the M2M data transfers in the IPM System. The IPM System uses the GSM/GPRS module GE865 from Telit. Measuring just 22 x 22 x 3 mm, it is the ideal solution for M2M applications in areas where size and installation height are critical factors such as PDAs or telematics terminals, for example. The modules are manufactured using BGA technology and are therefore produced on a cost-optimizing basis since no other system connectors are needed.
