PRODUCTS | SERVICES The Resol FlowSol E for converting excess current into thermal energy The Resol FlowSol E has been especially designed for using excess current produced by a photovoltaic system. The station contains all thevital hydraulic components, is particularly easy to install and can be retrofi tted into all heating and DHW systems. “The measuring device reliably detects excess current and the integrated controller redirects it to a steplessly variable electric heater for heating a water store,” explains Gerald Neuse, Resol Head of Sales, and adds: “Thus, excess power can be stored as regenerative heat, internal consumption can be increased while decreasing conventional heating costs”. All the while, of course, household power has absolute priority and grid compliance is maintained. “The intelligent control ensures an optimum store stratifi - cation so that even small amounts of excess power can be reliably converted into heat and power fl uctuations can be balanced out,” relates Gerald Neuse and concludes: “The Resol FlowSol E becomes the missing link between the photovoltaic system and the heat generator – for more independence, decreased heating costs and less CO2 emissions”. New rotary encoder technology highlight Pepperl+Fuchs has created a new breakthrough in rotary encoder technology with the new magnetic absolute rotary encoders in the 0.1° accuracy class. Their outstanding performance in terms of precision and dynamics, combined with extreme robustness in compact designs, offers signifi cant advantages in virtually all areas of machinery and plant engineering to offshore equipment and mobile equipment applications. Rotary encoders that use the magnetic detection principle are particularly robust and compact based on the technology they use. In heavy-duty applications and environmental conditions, the encoders are unaffected by contamination by dust, oils, aggressive emulsions, or infl uences such as extreme temperatures, vibration, impact, shock etc. In the new 0.1° accuracy class magnetic absolute rotary encoders, Pepperl+Fuchs combines these properties with a high level of precision and dynamics. The encoders exhibit measurement accuracies of up to 0.08° at a singleturn resolution of up to 16 Bit, a multiturn resolution of up to 39 Bit, and dynamics that, in relation to the sampling time of <80 μs, push the boundaries of what has previously been possible. “This outstanding performance meets market requirements arising from more challenging environmental conditions with ever faster processes and growing demands on process reliability” explains Stefan Horvatic, the responsible product manager at Pepperl+Fuchs Drehgeber GmbH. As typical examples, he mentions the existing traditional application fi elds for magnetic rotary encoders: mobile equipment, commercial vehicles, and wind turbines: “On the one hand, magnetic rotary encoders are perfect for increasingly challenging locations. On the other hand, ever larger plants with longer axes and traverse distances make increased demands on accuracy” says Horvatic. SolarMax Group presents its system solution MaxStorage TP-S for storing solar energy The SolarMax Group is presenting its new storage solution MaxStorage TP-S for the very fi rst time at the Intersolar Europe in Munich. The new system solution has a modular construction, uniting lithiumion battery storage, a battery management system, a tried and tested SolarMax TP-Series inverter and the new MaxWeb XPN energy manager, all in one casing. For the inverters, customers can choose between three TPSeries devices with rated outputs of fi ve to seven kilowatts. Thanks to their dynamic 70% power reduction they can control consumers to increase self-consumption. The basic storage module has a capacity of 3.6 kilowatt-hours and can be extended in stages of 1.2 kilowatt-hours up to 12 kilowatt-hours. The DC-coupled system achieves a charging effi ciency factor of 97 per cent, and it can be discharged in wide operating range of -20 to + 60 (only valid for the inverter) degrees Celsius. For managing energy, the SolarMax Group has developed the new MaxWeb XPN data logger. As nodal point for remote monitoring it records current readings, yield data and events. As an energy management centre it regulates the energy fl ow and adjusts it to suit energy need and availability. 76 energética INTERNATIONAL · Nº 158 · JUN/JUL16
