The power plants of the future. The transformerless three-phase inverters Powador 9.0 TL3 to 18.0 TL3. Photovoltaic systems of up to several hundred kilowatts can be designed extremely exibly in small, highly efcient units with the transformerless three-phase inverters Powador 9.0 TL3 to 18.0 TL3. They operate using two separate MPP trackers that can handle both symmetrical and asymmetrical loads to allow for optimum adjustment. Each tracker is able to process virtually all of the AC output. This allows for all typical requirements of complex designs to be fullled; on the one hand, for example, full conguration of an east/west-facing roof (symmetrical load) or, on the other hand, the regular conguration of a southfacing roof without having to dispense with the solar yield of a dormer (asymmetrical load). The MPP trackers can also be connected in parallel: installation costs less (you do not need an additional external disconnector) when strings need to be combined before the inverter. Two strings can be connected per MPP controller, i.e. 4 strings for each unit. The input voltage range is particularly broad: the inverters switch to the grid from 250 V, and, when in operation, they still feed in at 200 V. This means that solar yields are optimum for comparatively small areas such as dormers or carports but they also operate for more of the day. The peak efciency is 98 % and the European efciency is also above average. The compact design weighing only 40 kg combined with the DC connection via solar connectors makes installation very easy and economical. It is easy to achieve perfect communication with these units. They are tted with an integrated data logger with web server, a graphical display for showing operating data and a USB port for instal- ling rmware updates. The current software can be downloaded free of charge from the download area of www.kaconewenergy.de/service. The yield data can be called from the web server or via USB for evaluation. The integrated data logger can also be connected directly to the Powador web internet portal for professional evaluation and visualisation of the inverter data. A number of country-specic default settings are programmed into the inverters. These are easy to select during onsite installation. The interface language can be selected separately. The inverters conform to the German Medium and Low Voltage Directives and support the functions of the Powador-protect for grid and plant protection and also power management in accordance with the German EEG 2012.
