Inverters are transformerless three-phase inverters that, with their output voltage of 480V, are particularly suitable for connection to external transformers of large decentralised systems. These units give you fl exibility in designing your PV system. They operate using three separate MPP trackers that can handle both symmetrical and asymmetrical loads to allow for optimum adjustment.

The input voltage range is particularly broad: the inverters switch to the grid from 250V, and, when in operation, they still feed in at 200 V. The peak effi ciency is 98.3 %. The European effi ciency is also worth noting and is due to the fact that the unit has a very high partial load effi ciency in the lower power ranges. Even at just 5 % rated power they operate at 95 % effi ciency. It is easy to achieve perfect communication with these units. They are fi tted with an integrated data logger with web server, a graphical display for showing operating data and a USB port for installing fi rmware updates. The current software can be downloaded from the download area of www.kaco-newenergy.com. The yield data can be called up via USB or the web server. The integrated data logger can also be connected directly to an internet portal for professional evaluation and visualisation of the operating data.
