3.1 Description of the Inverter

The StecaGrid 20000 3ph and 23000 3ph is a three-phase solar inverter without a transformer,
which has a particularly high efficiency at any operating point and is suitable for the connection of a
PV generator with a power of 21.6 kW and 25.8 kW. Heat is dissipated only by convection, with an
internal temperature monitor protecting the device against exceeding the permissible ambient tem-
perature. The inverter is designed such that the device does not have to be opened for assembly
and connection work. All electrical connections are exclusively made with lockable connectors. The
device features an integrated DC isolating switch according to EN 60947-3, which considerably
reduces the overall installation work. The inverter provides the usual communication interfaces
RS485 and Ethernet. An illuminated graphical display shows the development of the feed power
and other operating data in a clearly arranged manner. An 8-key control panel below the display
provides excellent and comfortable control and navigation features. Based on its design in protec-
tion class IP65, the inverter can be installed at almost any outside location.
