2 Description of LSPV inverter 010K to 020K
2.1 Description of the Device
The LSPV inverter 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 11kW up to 21.1 kW. Heat is dissipated only by convection, with an internal temperature
monitor protecting the device against exceeding the permissible ambient temperature. The LSPV
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 LSPV inverter provides the usual communication interfaces RS485, 230 V / 2
A AC relay (fault message), Ethernet, and USB. An illuminated graphical display shows the devel-
opment 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 protection class IP 65, the LSPV inverter can be installed at almost any outside
location.
