3.1 Description of the Device
The REFU
sol
®
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 8.8kW up to 21.2 kW. Heat is dissipated only by convection, with an internal temperature monitor
protecting the device against exceeding the permissible ambient temperature. The inverter is de-
signed 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 inte-
grated DC isolating switch according to EN 60947-3, which considerably reduces the overall instal-
lation 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 com-
fortable control and navigation features. Based on its design in protection class IP 65, the inverter
can be installed at almost any outside location.
