Intellectual Property India Publishes Patent Application for 'Inverter System And Method For Operating Said Inverter System' Filed by Fronius International Gmbh

MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202517032767 A) filed by Fronius International Gmbh, Pettenbach, Austria, on April 2, for 'inverter system and method for operating said inverter system.'

Inventor(s) include Graf, Johannes; and Rechberger, Philipp.

The application for the patent was published on May 30, under issue no. 22/2025.

According to the abstract released by the Intellectual Property India: "The present invention relates to an inverter system (INV) for a photovoltaic system and to a method for operating the inverter system (INV). The inverter system (INV) comprises an inverter unit (WE), upstream of which a defined number of DC-to-DC converters (B1, ..., B4) is connected by means of an intermediate circuit (ZK). The DC inputs (DC1, ..., DC4) of the inverter system (INV) are formed by the DC-to-DC converters (B1, ..., B4), which define the number and properties of the DC inputs (DC1, ..., DC4). The DC inputs (DC1, ..., DC4) are connected to different direct-voltage units (PV1, PV2, BAT, EC, GE, VB), in particular PV units, energy storage units, etc. A switching unit (SE), which has inputs (E1, ..., E6) for connecting the direct-voltage units (PV1, PV2, BAT, EC, GE, VB), is connected to the DC inputs (DC1, ..., DC4). The switching unit (SE) is thus located between the DC-to-DC converters (B1, ..., B4) forming the DC inputs (DC1, ..., DC4) and the direct-voltage units (PV1, PV2, BAT, EC, GE, VB) which can be connected to the switching unit. The different direct-voltage units (PV1, PV2, BAT, EC, GE, VB) connected to the inputs (E1, ..., E6) are identified (101, 102), and for each direct-voltage unit (PV1, PV2, BAT, EC, GE, VB) connected to an input (E1, ..., E6) of the switching unit (SE) a present value of at least one power variable is determined (103). The determined present value of the at least one power variable is then compared with at least one defined threshold value (104). According to a relevant comparison result, the switching unit (SE) then establishes a connection between the connected direct-voltage unit (PV1, PV2, BAT, EC, GE, VB) in question and at least one suitable DC input (DC1, ..., DC4) and/or adapts the connection (105)."

The patent application was internationally filed on Nov. 07, 2023, under International application No.PCT/EP2023/081009.
