Abstract: A current sensor device (10), a system (22), and a method for determining an electric power fed through a conductor (12) is proposed. The current sensor device (10) comprises a current sensor (14) adapted for determining an analog current signal of a current supplied through the conductor (12), a bus interface (16) adapted for receiving via a data bus (28) at least one digital voltage parameter of a voltage at the conductor (12), and a controller (18) adapted for converting the determined analog current signal into digital current values. Therein, the controller (18) is adapted for determining digital voltage values based on the at least one digital voltage parameter, and for calculating a power value based on the digital current values and the digital voltage values and/or energy values based on the power values.

Abstract: A box (SCB1) for combining n strings or m arrays of a DC part of a PV plant comprises a plurality of n DC inputs (21, 22, 23, 24) for electrical connection to the n strings or to a plurality of m DC inputs for electrical connection to the m arrays, at least n or m DC direction sensors for detecting the direction of direct currents (I S1 , I S2 , I S4 , I R ) conducted in the n or m DC inputs (21, …, 24) and a combiner control unit (SCCU). The DC direction sensors communicate their output signals to the combiner control unit. The combiner control unit communicates a first tripping signal to first switching units associated to the DC direction sensors for opening n-1 or m-1 of the n or m pairs of first switching units in order to interrupt the direct currents (I S1 , I S2 , I S4 ) between each of n-1 or m-1 DC inputs (21, 22, 24) and the two busbars when in a remaining one (23) of the DC inputs the direct current changes from a forward (I S3 ) to a first reverse current (I R ). This allows a fast localization and removal of a faulty string or array without any remarkable interruption of the PV plant and with small-sized switching units, typically with hybrid breakers. Thus the PV plant is distinguished by a high yield rate and a high reliability and can be installed and operated in a cost-efficient manner. Furthermore for reason of the small-sized switching units the combiner box can be realized as rail arrangement with a plurality of box-shaped modules which are attached to the rail arrangement.
