A system, comprising a solar circuit (2), a coupling circuit (1), a converter circuit (5), a source circuit (3), and a load circuit (4), wherein the coupling circuit (1) couples in a first, charging mode the solar circuit (2) to the source circuit (3) via the converter circuit (5) and couples in a second, feeding mode the source circuit (3) to the load circuit (4) via the converter circuit (5). A power flow through the converter circuit (5) has a same direction in both modes. In the first mode, a charging current is guided from the solar circuit (2) to the source circuit (3) via the converter circuit (5) for charging the source circuit (3). In the second mode, a feeding current is guided from the source circuit (3) to the load circuit (4) via the converter circuit (5) for feeding the load circuit (4). The coupling circuit (1) may comprise a first switch (11) and a second switch (12) and a control circuit (13-21) for controlling the first and second switches (11, 12). The control circuit (13-21) may comprise generators (13, 15), a comparator (14), detectors (16, 17, 19), a manager (18) and a regulator (20). |
