Beschreibung
Zusammenfassung:	A self-powered electronic shelf label (ESL), comprising: a processing circuitry; a display communicatively coupled to the processing circuitry; a communication circuit communicatively coupled to the processing circuitry, wherein the communication circuit is configured to receive and transmit data from a control device; and a power manager connected to the processing circuitry, the display, an energy storage, and a plurality of photovoltaic (PV) cells, the power manager including a maximum power point tracker (MPPT) circuit, wherein the MPPT circuit is configured to continuously determine a maximum power point of the PV cells, wherein the power manager is configured to connect, based on the determined maximum power point, at least a portion of the plurality of PV cells to a load such that the plurality of PV cells produce a voltage equal to the continuously determined maximum power point.
