Abstract: A power system for connecting a power source, an energy storage unit and a grid includes a power inverter, an energy storage power converter and a controller. The power inverter is electrically coupled to the power source through a DC bus and converts DC power from the DC bus to AC power output to the grid. The power converter is electrically coupled between the DC bus and the energy storage unit and stores power in the energy storage unit and discharges power from the energy storage unit. The controller controls the power converter to store excess power from the power source that cannot be output to the grid in the energy storage unit, and control the energy storage power converter to discharge power stored in the energy storage unit to the power inverter to output to the grid.

Abstract: Solar power systems and structures are mountable to a power distribution structure, e.g. a power pole or tower, which supports alternating current (AC) power transmission lines. An exemplary power generation structure is fixedly attached to and extends from the power distribution structure, and comprises a mounting rack. A solar array, comprising at least one solar panel, is affixed to the mounting rack. A DC to AC inverter is connected between the DC outputs of the solar array and the AC power transmission lines. The length of the solar array is generally in alignment with the power distribution structure, and the width of the solar array is greater than half the circumference of the power distribution structure. The mounting rack and solar array may preferably be rotatable, such as based on any of location, time of day, or available light.

Abstract: A maximum power point tracking method includes: configuring a voltage tuning direction of a power converter by a process circuit such that the input voltage of the power converter changes in a positive or a negative trend; detecting the corresponding input voltage and input current of the power converter sequentially to obtain multiple powers; and when the powers decrease for N times continuously, change the voltage tuning direction of the power converter such that the change of the input voltage switches from positive trend to negative trend, or from negative trend to positive trend, in which N is an integer greater than or equal to 2.

Abstract: A power converter circuit includes output terminals configured to receive an external voltage. A series circuit with a number of converter units is connected between the output terminals of the power converter circuit. Each converter unit includes input terminals configured to be coupled to a DC power source and output terminals configured to provide an output current. At least one converter unit of the converter units includes a signal generator configured to receive a synchronization signal and to generate a continuous synchronization signal from the synchronization signal. The power converter circuit can be operated in a normal operation mode. In the normal operation mode, the at least one converter unit is configured to regulate generation of the output current such that a frequency and/or a phase of the output current are dependent on the continuous synchronization signal.

Abstract: A method for detecting a potential-induced degradation (PID) of PV modules of a PV installation, having a measurement pass, includes operating a PV generator of the PV installation at a maximum power point (MPP) with values of generator voltage (UMPP) and generator current (IMPP) associated with the maximum power point (MPP), and operating the PV generator of the PV installation at a first generator voltage (U1) and detection of a first generator current (I1) associated with the first generator voltage (U1). The method also includes operating the PV generator of the PV installation additionally at a second generator voltage (U2) and detection of a second generator current (I2) associated with the second generator voltage (U2), wherein the first generator voltage (U1) dictates that a first power (P1), with P1=U1*I1, of the PV generator at the first generator voltage (U1) is in a predefined first ratio (V1), with V1=P1/PMPP and V1≤1, with the power (PMPP) at the maximum power point (MPP) of the PV generator, and wherein the second generator voltage (U2) dictates that a second power (P2), with P2=U2*I2, of the PV generator at the second generator voltage (U2) is in a predefined second ratio (V2), with V2=P2/P1 and V2
