    Abstract: Systems, methods, and non-transitory computer readable media including instructions for an inverter for communicating power from a cluster of fluid turbines to an electrical grid. An inverter for communicating power from a cluster of turbines to a grid includes circuitry configured to receive via a rectifier associated with each turbine in the cluster, a DC voltage such that a plurality of DC voltages from differing turbines are received and aggregated; at least one processor configured to: confirm that a connection to the grid conforms with at least one operating parameter; when conformity of the grid connection with the operating parameter is confirmed, enable inversion of the aggregated DC voltage to an AC voltage compatible with the grid and enable output of the AC voltage to the grid; and when conformity of the grid connection with the operating parameter is not confirmed, prevent output of the AC voltage to the grid.

    Abstract: This disclosure describes many innovations including but not limited to systems, methods, and non-transitory computer readable media containing instructions for controlling an energy generator. A system for controlling an energy generator includes a detector for sensing an indicator of electrical energy generated by the generator; an energy storage component configured, in a first mode of operation, to store energy generated during operation at a sub-threshold level insufficient for real-time supply to an electrical energy sink; an energy converter configured, in a second mode of operation, to provide energy generated during operation above the threshold level for real-time supply of energy to the electrical energy sink; and a controllable switch, electrically associated with the detector, and configured to alternately toggle between the first mode of operation and the second mode of operation based on the indicator to thereby permit energy generated at the sub-threshold level to be collected and intermittently used.

    Abstract: Systems, methods, and non-transitory computer readable media including instructions for an aggregated voltage controller for a cluster of fluid turbines. An aggregated voltage controller includes at least one processor configured to: receive a target voltage for the cluster; receive via a plurality of rectifiers, each associated with a different turbine, an indication of a DC voltage associated with each turbine, wherein the DC voltage associated with at least one of the turbines is below the target voltage; and based on the received indications of the DC voltage signals associated with each turbine in the cluster, output a control signal to each of a plurality of DC-DC converters associated with the plurality of rectifiers, each control signal configured to regulate each DC-DC converter to produce a DC output at the target voltage such that combining each DC output in parallel produces an aggregated DC voltage conforming to the target voltage.

    Abstract: A support system may secure a wind turbine above an angled roof. The angled roof may have a first angled surface, an opposite second angled surface, and a peak between the first angled surface and the second angled surface. The support surface may have a first weighted ballast located along a portion of the first angled surface and a second weighted ballast located along a portion of the second angled surface. The support system may have a connector extending between and connecting a portion of the first weighted ballast and a portion of the second weighted ballast. The connector may extend over the peak. The support system may have a mounting portion on the connector for securing a wind turbine to the connector. The first weighted ballast and the second weighted ballast may be sized and weighted to maintain the wind turbine above the peak during wind conditions.
