Abstract: A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.

Abstract: In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

Abstract: Systems and methods for managing flow batteries utilize a battery management controller (BMC) coupled between a flow battery and a DC/DC converter, which is coupled to an electrical grid or a photovoltaic device via an inverter. The inverter converts an AC voltage to a first DC voltage and the DC/DC converter steps down the first DC voltage to a second DC voltage. The BMC includes a first power route, a second power route, and a current source converter coupled to the second power route. The BMC initializes the flow battery with a third DC voltage using the current source converter until a sensing circuit senses that the voltage of the flow battery has reached a predetermined voltage. The sensing circuit may include a capacitor, which has a small capacitance and is coupled across each cell of the flow battery, coupled in series between two resistors having very large resistances.

Abstract: A solar tracking system is provided and includes a solar array, a plurality of support beams configured to support the solar array, a torque tube coupled to the plurality of support beams, a base configured to rotatably support the torque tube, and an articulation system configured to rotate the torque tube relative to the base. The articulation system includes a first helical tube coupled to the torque tube, a first helical tube support disposed on the base and configured to slidably support the first helical tube, and a gearbox in mechanical communication with the first helical tube. Actuation of the gearbox causes the first helical tube to translate within the first helical tube support and the first helical tube support is configured to rotate the first helical tube as the first helical tube is translated therein to cause a corresponding rotation of the solar array.
