A multi-inverter system with at least a string of inverters sharing a DC bus and outputting to a shared AC bus. Inverters are hot-swappable and configured to be turned on or off during powered cycles. Central control may comprise reducing power point tracking redundancies or promoting other operational changes at individual inverters of a group.

Inverter coupling and decoupling management

Solar tracker systems having several rows of photovoltaic strings individually actuated by respective tracker control systems, are described. In an example, a solar tracker system includes a tracker control system having a tracker controller powered by forward-fed power from a photovoltaic string, e.g., during daytime, and powered by back-fed power from a station hub, e.g., during nighttime. Methods of operating the solar tracker system to forward-feed or back-feed power to the tracker control system are also described.

A solar collection system may collect energy from the sun to generate electricity for distribution on an electrical grid. In addition to generating electricity, a solar collection system may include support devices such as motors, controllers, sensors, and other support devices to perform various tasks to allow the solar collection system to more effectively generate electricity. When the solar collection system is generating sufficient power, the support devices may be powered by the solar collection system. However, when the solar collection system is not generating sufficient power, the support devices may be powered by a backfeed power supply circuit coupled to the electrical grid.
