Systems and methods for shut-down of a photovoltaic system. In one embodiment, a method implemented in a computer system includes: communicating, via a central controller, with a plurality of local management units (LMUs), each of the LMUs coupled to control a respective solar module; receiving, via the central controller, a shut-down signal from a user device (e.g., a hand-held device, a computer, or a wireless switch unit); and in response to receiving the shut-down signal, shutting down operation of the respective solar module for each of the LMUs.

Systems and methods for remote or local shut-off of a photovoltaic system

Apparatuses and methods include a solar array having one or more string buses of series-connected solar modules. The current outputs from the solar modules on each string bus can be balanced along with the voltage output from the string buses. Local management units coupled between the solar modules and the string buses are configured to control the voltage output from each solar module. When the solar modules on each string are balanced, and when the string buses are balanced (or before the solar modules and string buses are balanced), an inverter or other device connected to the solar array can find the array's maximum power point via a maximum power point tracking algorithm.

Systems and methods for local and master management units in a photovoltaic energy system. In one embodiment, a method implemented in a computer system includes sending a first identification code from a local management unit to a master management unit. The first identification code is associated with the first local management unit, and the local management unit controls a solar module. An authentication of the first identification code is received from the master management unit. In response to receiving the authentication, active operation of the local management unit is continued (e.g., for a set time period).

Systems and methods for an identification protocol between a local controller of a solar module and a master controller

Systems and methods for determining a connectivity topology of local management units (LMUs) in a solar photovoltaic power generation (SPVPG) system. Each of the LMUs is connected within the SPVPG between a solar panel and a set of power lines of the SPVPG. The set of power lines connects the LMUs to form a network. The connectivity topology of LMUs in the network is determined using, for example, indirect indications of connections of an LMU and the SPVPG and indications of the physical location of the LMU with respect to other elements of the SPVPG.

Systems and methods for local management units in a photovoltaic energy system. In one embodiment, a method implemented in a computer system includes: attempting to communicate on a first active channel with a master management unit from a local management unit that controls a solar module; if communication with the master management unit on the first active channel has not been established, attempting to communicate on a second active channel with the master management unit.
