    Abstract: Apparatuses and methods are disclosed for regulating or limiting the voltage output from solar modules connected in series such that the voltage on a string bus connecting those solar modules does not exceed regulatory or safety limitations. This can be accomplished via a controller, local management units (for downconverting solar module voltage output), or a combination of the two.

    Abstract: 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.

    Abstract: Provided are a system and method 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.

    Abstract: 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).

    Abstract: Systems and methods to balance currents among a plurality of photovoltaic units connected in series. In aspect, a management unit is coupled between a photovoltaic energy production unit and a string of energy production units. The management unit has an energy storage element (e.g., a capacitor) connected to the photovoltaic energy production unit. The management unit further has a switch to selectively couple to the energy storage element and the photovoltaic energy production unit to the string. The management unit allows the current in the string to be larger than the current in the photovoltaic energy production unit.
