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

Methods and systems for connecting a photovoltaic module and an inverter having an input capacitor are presented. The photovoltaic system includes a maximum power point tracking (MPPT) controller coupled between the inverter and the photovoltaic module. The MPPT controller includes a direct current (DC) converter configured to reduce, in a forward buck mode, a voltage of the photovoltaic module, to supply power from the photovoltaic module to the input capacitor of the inverter. The photovoltaic system also includes a microcontroller unit (MCU) configured to control the DC converter to allow the photovoltaic module to operate at a maximum power point, and to increase, in a reverse boost mode, a voltage of the input capacitor of the inverter, to dissipate power from the input capacitor in the photovoltaic module, and the MPPT controller is configured to, based upon one or more triggers.

Systems and methods for quick dissipation of stored energy from input capacitors of power inverters

An arc detection and intervention system for a solar energy system. One or more arc detectors are strategically located among strings of solar panels. In conjunction with local management units (LMUs), arcs can be isolated and affected panels disconnected from the solar energy system.

System and method for arc detection and intervention in solar energy systems

A transmitter having: an oscillator to generate a clock signal and synthesize frequencies for modulating a message to generate first signals to a first direct current power line, and a control circuit to adjust timing of the first signals in synchronization with second signals transmitted in a second direct current power line disposed in a vicinity of the first direct current power line, by synchronizing phase of the first and second signals or by transmitting the first and the second signals in separate time windows.

Synchronization of signals transmitted over power lines

A cascading regulation system connected to a number of serially connected power sources and uses multiple regulators having different cutoff voltages to provide an output for the local power consumption unit. Each of the regulators is connected to a subset of serially connected power sources and so configured that if the voltage generated at the lowest tap is no longer sufficient for a stable supply to the local power consumption unit, the next higher regulator takes over, and the output voltage drops in small steps reflective of that takeover of the next higher tap. When the voltage generated across a subsection grows, a lower connected tap may take over again, producing a slightly higher output voltage for the local power consumption unit. The cutover steps are chosen such that the output voltage range matches the range given as the acceptable input range for the local power consumption unit.

System and method for low-cost, high-efficiency solar panel power feed

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).
