Systems and methods for automatically or remotely rendering a solar array safe during an emergency or maintenance. A watchdog unit is disclosed for monitoring a signal from a central controller. If the signal is lost, interrupted, or becomes irregular, or if a shutdown signal is received, then the watchdog unit can shut down one or more solar modules. Shutting down a solar module can mean disconnecting it from a power bus of the solar array or lowering the solar module voltage to a safe level.

Systems and methods for an enhanced watchdog in solar module installations

A system includes a modulator configured to generate a communication signal whose modulation represents coded information to be transmitted to a local management unit connected to a photovoltaic module. A local management unit is configured to receive a communication signal whose modulation represents coded information from an inverter or a transmitter. The local management unit is configured to receive a unique pairing sequence; pair to a first transmitter or inverter; and receive communications from the first transmitter or inverter. The local management unit is configured to ignore communications from a second transmitter or inverter that is not paired to the local management unit.

Solar panel transmitter pairing process

A system and method for automated shutdown, disconnect, or power reduction of solar panels. A system of solar panels includes one or more master management units (MMUs) and one or more local management units (LMUs). The MMUs are in communication with the LMUs with the MMUs and LMUs 'handshaking' when the system is in operation. The MMUs are connected to one or more controllers which in turn are connected to emergency detection sensors. Upon a sensor detection of an emergency, the associated MMU is notified which in turn instructs associated LMUs to take appropriate action. In the event that communication with the MMUs has been cut off, the LMUs take the initiative to shut down, disconnect, or reduce the output of associated string(s) of solar panels.

System and method for enhanced watch dog in solar panel installations

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 system and method for precise and consistent control of automated systems for deployment of boat fenders. The system comprises a computing device, one or more sensors, a motor controller, and a motor driver for operating motorized systems for deployment and/or retrieval of boat fenders. Various embodiments of the system use sensors and corresponding compensators to adjust the time of operation of a motor of the motorized system to ensure that the boat fender is deployed and/or retrieved to the proper height.

System and method for controlling motorized boat fender deployment and retrieval systems

System and method for controlling motorzied boat fender deployment and retrieval systems

A photovoltaic system, including: a plurality of photovoltaic panels having outputs connected in series as a string to provide a string output; a converter coupled to the string to receive the string output as an input and generate a direct current output from the input; a series connection of the string output and the direct current output; and a bus powered at least in part by the series connection of the string output and the direct current output.

Enhanced system and method for string balancing

Systems and methods for removing charge buildup/leakage from solar modules. A discharge controller may be coupled between a solar module and a string bus of a solar array. The discharge controller is configured to disconnect the solar module from the string bus, and to connect a grounded frame to solar cells of the solar module. Since the grounded frame of the solar module is grounded, connecting the grounded frame and the solar cells allows charge buildup/leakage to discharge into ground.
