An integrated metering device allows a resource provider to control the output of a distributed generation device onto a resource distribution network or grid. The integrated metering device may include a communications module, a metrology module, an inverter and regulator device, and a transfer switch. A resource provider may communicate with the integrated metering device via the communications module and may control the inverter and regulator device or the transfer switch. The metrology module may monitor the energy provided by the distributed generation device to the grid and may send information about the generated energy to the resource provider via the communications module.

A system includes a control circuit and a computer. The control circuit includes a control circuit configured to receive data from at least one solar panel, convert the received data according to a communication protocol, and forward the converted data via the communication protocol. The computer includes software that, when executed by the computer, causes the computer to receive, via the communication protocol, the converted data, detect, based on the received converted data, a problem in the at least one solar panel, and output, to a display and based on the detected problem, a status of the at least one solar panel corresponding to a time at which the data was collected.

In some embodiments, a load power monitoring system includes a distribution board to distribute a electric power applied from a external electric power supply source or a first renewable energy source to an electric device, at least one power metering device to sense electric energy of at least one of the electric power supply source and the first renewable energy source, a second power metering device to sense electric energy distributed to the electric device, a third power metering device to sense electric energy generated from a second renewable energy source, and a monitoring server to collect electric energy data sensed at each of the power metering devices and monitor the load power based on the collected electric energy data.

A system for monitoring and wirelessly transmitting solar array parameters such as current, voltage and temperature in real time is primarily housed within a recombiner box. The system lends itself to retrofitting within some commercially available recombiner boxes. Signals emitted from the RF controller component of the system are received by a central processor, which includes a dashboard interface. Multiple systems in proximity can be linked to form a mesh network with one central processor.

A power converter circuit includes a monitoring module that monitors a DC power source, the monitoring module comprising a microcontroller. The power converter circuit also includes a temperature sensor providing temperature data to the microcontroller. In response to an indication from the temperature data of a failure or a problem, the microcontroller changes a parameter of the power converter circuit.

In some embodiments, the power monitoring system includes: a sampling device configured to measure patterns of energy consumed by loads included in the power system; an electric meter configured to measure an amount of second energy supplied from a system to the power system; a power supply configured to supply power stored therein or generate power to supply the power system and measure an amount of third energy supplied; and an external server configured to receive at least one of the patterns, the amount of the second energy and the amount of the third energy and analyze the patterns to acquire an amount of first energy for each of the loads. In some embodiments, the external server calculates at least one of the amount of the first, second and third energy.

A monitoring system and method for monitoring performance of individual powers sources in a distributed power source system. A monitoring module is coupled to each of the power sources, or to each string of serially connected power sources, to monitor and collect data regarding current, voltage, temperature and other environmental factors at the power source. The collected data is transmitted over a power line to a central analysis station for analysis. Data collected from each source indicates malfunction or degradation at the source. Comparison of data collected from adjacent sources filters for environmental factors impacting neighboring sources such as cloudy days for a solar panel. Comparison of data collected from the same source at different times indicates soiling or degradation of the source with time or periodic events such as a moving shade from an adjacent building.

Disclosed embodiments relate to a power monitoring system. In some embodiments, the power monitoring system includes: a sampling device configured to measure patterns of how loads included in the power system consume energy; an electric meter configured to measure a first amount of energy supplied from a transmission system to the power system; a power supply configured to supply power stored therein or generate power to supply it to the power system, and measure a second amount of energy supplied to the power system; an external server configured to receive measurements of the patterns from the sampling device, and obtain a third amount of energy consumed by the loads based on the measurements; and a home server configured to receive the first amount of energy and/or second amount of energy and transmit/receive data to/from the external server.
