A metering and control subsystem for a photovoltaic solar system is configured for metering the photovoltaic solar system using current measurement devices and individually controlling relays to selectively energize photovoltaic branch circuits. In some examples, the metering and control subsystem includes photovoltaic branch connectors, a relay matrix, current measurement devices, and a metering and relay control circuit. The metering and control circuit is configured for metering the photovoltaic solar system using current measurement data from the current measurement devices and individually controlling the relays to selectively energize each photovoltaic branch circuit.

Metering and control subsystems for photovoltaic solar systems

Methods, systems, and computer readable media are disclosed for monitoring electric systems for wiring faults. In some examples, a system includes a production power meter coupled to a power generation system of a building and configured for measuring electric power generated by the power generation system, one or more consumption power meters coupled to an electric system of the building and configured for measuring electric power consumed by the electric system, and a computer system coupled to the production power meter and the consumption power meters. The computer system is programmed for determining that at least one power meter is installed with a reversed polarity that is reversed with respect to an installation specification, resulting in the computer system receiving measured values from the at least one power meter having an incorrect sign.

Monitoring electric systems for wiring faults

Solar roof mounting surface transition

A solar power system may include rails, solar modules, and a plurality of clamps to secure the solar modules to the rails. An end clamp may be partially disposed inside a rail at an end of the rail. The end clamp may secure a solar module to the rail by coupling to the frame of the solar module. The end clamp may include a fastener that may be tightened to engage the end clamp and secure the solar module by holding it on top of the rail. The end clamp may establish an electrical grounding connection between the frames of the solar module and the rail.
