NOVELTY - A device comprises a housing; power distribution blocks mounted in the housing for combining utility-compliant alternating current from inverters (5), carried over wires (6) containing monitoring signals from the inverters; noise filters tuned to block interference with the first monitoring frequency, between the power distribution blocks and the utility connection; and a power outlet box (7), where the noise filters reduce cross talk from other monitoring signals from other inverters, and noise from devices using the alternating current from a utility grid (10).    USE - A device used for photovoltaic system.    ADVANTAGE - The device reduces or eliminates noise, and crosstalk interference with household electronics and energy monitoring devices. It has improved troubleshooting functionality, and allows consumers to independently verify amounts of electricity provided by a utility company.    DETAILED DESCRIPTION - A device comprises:    (A) a housing;    (B) power distribution blocks mounted in the housing for combining utility-compliant alternating current from inverters (5), carried over wires (6) containing monitoring signals from the inverters at a first monitoring frequency, to provide combined alternating current carrying the monitoring signals, where the combined alternating current is connected in parallel with alternating current from a utility grid (10) at a utility connection to trigger the inverters to produce the utility-compliant alternating current, and the combined alternating current feeds power to the utility grid and a local load (8) connected to the utility connection;    (C) noise filters tuned to block interference with the first monitoring frequency, between the power distribution blocks and the utility connection; and    (D) a power outlet box (7) having greater than or equal to 2 outlets electrically connected to one of the power distribution blocks, where a solar energy monitoring device can be plugged in one of the outlets and an internal Ethernet bridge adapter that is connected to the Internet can be plugged into another of the outlets, where the solar energy monitoring unit and the internal Ethernet bridge adapter can be connected for data transfer, where the power distribution blocks provide the combined alternating current to the solar energy monitoring device which extracts the monitoring signals as extracted monitoring signals, and where the internal Ethernet bridge adapter connected to the solar energy monitoring device communicates the extracted monitoring signals at a second monitoring frequency to a remote external Ethernet bridge adapter connected to a remote server; where the noise filters reduce cross talk from other monitoring signals from other inverters, and noise from devices using the alternating current from the utility grid.
