UTF Report

Photovoltaic plants with power above 20 kW that self-consume a part of the electricity produced (Memorandum 17/D dated 28 May 2007 from the Customs Agency: implementing provisions of Legislative Decree No. 26/2007) have the obligation to report the opening of the power station.

The opening of a power station involves the obligation to install meters for the determination of electricity produced and sold to the network. The meters must be certified, calibrated and sealed in place by an approved laboratory in the presence of the power station manager (a person indicated in the statement as the representative of the power station) and a technician of the Customs Agency (former Finance Technical Department, UTF). A production record (daily recording of the meter covered by the UTF documents) is needed and this record must be reported monthly to the Customs Agency.

The MaxBox Solar system, linked to production counters or network analyzers / energy counter, automatically generates UTF reports required by the Customs Agency and can be downloaded in various electronic formats:

  • .docx (Microsoft Word)
  • .pdf (Acrobat)
  • .rtf (compatible with many text editors such as Microsoft Word)
  • .odt (Open Office)

The report can be generated with both the daily details of production (as required for facilities in Medium Voltage ) and by including the details of the F1, F2, F3 time slots (as required for facilities in Low Voltage).

Report generation can be performed accurately by capturing data directly from the fiscal counter, or in a less rigorous way by using a network analyzer or the sum of the power supplied by the inverters.

To acquire the data from the fiscal counters, the MaxBox Solar can be connected to the RS485/Modbus counter interface, if available, or to the ‘S0′ interface of the counter with the insertion of an impulse counter (e.g. Countis Eci2); Alternatively, it can be used as a MaxEye optical interface that converts the optical signals of the two LED into electrical signals that can be connected directly to a PLC or pulse counter modules (UTF Kit). This often proves to be the most effective and less expensive solution, with immediate installation times that do not require the intervention of technicians.
