Public tender VOB/A Installation of a PV system approx. 240 kWp The magistrate of the city of Fulda has completed the new construction of the vehicle hall including the operational building and is now planning to install a photovoltaic system on it. B ... Multiple installation of a PV system approx. 240 kWp The magistrate of the city of Fulda has completed the new construction of the vehicle hall including the operational building and is now planning to install a photovoltaic system on it. The building is a functional building in the form of an angle structure with a central operational building and garages adjoining it to the left and right. The roof structure consists of glued beams with a foil roof. The operational building was built using a combined solid and wooden construction. The outer walls of the entire building complex were made with a wooden facade. A photovoltaic system with an output of currently 244.75 kWp and an east-west orientation is planned on the roof of the operational building. The voltage supply comes from the Nshv on the ground floor from a separate photovoltaic transfer field. The required protection technology and all other requirements must be coordinated with the grid operator. All necessary approvals must be obtained from the grid operator and the corresponding registrations must be made. Modules with an output of 445 Wp are used for the PV system. According to the model administrative regulation for technical building regulations 2020/1, modules with a maximum area of 2 m² must be used on roofs. The inverters are to be placed on the roof as currently known. Fire protection requirements and the existing fire walls must be taken into account. Requirements for a fire department shutdown must be coordinated with the responsible fire department. The PV system must be installed in accordance with DIN VDE 4110. AC cabling From the inverter to the sub-distribution for collecting the electrical energy, the cabling is carried out in accordance with VDE 0276 Part 603. Cables are used which are suitable for laying outdoors, i.e. they are ozone, UV and weather resistant. The cables are laid on routes and in the building or underground. The cables are laid to the inverter in cable routes/ladders made of dip-galvanized steel in accordance with EN ISO 1461 and are mounted on the substructure. Appropriate cable support must be ensured. The cables are to be laid in accordance with the circuit assignment so that, in addition to the electromagnetic effect, there is also a clear assignment of the cables. The cables in the area of the cable routes and KSV rails are to be secured accordingly using KSV clamps. Surge protection must be implemented at the building entrances in accordance with DIN VDE 0100-442/-534. Information Field 05 in the NSHV is used to feed in the PV system. The NA protection is installed here, as well as the necessary circuit breakers including all other components. The Q protection and the necessary UPS (8h) are housed in a separate switch cabinet in the NSHV. The current and voltage tap for the higher-level decoupling protection is in the medium voltage, which trips the grid-facing circuit breaker in the NSHV in the event of a fault. The voltage and current transformers in the medium voltage are to be replaced with 3-core transformers in the customer's own transfer station and the higher-level decoupling protection including accessories are to be retrofitted. The transformers must be agreed with the grid operator before installation and conformity must be confirmed. A distributor is provided for the EZA controller in the NSHV room. The higher-level decoupling protection sends the signal via a data cable to the EZA controller in the NSHV room. Furthermore, a meter cabinet is set up here as required, in which the transformer measurement of the photovoltaic system is set up. The transformer set is provided by the metering point operator and must be agreed with the responsible grid operator before installation. System certification is no longer required for the system due to the change in the law from May 8, 2024. Nevertheless, all necessary and relevant documents in accordance with VDE-AR-N 4110 must still be compiled and presented to the grid operator for inspection. This must be done by the AN-PV. The feed-in management and control of the system is carried out by the EZA controller. Data point lists must be exchanged and agreed between the grid operator, direct marketer and AN-PV. The connection to the grid operator is made via the EZA controller.
