Installation of a Photovoltaic System for the Mezőkövesd-Zsóry Bath

Installation of a photovoltaic system in the area of the Mezőkövesd-Zsóry bath (Napfürdő u.): Construction of a small power plant system not subject to licensing, based on the module count and power specified in the budget tender. The electricity generated by the inverters will be connected to the 0.4 kV main distributor feed-in connection points. The system must be designed with back-watt protection to limit grid feedback. Measurement points: Napfürdő u. 2 with an existing available power of 500 kW, connection value 3x800 A, and solar connection of 107.8 kW; Olajfa u. 1 with an existing available power of 100 kW, connection value 3x160 A, and solar connection of 383.7 kW. Electrical connection characteristics: Operating voltage 3F+N, 400 V, 50 Hz. The photovoltaic inverters are fed from the high-current distribution cabinets. Inverters: Total AC power of 499.5 kW, distributed as follows: 7 units, each with at least 25 kW nominal AC power; 6 units, each with at least 20 kW nominal AC power; 2 units, each with at least 17 kW nominal AC power; 3 units, each with at least 15 kW nominal AC power; 1 unit, at least 12.5 kW nominal AC power; 1 unit, at least 10 kW nominal AC power; 1 unit, at least 50 kW nominal AC power; 5 units, each with at least 8.2 kW nominal AC power; 1 unit, at least 7 kW nominal AC power; and 1 unit, at least 5 kW nominal AC power. Power distribution by location: Parking area 320.32 kW, swimming pool 63.36 kW, bath 81.08 kW, economic buildings and children's resort 117.88 kW. The system includes a total of 1,131 photovoltaic modules, each with at least 440 Wp nominal power, and 115 photovoltaic modules, each with at least 720 Wp nominal power. The photovoltaic modules, inverters, and associated electrical equipment to be installed must comply with the technical, safety, and performance requirements specified in the design documentation, technical description, relevant standards, and grid operator regulations. Reference to specific brands or types is avoided; an offer of a technically equivalent product is acceptable. The investment requires a building permit, further items as per the tender documents.
