Energy efficiency measures – Major repairs with the introduction of alternative energy systems and thermal modernization of the Dergachiv Lyceum No. 3 educational institution of the Dergachiv City Council
Phased implementation of energy efficiency measures – Major repairs with the introduction of alternative energy systems and thermal modernization of the Dergachiv Lyceum No. 3
In order to save energy, the project provides for the installation of a photovoltaic system consisting of photovoltaic modules (PEM) - 144 modules with a nominal power of 435 W each on the roof of the building, one hybrid three-phase inverter with a capacity of 50 kW and a high-voltage battery of 50 kWh, 512 V. The photovoltaic system equipment (except for photovoltaic modules) is installed in the electrical switchboard on the first floor. The photovoltaic system provides power to existing consumers in ON-Grid mode through a hybrid inverter. The use of a hybrid inverter allows for continuous power supply of some consumers in OFF-Grid mode from photovoltaic modules, from a battery or (in case of insufficient generation of the photovoltaic system and depletion of the battery charge) from the main network. The hybrid inverter charge controller provides support for the battery charge. Photovoltaic modules (a total of 144 modules) are connected in several strings for optimal power distribution. The connection of the modules in the string is carried out sequentially using a copper single-core wire of the H1Z2Z2-K 1x6 type. The photovoltaic modules are installed on the roof of the building. In order to ensure uninterrupted power supply to the shelter, the project provides for the installation of a system consisting of a Kon-TEC 10 kW inverter charger and a Kon-TEC MANA 16.0 battery - Low-voltage LiFePO4 energy storage battery of 16.07 kWh. Voltage: 51.2 V (nominal). The equipment is installed in the electrical switchboard room (shelter). All metal non-conductive parts of electrical equipment that may be under voltage must be connected to a grounding device (PE conductor). Such parts include: metal housings of electrical equipment, metal parts of ventilation equipment, metal housings of luminaires, metal pipes of communications, metal parts of the building frame, etc. The metal parts of the photovoltaic module mounting system and the cable retention system on the roof are connected to the lightning arrester grid using a round aluminum conductor d6 mm. The inverter is protected from secondary lightning strikes by designed surge arresters installed in the RSh2 DC panel on each input from the PV module.
