Application Case of 50-150KW PCS in French Wineries

o The client is a winery with a reputation in the winemaking industry. The winery occupies a large area with modern winemaking workshops, cellars, office space and a large vineyard. With the continuous expansion of the winery business and the increasing requirements for production efficiency and energy management, its power system faces a series of challenges. The electricity supply from the grid in the region where the winery is located sometimes fluctuates, especially during the peak summer season when voltage instability occurs. This poses a potential threat to some of the equipment in the winemaking process that requires high power quality, such as sophisticated fermentation temperature control systems, automated filling lines, etc., which can lead to equipment failures, production disruptions, and wine quality impairment. The winery has extensive land resources and good conditions for solar energy development. However, due to the lack of effective power conversion and management equipment, it is difficult for wineries to fully utilize solar energy resources and seamlessly integrate them into the existing power system. The direct current generated by the simple installation of solar photovoltaic panels cannot directly meet the needs of various AC electrical equipment in the winery, and in the absence of suitable energy storage and power regulation devices, the intermittent power generation characteristics of solar energy also limits its large-scale application. To solve these problems, the winery chose ARK's 50-150KW PCS products to build an efficient energy management and power conversion system.

oARK PCS has a strong bidirectional power conversion capability and can respond quickly when the power grid is unstable. When the grid voltage fluctuates or drops, PCS can release electrical energy from the energy storage system (energy storage battery matched with the solar photovoltaic system) to supply power to key equipment in the winery with stable voltage and frequency, ensure the normal operation of fermentation temperature control system, filling production line and other equipment, and avoid wine production quality accidents caused by power problems. For example, during a summer peak, the local power grid voltage fluctuated by 10%, and ARK PCS intervened in time to stabilize the output voltage within the standard range, ensuring the continuous production of the brewing workshop.

As a bridge between the solar photovoltaic system and the AC power grid of the winery, oARK PCS can efficiently convert the direct current generated by the solar photovoltaic panels into AC power to meet the needs of various AC power equipment in the winery. At the same time, it can intelligently control the flow of electricity according to the solar power generation situation and the electricity load of the winery. During the day, when the sun is sunny and there is a surplus of solar power, PCS stores the excess energy into the energy storage battery. In the night or cloudy days when solar power is insufficient, PCS extracts electricity from the energy storage battery to supply power to the winery, realizing the full utilization of solar energy and uninterrupted supply of electricity. For example, the winery installed a solar photovoltaic system with a total power of 100KW, and through the optimized management of ARK PCS, the daily utilization rate of solar energy increased from less than 30% to more than 60%, greatly reducing the winery's dependence on traditional grid electricity.

oARK's solutions have revolutionized wineries. It not only solves the long-term problems of power quality and cost, but also makes full use of solar energy resources to achieve sustainable energy management.
