Batteries

One of the locations where the KSTAR KAC50DP-BC100DE system was implemented is the area near the State Forests in Spala, Poland. This location often experiences power outages, which poses a significant risk to the operation of key equipment such as electronically controlled water pumps. Implemented Solution: • KSTAR Battery Storage: KAC50DP + BC100DE + STS100D • Operating Modes: ON-GRID + OFF-GRID • Integration with photovoltaics to maximize self-consumption • Diesel Generator as Additional Backup Thanks to the KSTAR inverter, the system enables efficient energy management and ensures availability during power outages. The STS100D transformer switch works seamlessly with the PV inverters, and excess energy remains stored and ready for use in emergency situations.

A representative office of a world leader in the automotive industry required a solution that would ensure uninterrupted power supply in one of its service centers. Inefficient energy management in such a large facility can lead to unnecessary financial expenses. Therefore, it is necessary to implement a system that ensures effective management of surplus energy production and consumption. Implemented solution: • System configuration: 2x KAC50DP + 3x BC100DE + EMS01D • Operating mode: ON-GRID • Integration with an existing photovoltaic system that previously fed excess energy back into the grid under unfavorable conditions. • Self-consumption priority, allowing the facility to maximize the use of its own energy The service center faced challenges with restrictions on the purchase of energy from photovoltaics. By implementing KSTAR ESS energy storage systems, the company was able to focus on its own consumption and effectively manage energy 24 hours a day. The new system minimizes operating costs and ensures a stable energy supply during production processes.

KSTAR – Efficiency and Savings A modern photovoltaic installation was launched near the Skopje airport to support the energy needs of a modern cold storage warehouse that stores a large volume of food products. In order to optimize the coverage of energy needs, a 737 kWp photovoltaic installation was implemented with KSTAR KAC50DP hybrid inverters, which provide a total output of 700 kW and operate in parallel in 14 units. Each inverter manages a dedicated energy storage unit with a capacity of 100 kWh, resulting in a total storage capacity of 1.4 MWh. This design allows for maximum use of renewable energy and ensures energy stability of the refrigeration plant, even during peak demand periods when electricity prices are highest. Optimizing energy consumption and preventing losses The KSTAR energy storage system not only compensates for evening energy consumption, but also allows for the efficient management of surplus energy generated by photovoltaic modules. This prevents the sale of excess energy at disadvantageous prices, thereby increasing the overall profitability of the facility. To further optimize the system's performance, an intelligent energy management system is being implemented that analyzes electricity prices on the market in real time. This system will allow for the storage of energy generated from sunlight, as well as the purchase of electricity during periods of low prices, which can later be used for internal consumption or resold at higher market values. Tangible benefits of implementing KSTAR technology The use of KSTAR hybrid inverters has enabled the cold storage facility to cover up to 50% of its energy needs exclusively through renewable energy sources. As the project manager responsible for the implementation emphasized, the deployment of the energy storage system not only supports sustainability goals, but also significantly reduces operating costs. By intelligently managing energy that would otherwise be returned to the grid, this investment ensures a short payback period and long-term savings. This combination of environmental and economic benefits makes the KSTAR solution a key part of the modern energy transformation.
