LaserTec FullSet Monolith 265 energy storage system

LaserTec FullSet Monolith 265 industrial energy storage system was built by LaserTec S.A. in Poland in 2023. This highly advanced machine is a key component of a company’s strategic energy management. It allows the storage and management of electricity at the most cost-effective times, bringing tangible savings to the company. The system also plays an important role in stabilising and reducing overloads on the local network, which is particularly important in industrial plants where the continuity of production processes is critical to maintaining operational fluidity.

The FullSet Monolith 265.50h energy storage system accumulates electricity from both photovoltaic installations and the grid. The battery modules made of NMC lithium-ion cells are characterised by timeless durability. Off-grid operation, on the other hand, provides emergency power in the event of power cuts. This solution gives companies energy independence through uninterrupted access to energy, regardless of the market situation or weather conditions. The LT PowerBox energy storage system weighs approximately 3100 kg.

The offer also includes the BSI50HF-02LT bi-directional AC/DC power conversion system, made with SiC technology. Equipped with galvanic isolation and a high-frequency transformer (25 kHz), the unit allows active and reactive power to be controlled, as well as charging and discharging battery banks to the grid.
