KOSTAL

KOSTAL Storage

KOSTAL is an established supplier of components for photovoltaic and energy systems with a focus on reliable, modular high-voltage battery systems. The HELIVOR HV family is characterized by high efficiency, robust battery management (BMS) and scalable capacities. Safety, long service life and easy integration into PV systems are among the key features. Applications range from private single-family homes to commercial properties and medium-sized commercial energy storage systems.

Storage solutions for PV systems

Storage systems are used for self-consumption optimization, load shifting and grid support. KOSTAL HV systems enable both space-saving residential storage and powerful commercial solutions through modular expandability. Advantages for project developers and installers include predictable capacities, simplified system integration with inverters and reduced installation times thanks to preconfigured modules. For operators this results in improved economics and increased energy security.

KOSTAL storage features

Technically, the systems are based on high-voltage lithium-ion technology with modular battery modules, an integrated BMS and communication interfaces for energy management. The focus is on high round-trip efficiency, cycle life performance and standards-compliant safety. The BMS provides cell monitoring, temperature management and fault shutdown; mechanical and electrical protection features increase operational safety. The modular architecture makes lifetime planning, maintenance and capacity expansions economically manageable.
