A full range — 50–125 kW C&I cabinets (air- and liquid-cooled), 500 kW–1.5 MW all-in-one containers, 3.44–5.015 MWh DC blocks, 3.45–5 MW boost-integrated stations, and 30/50 kW SiC hybrid inverters — covering commercial & industrial, utility-scale and PV self-consumption applications.
Yes. KONJA provides both OEM and ODM, including customized container energy storage systems tailored to your capacity, configuration and branding requirements.
Yes. Our 261 kWh system is certified to the Italian grid codes CEI 0-16 and CEI 0-21 by TÜV NORD, and our products carry IEC 62619 (battery safety) and IEC 62477 (PCS safety) from TÜV SÜD.
Air-cooled systems are simpler and lower-cost, well-suited to residential and small C&I sites. Liquid-cooled systems deliver about 40% better heat dissipation, tighter temperature control (3 °C cluster spread), longer cycle life and higher density — preferred for larger C&I and utility-scale projects.
Our containerized systems are rated for 8,000+ cycles at 90% depth of discharge. Warranty terms (years and energy throughput) are confirmed per product and project — contact us for the datasheet.
Yes. KONJA operates branch offices and warehouses in Germany, the Netherlands and the Czech Republic for fast, reliable lead times and local support, with 1,200+ projects delivered across Europe, the Middle East, Australia and Southeast Asia.
