FAQ
Frequently asked questions
What type of energy storage systems do you offer?
KonJa provides a full range of commercial and industrial energy storage solutions, including air-cooled and liquid-cooled lithium battery systems, modular cabinet ESS, containerized BESS and integrated hybrid inverters.
Do you support OEM / ODM and custom integration?
Yes. KonJa provides both OEM and ODM, including customized container energy storage systems tailored to your capacity, configuration and branding requirements.
Are your systems certified for the European grid?
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 or liquid-cooled — which should I choose?
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, longer cycle life and higher density — preferred for larger C&I and utility-scale projects.
What cycle life and warranty do your systems offer?
Our containerized systems are rated for 8,000+ cycles at 80% depth of discharge. Warranty terms (years and energy throughput) are confirmed per product and project — contact us for the datasheet.
Do you provide delivery and after-sales support in Europe?
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.
