CTECHI’s Marine Energy Storage System (ESS) delivers a comprehensive and sustainable power solution tailored for maritime applications. Utilizing automotive-grade LiFePO4 batteries, the system offers unparalleled safety, efficiency, and durability, making it the ultimate choice for boaters seeking to enhance performance while reducing environmental impact. With intelligent EMS integration and multiple charging options, this system provides seamless operation and an enjoyable sailing experience without the noise, fumes, or maintenance associated with traditional lead-acid batteries.
Powered by automotive-grade LiFePO4 cells, the Marine ESS ensures ultra-safe operation with high thermal and chemical stability. Its robust design resists vibrations and shocks, making it ideal for rough maritime environments.
Equipped with three fast and efficient charging options—alternator during cruising, solar panels, and shore power—the system guarantees a consistent and reliable energy supply for all onboard needs.
Integrated with an intelligent EMS, the system allows real-time monitoring and remote control of solar power generation, battery SOC (State of Charge), and power consumption via mobile devices, ensuring effortless energy optimization.
Designed to reduce fuel consumption and eliminate regular maintenance, the Marine ESS is maintenance-free and delivers a long runtime, minimizing operating costs while supporting sustainable sailing.
