S-ESS StackedLithium Battery Energy Storage System
Product Overview
The S-ESS Stacked Lithium Battery Energy Storage System is a highly efficient, flexible, and safe energy storage solution for various applications. Its modular design allows for easy stacking, enabling users to flexibly expand capacity from 10.24kWh to 512kWh by connecting battery modules in series or parallel. This not only simplifies installation and transportation but also facilitates future maintenance and upgrades.
Powered by high-performance lithium iron phosphate batteries, it offers an extended cycle life of over 6,000 cycles, ensuring long - term stable performance. A 51.2V system typically operates within 43.2V - 57.6V, with standard charge and discharge currents varying based on module configurations.
Equipped with an advanced Battery Management System (BMS), it constantly monitors parameters like SOC, voltage, current, and temperature to guarantee safe operation. Multiple safety features, including fire, explosion, and leakage protection, as well as high IP ratings (e.g., IP55/IP65), adapt to diverse environments.
With communication options such as RS485, CAN, WiFi, and Bluetooth, it enables seamless connectivity. Remote monitoring and control via mobile apps allow users to manage the system in real - time. Ideal for home solar storage, it stores excess daytime solar power for later use, reducing electricity costs. In commercial settings, it supports load shifting and serves as emergency backup, optimizing energy efficiency and cutting expenses.
