Brightway Solar Electricity Store 500KWH Container Energy Storage System

  • BWS-ESS250KT

  • Brightway Solar


Function Characteristics

On the DC side, the system incorporates BYD's automotive-grade modular lithium iron phosphate battery energy units. Lithium iron phosphate batteries are known for their high safety, long lifespan, and environmental friendliness. These batteries are modular, meaning they can be easily scaled up or down based on the system's energy storage requirements. Additionally, BYD's original BMS (Battery Management System) protection ensures optimal battery performance and safety by monitoring crucial parameters like voltage, temperature, and current. This BMS also includes safety features like overcharge and over-discharge protection, ensuring the batteries operate within their safe limits.
