Brightway Solar 500kWh To 1MWH Industrial Solar Energy System Off Grid Solar Power System


  • Brightway Solar


Function Characteristics

  • The 250KW/500KW and 250KWH/500kWh-1.2MWH outdoor 20-foot containerized Energy Storage System (ESS) is designed for extensive application in large-scale commercial and industrial energy storage projects. At its core, the DC side incorporates BYD's vehicle-grade modular lithium iron phosphate battery energy units, coupled with BYD's original Battery Management System (BMS) for robust protection. On the AC side, it leverages Brightway Solar's series of hybrid solar inverters to ensure efficient energy conversion.

  • Guided by the advanced Energy Management System (EMS) operation strategy, this ESS seamlessly interfaces with the grid, promoting grid stability while providing crucial power backup for customers during periods of power scarcity. The integrated EMS also offers flexibility through multiple working modes, including self-consumption, peak load shifting, Time-of-Use (TOU) optimization, and battery priority, allowing users to tailor the system's performance to their specific needs.
