Required System Components (Sold Separately):
To operate as a complete energy storage solution, the Deye BOS-B 215 kWh High-Voltage Battery System must be integrated with the following Deye system components, which are not included and are sold separately:
125 kW Power Conversion System (PCS) – required for DC-to-AC power conversion and battery charge/discharge control
200 kW MPPT Solar Charge Controller – required when integrating solar PV generation
500 kW Static Transfer Switch (STS) – required for seamless grid-to-backup power transfer and critical load support
These components work together with the battery system to form a fully functional high-voltage hybrid energy storage system.
