???? Rugged & Reliable Design
Both the PCS and MPPT modules feature IP65 protection, ensuring long-term durability even in harsh environments. The BOS-B batteries are designed for stability and reliability, while the PCS module supports 110% overload capacity and instantaneous peak power up to 170%, offering superior performance under demanding conditions.

???? High Efficiency & Scalability
The PCS module delivers 98.5% maximum efficiency, while the MPPT module achieves over 99%, optimizing solar conversion and system performance. Up to 20 PCS units can operate in parallel, reaching 2.5MW total capacity, with each PCS supporting 16 battery clusters for up to 32 hours of backup power.

???? Intelligent Energy Management
Each BOS-B cluster includes an independent BMS for real-time monitoring, automatic balancing, and battery life extension. The integrated EMS eliminates the need for external controllers, supporting zero-export, time-of-use, and remote parameter adjustments via touchscreen or cloud access.

???? Fast & Reliable Switching
The 500kW STS module enables seamless transitions between on-grid, off-grid, and generator modes in under 10ms, guaranteeing uninterrupted power delivery. Each connection path — grid, diesel, and load — operates independently, providing maximum system safety and efficiency.

???? Advanced PV Integration
The MPPT module features a 200kW PV input with 8 MPPT channels, supporting up to 40A per channel and a wide voltage range (180–850V) for flexible and efficient solar input management.

The DEYE 125kW PCS 215kWh ESS combines high efficiency, intelligent control, and modular flexibility — delivering a future-ready energy storage solution for businesses that demand reliability, scalability, and total energy independence.
