Deye Unveils High-Efficiency C&I Power Conversion System with Integrated Storage

Chinese power electronics specialist Deye has launched a new Power Conversion System (PCS) + BOS-B energy storage solution tailored for commercial and industrial (C&I) solar+storage applications. The system combines high-efficiency solar conversion, flexible scalability, and seamless grid/generator backup—making it ideal for factories, data centers, and microgrids.

Key Features & Specifications

☀️ Solar Integration

✔ 200kW max PV input via 8x MPPT channels (40A each)
✔ Ultra-wide voltage range: 180-850V (1,000V system compatible)
✔ >99% MPPT efficiency – Minimizes energy loss

🔋 Battery Storage

✔ Modular LFP batteries: 14.3kWh per pack (up to 215kWh per cluster)
✔ 6,000-cycle lifespan – Long-term reliability
✔ Operating range:

• Charging: 0°C to 55°C

• Discharging: -20°C to 55°C

⚡ Power Conversion & Backup

✔ 100kW / 125kW PCS modules (scalable to 2.5MW)
✔ 98.5% efficiency | 170% peak power capability
✔ <20ms switchover between grid/off-grid/diesel modes
✔ Diesel generator support (up to 500kW connection)

🏭 Rugged Design

✔ IP65-rated PCS (dust/water resistant)
✔ IP20-rated battery enclosures

Why This System Stands Out

1. Unmatched Flexibility for C&I Sites

• Handles fluctuating energy demands with multi-mode switching

• Optimized for high solar self-consumption (reduces grid dependence)

• Diesel hybrid-ready for backup in off-grid/weak-grid areas

2. Cost & Space Efficiency

• Modular design allows right-sized deployments (no overbuilding)

• High MPPT efficiency maximizes solar ROI

3. Future-Proof Scalability

• Start small (100kW) and expand to 2.5MW+ as needed

• Battery clusters support growing storage needs

Target Applications

🏢 Manufacturing plants (peak shaving, backup power)
⚡ Data centers (uninterruptible power supply)
🌍 Microgrids & remote facilities (diesel hybrid optimization)
🔌 EV charging hubs (demand charge management)

Competitive Landscape

Compared to similar C&I systems from Sungrow, Huawei, and Growatt, Deye’s solution stands out with:
✅ Higher MPPT efficiency (99% vs. ~98%)
✅ Faster grid transition (<20ms vs. typical 30-50ms)
✅ Stronger peak power handling (170% overload)

Deye’s PCS + BOS-B system is a compelling all-in-one solution for C&I solar+storage, offering top-tier efficiency, scalability, and reliability. As businesses seek to cut energy costs and ensure uptime, this technology could become a go-to choice for commercial electrification.
