- A Modular Energy Storage Platform
The series combines separate battery storage, power conversion and source-switching equipment in a configurable architecture. This allows project designers to select the components required for grid-connected, off-grid and hybrid microgrid applications.
The solution supports peak shaving, energy arbitrage, renewable energy smoothing, backup power, frequency regulation and participation in virtual power plant programs.
- 4.34 MWh Liquid-Cooled Battery Container
The WS-L4300-BC-3 provides 4,340 kWh of nominal energy using 314 Ah LiFePO4 cells. Its 18 battery racks operate at a nominal DC voltage of 768 V, with a specified operating range of 648–876 V.
Liquid cooling supports battery thermal management, while aerosol and water fire-suppression systems provide layered protection. The IP55-rated enclosure is supplied in a 20-foot container format for transport and site installation.
- Modular 1,125 kW Power Conversion
The WS-PCS1125-2-A integrates nine 125 kW PCS modules to provide 1,125 kW of rated AC power. Its modular construction supports system availability and simplifies power conversion management at the cluster level.
The PCS operates with a battery input voltage range of 630–1,000 V DC and provides a rated 400 V AC output at 50 Hz. Its power factor is adjustable from −1 to +1.
- Grid, Load and Generator Management
The WS-TS1000-2-A provides dedicated connections for the grid, load and generator. Each circuit supports 1,000 kW of rated bidirectional active power at 220/380 V or 230/400 V three-phase voltage.
A specified switching time of no more than 20 ms supports transitions between available power sources in compatible backup and microgrid configurations.
- AC- or DC-Coupled Solar Integration
The system can be configured for AC-coupled PV integration using compatible solar inverters. For DC-coupled projects, optional MS-MPPT200-2 modules can connect PV generation to the battery DC bus.
Each MS-MPPT200-2 provides eight MPP trackers, supports up to 200 kW of PV access capacity and supplies up to 160 kW of PV input power. Nine modules can provide up to 1,800 kW of total PV access capacity in the illustrated configuration.
- Intelligent Energy Management
The optional MS-EMS supports peak-valley energy arbitrage, export limitation, transformer overload protection, load tracking, demand control, backup power, phase control and SOC balancing.
Advanced functions include load forecasting, production planning, electricity-price planning and economic operation optimization. Deye Cloud connectivity supports remote monitoring and system management.
- Built for Demanding Environments
The battery container operates from −30°C to 55°C and carries an IP55 enclosure rating. The PCS and switching unit use IP54 enclosures and support optional C5 corrosion protection.
The system architecture includes multiple layers of fire and electrical protection, AC leakage detection, DC insulation monitoring and high-voltage interlocking.
