Application:

Commercial and Industrial Solar-Storage Integration Projects

Energy Storage for Large-Scale Industrial Parks or Factories

Integrated solar-storage-charging stations

Areas with weak power grids or off-grid regions

Locations requiring high space utilization and large-capacity single-cabinet energy storage systems

The product supports multiple PV inputs (10 MPPT channels) and AC grid-connected or off-grid operation, and is compatible with a variety of operating modes and strategies.

Functions

Efficient use of space: With a footprint of just 1.4 m² and a capacity of 261 kWh per cabinet, it helps reduce space costs

Safe and reliable: Protection rating: IP55; liquid cooling + forced air cooling design; cell temperature difference ≤ 3°C; built-in aerosol fire suppression system (FSS)

Modular and scalable: Modular design with support for parallel connections, enabling flexible system expansion

System Simplification: A single cabinet covers the power requirements for most commercial and industrial applications (75–125 kW), reducing the number of inverters required in parallel

Deep Integration of Solar Power and Energy Storage: Integrated PV input (10 MPPT channels, maximum input power 150–250 kW) and AC output (75–125 kW); supports grid-connected and off-grid operation

Multiple operating modes: When paired with a hybrid inverter and a smart EMS, it supports multiple operating modes (self-consumption, peak shaving and valley filling, backup power, etc.)
