Model: BS07-265-ES-G — Intelligent energy management for commercial deployments
The Dawnice BS07-265-ES-G is a commercial-class integrated energy solution combining a 125 kW inverter, 120 kW PV input capability and a 265.267 kWh LiFePO4 battery bank. Designed for resilient grid-tied and hybrid deployments, it provides automatic source transfer with genset coupling, advanced SOC/SOH management, and multi-layer safety systems including aerosol fire suppression and thermal runaway prevention.
Supports seamless PV/diesel/grid coupling, automatic source transfer (<20 ms), adaptive charge/discharge control and scheduling for peak shaving, backup and off-grid operation.
IP54-rated cabinet, modular layout for easier maintenance, C4 anti-corrosion grade (optional C5), and on-board HMI with CAN/RS485 communications for integration and fleet monitoring.
