Project Brief

The core of this Romanian installation lies in its premium high-voltage architecture, designed for minimal conversion losses and long-term reliability. The technical breakdown includes:

Inverter System: A Deye 80kW high-voltage hybrid inverter, serving as the intelligent brain of the system to manage solar generation, battery storage, and grid synchronization.

Battery Infrastructure: Dawnice 225kWh DC Outdoor Storage Cabinet (BS09-225-D).

Battery Chemistry: Ultra-safe Lithium Iron Phosphate (LiFePO4) technology.

System Voltage and Capacity: A 716.8V high-voltage configuration powered by premium 314Ah large-capacity cells.

Energy Delivery: A total nominal capacity of 225.07kWh, yielding 202.56kWh of active, usable energy at a standard 90% Depth of Discharge (DOD).

Environmental Resilience: IP54-rated weatherproofing coupled with a C3 anti-corrosion grade (with a C5 option available) to withstand harsh Romanian winters and hot summers.

The system was commissioned for a prominent industrial facility in Romania experiencing rapid production scaling. The facility expansion brought several critical energy challenges to light:

1. Volatile Energy Infrastructure: The local regional grid experienced occasional voltage drops and power quality issues, which threatened to cause costly downtime for sensitive automated machinery.

2. Underutilized Solar Assets: While the facility featured a large rooftop solar array, a significant portion of the clean energy generated during non-production weekend hours was being wasted or fed back to the grid at unfavorable rates.

3. Corporate Carbon Mandates: In alignment with EU-wide green industrial standards, the company needed a clear pathway to reduce its carbon footprint and prove its commitment to sustainable manufacturing.

Project Highlights

• Multi-Tiered Safety and Active Fire Suppression For an indoor or outdoor industrial deployment, safety overrides all other metrics. The Dawnice 225kWh storage cabinet is engineered with a comprehensive, multi-level battery warning and protection algorithm that monitors cell health in real-time. Furthermore, the enclosure is equipped with an integrated automatic fire alarm and an automatic internal fire extinguishing system, ensuring instant containment of any thermal risk.

• Heavy-Duty Lifecycle and Rapid ROI The economic value of the system is backed by exceptional longevity data. Operating under standard conditions (25 degrees Celsius, 0.5C/0.5C charge/discharge at 90% DOD), the internal battery cells boast a cycle life of 8000 cycles or more (up to 70% End of Life). This translates to an impressive cumulative discharge energy throughput of 361.4MWh over the system’s lifespan. Protected by a 5+5 years warranty period, the facility is guaranteed over a decade of lowered utility costs and stable asset performance.

• Thermal Efficiency and Seamless EMS Integration Romania experiences a demanding climate with a wide temperature spectrum. The Dawnice cabinet is built to operate flawlessly from -30 to 55 degrees Celsius thanks to its built-in intelligent air-cooling climate control system, which maintains optimal internal temperatures. Using integrated CAN and RS485 communication protocols, the battery system interfaces directly with the central Energy Management System (EMS), giving the facility’s operators complete transparency over their energy workflows.
