The ACE Solar WIT 28-55K represents a leap in commercial solar technology, engineered to meet the demanding energy needs of industrial facilities, large-scale commercial buildings, and utility-grade solar farms. As part of ACE Solar’s Growatt series, this inverter combines high power output (28–55 kW) with intelligent grid management, making it a cornerstone for businesses transitioning to renewable energy. Its modular design supports scalability, allowing seamless integration into existing infrastructure while future-proofing investments.
Power Output & Voltage Range:
Output Range: 28 kW to 55 kW, adjustable via software to match site-specific demands.
Grid Compatibility: Supports 3-phase AC output (480V/277V or 208V/120V), compliant with US grid standards (UL 1741 SA, IEEE 1547).
Efficiency: 98.5% peak efficiency, minimizing energy loss even at partial loads (e.g., 97.8% efficiency at 30% load).
Advanced Topology & Components:
Multi-Level MPPT: Dual independent MPPT trackers with 99.9% tracking accuracy, optimizing energy harvest from diverse PV arrays under shading or mismatched conditions.
Input Flexibility: DC voltage range of 600–1,000V, compatible with high-power PV modules (e.g., ACE Solar’s 695W Tier-1 panels).
Thermal Management: Integrated liquid cooling and IP65-rated enclosure ensure reliable operation in -25°C to 60°C environments.
Smart Grid Features:
Grid Services: Supports frequency regulation, voltage stabilization, and reactive power control (0.8 leading/lagging power factor).
Anti-Islanding Protection: Automatic shutdown during grid outages for safety.
Intelligent Energy Management:
Hybrid Readiness: Integrates with battery storage systems (e.g., ACE Solar’s STACK200A and NASA Series) for time-of-use optimization and backup power.
EV Charging Synergy: Native compatibility with ACE Solar’s C&I EVDS Charging Station, enabling solar-to-EV charging and reducing grid dependency.
Monitoring & Control:
Cloud-Based Platform: Real-time monitoring via ACE Solar’s proprietary app or web portal, featuring fault diagnostics, yield reports, and remote firmware updates.
API Integration: Compatible with SCADA and building management systems (e.g., Allen-Bradley industrial controllers).
Durability & Safety:
Robust Construction: Aluminum alloy chassis with corrosion-resistant coating, suitable for coastal or high-humidity installations.
Protection Mechanisms: Surge protection (IEC 61643), arc-fault detection, and ground-fault interruption.
Commercial Rooftops: Ideal for warehouses, shopping malls, and offices seeking to reduce operational costs.
Example: A 50 kW installation can offset 70% of energy costs for a mid-sized factory.
Solar Farms: Scalable for utility-scale projects with parallel operation of up to 12 units (660 kW total).
EV Charging Hubs: Powers fast-charging stations (150 kW+) using solar energy, as demonstrated by ACE Solar’s integrated solutions.
Plug-and-Play Design: Pre-configured cabling and wall/ground-mount options reduce installation time by 40%.
Predictive Maintenance: AI-driven alerts for component wear (e.g., capacitor degradation), extending lifespan to 15+ years.
Carbon Reduction: A 55 kW system can cut CO₂ emissions by 60 metric tons annually.
Financial Benefits: ROI within 4–5 years in high-sun regions, with 25-year performance warranty.
