DEYE 50KW 3-PHASE HYBRID INVERTER

The DEYE 50kW 3-Phase Hybrid Inverter represents industrial-grade solar technology designed for large-scale commercial, industrial, and utility applications where reliability, scalability, and high-power three-phase capacity are non-negotiable. Combining 50kW continuous output, 65kW solar MPPT capacity, 100A battery charging, and parallel scalability to 500kW (10 units), it delivers the performance and flexibility demanded by mission-critical energy infrastructure.

Industrial Three-Phase High-Voltage Architecture

Unlike residential inverters limited to single-phase or low-voltage three-phase, the DEYE 50kW operates at industrial high voltage (typically 480V AC), enabling direct connection to commercial three-phase distribution systems, industrial motor controllers, HVAC chillers, manufacturing equipment, and large-scale refrigeration without step-up transformers or voltage conversion. The high-voltage architecture reduces conductor cross-sections, minimizes distribution losses, and integrates seamlessly with existing industrial electrical infrastructure.

65kW Oversized Solar Input Capacity

With 65kW MPPT capacity — 30% higher than the rated 50kW output — the inverter captures maximum solar energy even during suboptimal conditions. Dual MPPT trackers enable independent optimization of two separate solar arrays with different orientations, tilt angles, or shading profiles, critical for large rooftop installations or ground-mount arrays spanning multiple orientations.

High-Voltage Battery Integration

Supporting high-voltage battery systems (typically 600–800V DC), the inverter reduces battery cabling requirements and current-related losses compared to low-voltage architectures. The 100A charging current enables rapid replenishment of large commercial battery banks (200–500kWh+) for applications like peak shaving, demand charge reduction, and extended backup power.

Parallel Scalability to 500kW

Up to 10 DEYE 50kW inverters can be paralleled to create a 500kW three-phase system — scaling from a small commercial building to a mid-size industrial facility without equipment replacement. Parallel operation provides both capacity expansion and N+1 redundancy, ensuring continuous operation even during maintenance or component failure.

Advanced Grid Services & Hybrid Intelligence

Operating in grid-tied, off-grid, or hybrid modes, the inverter provides sophisticated energy management: peak shaving (reducing demand charges by discharging batteries during peak periods), load shifting (storing cheap off-peak energy for peak use), frequency regulation (supporting grid stability), and seamless backup power during outages. SCADA integration enables utility-scale monitoring and control.

Industrial-Grade Build & Reliability

IP65-rated enclosure withstands harsh industrial environments. Advanced thermal management (forced air or liquid cooling) maintains optimal operating temperature under sustained high loads. Integrated arc fault detection, anti-islanding protection, and ground fault monitoring ensure safe operation in all conditions.

Remote Monitoring & Diagnostics

Wi-Fi, LAN, and RS485 interfaces enable comprehensive remote monitoring via mobile app, web portal, or SCADA systems. Real-time visibility into solar production, battery state, grid interaction, and system health enables proactive maintenance and optimized performance.

A proven, scalable three-phase hybrid inverter for commercial and industrial solar installations demanding uncompromising performance, reliability, and future expansion capacity.
