Three-phase hybrid inverter — Deye SUN-50K-SG01HP3-EU-BM4
The Deye SUN-50K-SG01HP3-EU-BM4 is a three-phase hybrid inverter designed for commercial and large residential PV plus storage installations. Combining a 50 kW nominal inverter with high DC input capacity, multiple MPPTs and robust protections, this model targets high-power rooftop, commercial and energy storage system applications where efficiency, reliability and HV battery compatibility are required.
Applications and use cases
This three-phase hybrid inverter is engineered for commercial rooftops, small industrial sites and larger multi-phase residential systems that require PV generation tied with battery storage. Its hybrid architecture enables grid-tied PV production, battery charging/discharging and backup functionality in one device, making it suitable for self-consumption optimization, peak shaving and microgrid support.
- Three-phase design for commercial and industrial power systems
- Hybrid inverter functionality for PV + battery energy storage systems
- On-grid export control, self-consumption and backup-ready operation
- Scalable for multi-unit installations and commercial rooftops
Key electrical and performance parameters
The SUN-50K delivers a nominal AC output of 50 kW with short-term support up to higher AC power, while accepting a substantial PV array input. Multiple MPPT inputs and high DC voltage capability ensure flexible PV string layouts and strong generation harvesting across varied roof orientations.
- Nominal inverter power: 50 kW with maximum AC power capability around the inverter peak rating
- Maximum DC input power: 65 kW, supporting large PV arrays
- Max. DC voltage: up to 1000 V for high-voltage PV string compatibility
- MPPT configuration: 4 independent MPPTs, each handling strong string current (36 A per MPPT indicated as 36+36+36+36)
- DC inputs: 8 separate inputs, typically configured as two strings per MPPT for layout flexibility
- AC nominal voltages supported: 220/380 V and 230/400 V at 50/60 Hz with adjustable power factor (0.8 leading to 0.8 lagging)
- High conversion performance with maximum efficiency up to 97.6% and Euro efficiency around 97%
Battery and backup capabilities
As a hybrid inverter, this model integrates PV conversion with battery management features and is suitable for high-voltage battery systems. It incorporates protections and monitoring required for safe charging and discharging and can be deployed where energy storage is used for load shifting, resilience or islanding scenarios.
- Hybrid inverter topology for direct connection to battery storage systems (supports HV battery architectures in typical configurations)
- Built-in battery protection features including battery over-current protection
- Designed for charge/discharge coordination with PV production and grid interaction
- Supports backup and off-grid transition modes when paired with compatible battery systems and controls
Operating conditions and reliability
The SUN-50K is built for demanding environmental conditions and continuous commercial operation. A wide operating temperature range, IP65 enclosure rating and extensive electrical protections protect the inverter and attached PV and battery systems from common field hazards.
- Operating temperature range: -40 °C to +60 °C suitable for harsh climates
- Protection class: IP65 for outdoor or semi-outdoor installations without special shelter
- Comprehensive protection suite: PV input lightning protection, anti-islanding, reverse polarity protection, insulation resistor detection, residual current monitoring, output over-current/short-circuit/over-voltage protections and over-voltage category ratings
- Local status interface: LCD + LED for onsite monitoring and diagnostics
- Typical product warranty period: 5 years (manufacturer-specified)
Mechanical design and installation
The inverter's form factor balances serviceability and footprint for commercial installs. Its enclosure and mounting dimensions reflect a compact, transportable unit that can be integrated into plant rooms or mounted in protected outdoor locations while providing accessible DC/AC and communication connections.
- Dimensions: approximately 894 mm (H) × 527 mm (W) × 294 mm (D)
- Weight: around 75 kg, manageable for typical commercial installation crews
- Rugged enclosure design with IP65 rating for dust and water ingress protection
- Multiple DC inputs and AC terminals to simplify stringing and multi-array connections
