It represents one of the most powerful models in Deye’s SG05LP3 hybrid series, offering exceptional energy management, high scalability, and intelligent integration of solar, battery, grid, and generator power sources. It is built to deliver stable, efficient, and uninterrupted electricity supply even in demanding power environments.

This inverter is engineered for both on-grid and off-grid operation, making it suitable for hybrid solar systems where energy independence and backup reliability are critical. Its three-phase architecture ensures balanced power distribution across large loads, making it ideal for applications with heavy machinery, multiple buildings, or high-consumption electrical systems.

⚡ High-Power 20kW Three-Phase Output

The SUN-20K-SG05LP3-EU-SM2 delivers strong and stable three-phase power suitable for industrial-grade applications:

• Rated AC Output Power: 20,000W
• Maximum AC Output Power: 22,000W
• Three-Phase Output (400V class systems)
• Pure sine wave output for sensitive equipment
• High surge capability for motor starting loads
• 100% unbalanced load handling across phases

This means each phase can independently support loads, making it especially useful where loads are not evenly distributed.

It can power:

• Industrial machines and workshop equipment
• Large air conditioning systems
• Water pumping systems
• Hotels and commercial refrigeration
• Office complexes and data systems
• CCTV and security infrastructure
• Agricultural processing equipment

☀️ Advanced Dual MPPT Solar Technology

The inverter uses 2 independent MPPT trackers, allowing efficient solar harvesting from multiple panel arrays with different orientations or shading conditions.

Key solar input specs include:

• Maximum PV Input Power: up to 30kW
• Maximum DC Voltage: 800V
• MPPT Voltage Range: 160V – 650V
• Multiple PV string support per MPPT
• High DC input flexibility for large solar arrays

This design ensures maximum energy yield even when solar panels are installed on different roof sections or exposed to varying sunlight conditions.

🔋 Powerful Battery Storage Integration

The SUN-20K-SG05LP3-EU-SM2 is designed for 48V low-voltage battery systems, supporting both lithium and lead-acid batteries.

Battery capabilities include:

• Battery Voltage Range: 40V – 60V
• Maximum Charging Current: 350A
• Maximum Discharging Current: 350A
• Parallel battery support for large storage banks
• Intelligent BMS communication (CAN / RS485)

The extremely high current rating allows fast charging and strong discharge support, making it suitable for large-scale backup systems or energy shifting applications.

🧠 Intelligent Energy Management System

This inverter is not just a power converter—it is a smart energy controller.

It supports:

• Self-consumption optimization
• Peak shaving (reducing expensive grid usage)
• Time-of-use scheduling (up to 6 periods daily)
• Load prioritization
• Export control and energy balancing
• Smart battery charging strategies

These features help reduce electricity costs while maximizing the use of solar energy and stored battery power.

🔌 Hybrid Operation (Solar + Grid + Battery + Generator)

The SUN-20K-SG05LP3-EU-SM2 can operate in multiple modes:

• Grid-tied mode
• Off-grid mode
• Hybrid solar + battery mode
• Generator-assisted backup mode

It automatically switches between energy sources to ensure continuous power supply, making it highly reliable for areas with unstable grid electricity.

It can also store energy from a diesel generator, adding flexibility for backup power strategies in critical installations.
