Deye SUN-10K-SG04LP3-AU

The “Set and Forget” Three-Phase Powerhouse

The Deye 10kW three-phase hybrid inverter is engineered for users who want a high-performance system without constant intervention. In many hybrid setups, owners end up micromanaging charge windows, SOC limits, and export behaviour. The Deye eliminates that friction.

This is a true all-in-one hybrid platform that seamlessly manages:

• Grid interaction
• Battery storage
• Backup power
• Solar optimisation

—all within a single unit.

Intelligent Energy Management with Deye Copilot

At the core is Deye’s Copilot system.

Rather than relying purely on fixed schedules, it dynamically optimises:

• Load vs generation
• Battery charge/discharge timing
• Grid import/export behaviour

It factors in:

• Household consumption patterns
• Time-of-use pricing
• Solar generation trends

The result is a system that maximises self-consumption and ROI without constant user input.

Why It Outperforms Complex Modular Systems

Compared to modular ecosystems like Victron Energy:

• Far faster install time
• Lower system cost
• Integrated hybrid control (no external GX / Cerbo dependency)
• Cleaner commissioning process

You still retain:

• Full battery control
• Generator integration
• AC coupling capability

But without the overhead of multi-device configuration.

Engineered for Reliability

Proven Platform
Deye hybrids are widely deployed globally with strong reliability in harsh conditions.

Massive PV Oversizing
Supports up to 20,000W PV input, allowing aggressive oversizing to maintain battery charge in poor weather.

Dedicated Generator Port
Built-in generator input ensures full off-grid resilience during extended low-solar periods.

48V Low Voltage Architecture

• Safer installation environment
• Broad compatibility with lithium batteries
• Ideal for residential and light commercial systems

Technical Architecture & System Dynamics

The inverter uses a high-efficiency non-isolated DC–AC topology (~97.6%), combined with safe low-voltage battery operation.

This gives you:

• High conversion efficiency
• Reduced thermal losses
• Stable hybrid switching behaviour

Advanced Three-Phase Load Handling

A major differentiator:

100% Unbalanced Load Support

• Full support for uneven phase loads
• Up to 50% of rated power (~5kW) can be delivered on a single phase

This is critical in Australia where:

• Air conditioners
• EV chargers
• Workshop equipment

are often single-phase loads on a 3-phase supply.

DC & AC Coupling Flexibility

The system supports both:

DC Coupling (New Installs)

• 2 MPPT trackers
• Wide voltage range (200–650V)
• Up to 800V max input

AC Coupling (Retrofits)

• Add battery storage to existing solar
• Retain current grid-tied inverter
• Upgrade system intelligence without replacing PV

Scalable for Larger Systems

Parallel capability:

• Up to 16 units in parallel
• Supports on-grid and off-grid microgrid operation
• Communication via CAN / RS485

This enables:

• Commercial installs
• Large residential estates
• Off-grid communities
