3 Phase – High Voltage Battery Inverter

Next level performance and reliability with the Deye SUN-29.9K-SG01HP3-AU-BM3 Hybrid Inverter, engineered specifically for high-demand three-phase solar and battery systems. This model offers a massive 44.85kW of maximum PV input and delivers a powerful 29.9kW of rated AC output, making it ideal for commercial properties, large homes, and off-grid setups requiring true energy independence.

Designed to work with high-voltage battery systems, the SUN-29.9 seamlessly integrates solar generation, battery storage, and grid backup, offering smart energy management for maximum savings and security. Whether you’re feeding back into the grid or operating in off-grid mode, its three-phase output ensures smooth and balanced power delivery across demanding loads.

Certified by the Clean Energy Council (CEC) under AS4777.2:2020 standards, this inverter is fully approved for use in Australia, the SUN-29.9 offers outstanding performance, durability, and value.

Key Features:

• Massive PV Input: Up to 44,850W of solar panel capacity

• High-Power Three-Phase Output: 29,900W rated AC input/output

• High Voltage Battery Compatibility: Ideal for scalable energy storage

• CEC Certified: Approved for Australian installations (AZ 69026887)

• Flexible Hybrid Design: Solar, battery, and grid-ready

• Built-In Smart Features: Advanced monitoring, load shifting, off-grid and backup capabilities

• Long-Term Reliability: Certification valid until 2026 with proven Deye quality

Whether you’re building a robust residential system or a powerful small commercial setup, the Deye SUN-29.9 Hybrid Inverter delivers uncompromising performance, flexibility, and peace of mind.

Technical details :

• 100% unbalanced output；each phase
• AC couple to retrofifit existing solar system
• *Max. 10 pcs parallel for on-grid and off-grid operation; Support multiple batteries parallel
• Max. charging/discharging current of 100A
• High voltage battery, higher efficiency
• 6 time periods for battery charging/discharging
• Supports storing energy from generator

When it says: “100% unbalanced output; each phase“

it means:

• Each of the three phases (L1, L2, L3) can have a completely different load — they do not need to be balanced like in traditional three-phase inverters.

• You can draw 100% of the rated power from just one phase if needed, without causing problems.

In normal older three-phase systems, if the loads on each phase aren’t roughly equal, it can cause faults, inefficiencies, or inverter shutdowns.
But with the Deye hybrid (and a few other advanced hybrids), the inverter intelligently manages the phases individually — allowing highly unbalanced loads without any issue.

Example:
Suppose you have a SUN-29.9 (29.9kW output).
You could technically:

• Pull 29.9kW just from L1 (while L2 and L3 have almost no load), or

• Have 10kW on L1, 15kW on L2, and 4.9kW on L3,

• Or any other combination — the inverter automatically adapts.
