Deye SUN-20K-SG05LP3-EU-SM2 20kW Three-Phase Hybrid Solar Inverter
Scale your commercial backup power architecture with the Deye SUN-20K-SG05LP3-EU-SM2. This high-capacity 20kW three-phase hybrid solar inverter is engineered specifically to manage demanding electrical loads across industrial sites, large residential estates, and commercial facilities in Myanmar during prolonged grid dropouts. Featuring an advanced low-voltage 48V battery isolation design, this inverter delivers elite system safety while supporting large-scale energy storage configurations.
The Deye SUN-20K stand out with its unique ability to manage 100% unbalanced phase outputs (up to 50% rated power per single phase). This feature protects sensitive equipment across erratic power supplies in Yangon, Mandalay, and rural industrial zones alike.
Key Features & Engineering Highlights
- Unrivaled Per-Phase Flexibility: Supports 100% unbalanced three-phase output configurations. It dynamically routes up to 50% of the total rated power into a single phase to handle uneven commercial facility loads easily.
- Massive 350A Charge & Discharge Current: Equipped with an ultra-powerful 350A battery charging path that ensures rapid power collection from solar or generator inputs to top off battery reserves quickly.
- 48V Low-Voltage Storage Architecture: Engineered with full transformer isolation for enhanced equipment safety. This configuration utilizes cost-effective 48V low-voltage lithium or lead-acid battery banks rather than dangerous high-voltage lines.
- Diesel Generator Integration & Storage: Built-in compatibility allows direct integration with industrial diesel generators. It automatically paths excess generator output directly into your backup battery storage.
- Scalable Parallel Functionality: Supports parallel scaling for up to 10 separate units across both on-grid and off-grid operational models, scaling system capacity up to a massive 200kW.
- AC Coupling Capabilities: Effortlessly integrates directly into your pre-existing grid-tied commercial solar setups without requiring any infrastructure teardowns.
- IP65 Weatherproof & Ruggedized Chassis: Fully rated at IP65 dust and fluid ingress protection, ensuring reliable long-term performance in hot, high-humidity climates.
