Deye SUN-12K-SG05LP3-EU-SM2 12kW Three-Phase Hybrid Inverter
The Deye SUN-12K-SG05LP3-EU-SM2 is the flagship model in Deye's 3–12kW low-voltage three-phase hybrid inverter range, delivering exceptional performance for commercial, agricultural, industrial, and large residential applications. Designed to provide maximum energy independence, this advanced hybrid inverter intelligently manages solar generation, battery storage, grid power, and generator backup within a single integrated platform.
Engineered for demanding energy environments, the SUN-12K supports up to 24kW of PV access capacity, allowing businesses and homeowners to maximize solar production and significantly reduce reliance on utility power. Its advanced dual MPPT architecture continuously optimizes energy harvest from multiple solar arrays, making it ideal for installations with varying roof orientations or complex system layouts. With MPPT efficiencies exceeding 99%, the inverter ensures every available watt of solar energy is effectively utilized.
At the heart of the system is a robust 48V battery platform supporting both lithium-ion and lead-acid battery technologies. The inverter delivers an industry-leading 240A charge and discharge current, enabling rapid battery charging during peak solar production and reliable power delivery during periods of high demand. Intelligent battery management and communication with compatible lithium battery BMS systems help maximize battery lifespan and system performance.
The SUN-12K is designed to provide true energy resilience. During utility outages, the inverter seamlessly transitions to battery and solar power, maintaining uninterrupted operation of critical loads. Its ability to support 100% unbalanced output across all three phases provides exceptional flexibility for real-world commercial and industrial installations where loads are rarely perfectly balanced. The inverter can also store energy from diesel generators, making it ideal for remote sites and mission-critical applications.
Scalability is another major advantage of the SUN-12K. Up to 10 inverters can operate in parallel for both on-grid and off-grid applications, allowing businesses to expand system capacity as energy requirements grow. Multiple batteries can also be connected in parallel, creating a future-proof energy storage solution capable of supporting increasingly demanding loads.
With an IP65-rated enclosure, intelligent air cooling system, integrated protection features, remote monitoring capability via WiFi, RS485 and CAN communication, and a maximum efficiency of 97.6%, the SUN-12K delivers the reliability, flexibility, and performance required for modern energy storage projects. Whether deployed in manufacturing facilities, farms, office parks, retail centres, or large residential estates, this inverter provides a powerful foundation for long-term energy security and savings.
