Description

The SUN‑12K‑SG04LP3 from Deye is a three‑phase 12 kW hybrid inverter designed for residential to light commercial solar installations. Delivering efficient power management across solar PV, battery storage, and grid interactions, this inverter offers flexibility, continuity, and scalability. Its transformer‑isolation design ensures enhanced safety and reliability, paired with high charging capability and advanced energy management features.

 Key Features

 Flexible Hybrid Integration

• Seamlessly blends solar power, battery storage, and grid power with fast switchover (≤5 ms) for uninterrupted backup supply.

• Supports AC coupling, allowing retrofit with existing PV systems and generator integration.

Battery Compatibility & High Current Handling

• Designed for 48 V (40–60 V) systems, compatible with both lithium-ion and lead-acid batteries (including AGM and Gel).

• Supports max charging/discharging current of 240 A, allowing rapid energy storage and draw.

PV Input & MPPT Design

• Equipped with 2 independent MPPT trackers, each handling multiple strings (e.g. 2 + 1 setup).

• Accepts up to 15.6 kW DC, with MPPT range 200–650 V, startup at 160 V, and allows over-paneling within input limits.

• DC/AC ratio up to 1.3×, increasing PV yield without inverter oversizing.

 AC Output & Performance

• Rated AC power: 12 kW (max 13.2 kW apparent), with 100% unbalanced output (each phase up to 50% load).

• Peak (off‑grid): up to 2 × rated power for ~10 seconds.

• Efficiency: Max 97.6%, Euro efficiency ~97%, MPPT >99%.

• Adjustable power factor (0.8 leading to 0.8 lagging); THDi <3%, DC injection <0.5%.

Communication & Monitoring

• Interfaces: RS485, RS232, CAN, and optional Wi‑Fi/GPRS/LAN for remote monitoring and firmware updates via integrated platform.

• 6 programmable charging/discharging time blocks and support for time-of-use optimization

Protections & Safety

• Comprehensive safety: anti-islanding, surge protection (AC/DC Type II), reverse‑polarity, insulation monitoring, residual current detection, over-/under-voltage, short-circuit, overload protections.

• Features transformer isolation for added safety.

Design & Environmental Specs

• Ingress protection: IP65, suitable for indoor or outdoor mounting.

• Operating temperature: –40 °C to +60 °C (derates above 45 °C); altitude ≤ 2000 m.

• Size: approx 330–422 × 580–699 × 232–279 mm; weight 20–38 kg, depending on variant.Noise: ≤30–55 dB, with intelligent active cooling.

• Warranty: 5 years standard, expandable to 10 years depending on region/installer.

Scalability

• Supports parallel operation of up to 10 units (some references up to 16), enabling modular expansion for larger systems.
