Core Advantages

1. Power Density

At 43kg for 10,000W off‑grid output, the SUN-10KS48P3 delivers 232W per kilogram. This means lower shipping costs, simpler wall‑mounting without reinforced structures, and more units per shipping container directly reducing your project logistics and installation budget.

2. 250A Charge/Discharge

With 250A maximum charge/discharge current, the system supports battery banks of 300Ah and above. A 400Ah 48V battery bank charges from 20% to 80% in under 1.5 hours enabling full daily cycling even in regions with limited sunlight hours.

3. Up to 36A MPPT Input

Each MPPT channel supports up to 36A input current (2‑MPPT configuration), matching large‑format 210mm/182mm PV modules without current clipping. This reduces string count and cable losses by approximately 15‑20% compared to 18A MPPT designs.

4. 200% Overload for 15 Seconds

Off‑grid peak overload capacity reaches 200% of rated power for 15 seconds. This starts 7.5kW inductive loads compressors, pumps, elevators with startup currents 3‑5× higher than running current, eliminating nuisance tripping during motor startup.

5. 98% Peak Efficiency

At 98% peak efficiency and 97.5% European efficiency, the inverter loses only 2% of input energy. For a 10kW system operating 1,500 full‑load hours annually, this efficiency level saves approximately 300‑500 kWh per year compared to 95% efficient inverters translating into quantifiable ROI improvement.

6. IP66 All‑Weather Enclosure

Rated IP66, the unit is fully dust‑tight and protected against powerful water jets. External wall, carport, or rooftop installation preserves indoor floor space  eliminating the need for dedicated equipment rooms. Operating temperature range spans ‑25°C to +60°C, covering 95% of the world's inhabited regions without climate‑controlled enclosures.

7. Three-Phase Unbalanced Output

The 3 Phase 10KW Hybrid Solar Inverter supports unbalanced three‑phase output, allowing each phase to independently supply its connected single‑phase loads without derating the entire system. In real‑world residential and commercial installations where phase loading is rarely perfectly balanced, this feature delivers 15‑30% more usable capacity compared to inverters that require balanced loads.

Safety and Intelligent Features

1. Full Suite of Protection Functions

The SUN-10KS48P3 incorporates comprehensive protection features, including PV reverse polarity protection, insulation resistance detection, residual current monitoring, over-current protection, short-circuit protection, over-voltage protection, anti-islanding protection, surge protection, and an integrated DC switch. These multiple layers of protection ensure safe operation under all conditions, safeguarding both the inverter and connected equipment.

2. 48V Low-Voltage Safety Architecture

Operating at a 48V nominal battery voltage (configurable up to 60V), the system employs a safe low-voltage architecture that significantly reduces the risk of electrical hazards. The battery-side high-frequency isolation provides galvanic isolation between the battery and the AC side, further enhancing system safety. This low-voltage design is particularly important for installations where maintenance personnel may not have specialised high-voltage training.

3. Intelligent Battery Management Integration

With CAN and RS485 communication interfaces, the SUN-10KS48P3 integrates seamlessly with lithium battery BMS systems, enabling real-time battery monitoring, adaptive charging algorithms, and cell balancing. This intelligent integration extends battery life, optimises system performance, and provides users with comprehensive visibility into battery health and status.

4. Remote Monitoring & Smart Energy Management

The inverter supports remote monitoring via Wi-Fi or 4G connectivity, allowing users to track system performance, adjust operating parameters, and receive alerts from anywhere in the world. The system’s smart energy management capabilities—including time-of-use scheduling, peak shaving, and load management—enable users to optimise energy consumption and maximise savings.

5. Quiet Operation

With a noise level below 55dB, the SUN-10KS48P3 operates quietly despite its high power output, making it suitable for noise-sensitive environments such as residential areas, offices, and retail spaces.
