50kW Hybrid Inverter 55kVA Overload 120kW PV Input

Scalable Power Hub for Mid-Sized Energy Systems

This 50kW three-phase hybrid inverter is engineered for commercial and industrial applications requiring flexible energy management. Unlike compact 30kW units, it prioritizes modular expansion and high-density power conversion, making it ideal for businesses transitioning to solar-plus-storage solutions.

Key Features & Benefits

1. Enhanced Power Output & Efficiency

50kW continuous output (55kVA peak)

• Designed to power small manufacturing facilities, data centers, or agricultural processing plants with stable three-phase electricity. The 10% overload capacity (55kVA) supports heavy equipment startups without voltage drops.

Dual MPPT inputs (1,000V max PV voltage)

• Two independent trackers with 60-120kW PV input capacity allow for mixed array configurations (e.g., rooftop + ground-mounted solar). The 320-850V MPPT range optimizes performance with both 1500V and traditional 1000V strings.

<3% total harmonic distortion (THD)

• Delivers cleaner power than diesel generators, protecting sensitive CNC machines and medical imaging equipment. Active filtering adjusts dynamically to load changes.

2. Advanced Battery & Grid Integration

320-850V battery voltage range

• Directly pairs with high-voltage lithium systems (384V-800V), eliminating DC-DC converters and improving round-trip efficiency to 96.5%. Automatic chemistry detection simplifies commissioning.

60kW maximum charging power

• Charges 300kWh battery banks in 5 hours, ensuring overnight operation for cold storage facilities or 24/7 operations. Includes adaptive equalization charging for lead-acid batteries.

Generator load optimization

• Dynamically adjusts diesel gen-set output between 40-80% load for maximum fuel efficiency, reducing consumption by 30% compared to standalone generators.

3. Industrial Durability

-30°C to 55°C operational range

• Cold-start capability down to -25°C with heated components, while high-temperature derating begins at 45°C. Tested in Sahara desert and Siberian winter conditions.

IP20 protection with corrosion-resistant coating

• Zinc-nickel plated chassis resists salt spray corrosion, suitable for coastal installations. Removable air filters protect internal components in dusty environments.

120% transient overload (1 minute)

• Handles welding equipment or water pump surges without shutdowns. Reinforced DC bus capacitors rated for 100,000+ charge cycles.

4. Smart Energy Management

Plug-and-play parallel operation

• Connect up to 6 units (300kW total) via CAN bus with automatic master-slave negotiation. <2% power imbalance between units.

Time-of-use (TOU) optimization

• Programmable 6-period tariff settings to avoid peak demand charges. Integrates with energy management systems via Modbus TCP.

Black start capability

• Can reboot microgrids without external power source, critical for disaster recovery scenarios.

Technical Specifications

Certifications & Compliance

• IEC 62109-1: Full safety compliance including arc-fault detection

• AS/NZS 4777.2: Australian grid-connection certification

• EN 61000-6-4: Industrial EMC performance

Implementation Scenarios

1. Food Processing Plants

   • Maintains refrigeration during grid outages with seamless battery transition

   • Cuts energy costs by 60% through solar self-consumption

2. Cell Tower Power

   • 72-hour backup power with 200kWh battery

   • Remote firmware updates via 4G

3. Agricultural Cooperatives

   • Powers irrigation pumps during daytime peak solar production

   • Integrates with existing diesel generators

Maintenance & ROI

• Service Interval: 12 months or 8,000 operating hours

• Expected Lifespan: 10+ years with capacitor replacements at year 7

• ROI Period: 3-4 years for commercial users with demand charges
