30kW Three-Phase Off-Grid Inverter with Dual MPPT and 250-850V Battery

Industrial-Grade Power Conversion for Demanding Environments

This 30kW three-phase hybrid inverter represents a robust energy solution engineered for remote and mission-critical applications where grid reliability is unavailable. By integrating solar power conversion, battery storage, and generator support into a single unified system, it eliminates the need for separate components while delivering exceptional operational flexibility.

Key Features & Benefits

1. High-Efficiency Energy Conversion

30kW continuous output (33kVA peak)

• Capable of powering industrial machinery, telecom base stations, and off-grid communities with stable three-phase power. The 10% overload capacity (33kVA) handles motor startups and surge loads without voltage fluctuations.

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

• Two independent maximum power point trackers allow connection of solar arrays with different orientations or panel types (e.g., east-west roofs). The 250-850V operating range accommodates both standard 60-cell and high-voltage 72-cell modules.

<3% total harmonic distortion (THD)

• Produces utility-grade power quality that safely operates sensitive medical equipment, laboratory instruments, and variable-frequency drives. Active harmonic filtering technology prevents damage to connected devices.

2. Advanced Battery Management

250-850V battery voltage compatibility

• Directly supports modern high-voltage lithium systems (300-800V) without additional converters, reducing energy losses by 2% compared to low-voltage architectures. Also compatible with lead-acid batteries through adjustable charging profiles.

36kW maximum charging power

• Rapidly replenishes battery banks during peak solar production, enabling 80% state-of-charge recovery in under 2 hours for 200kWh systems. Adaptive algorithms prevent overcharging while maximizing cycle life.

CAN/RS485 BMS communication

• Real-time monitoring of battery temperature, voltage, and state-of-charge via industry-standard protocols. Compatible with major lithium battery manufacturers' management systems.

3. Military-Grade Reliability

-30°C to 55°C operational range

• Arctic-grade components ensure cold-start capability at -25°C, while desert-proof cooling maintains full output up to 45°C (derating to 80% at 55°C). Ideal for mining sites in Siberia or solar farms in the Middle East.

IP20-rated enclosure

• Protects against dust ingress and accidental contact, though requires indoor or sheltered installation. Stainless steel fasteners prevent corrosion in coastal environments.

110% continuous overload capacity

• Sustains 33kW output indefinitely to handle prolonged heavy loads, with 120% (36kW) burst capacity for 1-minute motor starts. Reinforced IGBT modules withstand 100,000+ surge cycles.

4. Intelligent Grid Integration

Automatic generator synchronization

• Seamlessly integrates with 30-50kW diesel generators, optimizing fuel efficiency by maintaining 40-80% load rates. Reduces fuel consumption by 35% compared to conventional setups.

Parallel operation support

• Up to 6 units can be synchronized (180kW total) via CAN bus communication. Master-slave configuration ensures equal load sharing with <1% power imbalance.

TCP/IP remote monitoring

• Web-based interface provides real-time diagnostics, historical performance data, and firmware updates. Compatible with SCADA systems via Modbus TCP.

Technical Specifications

Certifications & Compliance

• IEC 62109-1: Certified protection against electrical hazards including arc faults and ground faults.

• VDE-AR-N 4105: Complies with German grid standards for voltage/frequency regulation.

• EN 61000-6-4: Meets industrial electromagnetic compatibility requirements.

Implementation Guidelines

1. Installation

   • Foundation must support 800kg dynamic loads

   • Minimum 500mm clearance for airflow

   • 95mm² copper cables required for battery connections

2. Maintenance

   • Annual thermal imaging of power terminals

   • Quarterly air filter replacement in dusty environments

3. Typical ROI

   • 3-5 years for mining operations replacing diesel

   • 4-6 years for telecom tower power
