off-grid dc ac 480v 800kva 640kw pure sine wave | Deming Power

Aperçu du produit

The Onduleur solaire hybride DC AC 480V 800kVA 640kw onde sinusoïdale pure is a hybrid on/off-grid solar inverter engineered for industrial and commercial applications. With 800 kVA power capacity, this unit delivers reliable power conversion for demanding environments including solar plants, microgrids, energy storage systems, and off-grid industrial sites.

Principales spécifications

Operating Modes

• Grid-Tie Mode: Synchronizes with utility grid; feeds excess solar/wind power back to grid (where net metering permitted)
• Off-Grid Mode: Forms independent AC grid from solar/wind + batteries; automatically sheds non-critical loads when battery is low
• Hybrid Mode: Uses grid as backup when batteries are depleted; seamlessly switches between grid and battery
• Battery Charging Mode: MPPT solar charging + grid-assisted charging to maintain battery SoC

Application Scenarios

• Solar power plants with energy storage (PV + BESS)
• Off-grid industrial sites, telecom towers, remote communities
• Microgrids with mixed renewable + diesel backup
• Wind farms with hybrid storage
• EV charging infrastructure (V2G-ready)
• Manufacturing facilities with peak shaving
• Data centers requiring UPS-grade power continuity

Battery Compatibility

This unit supports a wide range of battery chemistries through configurable charge profiles:

• Lead-acid (flooded, AGM, gel) — bulk/float/equalize charging
• Lithium iron phosphate (LiFePO4) — CC/CV with cell balancing
• Lithium-ion (NMC) — BMS communication via CAN bus
• Flow batteries — configurable voltage/current limits
• Supercapacitor banks — for high-power pulse applications

Grid Connection Features

• Anti-islanding protection per IEEE 1547 / IEC 62116
• Reactive power and voltage support (Volt-VAR, Volt-Watt)
• Low-voltage ride-through (LVRT) capability
• Configurable power factor adjustment (0.8 – 1.0)
• Frequency response (50/60 Hz auto-detection)
• Anti-backfeed protection with optional grid relay

Protection Functions

Communication & Monitoring

• RS485 Modbus RTU (standard)
• CAN bus for BMS communication (Li-ion batteries)
• Ethernet (Modbus TCP) for SCADA integration
• Optional WiFi / 4G module for cloud monitoring
• Local LCD display + keypad for parameter setting
• PC-based configuration tool via USB or Ethernet
• Compatible with major solar monitoring platforms

Certifications

Frequently Asked Questions

Q: Can this inverter work with both solar and wind input?

A: Yes. Most units in this series support hybrid wind-solar DC input through MPPT channels. Wind input requires a charge controller for proper regulation.

Q: What is the typical delivery time?

A: Standard units: 7–15 days after order confirmation. Custom configurations: 30–60 days depending on specification complexity.

Q: Do you provide OEM/ODM services?

A: Yes. Jinan Deming Power is a real factory with 15+ years of OEM/ODM experience. We can manufacture under your brand with custom specifications.

Q: What warranty is provided?

A: 12 months standard warranty for the complete unit, 36 months for power components (IGBT/MOSFET modules), with extended warranty options available.
