MUST 10kVA Transformer Base Hybrid Inverter – Overview


What is it?

A MUST 10kVA transformer-based hybrid inverter is a high-capacity power conversion device designed to manage energy from multiple sources (solar, grid, generator, and batteries) for residential, commercial, or industrial use. The transformer-based design offers robust performance, especially for heavy-duty and inductive loads.




Key Features

  • Capacity: 10kVA (kilovolt-ampere), suitable for large homes, offices, or small industrial setups.

  • Hybrid Functionality: Can combine solar, grid, and generator power, and charge batteries.

  • Transformer-Based: Provides better surge handling, isolation, and reliability for sensitive or heavy loads.

  • Pure Sine Wave Output: Ensures compatibility with all types of appliances.

  • MPPT Solar Charge Controller: Maximizes solar energy harvest.

  • Battery Compatibility: Works with various battery types (lead-acid, lithium, etc.).

  • Automatic Transfer Switch: Seamless switching between power sources.

  • LCD Display: For monitoring system status and settings.

  • Remote Monitoring (optional): Some models support WiFi or GSM monitoring.


Typical Specifications

  • Rated Power: 10kVA / 8kW

  • Input Voltage: 230V AC (single-phase) or 400V AC (three-phase), depending on model

  • Solar Input: Up to 500V DC, MPPT range varies by model

  • Battery Voltage: Usually 48V DC (check model specifics)

  • Efficiency: 90–95% (inverter mode)

  • Surge Power: 2x rated power for a few seconds

  • Protection: Overload, short circuit, over/under voltage, over-temperature
