7.5kva 48v Integrity Transformer Hybrid Inverter

A 7.5kVA 48V Integrity Transformer Hybrid Inverter is a more powerful version of the 5kVA model, suitable for heavier household or small business loads. Let’s break down what this unit offers:

⚙️ Specification Overview:

✅ 7.5kVA Rating:

• Apparent Power: 7500VA.

• If the power factor (PF) is 0.8 (typical), real power output = 7500 × 0.8 = 6000W (6kW).

• Can support larger loads, such as:

  • Multiple air conditioners

  • Water pumps

  • Refrigerators, TVs, lights, and computers running simultaneously

✅ 48V Battery Bank:

• Still uses a 48V system, requiring:

  • Four 12V deep-cycle batteries in series

• For high-power output, you'll need batteries with sufficient amp-hour (Ah) capacity (e.g., 200Ah–400Ah each).

✅ Transformer-Based Design:

• Uses a built-in transformer:

  • Safer for sensitive and inductive loads.

  • Handles surge loads better (e.g., motor start-up).

  • More robust and durable, though bulkier than transformerless types.

✅ Hybrid Functionality:

• Can combine:

  • Solar input

  • Battery backup

  • Grid/mains input

• Supports automatic switching between power sources.

• May include MPPT solar charge controller (commonly 80A–120A).

🛠️ Key Features (typical):

• Pure sine wave output – clean electricity for electronics

• MPPT solar charge controller

• LCD/LED monitoring display

• Smart battery charging

• Protection: overload, short-circuit, high/low voltage, over-temp

• Optional grid-tie functionality

🔋 Battery and Solar Suggestions:

For optimal performance:

• Battery bank: 48V 400Ah (for ~19.2kWh of stored energy)

• Solar array: 5000W–7000W depending on usage
