3.5 kva 24v Cee Power Hybrid Solar Inverter

A 3.5kVA 24V Hybrid Cee Power Solar Inverter is a powerful and versatile unit designed for home or small office use, providing backup power from solar, battery, and grid sources. However, running 3.5kVA on a 24V system draws high current, so let’s look at key specs, pros, and best practices.

⚙️ Key Specifications

⚡ What You Can Power (~2800W)

• All house lighting (LED)

• 4–6 fans

• 1 medium refrigerator or freezer

• 1 TV + decoder

• Laptops, routers, small appliances

• Possibly a washing machine or water pump (if load is staggered)

⚠️ Avoid running everything at once; prioritize essential loads.

🔋 Battery Recommendations

System Voltage: 24V

• Current drawn at full load: 2800W ÷ 24V ≈ 117 Amps — high!

• Battery setup:

  • 2 × 12V, 200Ah to 300Ah deep-cycle batteries minimum

  • Prefer tubular, GEL, AGM, or LiFePO₄ batteries

• Add parallel strings for longer backup (e.g., 2S2P = 4 batteries, 24V 400Ah)

🔆 Solar Panel Recommendations

• Typical solar input range (depends on MPPT or PWM):

  • Use MPPT if possible for better efficiency

• Suggested panel size: 1000W – 1800W

  • e.g., 4 to 6 × 300W panels (in 2S2P or 3S2P config)

✅ Features (Standard with Cee Power Hybrid Inverters)

• Built-in solar charge controller (MPPT preferred)

• Auto switch between solar, battery, and grid

• LCD display for real-time status

• Overload, short circuit, low/high voltage protection

• Generator-compatible

• Prioritization settings (Solar first, then battery, then grid, etc.)

🔋⚠️ Important Note on 24V at 3.5kVA:

• 3.5kVA at 24V is pushing the limits of a low-voltage system.

• Consider moving to a 48V system for better efficiency and safety if your power demand grows.
