💡 Inverter Recommendations & Tips

🔧 Inverter Types

  • Modified Sine Wave:
    Budget option, not for sensitive electronics
  • Pure Sine Wave:
    Recommended for all electronics
  • Hybrid Inverter:
    Grid-tie + battery backup

⚡ Common Sizes

  • 0.5-1 kVA:
    Small RV, emergency backup
  • 2-3 kVA:
    Average home, office
  • 5-10 kVA:
    Large home, small business

📊 Critical Factors

  • Surge capacity: Motors need 3-5× running wattage
  • Efficiency: High-quality inverters are 90-95% efficient
  • Voltage drop: Higher voltage (48V) reduces cable size/cost
  • Temperature: Derate by 10-20% in hot environments
