How to Size Your Inverter

Step 1: Calculate Peak Load

Add up the wattage of everything you want to run simultaneously. Common loads:

  • Fridge: 150-300W
  • Microwave: 1000-1500W
  • TV: 100-200W
  • Lights (LED): 10-20W each
  • Computer: 200-400W
  • Pool pump: 750-1500W

Step 2: Choose Inverter Size

Your inverter should handle your peak load plus 20-30% headroom:

  • Up to 2.5kW peak: 3kW inverter
  • Up to 4kW peak: 5kW inverter
  • Up to 6.5kW peak: 8kW inverter
  • Up to 8kW peak: 10kW inverter

Solar Inverter FAQs

Size your inverter based on your peak load (maximum power you'll use at once). 3kW: Essentials (lights, TV, fridge). 5kW: Average home (add microwave, some plugs). 8kW: Large home with multiple circuits. 10kW: Very large home or to run everything including pool pump. Check your main breaker size - a 60A supply can handle up to 13kW.
Hybrid inverters can work with grid power, solar panels, and batteries simultaneously. They're the most versatile and popular choice in SA. Off-grid inverters work without any grid connection - ideal for farms or remote locations. Grid-tie inverters feed excess solar to the grid but don't provide backup during load shedding.
2026 prices: 3kW hybrid: R12,000-25,000. 5kW hybrid: R18,000-35,000. 8kW hybrid: R28,000-55,000. 10kW hybrid: R45,000-85,000. Installation adds R5,000-15,000. Premium brands like Victron cost 30-50% more than Deye or Sunsynk.
Both are excellent choices for South African homes. Deye is typically 10-20% cheaper with similar features. Sunsynk has strong local support and is UK-designed. Both offer good warranties and work well with most battery brands. Choose based on installer recommendation and local support availability.
Yes, you can add a hybrid inverter to existing grid-tie systems. This allows you to add battery storage for load shedding backup. The new inverter needs to be compatible with your panel voltage and configuration. A qualified installer can assess your system and recommend the best solution.
Quality inverters last 10-15 years with proper installation and ventilation. Warranties typically cover 5-10 years. Inverters in hot, poorly ventilated spaces may fail sooner. Keep them clean, well-ventilated, and away from direct sunlight for maximum lifespan.
