5kW Solar Inverters FAQs

Yes, for most homes. 5kW handles all essential loads during load shedding. You cannot run high-draw appliances like stoves, ovens, or geysers simultaneously, but it covers 80% of typical household needs. For larger homes, consider 8kW.
Typically 8-12 panels (400-550W each) for a 5kW inverter. The exact number depends on panel wattage and your energy needs. Most 5kW systems use 10 x 550W panels (5.5kWp) for optimal balance.
Add up the wattage of appliances you want to run simultaneously. For essentials (lights, TV, WiFi, fridge): 3kW. For essentials plus some appliances: 5kW. For whole house: 8-10kW. Most South African homes do well with 5kW hybrid inverters.
Hybrid inverters connect to both solar panels and the grid, automatically switching between power sources. Off-grid inverters work independently without grid connection. For load shedding backup with grid access, hybrid is the better choice.
