8kW Solar Inverters FAQs

8kW provides more headroom for running multiple appliances at the same time. If your home has higher power use, an 8kW inverter can prevent overloads during load shedding.
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.
