Load-shedding has made backup power a necessity for South African homes. But how big a system do you actually need? This guide walks you through the basics.
1. List your essential loads
Start with what you truly need during an outage: lights, WiFi router, TV, fridge and phone chargers. Add up their wattage to estimate your running load.
2. Decide on backup duration
A typical Stage 4 slot lasts around 2.5 hours. A 5kWh lithium battery like the Pylontech US5000 comfortably covers essential loads through most slots.
3. Match your inverter
A 5kW hybrid inverter such as the Sunsynk 5kW ECCO suits most homes, while larger households may prefer 8kW. Browse our inverters to compare.
