Common System Sizes
3kVA Systems
Ideal for small homes, providing essential backup for LED lights, TVs, Wi-Fi, and a standard fridge.
5kVA to 8kVA Systems
Powers medium to large households with extra appliances, deep freezers, and standard borehole pumps.
10kVA+ Systems
Engineered for massive estates, commercial operations, multi-geyser setups, and full off-grid independence.
Key Factors in Sizing
Daily Energy Consumption: Calculated in Watt-hours (Wh) based on your average ZESA bill or appliance usage.
Peak Sun Hours: Based on your geographical location (Harare averages 5-6 peak hours of production).
Appliance Load: Determining which devices will run simultaneously to calculate the inverter surge capacity.
Battery Storage Needs: Calculating the total backup hours required during evening load-shedding blocks.
