The short answer
There is no single price for a home battery in South Africa, because what you are really buying is a system. As a rough guide from the 2026 market, small storage batteries start around R9,000 to R10,000 for roughly 2.5 kWh (battery only, no inverter), while larger 5 kWh-class batteries commonly sit in the R28,000 to R38,000 band. All-in-one power stations that include an inverter and outlets span a wider range depending on capacity. These are indicative market figures gathered in mid-2026 and vary by retailer, promotion and configuration.
What actually drives the price
- Usable capacity (kWh): the biggest factor. More storage costs more, but the price per kWh usually improves as you scale up.
- Chemistry: lithium iron phosphate (LiFePO4) costs more upfront than older lead-acid, but lasts far longer, so the cost per usable cycle is lower. See LiFePO4 vs lead-acid.
- Inverter included or not: a bare battery still needs a compatible inverter, which is a separate purchase and install. An all-in-one battery builds the inverter in, so there is one product, one warranty and usually a faster install.
- Installation: wiring, mounting, a Certificate of Compliance and any grid paperwork add to the total, and vary by installer and site.
Battery-only vs all-in-one
A battery-only product looks cheaper on the shelf, but you then add an inverter and more install labour. An all-in-one unit folds the inverter, battery management and energy management into one stackable box. For many homes that lands at a better total cost and a simpler system, which is the approach the Sunpura range takes.
How to compare quotes fairly
- Compare usable kWh, not just headline kWh (depth of discharge matters).
- Check whether an inverter is included or quoted separately.
- Look at cycle life and warranty: a longer-lasting battery is cheaper over its life.
- Factor in rising tariffs, which shorten the payback. See Eskom tariffs and payback.
FAQ
Why do prices vary so much? Because “battery” can mean a 2.5 kWh wall unit, a 5 kWh stack, or an all-in-one with an inverter. Always compare like with like: usable kWh, inverter included or not, and install.
