Best Solar Batteries in South Africa (2026): Brands, Sizes & Prices

The battery is what keeps your lights on during load shedding, and for many South Africans it is the most important part of a solar system. It is also one of the most expensive, so choosing the right one matters. Here is what to look for in 2026.

Lithium is the standard

Almost every new home installation uses lithium iron phosphate (LiFePO4) batteries rather than older lead-acid types. The reasons are clear:

• Longer lifespan, typically 6,000 cycles or more.
• A usable depth of discharge of 90 to 100 percent, versus around 50 percent for lead-acid.
• Compact, wall-mounted designs that are essentially maintenance-free.

For a full comparison see our guide to lithium vs lead-acid batteries.

Leading battery brands in South Africa

The local market has matured and there are several well-supported options, including proudly South African manufacturers. You can browse battery brands on our brands directory, but the names you will see most often include:

• Freedom Won and Hubble Lithium, both South African manufacturers with strong local support.
• Pylontech, Dyness, BYD and Shoto, widely stocked imported brands.

When comparing brands, prioritise warranty terms, the number of guaranteed cycles, local availability of support, and whether the battery carries a valid NRCS Letter of Authority.

How much battery capacity do you need?

Battery capacity is measured in kilowatt-hours (kWh). A simple way to think about it is how many hours of backup you want for which appliances:

• 5 kWh covers the essentials (lights, Wi-Fi, TV, fridge) through typical load shedding.
• 10 kWh comfortably runs essentials plus some heavier use across longer or back-to-back stages.
• 15 kWh and up suits larger homes that want to run most of the house overnight.

Our system size calculator helps you estimate the right capacity for your usage.

What does a solar battery cost?

As a rough 2026 guide, installed lithium storage works out to roughly R7,000 to R12,000 per kWh, so a 5 kWh battery often lands between R35,000 and R60,000 depending on brand and installation. Buying slightly more capacity than you need today is sensible because most systems can be expanded later.
