How much does a solar battery cost in South Africa?

Battery-only prices vary with capacity, brand and configuration. Compare the exact usable capacity, warranty and compatibility, then add the cost of a compatible inverter, protection equipment, installation and compliance where those are part of the job.

Does a solar battery price include installation?

Not usually. Retail battery prices normally cover the battery unit only. An installed backup system may also need an inverter, electrical protection, cabling, labour, commissioning and certificate of compliance work.

What battery size do I need for load-shedding?

That depends on which appliances are backed up and for how long. Use a runtime estimate as a starting point, then have the inverter, battery and backup circuits designed together.

These are public battery-only prices checked on 29 August 2026. Stock, promotion and retailer pricing can change. They do not include an inverter, electrical work, installation or a certificate of compliance.

Solar lithium battery prices and lithium-ion solar battery prices only become useful when the quote states the exact model, capacity and installation scope. That is how you compare battery cost without treating two very different systems as the same purchase.

Avoid a false comparison

A battery price is not an installed backup price

Usable kWh

Two batteries with a similar label can offer different usable energy. Compare the warranty conditions and depth of discharge, not just the headline capacity.

Battery and inverter compatibility

The battery needs to communicate with the inverter and deliver enough power for the loads that will run together.

Installation scope

Ask whether the figure includes protection equipment, cabling, distribution-board work, commissioning and the compliance paperwork for your property.
