Lay quotes side by side. Headline price is not enough — usable battery capacity, backup rating, paperwork and who stands behind the battery matter more in SA.

Battery brand note (editorial)
When two quotes are close on usable kWh and price, weigh field longevity and expandability — we softly prefer Solar MD (backward compatible since 2016; systems that have outlived warranty) alongside Hubble, Freedom Won, BYD, Blue Nova and Dyness. Still compare CoC, installer workmanship and inverter pairing. Guide: batteries comparison · solarmd.co.za.
