These units, commonly lithium-ion batteries, can set back consumers by a considerable margin ranging from ZAR 50,000 to ZAR 200,000 on average for a typical installation. This price variability often hinges upon the capacity and brand of the battery system chosen.
[pdf] The amount of electricity stored typically ranges from 5 to 20 kWh for residential systems, and larger commercial systems can hold significantly more, up to several megawatt-hours. Factors influencing storage capacity include battery type, cabinet design, and specific use cases.
[pdf] $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels. For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh.
