Solar generation, lithium battery capacity and household load on one screen – shown here with an illustrative example home.

Illustrative example – demo data, not a customer's live data. Evening Peak Battery Mode reduces grid draw during the 17:00–21:00 evening peak by running the home from the battery; Tshwane's domestic tariff does not change by time of day.
