Charge while it is cheap
AI used the 11:00 to 13:00 low-price window to build enough state of charge for the evening. Across five weekdays it accepted about $15.47 of cheaper energy to do it.
Spend it on the peak
That energy was held for the 17:00 to 20:00 peak. Peak imports fell to zero on 17 and 21 July, and from 31.3 kWh to 1.06 kWh on 20 July.
Know when to do nothing
On the weekend the load did not warrant it, so AI stayed with self-consumption. Nothing claimed, and nothing wasted on a charging cycle the site did not need.
Cross-check on a comparable solar day2 July, before AI Mode, ran on 39% solar and returned $13.75 in savings with the battery contributing 5%. On 15 July, with AI Mode and a similar 36% solar share, the same site returned $26.73 with the battery contributing 20%. This is not the baseline, but it points the same way: what changed was the timing, not the weather.
Basis: seven completed operating days, 15 to 21 July 2026, on a 30 kW / 63 kWh battery with 40 kWp of solar. Platform-recorded savings and the modelled comparison cover the same days. The comparison holds load and tariff constant, keeps a 10% minimum state of charge, and allows no grid charging in the self-consumption baseline. Site named on request with the customer's agreement.
