Maximizing PV generation: By reducing the maximum PV feed-in power due to the charge at noon, more PV energy can be generated in total as no curtailment occurs. Reducing battery aging: Batteries age fast at high SOCs. A delayed charge reduces battery aging because the average SOC is kept lower than systems under the excess-charging strategy.
