Clear answer
Clear answer, explained.
A battery charges during low-cost periods—such as midday solar overproduction or overnight off-peak rates—and then discharges during expensive peak periods. This reduces grid purchases when electricity is most costly, lowering overall energy bills and improving the value of onsite solar generation.
Key points
What this means in practice.
- Stores energy during low-cost periods
- Discharges during high-cost or peak periods
- Reduces
- TOU energy charges
- Increases solar self-consumption
- Operates automatically through energy management software
When this applies
Best-fit environments.
- Businesses on
- TOU or demand-based tariffs
- Sites with daytime solar surplus
- Offices, retail, warehouses, and commercial facilities
