Most modern home battery systems can be charged from the grid as well as from solar panels. This gives you flexibility and control over how and when your energy is stored.
Using low-rate electricity Many homeowners choose to charge their battery during off-peak or low-rate tariff periods, then use that stored energy later when electricity prices are higher. This is known as tariff shifting and can significantly reduce energy costs, even in winter when solar generation is lower.
Working alongside solar When solar is available, the battery will prioritise storing excess solar energy first. Grid charging simply adds another option, ensuring your battery is still useful year-round, not just on sunny days.
Helping the grid Charging batteries during low-demand periods and discharging during high-demand periods helps smooth demand on the electricity network. When many homes do this together, it reduces strain on the grid and supports overall system stability.
The takeaway Grid charging turns your battery into a flexible energy tool, not just a solar add-on. It gives you more control, better savings, and a system that works for you in every season.
