Many households either already have an electric vehicle (EV) or plan to buy one in the next few years. An EV can be one of the biggest single loads in a home. If you charge the EV only from the grid at night, your bills can rise sharply.
A solar battery lets you store daytime solar energy and use that energy to charge your EV later. You may not cover every kilometre with solar power, but you can still shift a large part of your EV charging away from expensive grid power.
A solar battery can provide a solid base for overnight EV charging, especially when you also use smart EV chargers that can adjust charge rates and times. You may choose to charge the EV more slowly over longer periods to match your stored energy rather than charging at maximum power all at once.
The same idea applies to other smart home loads, such as heat pumps, smart water heaters, and controlled pool pumps. When your home has a good-sized solar battery, you can run these loads in a way that fits your own energy supply rather than only the grid’s schedule.
