Solar + EV charging

How to take advantage of solar-smart charging

Solar-smart charging helps you use more of your own solar generation and less grid power by timing and controlling your EV charging sessions.

Start with your solar production window

Identify when your system typically produces surplus energy. In many homes, this is late morning to mid-afternoon. Scheduling charging into this window improves self-consumption and can reduce import costs.

Example: if your panels peak between 10am and 2pm, scheduling EV charging in that window can reduce daytime grid imports during weekdays.

Use charger controls and smart modes

Look for chargers that support solar diversion, dynamic current adjustment, and timer schedules. These features can taper charging up or down depending on available solar, so you avoid drawing more from the grid than you intend.

Example: on partly cloudy days, dynamic current control can keep charging active at lower power instead of repeatedly switching on and off.

Practical setup tips

  • Set a minimum charging floor for days with variable weather.
  • Keep an overnight backup schedule for next-day driving certainty.
  • Review your retailer tariff so smart charging aligns with off-peak rates too.

Example: you might run solar-only charging on weekends, then switch to an off-peak overnight backup profile before workdays.
