  • Works with existing hardware – just connect your EV and solar inverter
  • Charge with free solar energy instead of grid power to reduce your energy bill
  • Match your vehicle charging to the times of your own solar production. This allows you to entirely self-consume the solar power you generate.

Frequently asked questions

  • Do I have to pay to use the app?

    Currently, the app and all essential services are free for users, and we have no plans to change that. As the app develops and we get your valuable feedback, we might add some paid premium features later.

    We are also collaborating with utility companies so they can offer our app services directly to you. That way, you will have a more centralized manner of dealing with all your electricity needs.

  • Which EVs and solar inverters do you support?

    Synergi supports all the most popular EV and solar inverter brands out there. You can see all supported EV models here and inverter models here.

  • What do I need to connect my EV and solar inverter to Synergi?

    You need your electric vehicle and its login credentials. The same goes for your inverter as we connect directly to the cloud software of your inverter.


  • Does the service collect information about me?

    The service collects only the necessary information, which is used to enable us to control your EV and inverter. We will never store any of your login information.

  • Do you have iPhone and Android apps?

    For now, Synergi offers a super flexible web app that works wonderfully on mobile and desktop. This enables us to develop the product faster based on your wishes (currently, we ship ~20 new weekly updates).

    We’ll start developing iPhone and Android apps at the end of the year. So, no worries – your wishes have been heard!

  • Is your application secure?

    Yes – your data privacy and safety are a top priority.
