Solar sold back earns pennies. Bought back at night it costs a fortune. SundialEV closes the gap automatically — shifting surplus into your EV directly.
Your rooftop solar is worth far more in your car than sold back to the grid. SundialEV automatically charges your EV from surplus solar instead of exporting it for pennies — set it once and forget it.
Under "Net billing" electric plans (like NEM 3.0), utilities pay you a few cents for the solar you export, then charge you full price for the same energy at night. Sundial closes that gap: when your panels make more than your home needs, it sends the surplus to your car instead of the grid, saving most users on their electricity bills.
• Set-and-forget — pick a charging floor and a battery reserve once; Sundial does the rest
• Works with every Tesla model — and with any EV brand via an OCPP smart wall charger, like the Wallbox Pulsar Plus
• Reads your production from Tesla, SolarEdge, or Enphase solar systems
• Coordinates with your Powerwall — you choose how full it gets before the car charges
• Tops up on cheap off-peak power on your schedule, and avoids peak-rate windows when solar isn't available
• Need range right now? One tap starts a full-speed charge — solar takes back over when it's done
• No new hardware — works with the solar, battery, car, and charger you already own
Provides an amazing amount of control for how and when you charge your vehicle. Supports charging rates and schedules across both solar and grid charging. Support is also very responsive to any needs or suggested features.
Great app
ChronoVII
Works to utilize my solar to charge my car! I have it set up so I don’t draw from the grid to charge my car (free fuel!) Very customizable and great developer that listens to feedback and implements meaning changes
Fantastic support
Dr.Elec
Has worked well. Does just what it needs to do and the support has been great. Helps redirect excess solar energy to charge your car rather than the grid.
No charge on solar no problem

This app makes charging for the most part easier especially if you only want to charge on excess solar
• Three-phase charging support. SundialEV now recognizes three-phase power on its own and sizes charging correctly for it. Primarily for users outside North America.
• More ways to connect: Added support for Emporia Vue, Solis, Growatt and Sense energy monitors, so more homes can measure their surplus.
• A dashboard that shows its work. The car now carries a live ring that sweeps while power is flowing. When your wall charger is the thing capping the rate, the app now says so instead of leaving you to wonder and clearer explanations for why charging is waiting or paused, including when solar is climbing back after cloud cover.
