Charge your EV on sunshine. Sundial watches your rooftop solar in real time and fills your car with the power you'd otherwise sell back to the grid for pennies.
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, Enphase solar systems (+ more now)
• 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
I have 2 Tesla vehicles & Tesla solar, but no home batteries. I got this app after a similar one closed down. I needed one that only uses excess solar to charge my car. I had a couple questions when I started, emailed support & got an immediate response. Some then we’ve exchanged emails 5-6x. Brian’s has done his best monastery questions & improve my user experience.
Extremely flexible
Mark A. Hartman
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.
More control with scheduled charging, support for Rivian EV's, and minor bug fixes.
