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 ## Key features - Charges EV with surplus solar - Avoids grid export for low rates - Set charging floor and battery reserve - Works with all Tesla models - Coordinates with Powerwall - Utilizes off-peak charging ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/sundialev/id6782257870/reviews.md ### 5/5 — Great app *2026-08-12* Works to utilize my solar to charge my car!

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. ### 1.10.1 — 2026-08-13 More polished new-user setup flow and updated nav chrome. ### 1.10.0 — 2026-08-11 A new way around the app. • Floating tab bar — Dashboard, Trends and Settings now sit in a compact bar that floats above your content instead of pinning a heavy bar to the bottom of the screen. • Notifications inbox — tap the bell to see everything Sundial has told you, including alerts you've already dismissed. • Clearer stop explanations — when Sundial stops a charge, it now tells you why instead of leaving you guessing. • All-day avoid windows — set a window's start and end to the same time to block charging for a full 24 hours. • Faster app opens, with fewer redundant refreshes when you switch tabs. ## More apps by AppAhead - [Healthy Balance Fitness](https://appshunter.io/ios/app/healthy-balance-fitness/id379575022) - [Fran's Feed](https://appshunter.io/ios/app/frans-feed/id388870781) - [TT Photo](https://appshunter.io/ios/app/tt-photo/id407714802) All apps by AppAhead: https://appshunter.io/developer/379575025 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
