ampee vs Tesphase

ampee charges your electric car with your own solar power - automatically. If you have solar panels and an EV, ampee makes sure your car soaks up your surplus sunshine instead of exporting it cheaply to the grid or charging from expensive grid power. It watches your solar production in real time and continuously adjusts your car's charging speed to match the surplus - no manual tweaking, no schedules to babysit. HOW IT WORKS - Connect your vehicle: Tesla, plus Rivian, Polestar, Ford, Volvo, and Lucid - Connect your solar system or energy monitor: Enphase, SolarEdge, Fronius, Solarman, Growatt, Tesla, Sense, or Emporia - Plug in - ampee reads your surplus every 30 seconds and sets the charge rate to use it FEATURES - Solar mode: charge only on excess solar, automatically - Boost, Overnight, and Charge-to-% commands for a quick or full top-up - Departure charging: reach the level you want by the time you leave - Home-battery priority: fill your home battery first, then the car - Charge and battery limits, schedules, and export-limit awareness - Live dashboard of solar, house, car, and available power - Session history and savings: see how much solar you captured - Notifications that explain why charging started, paused, or resumed - "Ask ampee" in-app assistant for instant help ampee is free during beta. Charge on sunshine.

Tesphase is your home solar command center, see your whole system at a glance, and let it automatically charge your EV with the sunshine you're not using. Most solar owners have no idea how much power they send back to the grid for pennies. Tesphase shows you, live production, home consumption, and the excess available right now then puts that excess to work: it charges your Tesla with free solar instead of expensive grid power, adjusting in real time as the sun moves. Depending on your rates and usage, that can mean $50–$300 a month back in your pocket. ONE DASHBOARD FOR YOUR SOLAR • Live solar production and home consumption • Real-time excess solar available • Daily and monthly energy and dollar savings • Time-of-use rate awareness so you avoid peak-price charging AUTOMATIC SOLAR EV CHARGING • Starts, adjusts, and stops your Tesla's charging to match your excess solar • Pauses during peak utility hours • Full manual override any time WORKS WITH YOUR SYSTEM • Solar: Enphase, SolarEdge, Tesla Energy (Solar / Powerwall), Generac PWRcell, and Sunrun (via your underlying inverter) • EV: Tesla Model 3, Y, S, and X (any year supporting the Tesla Fleet API) HOW SETUP WORKS 1.
