Quick questions.
Everything you need to know before connecting your solar and your car — setup, pairing, and privacy.
What do I need to get started?
A California home with solar (Enphase today), a Tesla, and your phone. No hardware, no installer, no site visit.
How does setup work?
Three steps, about five minutes: sign in to your solar account, sign in to your Tesla account, then pair your car so Tesphase can manage charging. After that it runs on its own.
What's the "pair your car" step?
Tesla requires you to approve a virtual key in the Tesla app before any app can adjust your charging. It's one tap, once per car, and you can revoke it from the Tesla app anytime. Until a car is paired, Tesphase can only watch — not charge.
We have two cars — which one does Tesphase charge?
Only the cars you choose to pair. Pair one or both; a car you haven't paired is never touched.
Do you ever see my passwords?
No. You sign in on Tesla's and your solar brand's own pages, and you can disconnect either account from Tesphase whenever you like.
