How Tesphase works.
Tesphase watches your solar in real time and quietly sends the extra into your EV — live, all day, without you touching anything.
1
Connect
Sign in once to your solar system and your EV. Five minutes, from your phone — no installer, no hardware, and we never see your passwords.
2
We optimize
Tesphase watches your solar and your home's usage live, then sends the extra to your EV — timed around your utility's rates and gentle on your battery.
3
You save
Most homes get $100–300 back every month. Your dashboard shows exactly how much solar you kept and what it saved you, week by week.
