Your roof, on the market, in a week.
There is no electrician, no new inverter and no contract. A small box, a floor price you set once, and a Friday deposit. Here is exactly what happens.
Three steps. Zero electricians.
Everything you need already lives on your roof or in your garage. We just give it a shop window.
Plug in
Snap our little box onto your inverter or battery. It sees what you're not using — and only that.
Name your price
Set a floor. Buyers bid above it every 15 minutes. You do nothing.
Get paid Friday
Straight to your bank. Average seller: $214 a month.
Inside a 15-minute block
The market runs in quarter-hour blocks, all day, every day. This is one of them.
- 00:00
Measure
The gateway reads your inverter or battery once a second and works out what you will not use in the next 15 minutes.
- 00:05
List
That surplus goes on the board at your floor price. Nothing below the floor is ever offered.
- 00:05 – 14:30
Auction
Utilities, businesses and neighbours bid above your floor. Highest bid wins the block. You do nothing.
- 15:00
Settle
The block clears. Your sale is logged with the buyer, the kWh and the price, and shows up in your feed.
- Friday
Payout
Every settled block from the week is added up, the 6% fee comes off, and the rest lands in your bank.
What the gateway sees
It watches one thing: the power leaving your home that you are not using. It never touches what your house draws, never controls your appliances, and never sells a watt you need.
- Clips to almost any inverter or battery made since 2015
- Talks over the cable your system already has
- Powered by the inverter — nothing to charge
- Free while you sell. Return it any time.
The maths, plainly
One fee, taken only when something sells. If nothing sells you pay nothing.
Common questions
All questions →No. The gateway clips onto almost any inverter or battery made since 2015 and talks to it over the wire it already has.
Full answer →Utilities, businesses on your local grid, and neighbours who'd rather pay you than the utility. They bid; you win.
Full answer →Nothing sells and the power goes to your utility at their normal rate, same as today. You never do worse than before.
Full answer →Yes, if your car and charger support bidirectional charging. You set how much charge to keep, and the rest goes on the board.
