Forming our pilot network · Sydney, NSW
Your roof already makes the power. Let it earn.
Phi installs a home battery and a small compute node at your home, with no upfront hardware cost. It runs AI workloads on your midday solar, powers your home through the evening peak, and supports the grid when it's under stress. You share in the value through lower power bills.
Two broken systems
NSW has too much solar at noon. AI can't get enough power at all.
IPART's 2026–27 benchmark for NSW solar exports, per kWh. Retailers don't have to pay even that. The panels you paid for earn less every year.
Midday solar floods the network and drives wholesale prices down. New NSW rules from late 2026 let networks curtail rooftop solar in grid emergencies.
AI needs power, land and grid connections that take years to secure. Meanwhile, the energy it needs is sitting on suburban rooftops.
How it works
One node. Three jobs. Every day.
Tell us about your roof, solar system and internet. We confirm whether your home suits the pilot.
A weatherproof unit holding a battery and compute module, fitted by licensed electricians. Phi funds the hardware.
Our software decides minute by minute whether your solar should run compute, charge the battery, power your home or support the grid.
A day in the life of a Phi home
IllustrativeLow-priority compute runs only when grid power is cheapest.
Early solar covers breakfast-time load before anything else.
Surplus solar that would be exported for a few cents powers compute and fills the battery.
Stored solar powers your home. When prices spike, compute pauses and power goes to the grid.
For homeowners
Lower bills without buying a battery.
You provide a small footprint beside your home and access to your solar. Phi provides the hardware, the installation and the software, and passes savings back to you.
Pilot terms, including your savings share and contract length, will be set out in writing before anyone signs anything.
For investors & partners
A distributed compute utility, built on roofs that already exist.
No land to buy, no concrete shells, no high-voltage connection queue. Capital goes straight into hardware that earns from the day it is installed, deployed in days rather than years.
Batch and latency-tolerant workloads run on near-zero marginal cost solar at the point of generation.
Store cheap midday energy, dispatch into NEM evening peaks and price spikes.
An aggregated fleet that can pause load and discharge on signal, participating in FCAS and demand response.
Phi is raising a pre-seed round. Angels, climate funds and strategic partners can request the deck.

We're choosing pilot suburbs now. Joining is free and doesn't commit you to anything. Investors and partners can use the same form.
You're on the list.
We'll be in touch as we confirm pilot suburbs. Thanks for backing a better way to power AI.
Not yet. We're forming a pilot network in Greater Sydney and will contact waitlist members as pilot suburbs open.
Your home is always served first. Phi only uses the surplus you would otherwise export for a few cents per kWh.
