Quick answer
Pi designs, installs and stands behind customer-owned solar and battery systems in South East Queensland. Every system is engineered around your consumption patterns and resilience needs, so your home runs on its own generation and storage with minimal grid reliance — and Pi's local team helps you keep it performing that way.
How it works
Designed first. Installed once. Optimised for years.
01
Consumption & resilience analysis
We start with your actual energy data and how your household runs — usage patterns, peak loads, and what staying powered means to you when the network doesn't cooperate.
02
System design
Sizing, components and architecture are engineered to your independence goals — not lifted from a template. You're paying for expert design, not generic hardware in a standard box.
03
Installation
Installed by SAA-accredited installers to AS4777 & AS5033, by the same local team that designed it — no rotating crews, no handoffs.
04
Optimisation support
After handover, Pi stays engaged — helping you understand and optimise your consumption so the system keeps performing the way it was designed to.
Why Pi — 1 of 3
Engineered for energy sovereignty, not just production
Most installers size a system to your roof and their stock list. Pi designs every system explicitly for your independence: sizing, components and architecture are engineered from your consumption patterns and resilience needs — what your household actually does, and what you need it to keep doing when the network is having a bad day.
It's the same in-house engineering capability Pi uses to design energy infrastructure at scale, applied to one home: yours. You're not paying for generic hardware — you're paying for expert design aligned with your specific independence goals.
Why Pi — 2 of 3
Post-install optimisation & sustained accountability
Ownership is incomplete without optimisation. A well-designed system still depends on how your household uses energy — so after installation, Pi stays engaged to help you understand your system and actively tune your consumption to keep it performing as designed.
You invest once; Pi stays in the picture to make sure you actually achieve the independence you paid for. That's what separates Pi from competitors who install and disappear.
Why Pi — 3 of 3
Local team, real accountability
No national company. No call centre. No rotating crews. The Pi team that designs your system is the team that installs it and answers for it — and they know your system, your area's energy dynamics, and your situation.
That ground-truth expertise drives better design decisions upfront and genuine accountability long-term. This is a partnership built on real knowledge of your home and your network area — not a transaction.
Who you're dealing with
Energy consultants and technicians. Not salespeople.
Pi doesn't employ a sales floor. The people you deal with are the energy consultants and technicians who design and build energy systems for a living — which is why the conversation starts with your data and your goals, not a pitch.

Common questions
An energy consultant works through your bills, usage patterns and independence goals, then engineers a system — sizing, components and architecture — around them. You see the reasoning behind every design decision before anything is quoted or installed.
One conversation with an energy consultant — not a salesperson — and you'll see exactly what a system engineered for your independence looks like.
