The backbone every high-powered install needs
Before solar, battery, or EV charging can run at full capacity, your switchboard has to be up to the job. JJ certifies it to Australian Standards — then installs the rest.
An old board stalls everything downstream
Outdated fuse boxes and undersized circuits are the single most common reason solar and EV charger installs are delayed or rejected at inspection. Getting the board right first means no surprises, no rework.
Certified to Australian Standards
Full capacity from day one
Home safety, not just compliance
A correctly rated board lets solar, battery, and EV charger draw simultaneously at full load — no throttling, no tripped breakers.
Ageing fuse wire and overloaded circuits are a fire risk. A modern board with RCDs and circuit breakers removes that risk entirely.
Every upgrade is tested, documented, and signed off to AS/NZS 3000 — no shortcuts, no grey-area wiring.
Fully scoped, documented, and signed off
We assess your existing circuits, size the new board to handle your planned loads, and run every cable to spec. Each job is independently inspected and a Certificate of Compliance issued before we leave.
JJ holds a current NSW Electrical Contractor Licence and CEC accreditation — the credentials grid-connected installs require.
