● Commercial Solar & Battery Systems
Commercial solar PV and battery storage is a specialist trade. We refer to CEC-accredited commercial-scale partners and handle the surrounding electrical work — switchboard upgrades, sub-mains, EV integration, and metering.
- —Honest referral to a CEC commercial-accredited installer or EPC we'd use ourselves
- —Pre-quote sanity check of your switchboard, sub-mains capacity, and metering compatibility
- —Quote review against AS/NZS 4777.2, AS/NZS 5033, and AS/NZS 5139 — inverter, DC isolators, PV array, and battery cabinet selections
- —Coordination of the surrounding electrical scope — switchboard upgrades, sub-mains, EV charger integration, and separately-metered sub-circuits
- —Pre-build site survey for cable run, connection-point, and DNSP application coordination with the EPC
- —Commissioning support and metering verification once the system goes live
What working with us looks like.
Commercial work is different — out-of-hours access, contractor sign-in, induction paperwork, working at heights, and the EWP isn't always on site when you need it. We've worked with dozens of head contractors and we're used to the rhythm: WHS pack, COC and ESV lodgement, daily SWMS sign-off if that's the protocol on your job.
Variations and RFIs get a same-day turnaround — never more than twenty-four hours. If we genuinely can't, we'll tell you straight away rather than dragging it out. Defects window: twelve months on labour, manufacturer warranty on parts, same-day site attendance for any issue raised during business hours.
Insurance: $20m public liability, $10m product liability, full PI for any design work we touch. Certificates of currency available on request. ABN, REC and trade licences are all on the licensed contractor card on the about page.
Builder,
owners corp,
-or-
architect?
Repeat work across multiple sites warrants a different arrangement — unit rates, scheduled RFI turnaround, a single point of contact.
