Off-grid Kits - Ready for Installation

Transfer Solar’s pre‑built power systems give Victorian homes, farms, and off‑grid businesses the convenience of a pre‑assembled system without sacrificing true custom design. Each unit arrives fully wired, fully programmed, and tested in our workshop, so all you (and your electrician) need to do is lift it into place, connect the arrays, batteries, loads, and switch on.

Why Choose a Transfer Solar Pre-Built System?

  • Tailored, not one‑size‑fits‑all – Unlike other pre-built boards, every system is designed and engineered to suit your load requirements, future expansion plans, site conditions, and budget.

  • Regulation‑ready – Pre‑wired to AS/NZS 3000, AS 4777, and the latest Clean Energy Council & SAA requirements—including compliance for the new National Battery Rebate scheme (if applicable).

  • Local expertise – Designed and tested in Kinglake, delivered across north‑east and central Victoria, and (if you wish) installed by our SAA‑certified electricians.

  • Competitive pricing: Systems start from $12,800 for a 5kVA Victron inverter, 10kWh Pylontech battery, and 3.5kW solar array (fully modular, expandable, indoor system ready to mount).

Delivery & Installation

We deliver across north‑east and central Victoria on pallet skids or enclosed trailers for a reasonable fixed fee. If you’d rather leave the installation to the experts, our SAA-accredited team can mount, cable, and commission the systems and panels on-site, completing all necessary compliance paperwork for the National Battery Rebate and Victorian DNSP approvals (if required).
