How it's wired

One integrated system — programmed before it ships.

Two MultiPlus-II inverters run in parallel for the 10 kVA continuous output, with the SMA Sunny Boy 6 kW PV inverter feeding solar straight to the AC bus when the sun is up. The Victron 250/45 SmartSolar MPPT handles DC-coupled charging into the battery bank.

The Cerbo GX controller manages it all — generator hand-off, battery state of charge, load shedding — and pushes live telemetry to your phone via the Victron VRM dashboard whenever the system is online.

What's included

Everything you need, in one shipment.

Each kit ships as a complete package — inverters, batteries, panels, racking and balance-of-system parts, all pre-integrated and programmed. Designed for straightforward installation by a CEC-accredited solar electrician.

Standards & install

Built to Australian standards.

System wiring complies with the relevant AS/NZS standards listed below. Your installer's electrical certificate covers the final installation.

  • AS/NZS 3000 (or 3001 transportable) — Electrical installations
  • AS/NZS 4509 — Stand-alone power systems
  • AS/NZS 5139 — Battery installations
  • AS/NZS 5033 — Installation of photovoltaic arrays
LV (low-voltage) work — including any solar array above 120 V dc — must be carried out by a licensed electrician. Compliance with the standards above is the installer's responsibility; check the rules in your state.
