The large off-grid system, for a house that cooks and cools
The Mac-Daddy is the large system. It is the one for a house that wants the induction cooktop and a small air conditioner in the same design, and often a workshop as well. The old product address still says 3 kVA in the web slug. The pages recovered under that address describe the big Victron system, and that is the Mac-Daddy this page is for.
What you can run
A kettle, an induction cooktop, a small air conditioner, and the workshop. What may run at the same time is still a design question. This is the size where those loads belong in the one conversation.
What the old listings said
The archived pages describe a large Victron system built around a 15 kVA Quattro. kVA is the inverter size, the box that turns battery power into household power. The solar array started around 10 kW and the copy talked about going much larger. The battery figure is not the same on every snapshot, so it is not printed here.
Single-phase or three-phase was a choice. Three-phase means three live wires, the supply a larger home or a workshop often has. The gear was prewired on a board. We design it for the property now, rather than shipping one old parts list.
How we work
We design the system in Lismore. A vetted, accredited local partner installs it.

Common questions
What is the Mac-Daddy?
The large off-grid system. Induction, a small air conditioner and a workshop are the loads it was aimed at. The old web address looks like a small 3 kVA kit. The recovered pages are the big Victron system.
What can it run?
A kettle, an induction cooktop, a small air conditioner and workshop loads, with the design saying what runs together.
Why is there no price and no single battery number?
Old listings moved, and prices are not published on this site. The design comes back with a system sized to the property.
