Victron MultiPlus-II
The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid. It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A).
It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals. The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection.It supports parallel or three-phase configurations, is remote-manageable via GX/VRM, and now appears on the Clean Energy Council’s approved inverter list for STC eligibility. For a short period of time this product was called MultiGrid-II.

About Victron MultiPlus-II Inverter
The MultiPlus-II created by Victron Energy is a brand that enjoys the rare virtue of European durability and remote energy management; hence it combines the best features of an inverter and a charger into one compact, scalable device. Whether you are a homeowner in rural WA, a small business in South Australia, or building an off-the-grid cabin in Tasmania, the Victron MultiPlus-II offers solid control of energy tailored to Australian conditions.
The Victron MultiPlus-II acts as a hybrid inverter and battery charger, smartly managing energy flow from solar panels, batteries, and the grid. It is mostly suitable for homes, off-grid cabins, and commercial sites looking for energy independence or backup power in case of a grid outage.
The MultiPlus-II, unlike typical inverters, charges batteries and powers the home at the same time, switching in milliseconds between the two sources. It is scalable for anything from a tiny house in Tasmania to a full-sized Queensland family home, with models going from 3 kVA to 15 kVA.
Note: for a short period of time this product was called MultiGrid-II.
