Description
MultiPlus-II 48/15000/200-100 230V
The Victron MultiPlus-II 48/15000/200-100 is the heavyweight champion of the MultiPlus-II range, designed for serious off-grid power, large-scale energy storage systems (ESS), and high-demand professional applications.1 Combining a powerful 15kVA pure sine wave inverter, an advanced 200A battery charger, and a high-speed AC transfer switch in one compact enclosure, it provides the ultimate foundation for a robust 48V system.
At LiFePO4 Australia, we recommend this unit for users who need to run heavy loads—such as air conditioners, workshop tools, or large domestic appliances—without the fear of tripping or overloading.
Key Features
Massive Surge Capability: With a peak power rating of 27,000W, this unit handles the high start-up currents of inductive loads like pumps and compressors with ease.
PowerAssist & PowerControl: Prevent overloading a limited AC source (like a small generator or shore power). PowerAssist allows the MultiPlus-II to “boost” the AC source with battery power when demand exceeds the supply.
Dual AC Outputs: The main output features “no-break” functionality, taking over the load in under 20ms during a power failure.7 The second output is only active when AC input is present, perfect for non-critical loads (like water heaters) that shouldn’t drain your batteries.
ESS Ready: Fully optimized for Energy Storage Systems, allowing for seamless integration with solar chargers and grid-tie inverters to maximize self-consumption.
LiFePO4 Optimized: Seamlessly integrates with smart LiFePO4 battery banks. When paired with a GX device (like the Cerbo GX), you get full visibility and control over your battery’s state of charge and health.

Why Choose the 15kVA MultiPlus-II?
For large-scale Australian off-grid setups, the 15kVA model offers a significant advantage: simplicity. Instead of paralleling multiple smaller units, a single 15kVA unit reduces cabling complexity and footprint while providing enough continuous power (12kW) to run a standard modern home entirely off-grid.
Pro Tip: To get the most out of this unit, we recommend pairing it with a Victron Cerbo GX and a high-quality LiFePO4 bank for 24/7 remote monitoring and system fine-tuning via the VRM Portal.11
