MultiPlus-II 12/4k 160-32 230V

The MultiPlus-II 12/4k/160-32 230V is an advanced 12V, 4kW inverter-charger from Victron Energy. It combines a pure sine wave inverter, a powerful 160A battery charger, and an automatic UPS switch with near-interruptible switching (transfer time less than 20ms) in a single, compact package.

Main advantages:

• Continuous power 3400 W / peak power 6000 W


• Intelligent PowerControl and PowerAssist functions


• Automatic UPS mode - instant switching to battery power


• Possibility of parallel and three-phase operation (up to 6 units)


• Full integration with ESS (energy storage) systems


• Remote monitoring and configuration via Victron VRM and the VictronConnect app


• Two AC outputs - one uninterrupted, the other only when mains is present


• High efficiency and solid construction

The MultiPlus-II 12/4000/160-32 is the heart of a modern energy system – both in off-grid installations and hybrid energy storage systems. Thanks to PowerAssist features, it copes perfectly with limited power sources (weak grid, small generator), and the ability to expand the system in parallel or three-phase makes it a highly future-proof solution.
