Victron Energy MultiPlus 12/500/20-16 230V VE.Bus Inverter Charger – PMP121500000

Product Description

The Victron Energy MultiPlus 12/500/20-16 230V VE.Bus Inverter Charger (PMP121500000) is a compact, integrated power solution combining a pure sine wave inverter, adaptive battery charger and automatic AC transfer switch in one unit. Designed for 12V battery systems, it converts DC battery power into reliable 230V AC electricity while also charging the battery when a suitable mains or generator supply is available.

With a 500VA inverter capacity, a maximum battery charging current of 20A and a 16A transfer switch, the Victron MultiPlus is suited to smaller off-grid installations, marine electrical systems, campervans, motorhomes and backup power applications where dependable AC power and efficient battery charging are required.

The built-in uninterruptible power supply (UPS) function automatically switches to inverter operation when the incoming AC supply fails. Its fast transfer time helps maintain power to connected equipment, while the VE.Bus communication interface supports integration with compatible Victron monitoring, configuration and system-control equipment.

The MultiPlus combines three essential power functions in one compact enclosure, helping simplify system design and installation while reducing the need for separate inverter, charger and transfer-switch components.
