Victron Energy MultiPlus-II 48/10000/140-100/100 230V Inverter Charger – PMP483105000

Product Overview

The Victron Energy MultiPlus-II 48/10000/140-100/100 230V is a high-capacity inverter charger for 48V battery systems. Combining a pure sine wave inverter, 140A battery charger and 100A AC transfer switch, it is designed for off-grid solar, residential energy storage, commercial installations and backup power.

With a 10,000VA inverter rating and continuous output of 8000W at 25°C, it converts 48V DC battery power into 230V AC electricity. PowerControl, PowerAssist and UPS functionality help manage available power and maintain the supply to suitable connected equipment during a mains interruption.

Key Features and Applications

The MultiPlus-II combines inverter power, battery charging and AC switching in one unit. It is suitable for off-grid homes, solar energy storage, generator-backed systems, commercial installations and compatible marine applications.

PowerControl limits current drawn from an external AC supply, while PowerAssist supplements available power with battery energy when demand increases. Two AC outputs allow essential and non-essential loads to be managed separately in suitable installations.

VE.Bus communication supports integration with compatible Victron Energy equipment. Compatible parallel and three-phase configurations allow systems to be expanded for greater power requirements.
