Key benefits

  • Handles surge loads from pumps and motors without interruption.
  • PowerAssist adds battery power on top of the AC input when loads exceed it, and diverts extra AC to charging when they do not.
  • The second AC output only runs when AC input is present, which keeps heavy loads off the battery.

Key features

  • 12V battery input, 3kVA, 120V AC output
  • 120A battery charger
  • One AC input and two AC outputs
  • PowerAssist and PowerControl
  • Programmable automation in VictronConnect, such as switching a fan by temperature
  • UL1741 certified

Ideal use

12V grid-tied, off-grid, or mobile systems with critical loads on one output and non-essential loads, such as a water heater, on the other.

From the manufacturer

About the Victron Energy MultiPlus-II 12V 3kVA Inverter Charger Victron’s 12V MultiPlus-II 3kVA 120V 120A inverter-charger is UL1741 certified and is ideal for mobile applications, solar power systems, or off-grid systems. It has one AC input and two AC outputs. The Multiplus-II is a low frequency inverter with an unprecedented idle consumption of 13W. It’s rated for 2.4kW continuous output that peaks at 5.5kW. This enables pumps, motors, or other high surge items to draw needed power without interruptions or system failures. In addition to handling high surges, the MultiPlus-II is highly programmable through the VictronConnect software. These features enable automated programming, such as activating a fan when the temperature reaches a certain level. PowerAssist and PowerControl PowerAssist and PowerControl settings control incoming power and outgoing power. PowerControl limits power intake when incoming power is limited, and PowerAssist monitors the system for maximum efficiency. PowerAssist continuously monitors incoming power, battery charge, and load requirements to provide extra power if needed. When load demands are greater than incoming AC, the inverter adds up to 2.4kW in addition to the existing AC input. When incoming power is more than the loads consume, PowerAssist automatically diverts extra AC power to battery charging. Dual AC Outputs The MultiPlus-II powers the first AC output continuously and powers the second AC output only when power is available from either AC input. This means critical loads should be connected to the first output, and it makes the second output ideal for non-essential loads or loads that could rapidly drain a battery, such as a hot water heater. Choose Victron’s Multiplus-II for an inverter with dual outputs, numerous programmable settings, and Victron’s PowerAssist feature. It’s an excellent choice for grid-tied, off-grid, or mobile applications.
