The Victron MultiPlus Compact 24/1600/40-16 is a combined inverter and battery charger built into one housing for 24V battery systems. It delivers a 1600VA inverter output with a 40A charger, and is sized for installations where space and weight matter, such as marine or vehicle conversions.

Key features

• Inverter output, 1600VA continuous at 230V AC, with a 3000W peak surge for motor start loads.
• Battery charger, 40A three-stage charging (bulk, absorption, float) with an adaptive charge algorithm.
• AC transfer switch, 16A, switching between shore power or generator and inverter mode.
• VE.Bus interface, connects to Victron GX devices and VEConfigure software for monitoring and configuration.
• PowerControl, limits total AC current draw to avoid overloading a generator or shore supply.
• PowerAssist, draws on the battery to supplement shore or generator power during peak demand.
• Weight, 11.4 kg.

Product overview

The unit runs a true sine wave inverter alongside a multi-stage charger. With AC input present, it charges the battery bank and passes power to connected loads. When AC input is lost, it switches to inverter mode automatically, fast enough to keep most computers and sensitive electronics running through the changeover.

VE.Bus allows several MultiPlus units to be configured together for more capacity, or arranged in split-phase or three-phase setups. It also links to Victron GX monitoring devices such as the Cerbo GX, giving visibility of battery state of charge and AC input and output data.

PowerControl and PowerAssist help where the available AC supply is limited. PowerControl caps charger current so a shore breaker does not trip. PowerAssist adds battery power during short demand peaks, letting a 16A shore connection support loads that would otherwise exceed it.

Applications

• Off-grid cabins and remote buildings with 24V battery banks needing generator charging and AC power.
• Marine installations wanting shore power charging and inverter backup in a lightweight unit.
• Motorhomes and expedition vehicles requiring 230V AC from a 24V house battery.
• Backup power for communications, medical or security equipment.
• Small off-grid solar systems paired with a charge controller and GX monitoring device.

What's included

• 1x Victron MultiPlus Compact 24/1600/40-16 230V VE.Bus inverter charger unit

Installation notes

Installation should be carried out by a qualified electrician or accredited installer familiar with DC battery systems and 230V AC wiring. The unit must connect to a correctly fused and rated 24V battery bank. Where it forms part of a grid-connected solar or backup system, relevant UK wiring regulations and any applicable G98 or G99 requirements apply. VEConfigure software is needed for advanced configuration.
