The Victron MultiPlus Compact 12/1600/70-16 combines an inverter and a battery charger in one unit, built for 12V DC systems delivering 230V AC output. It suits marine, vehicle, off-grid and backup installations where space is tight but reliable AC power from a battery bank is essential.

Key features

• Inverter output, 1600VA continuous at 230V AC from a 12V DC battery bank.
• Battery charger, 70A with an adaptive multi-stage algorithm that adjusts to battery condition over time.
• AC transfer switch, 16A, switching between shore or generator power and inverter output.
• PowerControl, limits AC input current draw to prevent overloading a shore or generator supply.
• PowerAssist, supplements AC input with battery power during peak demand, allowing a smaller generator or shore connection.
• VE.Bus interface, for integration, remote monitoring and configuration via Victron GX devices or VEConfigure software.
• Weight, 11.5 kg, suited to restricted mounting spaces.
• Supports parallel and three-phase operation when multiple units are combined.

Product overview

The unit pairs a sine wave inverter with a high-current charger and an AC transfer switch. Connect an AC source, such as shore power or a generator, and it charges the battery bank while passing AC through to loads. Lose that source and the transfer switch takes over. The 70A charger runs Victron's four-stage bulk, absorption, float and storage algorithm, adjusting absorption time to the previous discharge to reduce unnecessary charge time. It works with flooded, AGM and gel lead-acid batteries, and can be set up for lithium via VEConfigure.

VE.Bus lets the MultiPlus Compact join a larger Victron system. Monitor and control it through a Victron GX device such as the Cerbo GX, or configure it remotely via VRM. Connect several units in parallel for more capacity, or set up split-phase or three-phase output where the installation calls for it.

Applications

• Marine vessels needing 230V AC power from a 12V battery bank.
• Motorhomes and campervans with shore power and battery backup.
• Off-grid cabins and remote buildings with battery storage and generator input.
• UPS and backup power for critical equipment.
• Mobile and vehicle installations where compact dimensions matter.

Installation notes

Installation should be carried out by a qualified electrician or accredited installer experienced with DC battery systems and 230V AC wiring. Connect the unit to a correctly rated 12V battery bank with properly sized DC cabling and fusing. For any grid-connected or shore-power use in the UK, follow current wiring regulations. Set battery type, charge parameters and system settings with VEConfigure before commissioning.
