The Victron MultiPlus Compact 12/1200/50-16 combines a pure sine wave inverter and a battery charger in one housing, built for 12V DC systems with a 230V AC output. It suits marine, vehicle and off-grid installations where a full-size MultiPlus would take up too much space.

Key features

• Inverter output, 1200VA continuous at 230V AC from a 12V DC battery bank.
• Battery charger, 50A built-in charger with a 16A AC input current limiter for shore or generator power.
• VE.Bus communication, supports remote monitoring, VE.Configure setup, and parallel or three-phase operation with compatible Victron units.
• PowerAssist, draws extra power from the battery when AC load exceeds the available input current limit.
• Transfer switch, built in, switching from mains or generator input to inverter output during a power failure.
• Weight, 11.4 kg, compact enough for restricted mounting spaces.

Product overview

The 50A charger uses an adaptive algorithm that adjusts to battery condition, which helps battery service life compared with a fixed-rate charger. The 16A AC input current limit lets the unit run from a limited shore supply or small generator without tripping it, with PowerAssist covering the shortfall from the battery when a load spikes.

VE.Bus connectivity allows configuration through VE.Configure, integration with a Cerbo GX or Color Control GX, and use in a system where several units run in parallel or split-phase. That makes this Compact unit suitable for standalone backup as well as a larger managed installation.

The transfer switch responds fast enough to protect most sensitive loads during a mains failure. A UPS function can be enabled through software configuration for critical equipment needing a tighter transfer time.

Applications

Used on marine vessels running inverter and charger duties from a 12V house bank, in motorhomes and campervans with 230V AC appliances, off-grid cabins with occasional generator charging, and as UPS backup for sensitive equipment. It also works within managed energy systems using Victron GX devices.

Installation notes

Installation should be carried out by a qualified electrician familiar with DC battery systems and 230V AC wiring, connected to a correctly sized 12V battery bank with properly rated cabling and fusing. Grid-connected UK applications may require G98 or G99 compliance and DNO notification. Configure battery type and charge parameters in VE.Configure before commissioning, and avoid installing in enclosed spaces without ventilation.
