PRODUCT DESCRIPTION
Victron Energy MultiPlus 12V 1200VA 50A Pure Sine Wave Inverter Charger 120V VE.Bus – PMP122120100
The Victron Energy MultiPlus 12/1200/50-16 120V VE.Bus is a 12V pure sine wave inverter charger that combines a 1200VA inverter, a 50A adaptive battery charger, and a 16A automatic AC transfer switch in one compact unit. It delivers clean 120V AC power, smart battery charging for lithium and lead-acid batteries, and fast switching between shore power, generator power, and battery power for RV, marine, off-grid solar, and backup power systems.
Victron PowerAssist and PowerControl let the MultiPlus make the most of limited shore or generator power. PowerControl caps the AC input current to prevent tripped breakers, and PowerAssist adds battery power during peak demand. With 2400W surge capacity, parallel and three-phase capability, and remote monitoring through Victron GX devices and VRM, this 12V inverter charger fits both small mobile systems and expandable off-grid installations.
Key Features
- 1200VA / 1000W Pure Sine Wave Inverter: Clean, stable 120V AC output (±2%) for sensitive electronics, appliances, and critical equipment.
- 50A Adaptive Battery Charger: Four-stage adaptive charging for lithium and lead-acid battery banks, supporting longer battery life.
- 16A Automatic Transfer Switch: Switches automatically between shore power, generator power, and inverter operation.
- PowerAssist: Adds battery power to limited shore or generator power during high-demand periods to prevent overloads.
- PowerControl: Manages AC input current to help keep shore and generator breakers from tripping.
- Dual Battery Charging: Charges the main house battery bank plus a starter battery through a separate 1A trickle charge output.
- 2400W Peak Surge Power: Handles high-inrush loads such as motors, compressors, pumps, and power tools.
- Search Mode: Lowers idle power consumption when no AC load is detected.
- Programmable Relay: Configurable for alarms, low battery voltage alerts, generator auto-start, and other system functions.
- Parallel and Three-Phase Operation: Connect up to six units in parallel, or configure three units for a three-phase system.
- Remote Monitoring and Configuration: Compatible with Cerbo GX and other GX devices, Victron VRM, VE.Bus Smart Dongle, and VEConfigure.
- DIP Switch Setup: Adjust key settings directly on the unit, or use VE.Bus for advanced programming.
- Built-In Protection: Protects against overload, short circuit, high temperature, battery overvoltage and undervoltage, and excessive input ripple.
- Battery Temperature Sensor Support: Enables temperature-compensated charging.
