Victron Energy MultiPlus 12/1200/50-16 120V VE.Bus - PMP122120100

The Victron Energy MultiPlus 12/1200/50-16 120V VE.Bus, manufacturer part number PMP122120100, is a multifunctional inverter/charger designed for compatible nominal 12V battery systems. It combines a pure sine wave inverter, an adaptive AC battery charger, and a high-speed automatic AC transfer switch in a single compact enclosure. This integrated design provides dependable power conversion, battery charging, and AC source management for marine, recreational vehicle, off-grid, and backup power applications.

The MultiPlus 12/1200/50-16 provides 1200VA inverter capacity, delivering up to 1000W of continuous real power at 25°C and 2400W peak power. Its pure sine wave output is designed to power compatible household electronics, lighting, small appliances, and other AC equipment while operating from a suitable 12V battery bank.

When an appropriate AC source becomes available, the MultiPlus uses its integrated 16A transfer switch to supply connected AC loads and provide battery charging. The built-in adaptive charger delivers up to 50A to the main battery bank and includes an independent 1A starter battery trickle charging output for a suitable secondary starting battery.

Important: The PMP122120100 is a 12V inverter/charger with 120V AC output. It is not a standalone solar MPPT charge controller. Its inverter capacity is specified in VA and watts, and connected equipment must remain within the applicable continuous, peak, thermal, and battery-system limits. External GX devices, monitoring interfaces, and optional control accessories are separate equipment unless specifically included by the seller.
