Victron Energy MultiPlus 12/800/35-16 inversor/cargador 12V 800VA 35A cargador 16A Transfer

The Victron Energy MultiPlus 12/800/35-16 is a combined inverter and battery charger for 12V systems that delivers up to 800 VA of continuous inverter output while integrating a multi-stage 35 A battery charger and an automatic 16 A uninterrupted transfer function. Designed for applications where compact, reliable AC power and intelligent charging are required, this unit supports off-grid, marine and recreational vehicle installations. The device synchronizes with shore or generator power, converts battery DC to AC when needed, and recharges batteries with configurable charge algorithms for lead‑acid and other battery types.

Advantages

The integrated design reduces installation space and wiring compared with separate inverter and charger units, while the MultiPlus topology provides seamless switching between inverter and external AC source without interruption to sensitive loads. The unit includes configurable charging profiles and power management features that optimize battery life and system performance. Its electrical protection and thermal management help ensure reliable operation under varying load and environmental conditions.

How to use

Install the MultiPlus 12/800/35-16 according to the manufacturer's wiring and mounting instructions, ensuring correct polarity, adequate DC cable sizing and secure AC connections. Configure battery charging settings and transfer behavior to match the battery type and system requirements, using available communication options or on-unit controls. When AC input (shore or generator) is present, the unit will charge the battery and supply loads; when AC input is absent it will invert DC battery power to AC output automatically. Regular inspection of connections and battery condition supports dependable operation.

Recommendations

Use appropriately sized fuses or circuit breakers on DC and AC circuits, select cable gauges to minimise voltage drop, and set charging parameters to match the battery manufacturer's specifications. For installations with solar arrays or external power sources, integrate proper system monitoring and, where required, configure power assist or prioritisation features to prevent overloads.
