PowerControl Allows setting a maximum AC input current, prioritising AC loads and using remaining power for battery charging, preventing overload of the AC source. PowerAssist Supplements the capacity of a limited AC power source (e.g., generator or shore power) by drawing additional current from the battery during peak load demands. Storage Mode Activates after 24 hours of no discharge, reducing float voltage to minimise gassing and corrosion, with a weekly equalisation charge to prevent stratification. BatterySafe Mode Prevents damage from excessive gassing during rapid charging by automatically limiting the rate of voltage increase once the gassing voltage is reached. WeakAC Function Enables the charger to accept and operate even with strongly distorted AC input voltage, at the cost of greater input current distortion. Typical Applications Application Description Off-Grid Homes & Cabins Provides reliable 230V AC power from 12V battery banks for essential household appliances in remote locations. Marine & RV Systems Integrates inverter, charger, and transfer switch for seamless power on boats, yachts, and motorhomes, utilising shore or generator power. Backup Power Systems Functions as an uninterruptible power supply (UPS) for critical loads, ensuring continuous operation during grid outages. Small Business & Workshop Powers tools, lighting, and office equipment from battery storage, providing flexibility and energy independence. Built-In Protection Functions The Victron MultiPlus 12/1600/70-16 incorporates comprehensive safety features to protect both the unit and your system. These include protection against output short circuit, overload, battery overvoltage & undervoltage, overheating, 230 VAC on the inverter output (e.g., from another AC source), and excessive input voltage ripple. Additional safeguards such as Bulk protection (limiting bulk charging time to 10 hours) and Temperature compensation (reducing charging voltage with rising battery temperature) further enhance system safety and battery longevity. Common Questions What is a pure sine wave inverter? A pure sine wave inverter produces AC power that is identical in waveform to the electricity supplied by the grid. This ensures compatibility and efficient operation for all electronic devices, including sensitive equipment like computers, medical devices, and appliances with electric motors, without risk of damage or malfunction. How does the UPS function work? The MultiPlus features a high-speed 16A AC transfer switch. In the event of a grid failure or disconnection of shore/generator power, the inverter automatically activates and takes over the supply to connected loads. This transfer happens in less than 20 milliseconds, ensuring sensitive electronics continue to operate without interruption. Can this MultiPlus charge different types of 12V batteries? Yes, the adaptive 70A 4-stage smart battery charger is microprocessor-driven and can be adjusted for various types of 12V batteries. Its adaptive function automatically optimises the charging process based on battery use, promoting longer battery life and efficient charging. What is the purpose of the PowerAssist feature? PowerAssist allows the MultiPlus to supplement the capacity of a limited AC power source, such as a small generator or shore power. If connected AC appliances require more current than the source can provide, the MultiPlus draws additional power from the battery to meet the demand, preventing overload and tripped circuit breakers. Installation Notes Professional installation by a qualified electrician is highly recommended to ensure safety and compliance with local regulations. Always refer to the detailed user manual for comprehensive wiring diagrams, installation instructions, and safety guidelines specific to the Victron MultiPlus 12/1600/70-16. Ensure adequate ventilation around the unit to prevent overheating, as it features fan-assisted cooling. Verify correct DC cabling size (50mm² battery connection) and appropriate fusing for your specific battery bank and load requirements. This inverter/charger is not supplied with cables; detailed recommendations for cable length and thickness are available in the user manual. Before You Buy Confirm your system's total power requirements (continuous and peak) to ensure the 1600VA (1300W) capacity is sufficient for your intended loads. Verify compatibility with your 12V battery bank type and capacity for optimal charging performance and system longevity. Consider any additional accessories, such as a Victron GX device (e.g., Cerbo GX) for remote monitoring or a Multi Control Panel for advanced PowerControl functionality. Plan for an appropriate mounting location, taking into account the unit's dimensions (470 x 265 x 120 mm) and its IP21 protection rating. Ensure you understand the product's features and how they integrate into your specific solar or off-grid power system. This Victron MultiPlus 12/1600/70-16 is covered by a 5-year manufacturer warranty. Always verify specifications and compatibility with your specific system requirements before purchase.
