Victron MultiPlus-II 48/15000/200-100 230V PMP483150000

PowerAssist Technology
The PowerAssist feature prevents overload of a limited AC power source, such as a generator or shore power connection, by:

• Reducing Battery Charging: When an overload risk is detected, the MultiPlus-II automatically reduces battery charging to prevent tripping the supply source.
• Boosting Output: If necessary, the inverter supplements the AC source using power from the batteries, effectively boosting the output to support high-demand loads.

This dual functionality guarantees stable power delivery, protecting the system from overload and maintaining continuous power even under heavy loads.

Energy Storage System (ESS) Integration
The MultiPlus-II plays a pivotal role in a Victron ESS setup, enabling seamless integration with:

• MPPT Solar Chargers for maximum solar energy utilization.
• Grid-tie PV Inverters to enhance self-consumption of generated solar power.

The system intelligently manages energy flow to prioritize self-consumption, optimize efficiency, and reduce dependency on the grid. It is particularly beneficial for hybrid systems where grid, solar, and battery power are combined for cost-effective energy solutions.

Uninterrupted AC Power (UPS Function)
In the event of a grid failure, or disconnection from shore power or a generator, the MultiPlus-II seamlessly switches to inverter mode, ensuring uninterrupted power supply to connected loads. This transition occurs in less than 20 milliseconds, making it ideal for sensitive electronics such as:

• Computers
• Servers
• Medical Equipment
• Home Appliances

This UPS functionality ensures uninterrupted operation, protecting sensitive devices from data loss or damage due to power interruptions.

Remote Monitoring and Control
With the addition of a Cerbo GX or Color Control GX, users gain advanced monitoring and control capabilities:

• Local Monitoring: Via LAN, allowing on-site system management.
• Remote Monitoring: Through the free VRM app or VRM portal, accessible from anywhere in the world.
• Multi-Device Compatibility: Compatible with smartphones, tablets, laptops, and PCs.
• Comprehensive Control Options: Users can adjust settings, monitor energy usage, and even auto-start a backup generator remotely.

This advanced monitoring capability provides complete oversight and control over the energy system, enhancing convenience, efficiency, and security.

Solar Energy Integration
The MultiPlus-II is designed to work seamlessly with solar energy systems, enabling:

• Off-Grid Functionality: Ensures continuous power supply even when disconnected from the grid.
• Grid-Tied Compatibility: Works with grid-connected PV systems for optimal energy management and self-consumption.
• Hybrid Energy Solutions: Combines solar power, grid power, and battery storage to maximize energy efficiency and reduce electricity costs.

The system is compatible with both solar charge controllers and grid-tie inverters, providing a flexible solution for a variety of energy scenarios.

External Current Transformer (Optional)
The MultiPlus-II supports an external current transformer for enhanced functionality:

• PowerControl: Monitors and controls grid or generator current usage, ensuring the power source is not overloaded.
• PowerAssist: Supplements the AC supply using power from the battery when needed, preventing tripping.
• Optimized Self-Consumption: Utilizes external current sensing (up to 32A) to prioritize self-generated solar power for self-consumption.

This feature enhances system intelligence and adaptability, making the MultiPlus-II a versatile and dynamic power management solution.

Anti-Islanding Protection
For grid-tied applications, the MultiPlus-II includes built-in anti-islanding protection, which:

• Prevents the inverter from feeding power to the grid during a power outage, ensuring the safety of utility workers.
• Complies with international safety standards and country-specific regulations for grid-connected systems.

This safety feature is essential for compliance and safe operation in grid-tied solar or hybrid systems.
