Key Features

▶  Integrated Design — Combines a powerful pure sine wave inverter, adaptive battery charger, and high-speed AC transfer switch in one unit.
▶  8000VA Pure Sine Wave Inverter — Delivers 6400W of continuous AC power from a 48V DC battery bank, suitable for sensitive electronics.
▶  110A Adaptive Battery Charger — Features 4-stage adaptive charge technology (bulk, absorption, float, storage) for optimal battery health and lifespan.
▶  100A High-Speed AC Transfer Switch — Provides Uninterruptible Power Supply (UPS) functionality, switching over in less than 20 milliseconds during power outages.
▶  PowerControl & PowerAssist — Manages limited AC input (grid or generator) by reducing battery charging or boosting output with battery power to prevent overload.
▶  Parallel & 3-Phase Capability — Allows up to six identical units to be connected in parallel for increased power, or configured for 3-phase systems.
▶  Remote Monitoring & Control — Compatible with Victron GX devices (e.g., Cerbo GX) for local and remote system management via the VRM app/portal.
▶  Auxiliary AC Output (AC-out-2) — Provides a secondary output for non-critical loads, which can be disconnected when on battery power.

The unit also features built-in anti-islanding for grid-connected applications.

Common Questions

What is the difference between VA and W for this inverter?

VA (Volt-Amperes) is the apparent power, while W (Watts) is the real power. For the Victron MultiPlus-II 8000VA, the continuous real power output is 6400W. VA accounts for reactive power, providing a more comprehensive measure of load capability, especially for inductive loads like motors.

Can this unit be used with different battery types?

Yes, the MultiPlus-II features an adaptive 4-stage battery charger that can be configured for various battery chemistries, including lead-acid (AGM, Gel, Flooded) and lithium-ion batteries. Proper configuration is essential for optimal performance and battery longevity.

Is remote monitoring available for this inverter?

Yes, when paired with a Victron GX device (such as a Cerbo GX), the MultiPlus-II can be monitored and controlled remotely via the free Victron Remote Management (VRM) app or portal. This allows for comprehensive system oversight from anywhere in the world.

What is PowerAssist and how does it work?

PowerAssist is an intelligent feature that prevents overloading of a limited AC source (like a generator or shore power). If the AC demand exceeds the source capacity, the MultiPlus-II will automatically supplement the power from the battery, ensuring continuous supply to your loads. When the load reduces, any surplus power is used to recharge the battery.

Installation Notes

  • Installation of this Victron MultiPlus-II unit should only be carried out by a qualified and certified professional.
  • Ensure all wiring adheres to local electrical regulations and manufacturer guidelines.
  • Proper ventilation is crucial for optimal performance and longevity of the inverter/charger.
  • Refer to the official Victron Energy manual for detailed installation instructions and safety precautions.

Before You Buy

  • Verify that the 48V DC input and 230V AC output specifications meet your system requirements.
  • Confirm compatibility with your existing battery bank and other solar components (e.g., MPPT charge controllers).
  • Consider the total power demand of your loads to ensure the 8000VA (6400W) continuous output is sufficient.
  • For grid-connected applications, ensure local grid operator approval and compliance with relevant standards (e.g., G98/G99 in the UK).
  • Consult with a qualified solar installer or system designer to ensure correct system sizing and configuration.

All specifications are subject to change by the manufacturer. Please verify details with the latest product datasheet. This product is covered by a 5-year manufacturer warranty.
