Victron Energy MultiPlus 48/2k/30-32 Hybrid Inverter/Charger – is a cutting-edge 48V multifunctional 2 kW power unit that combines a high-precision pure sine wave inverter, an advanced 4-stage adaptive battery charger (30 A), and an ultra-fast 32 A AC transfer switch in a single compact enclosure. Equipped with PowerAssist and PowerControl technologies, it dynamically optimizes shore or generator power and supplements it with battery energy during peak loads.
This model is designed for 48V battery banks (including popular LiFePO4 rack batteries such as Pylontech, Dyness, BYD, etc.) and serves as an ideal solution for residential uninterruptible power supplies (UPS), hybrid solar energy storage systems (ESS), server rooms, telecom infrastructure, and commercial sites. Operating at 48V ensures exceptional efficiency (up to 95%), lower operating currents, and reduced cable losses.
Thanks to the VE.Bus communication bus, the MultiPlus easily integrates into scalable energy systems supporting parallel operation (up to 6 units per phase) and 3-phase 380/400V configurations.
Key Benefits of the MultiPlus 48/2k/30-32 Inverter
-
48V Architecture with up to 95% Maximum Efficiency – reduced cabling losses, lower operating heat, and native compatibility with 48V LiFePO4 server rack batteries.
-
2000 W Continuous Power (Peak up to 4000 W) – dependable 2000 W output at 25 °C with pure sine wave voltage and high start-up capacity for demanding inrush loads such as pumps, refrigerators, and power tools.
-
Intelligent 30 A Battery Charger – safe and fast charging for all 48V battery chemistries (LiFePO4, AGM, GEL, Flooded) with an adaptive 4-stage charging profile and Storage Mode.
-
High-Speed 32 A AC Transfer Switch – seamless transfer to battery backup (less than 20 ms) guarantees uninterrupted operation of sensitive IT, medical, and audio/video equipment without resets.
-
PowerAssist Function – automatically boosts limited generator or grid capacity by drawing additional power from the 48V battery bank during peak demand.
-
PowerControl Function – sets a maximum input current limit from the AC source and allocates spare capacity to battery charging, preventing circuit breaker tripping.
-
VE.Bus Parallel and 3-Phase Capability – scale system capacity by connecting up to 6 units in parallel or create a 3-phase 400V power network.
-
Multi-Functional Programmable Relay – dry contact for automatic generator start/stop, low battery alarms, or non-critical load shedding.
-
Search Mode Energy Saving – reduces no-load idle consumption from 13 W down to just 3 W (approx. 70% energy reduction).
-
Remote Monitoring via VRM Portal – full remote monitoring, real-time analytics, and firmware configuration via smartphone or PC.
Technical Features
PowerAssist – Boosting Limited Grid or Generator Capacity
- This feature enables the MultiPlus to operate in parallel with an AC source. When peak loads exceed the capacity of the shore supply or generator, the MultiPlus instantly supplements the deficit with energy from the 48V battery bank. Once the demand drops, surplus AC power is redirected back to battery recharging.
PowerControl – Intelligent Power Balancing
- Using the Digital Multi Control panel or the VictronConnect app, a maximum input current limit can be set. MultiPlus continuously monitors total AC demand and automatically adjusts the battery charging current, preventing source overloads and nuisance breaker trips.
4-Stage Adaptive Battery Charger (30 A / 48 V)
- The charging system features Absorption (57.6 V), Float (55.2 V), and Storage mode (52.8 V). The adaptive charging software automatically tunes the absorption period according to the depth of discharge, while Storage mode prevents plate corrosion and extends battery service life.
High Start-Up Power (Up to 4000 W Peak)
- Engineered to easily handle high inrush currents, making it ideal for starting demanding inductive loads such as air conditioners, well pumps, compressors, power converters, and power tools.
VE.Bus for Scalable Power Systems
- The VE.Bus communication port allows interconnecting up to 6 inverters in parallel for multiplied single-phase output or configuring three units for balanced 3-phase (400V) operation, easily accommodating future power expansion.
Intuitive Configuration and Remote Access
- Quick on-site setup is available via built-in DIP switches (battery voltage, frequency 50/60 Hz, search mode). In-depth configuration can be done via VEConfigure or VictronConnect (using the MK3-USB interface or VE.Bus Smart Dongle via Bluetooth). Pairing with a Cerbo GX or Ekrano GX unlocks free access to the VRM (Victron Remote Management) portal from anywhere in the world.
