The MultiPlus-II 24/5000/120-50 hybrid inverter — is a powerful and intelligent inverter-charger that combines a 5000 VA (4000 W) inverter, a 24 V 120 A charger, a 50 A automatic transfer switch, and advanced functionality for working with modern energy storage systems (ESS).
This model is the ideal choice for solar, backup, and off-grid solutions where high reliability, scalability, and flexible energy flow management are required.
Key advantages of the MultiPlus-II inverter
Most of the key parameters listed below outperform competing models from European manufacturers and significantly outperform budget Asian solutions.
-
Power: rated — 5000 VA / 4000 W, peak — 9000 W.
-
True sine wave 230 V ±2% — for uninterrupted operation of sensitive devices.
-
Maximum efficiency up to 96% — efficient operation with minimal losses.
-
Low power consumption in standby mode — only 3–18 W depending on the mode (AES/Search).
-
Wide voltage range (19–33 V) — fully compatible with LiFePO₄ batteries, easily configurable for all available 24 V battery types.
-
Temperature resistance: from –40°C to +65°C, active cooling, fan operates only when necessary. The inverter can operate reliably in vehicles with large temperature fluctuations, as well as be installed in outdoor cabinets or in unheated rooms, attics, and other locations with harsh conditions.
-
Compatibility with all types of generators — gasoline, diesel, inverter, and gas. The inverter has a wide range of settings that ensure compatibility with generators and allows for quick and easy configuration. It can control the generator’s status (start/stop) based on the battery charge.
-
Two independent AC outputs — for critical and non-critical loads, a crucial option when using the MultiPlus-II 24/5000/120-50 inverter as part of a solar power plant.
-
Additional options:
-
Interface MK3-USB — PC configuration.
-
VE.Bus Smart Dongle – Bluetooth monitoring.
-
BMV-712 / SmartShunt – Battery status monitoring.
-
Cerbo GX / Ekrano GX – full control and integration with VRM.
-
-
Modern VRM software – allows you to keep the system under full control and receive pre-configured notifications about system changes (power outage, battery discharge to a certain percentage, automatic generator start or stop, and any other events can be used as triggers for push notifications and process automation).
Technical Features
Separation of Critical and Non-Critical Loads
- The first output is continuous. The second is available only when an external source is present. This allows for efficient energy distribution while conserving the battery charge. Contact the managers at Total-Energo LLC to learn more about the configuration options for the two outputs and how this sets the MultiPlus-II 24/5000/120-50 apart from other manufacturers.
The difference between the MultiPlus-II and the MultiPlus
- The MultiPlus-II supports an external current sensor up to 100 A for advanced PowerAssist/Control and finer tuning of the ESS system. Standard MultiPlus units have a higher overload capacity and greater durability of the power section.
Three-phase and parallel operation
- Up to 6 units in parallel or 3 per phase — ideal scalability for homes, businesses, or farms.
PowerControl / PowerAssist
-
PowerControl — limits consumption from the generator/grid.
-
PowerAssist — adds power from batteries during peak load moments.
Working with solar systems
- The MultiPlus-II easily integrates with MPPT controllers and grid-tied inverters, forming hybrid and off-grid systems.
Remote control and monitoring
With the Cerbo GX / VRM portal, you control everything:
-
Battery SOC
-
Load power supply
-
Charge, PV generation
-
Remote updates and configuration
Victron ESS (Energy Saving System) – next-level smart energy storage
Victron ESS allows you to maximize the efficiency of solar energy use:
-
Self-consumption priority – reducing dependence on the grid.
-
Automatic backup – powering critical loads during a grid outage.
-
Flexible charge/discharge logic – adaptation to tariffs, timers, and generators.
-
Use of grid-connected inverters – seamless integration with Fronius, Solis, SMA, etc.
-
Full visualization in VRM – analytics, event log, email notifications.
The goal of the ESS is to significantly reduce electricity costs and protect consumers from regular or emergency power outages. The ESS is optimized for the user’s specific electricity usage scenarios to achieve maximum independence and efficiency in solar energy utilization.
LiFePO₄ support with data exchange – safety and accuracy
The MultiPlus-II 24/5000/120-50 is fully compatible with lithium batteries, including LiFePO₄ with BMS via VE.Bus and/or VE.Can. Data exchange allows:
- accurately measure SOC (state of charge)
- prevent overcharging or deep discharge, which damages the battery
- automatically limit current or disconnect the load when critical battery parameters are reached
- synchronize the charging profile according to the battery manufacturer’s recommendations.
- log all warnings and critical events in the event log
- maintain the warranty throughout the maximum service life
This is critically important for the safety, service life, and stable operation of batteries in modern power systems.
Use Cases
- ESS for solar power stations – maximum utilization of self-generated power.
- Homes and cottages – with backup power, solar panels, and off-peak rates.
- Commercial, stores, service stations – stable power for critical equipment.
- Mobile workshops, motorhomes – full autonomy on the go.
- Yachts and boats – power for refrigerators, electronics, and pumps.
- Servers, cameras, security systems – uninterrupted power supply.
Communication and monitoring interfaces
-
VE.Bus – Parallel/three-phase operation, communication with Cerbo GX.
-
VE.Bus Smart Dongle – Bluetooth monitoring, transmission of battery temperature and voltage.
-
MK3-USB – Configuration via PC and VEConfigure.
-
I/O inputs/outputs – Programmable relay, generator control, or emergency shutdown.
-
GX devices (Cerbo GX) – Integration with the VRM portal, monitoring, control, and software updates.
The MultiPlus-II 24/5000/120-50 inverter features all modern ports for integration into any system, including smart homes, displaying data on chartplotters in boats, motorhome control panels, etc.
