MultiPlus-II 24/3000/70-32 GX — an advanced solution for off-grid and hybrid power systems that combines a 3000 VA (2400 W) inverter, a charger rated at 24 V 70 A, an automatic transfer switch (32 A), and a built-in GX controller with a display, Ethernet, and WiFi.
Ideal for complex facilities requiring remote monitoring, integration with solar inverters, backup for critical loads, and support for ESS systems.
Key advantages of the MultiPlus-II GX inverter
Most of the key parameters listed below outperform competing models from European manufacturers and significantly outperform budget Asian solutions.
-
Rated power: 3000 VA / 2400 W, peak — 5500 W.
-
Pure 230 V sine wave — for stable operation of all electrical appliances.
-
Maximum efficiency up to 94% — efficient energy conversion.
-
Standby power consumption: 3 to 13 W.
-
24V DC voltage range (19–33 V) — optimized for LiFePO₄ batteries, adjustable for all known 24V battery types!
-
Powerful 24V 70A charger with temperature compensation.
-
Operating temperature range: –40…+65°C — for harsh conditions, including use in vehicles, unheated rooms, and outdoor cabinets.
-
Perfect compatibility with generators — gasoline, diesel, inverter, and gas. Supports fine-tuning via VE.Configure and VRM.
-
Integrated GX device — WiFi, Ethernet, display, USB, VE.Direct, BMS-Can — the device supports out-of-the-box connection of all possible Victron Energy accessories and synchronized operation with most manufacturers of lithium iron phosphate (LiFePO4) batteries with BMS.
-
Remote monitoring via the VRM portal and the VictronConnect App.
-
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 start or stop of the generator, 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, preserving 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 24/3000/70-32 GX apart from other manufacturers.
The GX model – enhanced controllability
- The MultiPlus-II GX features a built-in controller with a display and WiFi, allowing full access to all device parameters without external add-on modules.
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 power section durability.
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.
Support for grid inverters and MPPT
- Operates as part of flexible ESS systems, supports PV inverters and MPPT controllers with priority given to self-consumption or backup power.
Built-in monitoring and WiFi
- Data from the battery, charger, and inverter is available on the LCD display or via WiFi—from a phone, tablet, or PC.

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 grid outages.
-
Flexible charge/discharge logic – adaptation to tariffs, timers, and generators.
-
Use of grid-tied inverters – a full-fledged hybrid solar station with Fronius, Solis, SMA, and other grid-tied inverters.
-
Full visualization in VRM – analytics, event log, email, and push notifications to phones.
The goal of an 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 — the key to safety
The MultiPlus-II 24/3000/70-32 GX features a BMS-Can interface for connecting to “smart” lithium batteries with CAN bus support.
This ensures:
- accurate measurement of SOC (state of charge)
- prevent overcharging or deep discharge, which damages the battery
- automatically limit the current or shut off 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 warranty coverage throughout the battery’s 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 move.
- 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, connection of LiFePO4 batteries such as Pylontech and others.
-
BMS-Can – Connection to lithium batteries with a CAN bus, MPPT controllers, and other accessories.
-
VE.Direct – Connection to BMV/SmartShunt, third-party displays, and additional MPPT controllers.
-
USB / Ethernet – Connection to a PC, network, or VRM
-
VE.Bus Smart Dongle – Bluetooth monitoring, transmission of battery temperature and voltage.
-
