- Extreme endurance (temperature range -40…+65°C) – the device is designed for uninterrupted operation under the harshest climatic conditions. It is excellent for outdoor installation in thermal enclosures, unheated rooms, attics, as well as in the utility cabins of special vehicles and marine vessels.
- Full compatibility with any generator types – the inverter works flawlessly in tandem with gasoline, diesel, inverter, and gas power plants. Flexible configuration allows automatic management of dry contacts (generator start/stop) based on the load level or battery state of charge (SoC).
- Wide range of control options — detailed monitoring, calibration, and software updates are available locally via PC or remotely via the Internet.
- Integration into the VRM ecosystem - a free cloud portal for complete remote control of your power system from anywhere in the world. It allows setting up PUSH notifications for any system events (grid failure, critical battery discharge, generator start) and process automation.
Technological Features
1. Two Independent AC Outputs
The first output is uninterruptible (main): it instantly takes over the power supply of critical loads during public grid failures. The second output is auxiliary: active only when external power (grid or generator) is available, protecting the battery bank from rapid discharge by non-essential consumers (boilers, irrigation systems, electric stoves).
2. PowerControl – Intelligent Protection of the External Grid Against Overload
You can set a strict current limit for a generator or a weak shore power line. The inverter will take this limitation into account and distribute energy: primarily to power the connected loads, and the remaining part to safely charge the batteries, preventing input circuit breakers from tripping.
3. PowerAssist – Power Boosting Function at Peak Loads
If the grid or generator capacity is insufficient to start heavy equipment, the MultiPlus will automatically add the missing energy from the batteries. Once the load decreases, the surplus power is again directed toward charging the batteries.
4. Full Support for Solar Generation
MultiPlus integrates perfectly into hybrid and off-grid systems with Victron solar MPPT charge controllers or third-party grid-tied PV inverters. The device operates in self-consumption, backup (UPS), and completely off-grid modes.
5. Remote Monitoring Worldwide
When connecting system controllers (Cerbo GX, Ekrano GX) or using the VE.Bus Smart Dongle via Bluetooth, you gain total control over the power station directly from your smartphone or via a web browser.
6. Remote and Local System Configuration
Using the MK3-USB interface for PC or the VRM cloud portal, engineers can remotely modify any inverter parameters: charging profiles, current limits, programmable relay logic, and protection configurations.
7. Power Supply System Scaling
Parallel and three-phase connection technology allows combining up to 6 devices in a single phase or building powerful three-phase clusters. This is the optimal choice for large private residences, production facilities, and commercial enterprises.
