VICTRON MultiPlus II 5kVA (4kW) 48V Off-grid Hybrid Inverter Charger The 48/5000/70-50 MultiPlus-II intelligently combines the functions of a powerful 5000VA 48V pure sine wave inverter, a sophisticated 70A battery charger which features adaptive charge technology, and a high speed 50A AC transfer switch in one single unit. This makes the MultiPlus-II ideal for applications with limited space, and allows you to have a more compact and easy-to-troubleshoot system, especially since using the MultiPlus-II will require less cables compared to using separate units (i.e., separate inverter, battery charger, and AC transfer switch). Ideal for off-grid systems and backup installations, it suits remote cabins, mobile setups, garden offices, and energy-conscious households. Its ability to operate without batteries under specific conditions offers additional flexibility. Installation available – contact us for a quote. Key features 5000VA 48V pure sine wave inverter: converts DC current into 230VAC mains electricity, to run various household appliances such as a TV, laptop, lighting, fans etc. Able to generate up to 4000W of continuous power with a strong peak power handling capability of 9000W (to start appliances with electric motors). This inverter is a pure sine wave type, which easily surpasses modified sine wave inverters in terms of efficiency and compatibility with a wider range of appliances. Solar energy: The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is compatible with both solar charger controllers and grid-tie inverters. Enhanced flexibility: Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/5000/70-50 units, for example, will provide 24 kW / 30 kVA output power with 420 Amps charging capacity. Adaptive 70A 4-stage smart battery charger (bulk - absorption - float - storage): designed to enable safe and efficient unattended charging of a 48V battery. The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries, and the adaptive function automatically adapts the charging process to battery use. Uninterruptible power supply (UPS): This inverter/charger features a high-speed 50A AC transfer switch. This means that in the event of a grid failure, or shore or generator power being disconnected, the inverter within the MultiPlus-II is automatically activated and takes over supply to the connected loads. This happens so fast (less than 20 milliseconds) that sensitive loads (such as computers and other electronic devices) will continue to operate without disruption, eliminating the risk of losing data. Additional intelligent functions Programmable relay: The MultiPlus-II is equipped with a programmable relay which can be programmed for all kinds of applications, such as providing a start/stop signal to a generator. By default, the programmable relay is set as an alarm relay; i.e., the relay will de-energise in the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the input almost too high, battery voltage almost too low). Inbuilt safety protection: The MultiPlus-II offers complete protection against potential hazards such as output short circuit, overload, battery overvoltage & undervoltage, overheating, 230 VAC on inverter output (e.g., from another AC source), and input voltage ripple that is too high. The Storage mode: The Storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the Storage mode float voltage is reduced to minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to “equalise” the battery. This feature prevents stratification of the electrolyte and sulphation, 2 major causes of early battery failure. Temperature compensation: The temperature sensor (supplied with the product) serves to reduce charging voltage when battery temperature rises. This is particularly important for maintenance-free batteries, which could otherwise dry out by overcharging. Remote monitoring and control: When coupled with a GX device (e.g., Cerbo GX) you can monitor and control your MultiPlus-II and your system locally (via the local LAN/Wi-Fi network) or remotely via the internet from anywhere in the world, using the free VRM app or the free VRM portal website. Access can be from a phone, tablet, laptop, or PC for multiple operating systems.
