Victron MultiPlus-II 48/10000/140-100 230V Inverter/Charger

The Victron MultiPlus-II 48/10000/140-100 230V is a high‑performance inverter/charger that combines powerful 10,000 VA true sine wave output with a 48 V, 140 A smart battery charger in one compact unit, making it ideal for modern home energy storage and demanding professional installations.

Designed for use in advanced Energy Storage Systems (ESS), off‑grid power setups and backup systems, it offers intelligent PowerAssist technology, fast automatic transfer and full integration with solar PV, generators and the grid for reliable, uninterrupted power.

Key Features

• 10,000 VA inverter power (approx. 8,000 W continuous) with pure sine wave output for running sensitive electronics, pumps, tools and household appliances safely and efficiently.
  
• Integrated 48 V / 140 A battery charger with adaptive multi‑stage charging for fast, safe charging of lead‑acid or lithium batteries, helping extend battery life and performance.
  
• PowerControl and PowerAssist functions allow you to set a maximum current from the grid or generator, then automatically boost limited supply with battery power to prevent overloads and nuisance tripping.
  
• Built‑in anti‑islanding and wide range of international grid approvals make it suitable for ESS applications and grid‑connected solar PV systems, as well as fully off‑grid installations.
  
• High‑speed automatic transfer switch (UPS function) ensures a seamless changeover between mains and inverter power, keeping critical loads such as IT equipment, lighting and refrigeration running without interruption.
  
• External current transformer option (up to 32 A sensing) for optimising self‑consumption and fine‑tuning system behaviour in advanced hybrid systems.
  
• Scalable design allows parallel and three‑phase operation, so multiple units can be combined for higher power or larger systems as your energy needs grow.
  
• Comprehensive monitoring and configuration via VE.Bus with MK3‑USB interface or GX devices, enabling local and remote system management and firmware updates.
  
• High efficiency (up to around 94%) and low standby consumption help maximise usable energy and reduce running costs over the lifetime of the system.
  
• Rugged enclosure with wall‑mount design, suitable for utility rooms, garages, plant rooms and professional off‑grid installations.
  

Why Buy

• This unit replaces separate inverter, charger and transfer switch hardware with one professionally engineered device, simplifying design, cabling and installation while reducing points of failure.
  
• Perfect for homeowners who want reliable backup power for fridges, pumps, lighting and home offices, as well as for installers building fully featured ESS or off‑grid systems for clients.
  
• PowerAssist technology helps you get the most from a smaller generator or limited grid connection, which can significantly cut installation and running costs compared with oversizing supply capacity.
  
• Victron’s extensive ecosystem of monitoring tools, accessories and firmware updates means your system can be fine‑tuned and expanded over time rather than replaced as requirements change.
  
• Proven Victron reliability, with robust protections and automatic safeguards, offers peace of mind for both domestic users and trade professionals specifying critical power systems.
  

Suitable For

• Residential energy storage systems with solar PV, providing day‑to‑day self‑consumption optimisation and blackout protection.
  
• Off‑grid homes, remote cabins, farm buildings and holiday properties requiring dependable 230 V power from batteries and renewable sources.
  
• Professional installations such as small commercial sites, workshops, telecoms systems and utility rooms where robust, scalable power is essential.
  
• Backup and UPS applications for IT equipment, home offices, security systems and other mission‑critical loads.
  
• Marine, vehicle and specialist mobile power systems built on a 48 V battery platform and requiring EU‑voltage 230 V output.
