Victron MultiPlus-II 48/6500/100-50 Inverter Charger

The Victron MultiPlus-II 48/6500/100-50 is a sophisticated, all-in-one power hub designed to give you complete independence from the electrical grid. Whether you are looking to power a remote off-grid home, a large boat, or simply want to ensure your essential appliances never turn off during a power cut, this unit has the strength and intelligence to manage it all.

It combines a powerful 6,000-Watt inverter with a smart battery charger that looks after your batteries to make them last longer. It is the perfect fit for anyone who needs high-capacity, professional-grade power that is easy to live with every day.

Seamless Backup Power: If the grid fails, your lights and computers stay on without so much as a flicker, switching over in less than 20 milliseconds. Prevent Blown Fuses: Its clever PowerControl feature automatically limits the power it takes from a generator or shore supply to ensure you never overload the system. Extra Boost When Needed: When you need a bit more power for heavy appliances, PowerAssist pulls extra energy from your batteries to help out your generator or grid connection. Cheaper Energy Bills: This unit can be set up to prioritise solar energy or cheaper off-peak electricity, storing it in batteries to use when prices are higher. Highly compatible with popular battery brands: Victron, Pytes, Fogstar, etc. Built to Last: With a 5-year warranty and a robust steel enclosure, this is a long-term investment in your home’s energy security. Monitor from Anywhere: You can check how much power you are using or how much your solar panels are producing from your phone or laptop, anywhere in the world.

Product Details

The Victron MultiPlus-II 48/6500/100-50 Inverter Charger is a heavy-duty 48V inverter charger that provides a continuous 6,000 Watts of power, making it capable of running high-demand appliances like kettles, washing machines, or air conditioning units without effort. Because it is a 48V system, it is exceptionally efficient for larger installations where you need to move a lot of energy safely.

At its heart, this is a multifunctional device. It acts as a bridge between your batteries, your solar panels, and the grid or a generator. The unit features two separate AC outputs; the first is for your critical items like the fridge or internet router that must never lose power, while the second output can be used for non-essential items that should only run when external power is available, ensuring you don't accidentally drain your batteries.

One of the most impressive features for those using smaller generators is the PowerAssist technology. It allows the MultiPlus-II to "co-supply" power. For example, if your generator can only provide 2,000 Watts but your oven needs 3,000 Watts, the unit will seamlessly pull the missing 1,000 Watts from your batteries.

For those looking to save money on energy, the unit is fully compatible with Energy Storage Systems (ESS) . It can be programmed to use solar power first, then battery power, and only go to the grid when absolutely necessary. If you find your power needs grow in the future, the MultiPlus-II is ready for expansion. You can connect up to six units together in parallel to create a massive power supply for even the largest properties.
