After the great blackout of 28 April 2025, millions of homes in Spain were left without power. Victron Energy's MultiPlus range is the professional solution to prevent this from happening again. Inverter, charger and automatic switch in a single unit.
On 28 April 2025, Spain and Portugal suffered an unprecedented massive blackout. In just 5 seconds, the electricity grid lost 15 gigawatts of power, automatically disconnecting from the European system. Airports, hospitals, trains and millions of homes were left in the dark for hours.
This event made clear what many already sensed: dependence on the 100% from the mains is a real risk. And it's not just massive blackouts - local outages, storms, network overloads or system failures happen more often than we think.
The question is no longer “if” it will happen again, but “when”. Will you be ready?
Millions of families affected for hours without electricity
Hospitals, transport and communications collapsed.
The need for decentralised back-up systems became evident.
The Victron MultiPlus is much more than an inverter. It is a 3 in 1 which integrates a pure wave inverter, intelligent battery charger and automatic transfer switch (UPS) in a single compact and robust device.
In the event of a power failure, the MultiPlus detects the drop in the power supply. less than 20 milliseconds and automatically switches to batteries, keeping your appliances and devices running without interruption.
Power any mains-quality electrical appliance (230V / 50Hz)
Optimal battery charging with adaptive 3-stage technology
Automatic switch to batteries in less than 20ms. Your equipment does not shut down
Monitor and control your system from anywhere with the VRM app
Your home keeps running when the grid goes down. The MultiPlus switches to batteries in less than 20 milliseconds fully automatically. No interruptions, no worries. Fridge, lights, router, alarm... everything remains operational.
Combined with solar panels and lithium batteries, the MultiPlus-II allows you to generate, store and consume your own energy. You reduce your dependence on the grid and take control of your electricity supply with an ESS system.
With the ESS function of the MultiPlus-II, you can store solar surplus during the day and consume it at night, avoiding buying expensive energy at peak times. The savings can exceed 60-70% on your annual electricity bill.
Start with one MultiPlus and expand as needed. Up to 6 units can be configured in parallel or 3-phase. Compatible with Pylontech, BYD, Pytes and many more batteries.
