Product Details

The Victron MultiPlus 12/800/35-16 230V VE.Bus combines a true sine wave inverter and a sophisticated battery charger in a single compact unit. With a continuous output of 800VA and a 35A adaptive charging capacity, it ensures reliable power for sensitive electronics and efficient battery maintenance.

  • Max constant power 800VA off grid.
  • Use up to 3000VA on shore power.
  • Pure sine wave inverter & battery charger in one.
  • Charge your leisure batteries at 35A on shore power.
  • For 12V systems.

Key Features:

True Sine Wave Inverter:
The MultiPlus features a pure sine wave inverter, ensuring that the 12V DC power from leisure batteries is precisely converted to a clean 230V AC waveform.
Pure sine wave inverters are crucial for powering sensitive electronics, preventing potential damage or malfunctions that may occur with modified sine wave inverters.

Uninterrupted AC Power (UPS Function):
In the event of a grid failure, or when shore or generator power is disconnected, the MultiPlus activates automatically, taking over the supply to connected loads.
The transition occurs in less than 20 milliseconds, ensuring that computers and electronic equipment continue to operate without disruption.

Dual Power Source Handling:
When connected to shore power hookup, the MultiPlus powers mains appliances directly from the hookup while recharging leisure batteries.
Upon disconnection from the hookup, the MultiPlus seamlessly switches to powering mains appliances from leisure batteries, eliminating the need for manual intervention.
Charging Capability:

The 12/800/35 model allows charging of leisure batteries with a current of up to 35A, providing efficient and timely recharging.

Remote Monitoring and Control:
While lacking built-in Bluetooth or smart connectivity, the MultiPlus can be paired with the VE.Bus smart dongle.
Allows monitoring of inverter performance and settings via the VictronConnect app, enabling the configuration of alarms and cut-offs for low and high voltages.

Versatile Application:
Suitable for various off-grid electrical system applications, including campervans, motorhomes, RVs, and boats.
Ideal for systems where the total wattage of mains power appliances is 800VA or less.

Advanced Control Options:
Comprehensive monitoring and control capabilities through the free VRM app and VRM portal website.
Accessible locally or remotely via the internet from various devices, offering a high level of control over system parameters.
