Product Details

The Victron MultiPlus 48/800/9-16 is a versatile true sine wave inverter and advanced battery charger designed for off-grid applications. Combining efficiency and intelligence, it converts 48V DC power from leisure batteries to 230V AC power, enabling you to power domestic appliances up to 800VA when off-grid and up to 3000VA when connected to shore power. Here are the key features and details:

Key Features:

800VA True Sine Wave Inverter/Charger:
Powerful inverter with a true sine wave output ensures compatibility with a wide range of 230V appliances.
Sophisticated battery charger integrated into the system.

Seamless Power Source Switching:
Automatically switches between power sources without disruption.
When connected to shore power, appliances are powered directly from the hookup, and batteries recharge. In case of disconnection, the MultiPlus switches to powering appliances from batteries.

Charging Capabilities:
The 48/800/9 model allows for charging leisure batteries at a current of up to 9A.
Off-Grid Use Case:

Ideal for off-grid applications in campervans, motorhomes, RVs, and boats.
Suitable for users with mains power appliances totalling 800VA or less.

Pure Sine Wave Inverter:
Contains a pure sine wave inverter that precisely replicates the 230V AC waveform from household mains.
Ensures compatibility with all 230V appliances, safeguarding sensitive electronics.

Uninterrupted AC Power (UPS Function):
Activates automatically in less than 20 milliseconds during a grid failure, shore, or generator power disconnection.
Provides uninterrupted power supply, allowing computers and electronic equipment to continue operating seamlessly.

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.
Programmable alarms and cut-offs for low and high voltages can be set for added control.

VRM App and Portal Access:
Monitor and control the MultiPlus locally or remotely via the free VRM app and VRM portal website.
Accessible from various devices, including phones, tablets, laptops, and PCs.

Adaptable for Various Systems:
Can be integrated with the Color Control GX or Venus GX for advanced control features.
