Victron Energy Quattro-II 48/5000/70-50/50 230V

The Quattro-II is a multifunctional power inverter similar to the MultiPlus-II, combining an inverter and a charger into one unit. It can accept two AC inputs and automatically connect to the active source. Key features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, and options for three-phase, split-phase, and parallel operation. Available Quattro-II 12V and 24V inverter/chargers come in 3000W and 5000W models.

Two AC Inputs and Two AC Outputs
• Dual AC Sources: The Quattro-II can connect to two separate AC sources (like shore power and a generator) and will automatically switch to the active one.
• Main Output: The main output provides uninterrupted power. If the grid fails or shore/generator power is disconnected, the Quattro-II takes over in less than 20 milliseconds, keeping computers and electronics running without interruption.
• Secondary Output: This output is active only when AC power is available. It’s ideal for connecting loads that shouldn’t drain the battery, such as air conditioning or water heaters.

Unique PowerAssist Feature
• Overload Prevention: The Quattro-II prevents overloads from a limited AC source (like a generator or shore power). If there’s a risk of overload, it will reduce battery charging. If needed, it will also boost the output by using power from the battery.

Virtually Unlimited Power
• Parallel Operation: Up to 6 Quattro-II units can work together to increase power output. They can also operate in three-phase or split-phase configurations. Check the datasheets for models that support these features.

Remote Monitoring and Control
• GX Device Integration: When paired with a GX device (like Cerbo GX), you can monitor and control the Quattro-II locally or remotely via the internet using the free VRM app and portal.
• Access Anywhere: Use a phone, tablet, laptop, or PC to adjust settings, start a backup generator, and more from anywhere in the world.
