Victron Energy Quattro 12V 5kVA 120V Inverter 220A Charger, Residential and Mobile Low Frequency Inverter

About the Victron Quattro 12/5000/220-100/100 120V VE.Bus

The Victron Quattro 5kVA is a transformer-based inverter-charger and transfer switch with grid interactive capability. It is ideal for heavy power needs like portable power stations, boats and yachts, grid-tied homes, off-grid cabins, and recreational vehicles.

Whether the installation is in a house, boat, or RV, Victron’s dedication to quality is evident in the materials used and in the ever-growing list of features and firmware updates.

Built-In Transfer Switch

The transfer switch features two isolated AC inputs and two AC outputs. The unit automatically switches between grid or shore power, generator, and inverter, based on which source is available. Both AC inputs are monitored for power loss, and the transfer switch reacts quickly so devices like computers and network equipment remain powered at all times.

Programmable Inverter Outputs and Charging

AC-Out one is for critical loads that should remain running at all times. By default, AC-Out two turns on when AC input is available, but can be reprogrammed to turn on and off loads at opportune times.

This inverter charges batteries up to 220Adc from AC inputs such as shore power or generators, and it can utilize the battery’s stored energy to power loads up to 5,000VA (4,000W) continuously, like a fully functioning kitchen or an EV charger.

PowerAssist and PowerControl

The inverter provides a pure sine wave output and 10kW peak capacity because of the low-frequency topology. For larger loads, the PowerAssist and PowerControl functions adjust charge current, and supplement incoming AC power with inverted power. They mitigate the chances of overloading an incoming AC connection.

When incoming power is more than the loads consume, PowerAssist automatically diverts extra AC power to battery charging.

Dynamic Neutral-Ground Bonding

In any system with multiple AC inputs, it’s crucial to prevent multiple connections between neutral and ground. To address this, the Quattro features a dynamic neutral-ground bonding relay that automatically connects the AC neutral output terminal to ground while operating in inverter mode and releasing this bond when powering loads from an external source. This design ensures that two neutral-to-ground connections do not occur simultaneously, preventing electrical shock hazards and tripping GFCIs.

Three Programmable Relays

Multiple programmable control outputs can be utilized to trigger external equipment and accessories such as auto-starting a generator (2-wire signal), turning on fans, diversion loads, or lights. Three relays (NO/NC) and an external ground relay connection are available. An input is also available to remotely turn on or shut down the inverter.

Power Connections

Two pairs of M8 battery connection terminals are provided to connect DC power from a battery bank. Use two sets of pre-crimped 2/0 AWG inverter power cables with 5/16″ ring terminals for this connection.  The AC input and output connections are M6 (~1/4″) brass studs for increased conductivity.  Use a set of mechanical lugs to transition from the stud to standard wire.

Programming the Inverter

Programming the inverter is accomplished by connecting a MK3-USB dongle to a computer. VictronConnect is used for basic programming and monitoring, or VEConfig for configuring advanced functions such as Aux relay output, grid-tie functionality, and more. Fine tune and monitor the system by adding a Cerbo-GX to connect the system to Victron’s Remote Monitoring (VRM) platform.

Inverters purchased from Current Connected are powered on and pre-programed prior to shipping. Additionally, our support team is able to assist with programming modifications and updates to systems connected via VRM.
