Designed for whole-home backup, off-grid homes, and large RV or tiny home systems on a 48V bank. It also suits setups where a large kitchen or an EV charger needs to run from the inverter.
About the Victron Quattro 48V 10kVA Inverter/Charger The Victron Quattro 10kVA is a transformer-based UL certified inverter-charger and transfer switch with grid interactive capability. It is ideal for heavy power needs like portable power stations, grid-tied homes, off-grid cabins, and recreational vehicles. UL 1741 Certified This unit is certified to UL 1741 standards for grid-interactive systems. Whether the installation is in a house, tiny home, or RV, Victron’s dedication to quality is evident in the materials used and in the ever-growing list of features and firmware updates. Dual AC Inputs and Outputs 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. 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. 140A Battery Charger This inverter charges batteries up to 140Adc from AC inputs such as shore power or generators, and it can utilize the battery’s stored energy to power loads up to 10,000VA (8,000W) continuously, like a fully functioning kitchen or an EV charger. PowerAssist and PowerControl The inverter provides a pure sine wave output and 20kW peak capacity because of the low-frequency topology. For larger loads, the PowerAssist and PowerControl functions adjust charge current, and additional 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 Relay 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. 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 pre-crimped 4/0 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. Setup and Commissioning 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. Alternative energy solutions can be complicated.
