The Victron Quattro 3kVA allows for supplementing generators or grid power by utilizing the battery bank, allowing for a constant flow of power. This inverter comes with 2 independent AC inputs, allowing for multiple AC sources, such as grid power and/or a generator. The Quattro can automatically connect to the active source, meaning there is no need to monitor or manage what sources are being used. In the event of a grid failure or shore/generator power disconnection, the Quattro takes over in less than 20 milliseconds. 

The Quattro also features a secondary output, for loads that you don’t want to discharge the battery, as it is only available when AC power is available on the input. These Victron Quattro 3kVAs can be paralleled up to 6 times and are capable of both split-phase and three-phase operation. When paired with a GX device, this inverter can be remotely monitored and adjusted through a connected VRM (Victron Remote Monitoring).
