Victron Energy Quattro 48/3000/35-50/50 VE.Bus 48VDC 120VAC 3000W Inverter 35A Charger

The Quattro 48/3000/35-50/50 is a reliable 48-Volt 3000-Watt pure sine wave inverter with an adaptive 35A battery charger and two 50A AC inputs. The inverter’s output is 120V AC.

Quattro and Multiplus inverters/chargers share many great features. One difference is that the Quattro has two independent AC inputs and a built-in transfer switch configurable with intelligent rules. An example of a dual AC source could be grid power and a generator, or two generators, diesel and gas.

Here is a table with all 48V Quattro inverter models:

Quattro inverters have two AC outputs. The main output features a 20-millisecond no-break transfer switch allowing computers and electronic equipment to operate without interruption in the event the grid or the generator disconnect. By default, the second AC output runs only when an AC input is available; it is intended for non-critical loads that should not discharge the batteries, for example, a water heater. However, the auxiliary AC output can be configured for many other scenarios.

240V Split Phase and 3-Phase Operation

Stack two Quattro inverters to build your 240V split phase system, or configure three inverters for a 3-phase system. You can have up to six inverters in parallel per phase, significantly increasing the system’s capacity. 

Robust and Configurable AC Charger

The main output of the Quattro inverters uses advanced adaptive charge software with a fine-tuned three-stage automatic charging; it has a fourth stage for long periods of float charging. 

The Quattro allows you to set a maximum input current (AC) from the generator or shore power; the charger will then prioritize the loads (AC output) and use the remaining energy to charge your batteries. 

Quattro inverters are also equipped with a PowerAssit feature that will take energy from the batteries to assist the generator when its capacity is not enough to run the loads during high demand (peak) periods; once the loads are back to normal, the charger will use the generators excess energy to recharge the batteries. 

Easy System Configuration

The Quattro will operate out of the box without any additional configuration. The factory settings can be modified using the inverter’s DIP switches. VE.Net can be used instead of the DIP switches and the VE.Bus software is available for more sophisticated settings and features.
