Quattro-II — inverter/charger with two inputs and ESS function
Country: Netherlands · Model: Quattro-II
The Quattro-II inverter/charger has 2 AC inputs, one for the grid and one for a generator, and comes as 24/5000/120-50, 48/5000/70-50 and other models. It is the new Quattro generation with support for energy storage systems (ESS), chosen for sites where a generator is permanently installed and works alongside the grid.

Description
Grid and generator land on separate terminals, and the unit selects the active input and moves the load between them on its own. When the grid fails the battery carries the load, and once the generator starts the inverter switches to the second input and charges the bank at the same time. In ESS mode the inverter charges and discharges the battery on commands from a system controller, for example storing daytime solar energy for the evening. PowerControl and PowerAssist limit the draw from a weak source and add battery power on top, so a small generator is not overloaded when a pump or compressor starts. In 24/5000/120-50 the figure 120 is the charge current in amps and 50 the transfer switch current, while the 48/5000/70-50 charges at up to 70 A. The Quattro-II goes onto farms, bases and country houses with a backup generator and solar generation.
How to choose
The second input only matters where a generator is permanently connected. Without a generator, a MultiPlus-II with one input and PowerAssist up to 100 A is simpler. Between models the bank decides, with the 24/5000/120-50 for 24 V batteries and the 48/5000/70-50 for 48 V, where DC-side currents are half as high. The previous Quattro generation at 3–15 kVA fits when one unit must deliver more than 5 kVA or offer 2 outputs, the main one switching without a break in < 20 ms.

FAQ
How many inputs does the Quattro-II have?
2 AC inputs, for grid and generator.
Does the Quattro-II support ESS mode?
Yes, ESS is supported along with PowerControl and PowerAssist, and a system controller runs battery charge and discharge.
Which Quattro-II models are available for 48 V?
For example the 48/5000/70-50, and for 24 V there is the 24/5000/120-50.
Do I need a transfer switch to connect a generator to the Quattro-II?
No, the generator lands on its own input and the inverter selects the source itself.
