Buyer's Guide

What sets the Victron Quattro apart from the competition?

Three simple facts; Quality, Efficiency, Functionality


Victron dominates the competition in terms of reliability, largely because they are the only system not made in China.  Because of this, we cover Victron for 10 years by the Current Connected extended warranty.


The Victron Quattro 3000 is 94% efficient with only 24 watts of idle draw thanks to Victron’s revolutionary toroidal transformer design, which keeps the magnetic field confined within the circular core.  Meanwhile, competitors are exaggerating their specifications,  claiming “up to” 88% efficiency, and continually wasting over 60 watts at idle.  This is the result of using the cheapest transformer possible to shave costs.

Competing “transformerless” inverters claim higher efficiencies, but they fail the moment they are presented with the inrush of a motor load, such as air conditioners, vacuum cleaners, and air compressors.  They also have a much noisier output waveform, which can harm sensitive electronics.  The galvanically isolated output of Victron’s low frequency transformer design is as close to AC grid power reliability as you can get.


The Quattro lineup features Dual AC inputs so that you don’t need an additional transfer switch to select between Grid & Generator, further saving on additional system equipment.  For on-grid applications, the Quattro can be used in ESS [energy storage system] mode for grid-sellback.  Victron is the only inverter manufacturer to feature remote voltage sensing, so that the voltage drop caused by your battery cables is compensated.  Our engineering team is ready to help you implement the many extended features of the Quattro product line.
