Xantrex Technology Inc., a subsidiary of Schneider Electric, has launched the second generation Freedom SW inverter/charger models.

The original series redefined the inverter/charger category and enjoyed great reception in 2010 with an entry level 2000 watt and feature-rich 3000 watt models. The second generation 2000 watt model has been redesigned to include many of the same features found in its high power counterpart. 

Both models now offer new parallel and series stacking features that were unavailable in the previous generation. Parallel and series stacking allows two units (either 2000 watt or 3000 watt) to work in synergy to provide up to twice the rated current and charging output, resulting in the ability to operate high power loads while charging large battery banks. Series stacking, for example, allows operation of 240 Vac applications, such as a dryer.

Another feature enhancement is Generator Support Mode which enables the Freedom SW to automatically supplement a generator when AC loads exceed the generator's capacity.

Some additional key features include an improved AC transfer/AC input detection time, providing the ability to transfer AC loads to batteries in less than 10 milliseconds when the incoming grid or generator power is lost. Connected loads are almost unable to feel the power transition due to this quick transfer time. Both models also offer full output in higher temperature range and feature efficient, power factor corrected charging. In addition, both are compatible with the optional system control panel and automatic generator start, and meet CSA, UL 458 with marine supplement, FCC Class B and ABYC requirements.
