My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.

Detailed Description

The NEW GENERATION Freedom SW series represents highly sophisticated and advanced inverter/chargers available in 3000 W with 150 A charger and 2000 W with 100 A charger models. The second generation 2000 watt model has been completely redesigned to include many of the same great features found in its high power counterpart. A key feature enhancement is ‘Generator Support Mode’ which enables the Freedom SW to supplement a generatorą when AC loads exceed the generator’s capacity.

Protection Features

  • Battery over-voltage and under-voltage protection
  • Over-temperature shutdown
  • Automatic overload protection
  • Short-circuit protection
  • Integrated, resettable AC breakers

The new generation models also feature 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 are approved to UL458 with marine supplement, CSA, ABYC and FCC, Class B requirements.

Parallel and Series Stacking

  • Parallel stacking enables the Freedom SW inverter/chargers to double the AC output in inverter mode
  • Series stacking enables the Freedom SW inverter/chargers to generate 120/240 V split phase output


Designed for a variety of mobile applications such as commercial, emergency and recreational vehicles, marine vessels, construction and military equipment.
