Versatile inverter/charger that can adapt to growing system demands. Inverter/chargers are a great way to combine two key components of your boats electrical system into a single unit. The versatile Xantrex Freedon SW series not only joins a true sine wave inverter with an advanced multi-stage battery charger, it also has features that make expansion easier. With 3000W of continuous AC output, this inverter/charger is ideal for boats with large AC demands. The 150A battery charger will keep up with a large sized battery bank. If your needs change, the Freedom SW can be combined with other components to grow with the demand. The true sine inverterprovides AC power from your battery banks that matches that of grid supplied power. This clean power minimizes harmonic distortion and allows appliances and sensitive electronics to operate and function as designed—without the risk of damage. Ideal for use with variable speed motors and microprocessor controlled appliances and electronics Several features make the Freedom SW easier to use.A built in transfer switch simplifies returning to the dock by a seamlessly transitioning AC loads from the battery banks to shore power (grid) supplied power without a noticeable disruption in current. A generator support mode allows the inverter to step in to assist the generator when AC loads exceed the genset's capacity. An optional automatic generator start feature protects batteries by starting up the generator to charge the batteries while continuing to supply AC. With an optional remote ON/OFF switch, you can link the inverter to the ignition switch to prevent unwanted battery discharge when the alternator isnt providing power. Multi-stage chargingis the best way to restore a batterys charge and extend battery life. The Freedom SW is power factor corrected for maximum efficiency and uses a 3 stage charging system (bulk, absorption and float) plus a manual equalize feature to charge, flooded, AGM and Gel batteries. The equalize feature helps to retain maximum battery capacity by removing crystals that form on the plates. Using the optional system control panel, you will be able to program charging rates to match manufacturers specifications. The charger also compensates for battery temperature using the included sensor. Expansion is easierwith the help of Xantrex stacking abilities. Two
