How the <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong> <strong>Inverter</strong>/<strong>Charger</strong><br />
Works<br />
The <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong> is designed to:<br />
• invert,<br />
• charge, and<br />
• accept both split phase and dual input.<br />
With AC input available from the utility grid or a generator, power is passed<br />
through the <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong> <strong>Inverter</strong>/<strong>Charger</strong> to operate connected AC<br />
loads. The remaining AC power not used by loads is converted to DC<br />
power and used to charge batteries.<br />
If AC input power becomes disconnected, fails, or falls out of specification<br />
and is no longer qualified as good AC, a quick transfer takes place and the<br />
<strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong> begins converting DC power from the batteries into AC<br />
power, to continue to supply power to the AC loads.<br />
Inverting<br />
The <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong>’s inverting function produces 120 volts AC from<br />
your batteries at <strong>3000</strong> watts continuous with 6000 watts of surge power to<br />
start loads like pumps and refrigerators.<br />
Charging<br />
Introduction<br />
The <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong>’s charging function:<br />
• produces 150 amps to charge your batteries, and<br />
• equalizes flooded, lead acid batteries.<br />
Built-in Charge Formulas For the unit to perform at the highest level,<br />
the batteries must be charged correctly. The <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong> has<br />
optimized algorithms for flooded, gel, and AGM batteries.<br />
Battery Temperature Sensor Since battery temperature is a key factor<br />
in correct charging, the charging formula must be adjusted (automatically<br />
and in real time) according to the actual battery temperature to ensure that<br />
batteries are fully charged, but not overcharged. For this reason, <strong>Xantrex</strong>®<br />
has included a battery temperature sensor with your <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong> and<br />
has temperature compensated the charge formula.<br />
Manual Equalization Over a period of time, the cells in a flooded<br />
battery can develop uneven chemical states. This can result in a weak<br />
(undercharged) cell which, in turn, can reduce the overall capacity of the<br />
battery. To improve the life and performance of a non-sealed, flooded<br />
battery, the <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong>’s multi-stage charging cycle includes a<br />
manual equalize mode that can be used, if recommended by the battery<br />
manufacturer.<br />
Dead Battery Charging Another feature that the <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong><br />
includes is dead battery charging. The <strong>Freedom</strong> <strong>SW</strong> <strong>3000</strong>—unlike many<br />
chargers—has the ability to recharge batteries even if the battery voltage is<br />
very low, i.e., as low as 5 volts.<br />
