Operating The Freedom SW 3000
Operating in Charger Mode
NOTES:
• Study and follow all of the battery manufacturer's specific precautions,
such as removing or not removing cell caps while charging, whether
equalization is acceptable for your battery, and recommended rates of
charge.
• For flooded non-sealed batteries, add distilled water in each cell until
battery acid reaches the level specified by the battery manufacturer.
This helps to purge excessive gas from cells. Do not overfill. For a
battery without removable cell caps, carefully follow manufacturer's
instructions.
To operate the Freedom SW 3000 in charger mode from the front
panel:
1. Connect AC input power.
The charger automatically starts up when qualified AC power is
connected if the charger is enabled, or the charger is disabled but the
Force Charge enable override is On. See “Force Charge” on page 23.
• The batteries are charged according to the two-stage or three-stage
formula you have selected on the SCP.
See “Battery Charging
Reference” on page 55 for more information on two-stage or three-
stage charging.
• You can interrupt the charge cycle any time you desire by disabling the
charger from the SCP.
• To maintain optimal performance in flooded batteries, an occasional
equalize cycle may be required. See “Operating in Equalization Mode”
on page 18.
• While the batteries are being charged, you can monitor which stage
they are in from the front panel of the Freedom SW 3000 or from the
SCP.
2. To operate the charger with the SCP, refer to “Configuration” on page
25.
Charger Operation with Battery Temperature
Sensor (BTS)
Since battery temperature is a key factor in correct charging, the charging
formula must be adjusted (automatically and in real time) according to the
actual battery temperature to ensure that batteries are fully charged, but not
overcharged. For this reason, Xantrex has included a BTS (see Figure 6)
with your Freedom SW 3000 Inverter/Charger and has temperature
compensated the charge formula.
The BTS continuously measures the temperature of the battery and adjusts
charger output for a more accurate, temperature-compensated charge.
EXPOSURE TO CHEMICALS AND GASES HAZARD
• Make sure the area around the battery is well ventilated.
• Make sure the voltage of the batteries matches the output voltage of
the inverter/charger.
Failure to follow these instructions can result in death or serious
injury.
