BATTERY CHARGE PROFILES

BATTERY CHARGE PROFILES

Please see attached documentation for Xantrex Freedom XC Pro and Progressive Dynamics for complete information on your charge system.
Below information for quick reference only and we do recommend that you read the manual for your charger before making any assumptions or changes to the system.

XANTREX INVERTER/CHARGER PROFILE

THE FREEDOM XC CHARGER CAN BE PROGRAMMED WITH DIFFERENT SETTINGS REGARDING THE CHARGE AMOUNT AND THE INTERMAL POWER MANAGEMENT THAT SHUTS OFF CHARGE TO THE BATTERIES WHEN CERTAIN HEAVY LOADS ARE IN USE. KEEP IN MIND THAT THIS WILL AFFECT HOW QUICKLY YOUR BATTERIES ARE RECHARGED.


  1. BULK CHARGE - first stage of charging process which provides batteries with a controlled, constant current.
  2. ABSORPTION - second stage that provides batteries with a constant voltage and the current falls gradually as the amp hours are returned to the batteries.
    1. Absorption mode has a Max default time limit of 6 hours. If there are DC loads on the batteries, the charger's current may never decrease to a level to initiate the next stage of charging. In this case, the charger would stay in absorption until the Absorb time setting is reached.

  3. FLOAT - maintains batteries slightly above the self discharge voltage rate. *Self Discharge rates vary by battery type. 

  4. EQUALIZATION - controlled overcharging of batteries to counter cell charge imbalance and capacity-robbing electrolyte stratification. Equalization is not used for AGM or Lithium batteries.
  5. NO CHARGE - not charging

PROGRESSIVE DYNAMICS SMART CHARGE PROFILE


  1. BOOST MODE - The charger outputs 14.4 volts into the battery bank to bring the batteries up to charge as quickly as possible. This does not mean that your battery bank has 14.4v for use but rather 14.4 volts are being sent into the batteries. If you look at the bottom of the chart it shows that boost mode can take 4 hours before the batteries reach about 90% capacity,
  2. NORMAL MODE - Charger drops to 13.6v safe charge to slowly bring the batteries up to full charge. Again, take a look at the bottom of the chart showing that it can take up to another 28 hours to reach 100% full charge.
  3. STORAGE MODE - Voltage is dropped lower to keep the batteries from gassing and/or boiling over.
  4. EQUALIZE MODE - This is used to equalize the batteries and occurs for only 15 minutes every 21 hours.
