3. Xantrex 458/(Combi 10) Inverter Charger
Charger – 3 stage temperature controlled
Bulk charge
Constant 100 amps DC charging current (50 amps)
Most of the energy is restored to the battery
Takes 21 amps AC to develop this charge current (11 amps)
Acceptance charge for wet cell batteries
Begins when voltage reaches (Cool)
90 deg = 14.0 (Warm)
50 deg = 14.8
Continues to apply constant voltage until
Charge Current decreases to 15 amps (5 amps)
One hour timer expires
Float charge for wet cell batteries
Maintains voltage of deg (Cool)
90 deg – 13.1 (Warm)
50 deg = 13.9

4. 458 Multi-Stage Charging BULK:
Replaces 70-80% of the battery’s capacity at fastest possible rate

5. Basic Remote Control
Can be used with Freedom 458 or Combi Inverters

6. Cannot be used with Freedom 458 Inverters
Combi Remote Control
Cannot be used with Freedom 458 Inverters

7. Reading the Remote - Charging
AC IN - will be lit.
DC AMPS - Drops following the charge cycle.
DC VOLTS - Follows the charge cycle
BATTERY STATE - Indicates stage of charge cycle
Left = Bulk, Middle = Acceptance, Right = Float

8. Reading the Remote - Inverting
AC IN - will NOT be lit.
DC AMPS - Varies with load demand.
DC VOLTS - Drops as battery is consumed
BATTERY STATE - Indicates Approximate Status of batteries.
Left = Recharge Needed, Middle = OK, Right = Full

9. Remote Control Functions
Equalizing Charge –intentional overcharging
Removes sulfate from battery plates
Brings each cell to same voltage and specific gravity
Mixes electrolyte
Wet Cell ONLY
Start with full charge and proper water level
Use Disconnect switch to isolate loads to prevent damage due to high voltage
16.3 v, variable based on temperature
Timed 8 hour cycle

10. Power Sharing Your Charger is an AC load Purpose Benefits
Uses more power than TV or Microwave
Charging power consumption is variable
Purpose
Sets the maximum limit of power consumption
Benefits
Automatically reduces charger’s consumption
Allows other AC loads on inverter circuit to run
Prevents tripping & overloading of shorepower breaker

11. Using the Remote - Power Sharing
Check setting every time you hook up
Set to size of your shorepower connection
Default is 30 amps
If breaker trips, reduce setting
Reducing power sharing reduces charger output
But, increases time needed to complete charging

12. Battery Control Center
Location
In the Electrical Bay
Purpose
Disconnect chassis and coach batteries from their loads
Control ignition switched loads
Controls paralleling of chassis and coach batteries for Charging and Auxiliary Starting
Protects various circuits with fuses and breakers
