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 14.4v @70deg (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 13.5v @70 deg (Cool)
• 90 deg – 13.1 (Warm)
• 50 deg = 13.9

at fastest possible
rate
• ACCEPTANCE:
Replenishes
remaining 20-30% of
battery capacity
• FLOAT:
Charger voltage is
held constant.
Replaces battery selfdischarge and
powers other DC
loads connected to
the battery

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
7
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

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

Power Sharing
• Your Charger is an AC load
• 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
10
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
11
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
