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

ACCEPTANCEBULK FLOAT

VOLTAGE

• BULK:

Replaces 70-80% of the battery’s capacity at fastest possible rate

Voltage (V) • ACCEPTANCE:

Replenishes remaining 20-30% of battery capacity

• FLOAT:

Charger voltage is held constant. Replaces battery self-discharge 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

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

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 • 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
