Stand-By Operation; Battery Charging - Holiday Navigator 2003 Owner's Manual

The inverter can be set-up for stand-by power operation. For example: If
AC input is discontinued to the motorhome, the inverter will automatically
provide AC power. When AC power resumes, the inverter will automatically
return to "stand-by" mode. Battery charging is not effected by stand-by
operation. When AC power resumes the inverter will automatically return to
Stand-by mode.
To Activate Stand-by Mode:
• Press the red ON/OFF button until the cursor indicates ON.
NOTE: Remember to disable stand-by operation when not in
use. House battery power may be accidentally consumed.
NOTE: In All Electric motorhomes, the inverter supplies the
power necessary to operate the refrigerator if shore power is not
available or not operating from the generator.
Whether hooked to shore power or operating from the generator, the
internal battery charger of the inverter will charge the house batteries. Battery
charging does not begin automatically when AC power is available. The
inverters must be turned on to begin battery charging. The time it takes to
charge the batteries to a full state of charge varies greatly. It can take several
hours or even days depending on the actual state of charge of the batteries and
DC power consumption.
The inverter uses a three stage charging cycle. The first stage is "bulk"
charge. The bulk charge will bring the DC voltage up high, initially between
14.2 and 14.6 Volts depending on ambient temperature. Voltage and current
control the bulk charge cycle. The length of time the inverter is in the bulk
charge cycle will vary with the state of charge of the batteries. The second
stage is the "absorb" cycle. The battery voltages in the absorb cycle are the
same as the bulk charge cycle between 14.2 and 14.6 Volts. The length of the
absorb cycle is a timed event determined by the menu item Set Absorption
Time under the menu heading number 9, Inverter Setup. The final charging
stage is the "float" charge cycle. Approximately 80% of the charging cycle is
completed by this time. The float charge voltage is generally around 13.3 to
13.7 Volts. The last 20% of the charge cycle requires the most amount of time.
To Begin Battery Charging:
• Hook to shore power or start the generator.
• Press the red button on the inverter remote until the cursor
indicates either CHG or On.
