Charging The Battery Bank; Regular Loss Of Commercial Power - Wagan ProLine 2007-2 User Manual

10. When the voltage reading does not fall within this range, check the connections of
the wires to the terminals on the battery bank and the inverter to make sure they are
secure. Also check the voltage of the power source. Advance the Digital Display to the
Diagnostic Error Codes (green LEDs not lit). Look for code E03: Low Voltage Shutdown.
If this code is present, then check for loose connections of discharge batteries.
11. Turn off the inverter. The audible alarm may sound a short "chirp". This is also normal.
12. When you have confirmed that the appliance to be operated is turned off, plug the
appliance into one of the two AC outlets on the front panel of the inverter.
13. Turn the inverter on.
14. Turn the appliance on.
15. The Remote On/Off switch should be placed in a location convenient to the user.
Insert the cable plug into the front panel connector. The inverter's Front Panel On/Off
Switch must be On for the Remote Switch to operate. A lit LED indicator on the Remote
Switch indicates when DC power is applied to the inverter. Pressing the momentary
button controls On/Off operation of the inverter.
Note: If an extension cord is used from the inverter to the appliance, limit the extension
cord length to 50 feet or less. Make sure that the cord is properly rated to carry the
appliance load.

CHARGING THE BATTERY BANK

It is not the purpose of this Inverter User's Guide to provide detailed information regarding
battery charging systems. However, the user should try to augment any charging system with
either wind power or solar power. These can continue to operate during power outages and
they also reduce recharge time. If automatic AC powered battery chargers do not provide
enough charging current for a larger battery bank, it is permissible to have two automatic
battery chargers connected to the battery bank.

REGULAR LOSS OF COMMERCIAL POWER

If the inverter system is used during commercial power outages that occur daily, configure
the charger system to replace energy during the time that commercial power is available.
Replacement of battery energy always requires more than was taken from the battery
(typically 130 percent). In the example used earlier in this document, the AC load ran for 10
hours. If commercial power is available, there are approximately 14 hours left in the day to
do the recharging. The following is an example of what is necessary to recharge a battery
bank that has 1,650 AH of capacity (as in the example above) and has been discharged to
10.5 volts (discharged). The charger has to replace 2,145 AH (1650 x 1.3 AH) in 14 hours,
so the charger must charge at a rate of 153 amps for 14 hours. As this charge current is
distributed among the batteries in the battery bank, the current received by an individual
battery is within its charge rating. Be sure that the battery is well vented as the area will
likely have accumulations of an explosive mixture of hydrogen and oxygen. Follow all
recommendations for use that are contained in the battery charger manual.
