Charge Wizard is our
circuit built into all our PD9200 Series converters. The Charge
Wizard constantly monitors the RV battery voltage and then
selects one of three charging voltages and one of four operating
modes to properly re-charge or maintain the RV battery. The
addition of the Charge Wizard makes all our 9200 Series
converters an intelligent battery charger. It will safely and
rapidly recharge a discharged battery by automatically selecting the Boost
Mode (14.4V) to rapidly re-charge the battery to 90% of
full charge. Once the battery reaches 90%, the Charge Wizard automatically selects the
Normal Mode (13.6V) to safely complete the charge. The
Storage Mode (13.2V) is automatically selected after 30 hours
of no significant usage of the 12-volt RV electrical systems. The lower
charging voltage in the Storage
Mode of of operation reduces
battery gassing and water usage,
while maintaining the charge. Every 21 hours when the system is
operating in the Storage Mode, the Charge Wizard
will automatically switch to the Desulfation Mode of
operation. The Desulfation Mode increases the output
voltage up to 14.4 volts for 15 minutes. This increased voltage
mixes up the battery electrolyte to help prevent battery
stratification and the resulting problems of battery sulfation.

BATTERY RECHARGE CURVES
WITH CONVERTER OUTPUT VOLTAGE SET AT 14.4, 13.6 AND 13.2-VOLTS
The chart above shows
the amount of time it took a PD9155 (55-amp) converter set to three
different output voltages to recharge a 125 AH (Amp Hour) battery after
it was fully discharged to 10.5-volts.
(Boost Mode) – Returned the battery to 90% of full charge in
approximately 3-hours. The battery reached full charge in approximately
(Normal Mode) – Required 40-hours to return the battery to 90%
of full charge and 78-hours to reach full charge.
(Storage Mode) – Required 60-hours to return the battery to 90%
of full charge and 100-hours to reach full charge.
As you can see the
Charge Wizard's ability to increase the voltage of our converters from
the Normal Output Voltage of 13.6-volts to 14.4-volts in the Boost Mode,
will significantly reduce the time it takes to recharge your RV battery.
The lower voltage 13.2-volts Storage Mode, helps prevent battery gassing and
water loss allowing you to keep your RV plugged into 120 VAC power
during storage to maintain the battery at full charge.
