The 45 amp Progressive Dynamics INTELI-POWER 9245C is a state-of-the-art electronic power converter and battery charger. It converters 120 VAC power to 12 VDC power for all your 12 VDC lights and appliances. And unlike old fashioned converters, it does a superb job charging and properly maintaining your RV's battery.
Unlike earlier generation 9100 Series converters, 9200 Series converters have the Charge Wizard charging module built in so you don't need to buy any add-on accessories for efficient battery charging.
The Charge Wizard is a microprocessor-controlled device integrated inside the converter housing. It constantly monitors your RV battery, and then automatically adjusts the converter output voltage based on its charge status. This voltage variation is essential for fast recharging and property battery maintenance. For more information, click on the Field Notes tab above.
The Charge Wizard is a microprocessor-controlled device built in to Progressive Dynamics 9200 Series Inteli-Power Converters. It constantly monitors the RV battery, then automatically adjusts the converter output voltage based on the battery's charge status. The Charge Wizard has four (4) operating Modes (BOOST, NORMAL, STORAGE AND DESULFATION). Each Mode is automatically selected by the microprocessor and ensures a fast yet safe recharge for your RV battery.
Other converters run at a steady 13.6 VDC which is just what you need to power the 12-volt systems in your trailer. The problem is, 13.6 volts isn't the most efficient way to recharge a low battery...and it isn't the optimum way to store a battery. The 9200's Charge Wizard makes the converter an intelligent battery charger that will safely and rapidly recharge a discharged battery and then maintain it properly.
It does this by reading your batteries current voltage level. If your battery is depleted below 11.9V, the converter selects the Boost Mode (14.4V) of operation to rapidly charge your battery most of the way. Once the battery reaches 90% of full charge, 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 non-use of the 12-volt RV electrical systems. The lower charging voltage in the Storage Mode 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 charging voltage up to 14.4 volts for 15 minutes. This increased voltage mixes up the battery electrolyte and prevents battery stratification and the resulting problems of battery sulfation.
The chart below shows how the 9200's Charge Wizard moves from one mode to the next over time.
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 55 amp Inteli-Power converter set to three different output voltages to recharge a 125 AH (Amp Hour) battery after it was fully discharged to 10.5-volts.
As you can see the Charge Wizard's ability to increase the voltage of the 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, prevents 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.

NOTE: All battery chargers must be modified to work properly with true Gel Batteries. Gel Batteries prefer slightly lower voltages. If you plan to use your Inteli-Power with a Gel Battery, please contact us for details. AGM and all other types of lead acid batteries do not require this modification. Optima batteries are AGM batteries and work with these chargers with no modifications. If in doubt, please contact us for more information.
