The new PD9200 Series RV Converter/Chargers have our patented Charge Wizard built-in to provide you with the most advanced RV battery charging system on the market today. The Charge Wizard is a micro-processor controller that constantly monitors your RV battery voltage and then automatically determines which one of four modes of operation is best suited to recharge or maintain optimum battery condition. The four modes are BOOST, NORMAL, STORAGE and DESULFATION. The Converter Status Remote Pendant will show you which mode the converter is operating in.
