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. The pendant plugs into the standard accessory port on the Inteli-Power Converter. .
