I Proportional Integral multi stage battery charger The PFC feature controls the amount of power used to charge the batteries to obtain a power factor as close as possible to 1 or unity This causes the battery charger to look like a resistor to the line forces the charge current wave shape to mirror the voltage wave shape The PI feature allows the charger voltage and current to change independently These two features maximize the real power available from the AC power source i e utility or generator which translates into less power wasted and greater charging capabilities than most chargers today When an AC source is connected to the AC input the inverter begins monitoring for acceptable AC voltage Once the AC voltage is accepted the AC transfer relay closes and the charge mode begins After the charge mode begins the inverter s battery voltage is monitored to determine the charging stage If the battery voltage is low lt 12 8 VDC the charger begins Bulk charging If the battery voltage is high 212 8 VDC the charger will skip the Bulk and Absorb charge stages and go directly to Float charging However if the incoming AC power is lost but returns within 2 minutes the charge mode returns to the charge stage it was in prior to losing AC input regardless of the battery voltage The multi stage charger in the ME Series can use up to five different charging stages to help monitor and keep the batteries healthy The five stages incl
