The MSH M Series is equipped with a PFC Power Factor Corrected and PI 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 Shorepower 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 After the transfer relay has closed the inverter s battery voltage is monitored to determine the charging stage If the battery voltage is low lt 12 8 VDC 12 volt models or lt 25 6 VDC 24 volt models the charger begins Bulk charging If the DC voltage is high gt 12 8 VDC 12 volt models or gt 25 6 VDC 24 volt models the charger will skip the Bulk and Absorb charge stages and go directly to Float charging However if the incoming AC power is lost and 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 MSH M S
