  • Over temperature protection
  • DC over-voltage protection
  • Battery overcharging protection

Three-Stage Charging

Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current delivered to the batteries in three automatic stages:

  • Bulk: Replaces 70-80% of the battery’s state-of-charge at the fastest possible rate
  • Absorption: Replenishes the remaining 20-30% of charge, bringing the battery to a full charge at a  slow, safe rate
  • Float: Voltage is reduced and held constant in order to prevent damage and maintain batteries at a full charge

Power Factor Corrected (PFC) Charging

Less shorepower is required for charging batteries, freeing up more usable AC power for running  electrical devices and appliances and reducing the likelihood of tripping shorepower breakers.
