EG4 Electronics www.eg4electronics.com BATTERY EQUALIZATION The equalization function is added into charge controller. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery.
EG4 Electronics www.eg4electronics.com CLEANING AND MAINTENANCE FOR ANTI-DUST KIT Overview Every inverter is already installed with anti-dusk kit from the factory. The inverter will automatically detect this kit and activate internal thermal sensor to adjust internal temperature.
