5. damage the batteries The amount of gas developed within the battery depends on the temperature The inbuilt temperature sensor automatically regulates the charging voltage in accordance with the temperature in the area of use operation The battery is not yet fully charged when the charging voltage is reached The charging current should not be completely switched off instead reduced so that the charging voltage is not exceeded This is accomplished by the Solar Charger Unit The charging process U charging recharges the batteries evenly and quickly The U charging is achieved by a very quick temporary short circuiting procedure also known as the pulse width modulation PWM shunt procedure Gas control function As a factory setting the regulator charges the battery with a 14 5V boost charge voltage When this voltage is reached the controller reduces it charging voltage to 13 7V float charge voltage which will be maintained until battery voltage sinks to 12 4V when the regulator start charging again with 14 5V Some sealed lead acid battery types require lower than 14 5V charging voltage as higher voltage would cause undesirable gas formation within the battery Please consult with your battery manufacturer about the max battery charging voltage if unsure In case you should reduce the max charging voltage you have the possibility to activate the built in gas control function see gas control activation section By doing so the
