3. atically reconnected Protection against overcharge Exceeding the final charging voltage leads to the formation of gas Gassing leads to the loss of electrolyte inside the battery and can also cause the formation of detonating gas through creating hydrogen Due to the loss of electrolyte the plates inside the battery are not covered completely which can lead to battery damage In case you experience gas formation eliminate the cause of the problem please check chart for faults and check the electrolyte level The amount of gas depends on the temperature The inbuilt temperature sensor automatically regulates the final charging voltage in accordance with the temperature in the area of use operation The battery is not fully charged when the final charging voltage is reached The charging current is then reduced just to the level that the final charging voltage is not exceeded The charging process IU charging recharges the batteries evenly and quickly The PSC charge controller uses PWM Pulse Width Modulation series regulation e g the charging limit is regulated by modulating the charging current coming from the solar module Therefore other charger types can also be connected additionally to the PV input terminal Gas control An over extended use of lead batteries without a controlled gas formation can lead to the development of damaging lead sulphate layers The Solar Charger Unit controls the gas formation and therefore prevents the deve
