Dual Mode Inverter Battery Charger


Here is a dual charger for Inverter battery. It can charge the battery via Solar panel as well as from AC power to keep the battery always in top condition. Even though a 12 volt Solar panel gives around 20 volts in full sunlight, it is available only three or four hours in a day. During the remaining hours, the intensity of light is very low and the condition worsens in cloudy and rainy days. This results in incomplete battery charging that ultimately leads to memory effect and permanent damage of the battery. This charger shifts the charging to AC mode when the voltage from solar panel reduces below 12 volts and restores the solar charging when the sunlight is sufficient enough again.
