Charger of the company Aca suitable for installations up to A at V. It is a type MPPT. MPPT charge controllers determine the appropriate battery charging levels, providing small losses in their actual performance. Compared to PWM controllers that distribute about 80% of the generated energy from the solar panel to the batteries, the remaining energy of about 20% is lost because simple PWM charge controllers do not detect the maximum power point of the solar panel. Also, the smart functions of an MPPT controller regarding battery charging and equalization guarantee better charging and maintenance, resulting in an extended battery life. Based on the above, MPPT charge controllers are ideal for larger systems where it is worth the additional collection of 20% or more energy and for cases where the voltage of the solar array is significantly higher than the battery voltage, e.g. using home panels.
