charge controller Altek ACM 20D + USB - it is one of the elements in the renewable energy system, namely in the solar system, which actually consists of solar panels, controller, battery and inverter. charge controller Altek ACM 20D + USB function performs filing on the battery current larger than the self-discharge current to compensate for self-discharge of the battery, but less current than the maximum charging current to prevent battery damage.
Solar cells convert solar energy into electrical DC power which passes through Altek ACM 20D + USB charge controller is stored in batteries and then transformed by the inverter, a DC voltage of 12 V into an alternating voltage with 220 V is applied to the load.
charge controller Altek ACM 20D + USB significantly increases the service life of batteries by controlling the charging and discharging of the battery. charge controller Altek ACM 20D + USB controller is a pulse width modulated charge current that achieves maximum capacity batteries
charge controller Altek ACM 20D + USB has the following characteristics:.
