DC220V(200A-300A) solar controller

DC220V(200A-300A) solar controller

PWM is charging automatically changes the duty cycle of the pulse current charging the battery, so the battery charging pulse can make more safe and fast full of electricity, the battery disconnect period produced by the chemical reaction of hydrogen and oxygen compounds and have time to be absorbed, the concentration polarization and ohmic polarization naturally get rid of, so as to reduce the internal pressure of the battery, the battery can absorb more power. The pulse charging method makes the battery have sufficient reaction time, reduces the amount of gas evolution and improves the acceptance rate of the battery for the charging current.

  • Detailed description

    JAJE DC220V(200A-300A) solar controller

    JAJE DC220V(200A-300A) solar controller

    The JAJE series solar controller adopts type pulse width modulation (PWM), advanced PWM wide range of 0 to 100% of the adjustment can be charged any system under the condition of the battery fast and stable.

    PWM is charging automatically changes the duty cycle of the pulse current charging the battery, so the battery charging pulse can make more safe and fast full of electricity, the battery disconnect period produced by the chemical reaction of hydrogen and oxygen compounds and have time to be absorbed, the concentration polarization and ohmic polarization naturally get rid of, so as to reduce the internal pressure of the battery, the battery can absorb more power. The pulse charging method makes the battery have sufficient reaction time, reduces the amount of gas evolution and improves the acceptance rate of the battery for the charging current.

    JAJE DC220V(200A-300A) solar controller
