    Inverter common fault contents and solutions

    May , 11 2024
    As an important component of the entire power plant, inverters can detect almost all power plant parameters for both DC components and grid connected equipment. If there is an abnormality, the health status of the supporting equipment in the power station can be checked through the feedback information from the inverter. Below are some common fault information and handling methods for photovoltaic...

    What is the meaning of float charging for intelligent three‐stage charger in battery charger?

    Jul , 12 2024
    Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

    Lithium battery life The reason for the slow charging speed

    Dec , 13 2024
    1. Electrical problems: Insufficient power of the charger is one of the common reasons for slow charging speed. If the output current of the charger used is small and cannot meet the maximum charging current requirements of the battery, the charging speed will be limited. For example, a lithium battery mobile phone that supports fast charging, the original charger output current is 3A, and the cha...

    Difference between kVA and kw

    Mar , 15 2025
    kVA is the unit of apparent power and kw is the unit of active power. In alternating current, apparent power does not indicate the actual power consumed in the circuit, but rather the maximum power that can be supplied or the maximum active power consumed in an alternating current circuit. In the case of active power, it is the power needed to enable the equipment to work properly, such as the ele...

    How electrolytic capacitor work for industrial battery charger

    May , 16 2025
    I. What is electrolytic capacitor: 1. Electrolytic capacitor, as the “energy storage heart” of charger power module, bears the key tasks of filtering, voltage stabilization and transient response. Its large-capacity characteristics (up to tens of thousands of μF) can effectively absorb the pulsating current after rectification, reduce output ripple, and ensure that the charging process is stable a...
