    Inverter Split-Phase Output Terminal Description

    Inverter Charger Split-Phase Output Terminal Connection

    Tips: What's the role of MPPT for Inverters?

    MPPT, or Maximum Power Point Tracking, refers to the inverters adjust the output power of photovoltaic arrays according to the different environmental temperature, illumination intensity and other characteristics to make the photovoltaic arrays always output the maximum power.

    Because of the external factors such as light intensity received by the solar cell and environment, the output power of inverter is changing. And more electricity the light intensity emits, the inverter with MPPT will make better use of the solar cell and make it run at the maximum power point. That is to say, the output power of the inverter with MPPT is higher than that without MPPT when the solar radiation is constant. This is the role of MPPT.

    Suppose that the output voltage of the component is 500V before MPPT starts tracking. After MPPT starts tracking, it begins to adjust the resistance of the circuit through the internal circuit structure, so as to change the output voltage of the component and the output current until it reaches the maximum output power (assuming 550V maximum), and then it keeps following. In this way, when the solar radiation is constant, the output voltage of the module at 550 V will be higher than that at 500V, which is the function of MPPT.

    Pure Sine Wave Inverter battery usage
    1) If I select "lithium" battery, does that mean this unit will work with LiFePO batteries?  
    2) The users manual wiring diagram for a battery bank shows a unit with 2 positive and 2 negative connectors?  
    Will this unit work for a 48-volt bank composed of four 12-volt batteries wired in in series?

    ATO Responded
    1. Yes, the device can be used with LiFePO batteries as long as the voltages match.
    2. Yes, this unit work for a 48-volt bank composed of four 12-volt batteries wired in in series.
    Normally there are only 2 terminals for connecting the battery voltage, one positive terminal and one negative terminal.
    Nice 1000 watt inverter charger
    This 1000 watt inverter charger is very suitable for my life and work. It's pure sine wave, which is nice. Low battery and overcharge, real-time LCD display. I will order more.
