  • Protection Functions of BPlus inverter

    We designed extremely sound and intelligent protection functions for BPlus series pure sine wave inverter.


    BPlus inverter has red and blue indicator lights to show three different protection states. If the inverter is over-load, its red light will flicker; if the inverter is under-voltage, its blue light will flicker; if the inverter is short-circuit, over-temperature or over-voltage, its red light will stay on. Apart from indicator lights, LCD display also shows various inverter states to let customers know system running conditions directly. And all above protection information will be sent to specified device through MODBUS communication.


    As for short-circuit protection, we made special optimization:
    First short circuit: recover after 30s since start protection;
    Second short circuit: recover after 30s since start protection;
    Third short circuit: recover after 30s since start protection;
    Fourth short circuit: do not recove.


    Battery Under-voltage, Over-voltage Protection (12V)
    1.Under-voltage alarm: 10.5V;
    2.Under-voltage protection: 9.5V (under-voltage will not recover).


    Over-load Protection
    First over-load protection: recover after 30s since start protection;
    Second over-load protection: recover after 30s since start protection;
    Third over-load protection: recover after 30s since start protection;
    Fourth over-load protection: do not recover.

    Value every detail to provide stably running inverter.

I would like to take the floor.
