AI回答:
这句话是在描述一个产品或设备的性能。它表示在额定功率下,谐波总输出电压的百分之三,在功率因数-1到+1范围内。谐波是一种频率是基波频率整数倍的电压或电流成分。该句话的意思是,在正常工作时,设备的谐波输出电压应保持在总电压的3%以内,并且在功率因数范围内。功率因数是描述电路中有关有用功率和视在功率之间关系的参数,取值范围通常为-1到+1。

    inverter 在43伏特就断电了,而不是你说的42伏特  FYR only

    感谢您的回复!
    现在您找到我,那就证明我推断换流器/反相器无法接通43V直流电,而是你确认过的42V的说法并不是完全错误的.
    请帮忙跟贵司的技术员确认有没有可能在控制器上调整设定值?
    希望尽快到贵司的回复!

    (以上纯属个人理解,如有错漏,烦请各位大虾多多指点,哈哈~)

    Thank you for the quick reply.
    Now you get me. That means i was not very wrong when i reasoned that the inverter will disconect at 43v rather than the 42v you just confirmed.
    Is it possible to adjust this setpoint on the controller?
    Please confirm this with your technician.
    Looking forward to your usual quick response.
