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

网友回答：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~）

网友回答：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.
