If the voltage range of the iron-lithium battery is 360~480VDC, 360\/1.414=254, the transformer ratio can be determined as 200.

On the premise that the grid-connected switch can be controlled remotely, the power conversion system sends an instruction to open the grid-connected switch when it is running from grid-connected to off-grid operation.<\/p><p>When the off-grid to grid-connected operation is issued, an instruction is issued to close the grid-connected switch (the closing condition is judged by the converter, and cannot be closed manually); Supercapacitor charger function (C): When the power conversion system is connected to a supercapacitor product, it can start charging the supercapacitor from 0 voltage, and perform charging and discharging when the supercapacitor voltage reaches the operating voltage, replacing the role of the traditional charger.<\/p><p>After reading this article, if you need to know
