The invention provides an off-grid inverter control core module and a battery replacement cabinet with an off-grid inverter. The battery replacement cabinet comprises the off-grid inverter control core module, a battery parallel acquisition device and a power failure automatic switching power supply device. N input ends of the battery parallel acquisition device are respectively connected with N batteries, and an output end of the battery parallel acquisition device is connected with an input end of the off-grid inverter control core module. The output end of the off-grid inverter control core module is connected with an external power supply socket and one end of a power failure automatic switching power supply device, and the other end of the power failure automatic switching power supply device is connected with an electric leakage protection and main control device of the battery changing cabinet. According to the invention, the electric energy of the battery can be reversely inverted into the mains supply for other peripheral equipment to use, and the internal battery can be automatically switched to supply power to the battery replacement cabinet during power failure, so that more purposes of the battery replacement cabinet are realized. The power conversion cabinet can provide 220VAC power supply guarantee for municipal power utilization facilities or commercial tenants in case of power failure and emergency, and has social value and significance.
本发明提供一种离网式逆变器控制核心模块及具备离网式逆变器的换电柜,换电柜包括离网式逆变器控制核心模块、电池并联采集装置和停电自动切换供电装置。电池并联采集装置的N个输入端分别连接N个电池,输出端连接离网式逆变器控制核心模块的输入端。离网式逆变器控制核心模块的输出端连接对外供电插座和停电自动切换供电装置的一端,停电自动切换供电装置的另一端连接换电柜的漏电保护和主控装置。本发明能将电池电能反向逆变成市电,供其他外围设备使用,还能在停电时自动切换成内部电池给换电柜供电,实现换电柜的更多用途。本发明的换电柜在停电而又紧急情况下,能为市政用电设施或者商户提供220VAC的供电保障,具有社会价值和意义。
