1.1 Wiring Diagram
Note:the following is the wiring diagram of EPS BOX TP. It is necessary to connect the ON-GRID side of EPS BOX TP to
the power grid, connect the EPS port to the EPS port of the energy storage machine, and connect the LOAD port to the
load at home. The function of TP is to select the power of the load port from the GRID or the EPS port of the energy storage
machine.
