The detailed steps of modifying the agreement are as follows:
1. The inicial page displays the default protocol of the battery. If it needs to be modified, first click
"Enter" and the first number is in the flashing state. At the time, enter the RS485 protocol selection
state. Select the corresponding number or letter through the "up" key / "down" key and compare with
the
Communication Protocol List
in the above table, so as to select corresponding inverter protocol
(RS485) is required. The selection numbers/letters range is 15 bits(0-D).
2. After selecting RS485 protocol, click "Enter" to automatically jump to the third number. At the
time, the third number is in flashing state and enters the CAN protocol selection state. The selection
range is 15 bits(0-D). Select corresponding inverter protocol (CAN) is required by pressing "up" key
