and fix the base to the wall
Battery
The base

10
②. Battery installation
Place the battery on the base, and secure the base and the battery together with an electrical
screwdriver and screws (M5*8)
③. Power line installation
The positive terminal of the battery is connected with the positive terminal of the inverter;
Connect the negative terminal of the battery with the negative terminal of the inverter;
When installing the connecting equipment, make clear the position of the positive and
negative terminal posts of the system, connect the positive terminal with red wire, and
connect the negative terminal with black wire to ensure that there is no wrong connection.

11
④.Communication line installation
Connect the RJ-RS485 /CAN port of the battery to the BMS communication port of the
inverter using a network cable.Dial the ID to "1" (see Table 3.2).
If a single battery is used, follow this step. If multiple batteries are used in parallel, set each
battery's address code according to Table 3.4, and connect the RJ-45 to RS485
communications ports in sequence. Connect the RS485 port on the first or last battery module
to the BMS communication port on the inverter.
