I. How to set up the battery for closed-loop communication?

Closed-loop communication configuration usually involves two parts: battery setup and inverter setup.

Take the communication between the SRNE series inverter and the Server Rack series battery as an example:

1. Identify the pinout for the communication port on both the inverter and the battery, then select the correct communication cable and connect them.

Pinout on the inverter side(Taking the 5kW model as an example):

Battery pin description:

Select the appropriate communication cable

Complete the battery-side setup by referring to "How to Set Up Master-Slave Communication for the Battery".  Then follow the inverter’s user manual to configure the inverter side (example given for SRNE series inverters).

II. Troubleshooting & Tips

Q: Inverter shows “Communication Failed”

A: The reverse control setting is wrong, the wiring is wrong , or the protocol /pin does not match . Check the reverse control terminal settings, check whether the battery protocol is set correctly, check whether the wiring is correct, and check the manual to check whether the pins match.

Q: Multi-battery communication is unstable

A: Absence of a master/slave hierarchy or wiring crosstalk—ensure DIP-switch addresses are correctly set (one master, multiple slaves), use shielded cables, and route the wiring according to best-practice standards.

Q: Communication intermittently drops or fails

A: Interference in the environment or the wiring is aging /damaged. Use shielded wire instead , check for loose or oxidized terminals , and check if the communication line is damaged.

Closed-loop communication not only improves the efficiency and safety of energy storage systems, but also enables intelligent control, remote scheduling, and system linkage. To achieve reliable closed-loop control, it is recommended to use cables and protocols recommended by ECO-WORTHY to maintain battery and inverter firmware updates. Prioritize brands with verified compatibility.
