Two Lg resu10 communication

[covino88]

I'm having issues connecting 2 LGchem resu10 batteries to the storedge 7600 inverter. I can get one or the other to connectbut not both at the same time. I have 30pv, storedge7600 and the 2 batteries, Grid tied. I've spent days on this.

What firmware do you have on the StorEdge? Two batteries is only supported on FW 3.2305 (and newer).

When adding multiple batteries, each one will need to have its own address. [LG 14 or LG 15] LG Chem provides a separate part number for the primary battery and the secondary battery. Contact LG Chem for more information.


To program the inverter to run on 2 batteries, you just need to add each battery into the Battery 1 and Battery 2 fields under Communication | RS485-1 Conf.

I learned that the supplier sent a master and master not master and slave battery. The firmware is up to date

I learned that the supplier sent a master and master not master and slave battery.

That would be the address part. So I assume it is fixed now.
